Video isn’t necessarily a winner

Cisco has been attempting to kick start the video market for ten years, especially IPTV (that’s why IP Multicast still exists). The telepresence stuff hasn’t been profitable yet, and videoconferencing market is so dire that Cisco went a bought Tandberg to pump some cash into it.

To date, video looks like a loser. But Cisco is obviously not giving in.

It’s not Innovation

Google produced the hardware design for all the silicon and sent out reference units. Google produced the Android Operating System, seeded it and marketed it. Developed and tested an API. Then made it open source (and it’s based on Linux).

Google has created and promoted a community that will develop for Android so that Cisco can buy cheap developers.

Hardware can be manufactured by existing contract manufacturers so the Cisco doesn’t evan value add to that part.
Cisco does the following:

• Design some plastic to go around the CPU, RAM and battery
• Cisco writes the equivalent of Microsoft Word for Windows that integrates with existing IP Telephony platforms that they already have. This includes APIs for third party developers.

And that’s supposed to be innovation ?

It’s not Shipping

• Cisco says 2011. Recent experiences in manufacturing and delivery problems
• If you can’t deliver one switch that costs quarter of a million dollars, that’s already designed and in production how can I believe this date ?
• The world can change between here and next year.

Did I point out it’s not shipping. And Cisco can change their mind at any time. Be very careful.

It’s not the first

It’s not the first Android tablet announced, and many will be shipping before the end of the year. It’s won’t look so cool when it’s “just another tablet”

Cisco, Apple and Facetime.

I speculate that Cisco and Apple will get together and integrate Facetime into IP Telephony. Facetime is already SIP enabled, and only needs a small amount of work to access a directory service.

And Apple got to use the name “iOS” with Cisco’s permission, what’s the payback ?

Keep Cool People

No really. It’s not exciting. The show isn’t over until the fat lady sings and so far it’s only the first act.

The EtherealMind View

Look, how hard was this to do ? Cisco has invested almost nothing to make this product. They have access to the manufacturing, a team of developers in India and an existing market to sell the product to.

This isn’t innovation. This is ME TOO, I want to follow the market and make computers like HP and IBM.

Mark my words, when you have Servers in the Data Centre and Tablet on the desk, then Desktop PCs are just around the corner.

I try and avoid licensing at all costs, it’s a horrible subject and one that strikes fear in to many.  When you add virtualisation in to the mix it tends to get a little more complicated and you often find that the rules change on a reasonably regular basis. I was involved in a discussion today about Citrix XenDesktop and an interesting point came up when discussing licensing Virtual PCs.  Someone mentioned something called the Microsoft VDA,  I hadn’t a clue what they were talking about so I did a little digging around to find out more.

In summary this is what I found, it’s not pretty reading. As of the 1st of July 2010 Microsoft is changing the way it licences the Windows OS in VDI environments.  The following changes will take place

Windows® Virtual Enterprise Centralized Desktop (Windows VECD) and Windows VECD for Software Assurance (SA) will no longer appear on the price list.

Virtual desktop access rights will become a Windows Client Software Assurance benefit. Customers who intend on using PCs covered under SA will now be able to access their Virtual Desktop Infrastructure (VDI) desktops at no additional charge.

Customers who want to use devices such as thin clients that do not qualify for Windows Client SA would need to license those devices with a new license called Windows Virtual Desktop Access (Windows VDA) to be able to access a Windows VDI desktop.Windows VDA is also applicable to third party devices, such as contractor or employee-owned PCs.

What does it all mean?

In it’s simplest terms you don’t licence the windows virtual machine itself, you instead licence the end point its being accessed from. To further break this down there are two distinct endpoint categories to consider.

1. The end point is a Windows OS covered by Software Assurance (SA)
2. The end point is a non windows device or is a windows device without SA

In the first category you are covered to access a windows virtual machine as Virtual Desktop Access (VDA) is included as a Software Assurance benefit.  In the second category however you need to purchase a VDA subscriptions for each end point device.  Unfortunately this is not a one off purchase either, this is a $100 per year per device subscription cost.

As an example, say you have  a sales person who uses a company laptop and a company smart phone to access their VDI virtual machine.  You would need to have the laptop installed with a software assured copy of windows and buy a VDA subscription for the smart phone.  Alternatively if you have a non SA copy of windows on the laptop you need 2 VDA subscription licences to cover both devices.  This latter example would obviously be the same if the laptop was MAC OS or Linux based.

There is some good news though in that Microsoft have something called extended roaming rights with the windows VDA licence.  In short the primary user of a VDA licensed device can access their VDI desktop from any device that is not owned by the users company.  Examples would be a users home PC, airport kiosk or hotel business centre

There is a lot to take in with licensing, especially in the VDI space. I suggest everyone running or planning to deploy VDI takes a look at the recent changes and considers how they effect existing or planned deployments.  Some people will see this as Microsoft stifling the growth of Virtual Desktop Infrastructure, others will argue that it may actually acts as an enabler.  In truth I’m just not sure. I’m still digesting what it all means and playing through the various scenarios and combinations of VDI access.  On the surface I can see it hindering as opposed to helping this growing virtualisation sector.

Additional Information

For additional information I’d recommend checking out the following Microsoft FAQ article and for those of you who are Gartner customers the linked article below breaks it down quite nicely into simple terms.

The virtualization community, my employer, and every Virtualization Service Provider I know is neck deep in virtual desktop infrastructure (VDI). Already important because of Windows 7 migrations, the announcements last week from Microsoft and Citrix seemed to have raised the intensity of an existing white hot spotlight on VDI. When Microsoft, the world’s leader in the desktop operating system market, decides to change their position to make it easier to implement and license virtual desktops then we all have to stop and understand what has happened. There has been a significant change, and there are good things in the future for those moving to virtualized Windows desktops. However, understanding exactly what these changes are and how they impact us continues to be a moving target changing rapidly each year.

This post is my summary of research about the latest Microsoft and Citrix announcements. I’m linking and quoting several bloggers and analysts to help VM /ETC readers (and myself!) digest the details of the new licensing and promotions. I also the outline the actual products that make up the Microsoft and Citrix VDI solution, and then finally point to some interesting reactions and perspectives published over the last several days.

New Microsoft VDI Licensing

Most importantly, Microsoft declared a new licensing policy where Windows desktops will no longer need a separate license to be accessed via VDI by companies with Software Assurance. Although I could not specifically find it stated anywhere I looked, I assume this means whether accessed on any Microsoft VDI solution, VMware View, Citrix XenDesktop, or any other vendor’s VDI product. Here’s some additional information on the new licensing as intrepreted by others:

Desktop Virtualization: Microsoft, VMware in Cost Smackdown

http://www.networkworld.com/news/2010/031910-desktop-virtualization-microsoft-vmware-in.html?page=1

“One key part of the sweeping announcements, covered in an hour-long Webcast, is a simpler and cheaper model for licensing Windows in a virtual desktop environment. Specifically, on July 1, Software Assurance customers will no longer have to buy a separate license to access Windows via a VDI.

Moreover, for customers that use devices that don’t qualify for Software Assurance, such as thin clients and PCs used by contractors, there will be a new license called Windows VDA (virtual desktop access) available for $100 per device per year. This license will allow users to still have access to their complete virtual desktop outside the corporate network on devices such a personal laptops and airport kiosks.”

Maybe Microsoft is finally starting to abandon the concept of anchoring a Windows license to hardware and hopefully beginning to consider introducing virtualization editions of their operating systems? We are definitely not there yet, but at least it’s movement in the right direction.

Microsoft and Citrix VDI Promotions

Along with the new VDI licensing Microsoft and Citrix has also introduced some competitive promotions not only stimulate VDI migration but hopefully capture back some market share in the process. A new web site, citrixandmicrosoft.com, details these new offers.

First is the VDI Kick Start

”Get started with VDI for only $7K¹

Interested in VDI? Kick start your VDI implementation today and save 50% on Microsoft VDI Standard Suite and Citrix XenDesktop VDI Edition. With the VDI Kick Start promotion, eligible customers only pay $28 per device² for up to 250 devices, giving them the opportunity to launch a VDI implementation for only $7K¹. The offer includes Microsoft VDI Standard Suite subscription and Citrix XenDesktop VDI Edition annual licenses”.

Second is Rescue for VMware VDI

“Get the best virtual desktop solution – for FREE³!

Struggling with VMware VDI? Replace your VMware View licenses today with the best virtual desktop solution from Microsoft and Citrix VDI – for free³. Through the Rescue for VMware VDI promotion, eligible customers can trade-in their VMware View licenses with same number of Microsoft VDI Standard Suite subscription and Citrix XenDesktop VDI Edition annual licenses, up to a maximum of 500, at no cost^3”.

Go to the citrixandmicrosoft.com site to see the details of the footnotes in the quotes above. Both promotions are good until December 31, 2010.

Microsoft MSD VP Brad Anderson blogged about the promotions on the Windows Team Blog. Anderson’s post likens the “Rescue from VMware VDI” program to recent US Government attempts to stimulate the auto industry.

“One piece of news that I’m most excited about that helps with this is the “Rescue for VMware VDI” promotion we’re offering with Citrix. Think of it as a Cash for Clunkers trade-in of VMware View licenses to Microsoft VDI Standard Suite and Citrix XenDesktop VDI Edition licenses at no additional cost.”

What Makes Up the MS & Citrix VDI Solution?

So what exactly is the Citrix and Microsoft VDI solution? A picture is always a faster way to visualize all the components, and I took the following one from the Citrix and Microsoft Brochure:

To complete the picture is The Microsoft Windows Enterprise: Virtual Desktop Infrastructure web page which contains a lot of MS VDI solution information, but is also the source of the following breakdown of MS VDI Standard and Premium Suite components:

The Microsoft VDI Standard Suite will include licenses to the following technologies:

1. Hypervisor platform (Hyper-V Server 2008 R2)
2. An integrated management suite for VDI (System Center Virtual Machine Manager 2008 R2, System Center Operations Manager 2007 R2, and System Center Configuration Manager 2007 R2)
3. Microsoft Application Virtualization through the Microsoft Desktop Optimization Pack (MDOP)
4. Connection Brokering capability through Windows Server 2008 R2 Remote Desktop Services.

The Microsoft VDI Premium Suite includes all the features of the Microsoft VDI Standard Suite, and also includes:

1. Complete Remote Desktop Services capability, including the option to deploy session based desktops in addition to VDI desktops.
2. Microsoft Application Virtualization for Remote Desktop Services

Note that both the VDI Kickstart and the Rescue For VMware VDI offers are for the MS VDI Suite only.

Reactions and Perspective

Of course, after exciting news like this there are those that can look beyond the fanfare and raise some questions. Here’s several links worth following for a deeper analysis that helps provide a better understanding and point out the areas still needing improvement.

chriswolf.com

A User-centric Microsoft Licensing Model? Not Yet, but Getting Closer

“Looking past the good news that came out of yesterday’s announcement, considerable work remains. Microsoft has still not addressed the service provider market. Considerable clarity is still needed for licensing virtual desktops on shared infrastructure. For example, if a user needs a Windows desktop for a week, he essentially has to pay for 90 days worth of licensing. Why? Even with VDA, the service provider technically has to associate the VDA with the subscriber’s physical device and can’t transfer it for another 90 days. The result is that desktop-as-a-service (DaaS) is far more costly than it should be. This problem will grow once companies like HP, IBM, and Dell offer client hypervisors, and look to offer services where user desktop VMs are automatically replicated from their personal system to the cloud.”

simonbramfitt.com

The sleeping giant awakes – Microsoft gets desktop virtualization right

“Admittedly there are still a few kinks to iron out with the VDA licensing model. Most notably there is a problem with the way that Microsoft handles the difference between “corporate” and “non- corporate” devices. Microsoft defines a corporate device as one that was bought by the organization. Any non-SA eligible endpoint owned by the organization that needs to access a virtual desktop must have its own Windows VDA license. Which, kind of makes sense until you start to move away from desktop devices and down to smart phones; at which point it gets ugly fast. This isn’t anything to do with functionality; you can do a lot with the right smart phone today.  It’s more a matter of the intersection of policy and accounting.

Looked at from a personal perspective, my iPhone is MY iPhone (so it’s non-corporate), but my colleague’s Blackberry was bought by Gartner (that makes it corporate). They both do the same job more or less; I get better apps, he can type faster. But when we look at using them for remote access it gets very messy.   I will be able to take advantage of my laptop’s Windows SA license to access my virtual desktop from my non-corporate device, but my colleague can’t use ‘his’ Blackberry to access that same environment, without an additional VDA license. Of course we could avoid this by giving him $100 and telling him to go and buy his own phone but that’s not the point is it?  Still, with a couple of months to go before the July 1st launch it’s possible that we will see further changes to address this flaw.”

Closing Thoughts

Be sure to read all of the links in this post for more information, but these last few quotes pose some interesting ideas and viewpoints that stood out to me.

J.Tyler Rohrer, founder and COO of Liquidware Labs’ Stratusphere tool being used by many VMware Partners to assess VDI opportunities, blogs that 2010 is now officially the year of virtual desktops

Microsoft VDI Inertia

“As we all sit around this weekend and try to figure out “what does this mean for vendor XYZ” – relax a bit. What this means, in my opinion, is that every vendor needs to sharpen their pencils, products, and presentations because this now IS, the year of VDI.”

Quoting a quote seems like a violation of journalistic ethics, but, hey, I’m a blogger! Besides, this quote on the competition for VDI market share was too good not to mention again.
Microsoft, Citrix lure VMware customers with cutthroat promo

“One desktop virtualization integrator, Tony Wilburn at IT services company Betis Group, called the promotion a “desperate” attempt to generate buzz. He also said it has the added effect of elevating VMware.

“Has Microsoft ever before had to partner with another company in order to take on a rival?” Wilburn said. “When the No. 2 and No. 3 companies in the industry have to team up to take on the No. 1 player, doesn’t that make the one player look even stronger?””

It appears to me that Microsoft and Citrix aligned together for VDI have a fighting chance. I expect a lot of interest will be generated from the incentives of these joint promotions.

Day 2 of HP Blades Day took place in a new location – the Customer Experience Centre.  This was due to issues with Wifi on day 1, now resolved in our new location.  Order of the day was:

• Review of the previous day’s presentations with a quick question & answer session
• Presentation on Client Virtualisation
• Factory tour

Client Virtualisation

Joseph George presented to the bloggers on client (aka desktop) virtualisation.  Whilst HP seem to have a story in this area, I’m skeptical about the whole process of virtualising desktops at this stage, other than in certain use cases.  I can see benefits for the following:

• High availability environments such as financial traders, where loss of a desktop translates to financial loss.
• Large scale desktop deployments where functionality is generic.  A good example of this is call centres; desks only require access to limited features (so don’t need high powered devices) and physical desktops may be used by multiple users.

Environments not suitable for desktop virtualisation will include mobile users and anyone running bespoke hardware or software with hardware dependencies.

HP pretty much accepted that hardware savings are not the main reason for virtualising.  This means a more intelligent model on TCO for desktops needs to be established, encompassing consequential loss through hardware downtime, processes cost for technology deployment and replacement and so on.  I think some of the thinking around security is a red herring as laptops are unlikely to be candidates for virtualisation and desktop data can be secured safely today.  I’ll be writing more on this topic over the coming weeks.

Factory Tour

We next moved on to a tour of the HP factory; this isn’t a manufacturing plant but rather purely an assembly line for server and storage components.  I’ve been on factory tours before and these days they pretty much leave me cold.  However HP had some interesting innovations to discuss.

• Customisation.  All HP server and storage builds are based on customer requests and so fully customised, including placing of kit into racks for shipping.  This means every configuration shipped is exactly as the customer ordered – and more;  HP also pre-cable the racks as the equipment is being installed.  Customers ordering multiple configurations can preview one rack of their order before the remainder are built.
• Testing.  Once servers are built, customers are provided the ability to VPN into their equipment while it is sitting on the factory floor.  They can perform load and performance testing before the equipment ships, saving valuable deployment time once the equipment arrives.
• POD (performance optimised datacentre).  This is HPs term for a datacentre in a container – which is exactly what they are.  Plug in power and cooling and you’ve a data centre on the move.  Except these devices aren’t really built to be picked up and moved around.  Rather they are aimed at providing temporary data centre facilities in scenarios where traditional data centres wouldn’t be possible – extension of existing facilities or perhaps creation of a data centre without planning permission were two good examples.

After the tour, we wrapped up at a local restaurant.

Overall the two days have been extremely informative and given me many subjects to blog about.  Look forward to more over the coming weeks!

Some very interesting articles on Drobo S and DroboElite

The Drobo Math

I totally love my Drobo but

PLEASE SEE THE ATTACHED PDF FOR PERFORMANCE DATA

Here are some performance stats collected with running Drobo as a direct attached storage and using some benchmarking tools to compile these results.  All the performance stats are collected using different criteria’s that can affect the performance of the Drobo. Also used various connection methods including USB and Firewire to obtain these stats.

The entire series of tests have been performed using Mac OSX 10.6.2 host with either USB attached or Firewire attached to the Drobo.

These results are limited to the Drobo and cannot be compared to the Drobo Pro or Drobo Elite or Drobo S.

The test were carried out with using various combination of drives, rebuilt data protection, best-case scenario, worst-case scenario, 1 drive, 2 drives, 4 drives, different drive cache & capacity.

Enjoy!!!

There was a lot of excitement when Google announced it’s intent to develop the Chrome operating system (Chrome OS). Almost immediately journalists, analysts, and bloggers began speculating if Google’s future OS offering could pose a threat to Microsoft’s dominance on the desktop. VMware quickly added clout to Google’s plans by promising to support Google OS. VMware also expressed interest in the Chrome OS being used to develop specialized applications as virtual appliances. However, the most compelling question and use for the new Linux based OS to me would be if the Chrome OS could become relevant in connecting to VDI solutions. I feel that Google’s immediate traction and ultimate success with an OS relies on it’s ability to install VDI clients – not as a Microsoft desktop replacement, whether physical or virtual.

VDI has gained momentum. VMware, Citrix, and Microsoft all boast about the availability of an enterprise ready virtual desktop management solution. Storage technologies such as thin provisioning, deduplication, and rapid cloning are being perfected and optimized and will lower the total cost of ownership for VDI. 64 bit Hardware with virtualization assist technologies on host servers has enabled record setting ratios of supported users. It seems that OS licensing models formerly based on physical hardware are slowly morphing to support virtualized environments. But, in my opinion, there is still a major hurdle to the enterprise’s wide spread acceptance of VDI on a platform other than Windows.

Is enterprise business really ready to migrate the majority of their user applications and data to Linux, the web, or even the Cloud? For Chrome OS to challenge Microsoft for seats in the enterprise, this shift will have to happen, and it will have to be publicly reported as highly successfully and common. Are web based applications and software as a service (Saas) alternatives ready to handle main stream business services like email and office collaboration? More importantly, are enterprise IT departments ready to allow cloud providers to run, protect, and store their business critical applications and data? When that happens the OS on the desktop becomes less important. The browser will become the only application of importance.

Until then, Windows will continue to be the most popular desktop OS simply because it runs the most popular applications needed by business today. Therefore, the typical VDI solution in the immediate future will continue to consist of Windows VMs. Microsoft’s decision to strip down the bloat and replace Vista with Windows 7 was a wise move, and probably has ensured Microsoft’s position as the desktop market leader for many more years to come.

That’s why it more important to think about what will the users use to connect to those virtual desktops. Yes, VMware, and the competition, is developing their own desktop hypervisor OS. VMware calls their work in progress CVP (Client Virtualization Platform), but is VMware’s CVP (for example) really going to be able to run on all modern notebooks and desktops? To be specific, on the Lenovo T400 I am using to write this, will a VMware client hypervisor allow all of the volume buttons, wifi adapter controls, microphone, blue tooth, and other miscellaneous hardware features to work properly? What about all the other manufacturers of notebooks, netbooks, and desktops with their different models and hardware configurations too? This is where all the work put in to a modern Linux distribution appears to have the advantage. Otherwise, does the future client hypervisors requiring their own specialized hardware really sound appealing? Does expecting users to use today’s notebooks without the full functionality sound realistic?

Assuming Google’s product will be most like a Linux distribution, it seems to me that Google’s best bet for mass adoption of the Chrome OS would be to make sure that enterprises can count on installing VMware’s View Client (and the competition’s VDI clients as well). The real corporate desktop will still have to be a Windows virtual machine that can be synced between the data center and the client OS and even used offline. Eventually, as cloud based application replacements emerge in the future, Google’s OS could become more of a direct competitor/replacement to Microsoft’s OS.

I’ve been meaning to write about the Citrix Branch Repeater product for some time now, so a timely reminder to actually do this was the release of Citrix Branch Repeater V5.5. Earlier this year I attended a branch office infrastructure event run by Microsoft and Citrix in Edinburgh.  This was the first time I had heard about this product, I luckily had the chance to follow up my interest at the recent Citrix iForum in Edinburgh.

Branch Repeater is the rebranding of the old WANScaler product, which, in its simplest form was a WAN acceleration product. The new branch repeater is still a WAN accelerator at heart;  however Citrix have added some clever branch office features as well as some new features for XenApp customers. From a topology perspective, you basically place a larger repeater appliance in your data centre and additional smaller repeater appliances in your branch office.  I was actually surprised to learn that this is not the only option available; there is also a repeater software plug-in for use by remote users.  The diagram below shows the basic topology overview.

Branch Office Operations

One of the most interesting aspects of the new branch repeater product is the branch-in-a-box concept.  You can purchase your Citrix Branch Repeater with Windows 2008 or Windows 2003 R2 built in.  This allows you to use your appliance to deliver DHCP, DNS, WINS, AD, DFS as well as file and print services through the onboard hard-drive.  Support for Microsoft’s read only domain controller configuration adds to the package, allowing you to actively consider consolidating an entire branch office infrastructure into one appliance.  Now it sounds like an appliance failure could have devastating consequences for your branch office and you’d probably be right.  It was one of the questions I had for the Citrix Consultants at the iForum, they informed me that you can cluster two appliances together for HA resilience.  Increases cost of course, but what price do you put on availability?

Citrix XenApp features

Citrix have added some nice features to encourage those of us who already use XenApp as a branch office delivery mechanism. ICA is already a very efficient protocol and Citrix have attempted to build on that with HDX IntelliCache and HDX Broadcast technologies.  HDX IntelliCache allows local caching and de-duplication of ICA traffic across multiple ICA sessions, it also allows for the local staging of XenApp streamed applications if that’s a technology you utilise.  HDX Broadcast on the other hand is the technology which optimises and gives granular control over the network elements of ICA.  The list of individual features is quite extensive so I won’t reproduce it,  you can check it out over at Citrix’s website by clicking the links above.  The benefits of the branch repeater when used with XenApp probably depend on the number of XenApp users in a branch or your current use of the technology. A branch with a small number of users may not see a benefit that justifies the cost, however  I can see immediate benefit if a branch office was to require expansion. Use these appliances and you probably wouldn’t need to change your WAN Links.  That has to work on the cost front!

Repeater Plug-in for Citrix Receiver

I mentioned the Repeater software plug-in earlier as this was one of the features that caught my eye, primarily because we have a lot of travelling Citrix users and home based users.  This part of the product set claims to “overcome bandwidth and latency limitations on WiFi, broadband and 3G Connections” while also delivering that high definition experience (HDX).  This in itself interests me enough to explore further, but then I find it also allows you to provide central administration of end devices covering software distribution and configuration settings.  It works seamlessly with the Citrix Access Gateway product and other leading VPN’s to optimise traffic within secure tunnelled network connections.  All in all it sounds brilliant and potentially allows you to deliver improvements for users who work outside the branch office, something that is becoming more common every day.

Conclusion

I mentioned before that this is a WAN Accelerator product at heart, with nice new shiny add-ons to meet a number of customer requirements.  I’m genuinely excited by this product as I think it has a place in companies global infrastructures, especially with remote data centres and Citrix based branch offices becoming more common place.  I myself am going to find this hard to sell to my current employer, mainly due to some nasty issues we once had with another WAN Accelerator called Riverbed.  However that was a long time ago and maybe the industry has moved on since then, maybe it’s time to take a fresh look.  Cost is the one thing I’m not 100% sure about at this point in time, there are a number of different models and it would appear that costs range from $5,000 for the branch side appliances to $11,500 for the data centre side appliances.

If anyone is using the Citrix Branch Repeater appliance, we’d love to hear about your experience of it and possibly you could clarify the cost element for us all.

The fact that Microsoft has embraced virtualization is an understatement. The fact that Microsoft has been slow to embrace other virtualization vendor’s capabilities to run Windows operating systems as guests is equally an understatement, but what if this wasn’t the case? That is, what if Microsoft abandoned the licensing strategy of anchoring Windows to physical hardware? What if the folks at Redmond recognized virtual hardware and virtual machines (VMs) as equals to physical devices when assigning licenses? Taking it a step forward, what if specialized versions of the various Windows operating systems and applications were specifically developed for VMs along with special licensing? Maybe it will never happen, but there have been a few signs recently that give one hope for the possibility.

Like crop circles, the following are some posts that caused me to wonder “what if?”.
 

First, there was a rumor about a virtualized version of Microsoft Office.
latoga labs – Rumor: Microsoft Office Virtualization Edition

“I heard an interesting rumor this week that Microsoft is planning on updating their licensing model in the near future for Microsoft Office to introduce a virtualization version. The way it was described to me is that if you want to migrate your physical desktops to virtual desktops and run Microsoft Office on them, you will need to purchase a special Office Virtualized Edition.”

Interesting no doubt, but the more I think about this rumor it really starts to sound like a reason to justify making companies pay for another Office license – as if the first Office license can’t P2V with the OS? I have not heard anything else since about “Virtualized Office”.

Next there was the  announcement that Microsoft has identified a market opportunity for a low cost version of Server 2008 designed to run on low-end servers. To fulfill this need, Microsoft released Server 2008 Foundation, which comes pre-installed on hardware when purchased through original equipment manufacturers (OEMs). Paul Thurrott’s post Windows Server 2008 Foundation Preview explains Microsoft’s vision for this version:

“Microsoft saw a glaring hole in its product line, one that was not filled by the consumer-focused Windows Home Server or the overly-functional SBS. This year, it’s possible to purchase perfectly capable low-end servers for well under $1000. So it doesn’t make sense that Microsoft’s lowest cost infrastructure server, Windows Server 2008 Standard, costs $500. Clearly what the company needed was something that offered core Server features but came in well under that price.”

Which makes me wonder if Microsoft would ever create a similar edition for virtual instances of server 2008?

Finally, the biggest news about a virtual edition of a Windows operating system was XP Mode in the upcoming Windows 7.

Again a post from Paul Thurrott along with Rafael Rivera - Secret No More: Revealing Windows XP Mode for Windows 7

“XP Mode consists of the Virtual PC-based virtual environment and a fully licensed copy of Windows XP with Service Pack 3 (SP3). It will be made available, for free, to users of Windows 7 Professional, Enterprise, and Ultimate editions via a download from the Microsoft web site. (That is, it will not be included in the box with Windows 7, but is considered an out-of-band update, like Windows Live Essentials.) XPM works much like today’s Virtual PC products, but with one important exception: As with the enterprise-based MED-V (Microsoft Enterprise Desktop Virtualization) product, XPM does not require you to run the virtual environment as a separate Windows desktop. Instead, as you install applications inside the virtual XP environment, they are published to the host (Windows 7) OS as well. (With shortcuts placed in the Start Menu.) That way, users can run Windows XP-based applications (like IE 6) alongside Windows 7 applications under a single desktop.”

My understanding of XP Mode is that it is a specialized VM edition of Windows XP.

What If?

Would it not be nice if a “Windows Server v12n Edition” existed? How about Windows Desktop V12N? Stripped of the extra drivers and applications. Licensed per virtual machine. Free to migrate between virtual hosts. Allow the hot add and remove of virtual RAM and CPU. Operating systems tweaked to be easily cloned for dynamic demand. Applications written so that they could be duplicated as needed with services that could self load balance. Able to leap tall buildings …

Is my head in the clouds, and, for that matter, are these crop circles just a hoax?

If you’ve been experimenting with ZFS, as we have, you’ve been struck by some of its limitations. One of the most common complaints is that it’s not flexible in terms of sizing – you have to add a whole new “vdev” (analogous to a RAID set) in order to expand, rather than simply adding new disks one at a time.

But there is one other way to expand a zpool – by iteratively swapping out every disk in the pool with a larger one and letting ZFS heal the pool. This is the technique demonstrated by Harry D in a two-part blog post:

1. How to resize ZFS
2. How to resize ZFS – Part 2 (the real world)

You still can’t shrink a zpool. Let’s hope that comes along soon, along with more flexibility in general. Otherwise, ZFS will be much less interesting in the desktop/workstation/small server space!

You’ve probably already heard about VMware’s open source VDI client. VMware’s official announcement for the VMware View Open Client was released on February 4. Touted as the next step for creating a universal client to be used on any device from anywhere, VMware releasing the client as open source enables technology partners to start to fufill the vision. In VMware’s words:

“Now, VMware is providing VMware View Open Client for partners, enabling them to use VMware View source code to optimize their products to deliver rich, personalized virtual desktops to users. In addition, partners will be able to use the source code to help accelerate the development and delivery of solutions for enterprises to provision and manage thousands of virtual desktops simply, securely and at substantially lower operating costs.”

What I find most interesting is that Linux systems now have a installable VDI client. Unless I am mistaken, previously a web browser was the only way a connection to a virtual desktop could be made from Linux. Not only does this increase the functionality and features, but it could substantially lower the total cost of a VDI solution. Whether using a thin client or a desktop computer, using Linux as the device OS generally should reduce the cost of implementation.

Looking forward, I’m curious to see if specialized distributions are developed that integrate the Linux VDI client. I would imagine a “VDI LiveCD” from Ubuntu, Suse, or even Google’s gOS could be released to minimize the installation and administration learning curve and adoption barriers. Ultimately, this client could be a native feature of a desktop hypervisor too.

For a screen shot of the VMware View Client on Suse desktop check out Duncan’s post VMware View Open Client, test it! » Yellow Bricks.

The linuxdevices.com post VMware ships open source Linux VDI client summarizes information about specific features and differences in the commercial and open source versions of the Linux client.

“VMware will continue to offer its commercially licensed View Client stack for Linux and Windows. The commercial stack adds features like USB redirection, multiple desktop sessions, and multimedia redirection. Like the commercial version, though, the free, open source View Open Client enables a Linux desktop or thin client to connect to a remote Windows desktop managed by VMware’s “View” virtualization software. The free client boasts a “full” command line interface, and is said to support secure tunneling using SSL, and two-factor authentication with RSA SecurID. The release is said to work with VMware Virtual Desktop Manager (VDM) 2.0 and 2.1, as well as VMware View Manager 3.0. Posted on Google Code, the client software is licensed under GNU Lesser General Public License version 2.1 (LGPL v 2.1).”

VMware employees have also blogged about the new VDI client. Check out Mike Dipetrillo’s post VMware View Open Client and John Troyer’s VMware releases open source desktop client.
