Market positioning Acadia, EMC, Cisco and the whole vBlock Idea

So a while back, Cisco, VMWare and EMC announced that they are forming a partnership to co-operatively sell and support products. This joint venture is named Acadia and is made up of a specifically screened and selected sales people and engineers from each company. What is particularly notable is that EMC and Cisco have committed in excess of $200 million to make it work. This tells me that they are serious about this project.

Then they added some of their best sales people to the mix including engineers and then went knocking on the doors of every large company in the world in a “no large customer left untouched” blitzkrieg of one on one marketing.

So What is Acadia made of ?

Acadia is offering a package of actual products (not PowerPoint releases) from EMC, Cisco and VMware using a marketing strategy called Vblock. At Boston Gestalt IT Field Day, we received an excellent presentation on the details around the Vblock package from Ed Sai and Scott Lowe that sparked a heated response. I felt that the key issues were around two points:

  • Why are the Vblocks so Large ?
  • What happens if you exceed the operational parameters of a Vblock ?

Because there was much discussion about why the Vblock that have some strict limitations, I wanted to look into why these limitations exist and why people would object so vehemently to them. And also talk around the question for why Vblocks are big. Too big for most people to buy.

Comprehending the Limits on the joint venture

Acadia is not a merger (yet) of EMC and Cisco, but a partnership focused on the Data Centre. The partnership only promotes selected product groups from each company and even specific products within those group. For example, a Vblock does not include a Nexus 7000 switch, only the Nexus 5000 / 6000 / 2000 as the edge switches. ( You would use your own backbone to connect to your Ethernet network and legacy FibreChannel network ). VMware does not offer VDI solutions. EMC offers CLARiiON in Vblock1, and Symmetrix in Vblock2.

These limits may mean that your choices are limited. Some people regard this as as major concern. I regard this as a reasonable trade off – good service, easy marketing against lack of choice and flexibility.

Other Companies

It’s worth remembering that the joint venture is not exclusive. Both EMC and Cisco are free to pursue partnerships with other companies, and both are actively seen partnering in the market with other companies. Thus recent Cisco / NetApp and EMC/IBM announcements could create a confusing picture for some people who don’t understand these dynamics. That said, from what I’ve seen the Acadia partnership seems to be a “big deal” for both sides with a lot of passion, commitment and, most importantly, significant amounts of cash that fund expensive marketing campaigns. In this case, marketing that seems to actually be relevant and useful.

Selected Products

Acadia only works with selected products from both Cisco, EMC and VMWare. That is, they only offers products from the Data Centre Business Unit from Cisco, selected products Centerra and Celera at EMC and VMWare vSphere. The product is positioned in the market as a private cloud so any technology not relevant to that message isn’t going to be considered eg. No firewalls, no edge routers, no wireless, no backup software, no deduplication,.

My perception is that clear business goals drive this logic:

  • Market clarity – limiting the product set allows Acadia to have a highly targeted product message, especially with the “cloud” buzzword attached.
  • Technical capacity to deliver an effective sales force
  • Leaves space for ‘other partners’ to have similar relationships with customers and not ‘upset’ the reseller marketplace
  • minimise the business impact if the project fails
  • customer want guarantees that it will work which should get better sales results.
  • Acadia has to deliver the solution and deliver the support promise. Not easy when so many technologies are involved, with so many competing interests

I particularly want to focus on the Technical Capacity and Customer Guarantees elements of the argument. If you figure that EMC, Cisco and VMware are bringing a group of vendor engineers together, think about the problems you might have: engineers may have little or no expertise outside of their own company or worked in a cross-functional team. To overcome these problems I would go for a narrow product selection and then expand it over time.

Remember that large companies create significant opportunities for ineptitude and incapacity. Layers of management can create indirection and misalignment just as easily as they can create opportunity and focus. Bringing together teams from three large companies could easily go wrong (case study – HP and it’s many divisions that are rarely coherent).

There are other topics, such as upsetting the resellers, market clarity are all pretty obvious and shouldn’t need discussion.

What are Vblocks ?

The Vblock components are the cumulative permissions of what the marketing and business limitations will allow. There are no technical limits to what equipment could be in a Vblock except for the ability of Acadia to provide a good level of support. These limits are somewhat onerous but not entirely unreasonable. There are currently two Vblocks defined (and more are planned) – known as Vblock 1 and Vblock Two, they are designed, tested and (as is the fashion) certified to within certain, rigidly defined performance levels.

Basic Components

The Vblock architecture is reduced to five layers of physical infrastructure and roughly shown in this diagram taken from “Vblock Infrastructure Packages Reference Architecture” released in 2010.

Outline Bill of Materials

Block type Compute Network Storage OS Management
Vblock 1 16 – 32 UCS B-series blades, 128-256 Cores, 960-1920 GB memory Cisco Nexus 1000V, UCS 6100 Fabric interconnects (LAN & SAN) EMC Clariion CX4-480, 38-64 TB capacty, EFD or FC or SATA drives, iSCSI or SAN VMware vSphere 4.0/vCenter 4.0 EMC Ionix UIM, vCenter, EMC Navisphere, EMC Powerpath/VE, Cisco UCS Manager, Cisco Fabric Manager
Vblock 2 32 – 64 UCS B-series blades, 256-512 Cores, 3072-7144 GB memory Cisco Nexus 1000V, UCS 6100 Fabric interconnects (LAN & SAN) EMC Symmetrix V-Max, 96-146TB Cacacity, EFD or FC or SATA drives, iSCSI & SAN VMware vSphere 4.0/vCenter 4.0 EMC Ionix UIM, vCenter, EMC Navisphere, EMC Powerpath/VE, Cisco UCS Manager, Cisco Fabric Manager

From this, you can see there is a fair amount of variation within the Vblock parts list to cater for your specific requirements. To quote Acadia :

A Vblock consists of a minimum and maximum amount of components that offer balanced I/O, bandwidth, and storage capacity relative to the compute and storage arrays offered. Each Vblock is a fully redundant autonomous system that has 1+1 or N+1 redundancy enabled by default.

In practice, Vblock 1 storage is scaled to deliver from ~42 TB/41000 IOPS (Min) to ~68 TB/ 50000 IOPS (Max). Vblock 2 storage is scaled to deliver from ~140 TB/92000 IOPS (Min) to ~211 TB/140000 IOPS (Max). The hardware is selected to match your performance requirements.

Other flexibilities

Some other quotes from the Cisco / EMC / VMware reference architecture guide:

For Vblock 1, there are no hard disks on the B-200 series blades as all boot services and storage are provided by the SAN. Hawever a snall hard drive may be installed if local page memory is required for vSphere.

For Vblock 2, each B-200 series blade module has 72GB SATA drive for page memory purposes. If required, these can be removed to reduce power and cooling overhead, increase MTBF or save costs.

The MDS9506 switches are recommended, but may optionally be changed for 9509 or 9513 to scale capacity or reduced to an MDS 9222i is less density is required


For Vblock 1, there are no hard disks on the B-200 series blades as all boot services and storage are provided by the SAN. Hawever a snall hard drive may be installed if local page memory is required for vSphere. If the local disk is user for main storage or operating system storage, it is not considered a Vblock and is a custom implementation at this point.

It is also acceptable for operating system and applications to be run directly on the B-200 series blades. It should be noted that other hypervisors are not supported by Vblocks and invalidate the Vblock support agreement (my emphasis)

The Limits are arbitrary, practical and mainly marketing

At the Boston Tech Field Day, we saw a number of questions on why there are limits, and what happens if you exceed the solution parameters. I believe it is a simple marketing reason – simple products, simple factors, easy to comprehend makes for a product that is easy for sales to sell, and even easier for customers to buy. Pricing is clear and unambiguous, and sales peoples will attempt to focus the customers away from price onto other topics. Like low power, special UCS features, ease of operation, etc etc.

The key factor is that the Cisco UCS server will be perceived by many as unproven. You can be sure that HP / IBM / Dell are going to work that Fear / Uncertainty / Doubt in a competitive situation.

Exceeding the Limits – You Certainly SHOULD

If you choose to exceed the offered the solution, then that is a simple choice. It’s not something to be particularly concerned about. Currently, we all build stacks of servers, storage and networks and provide our own support. Why would buying a guaranteed stack make any difference ?

These limits are to ensure that service guarantees can be met. The service guarantee exists to help customer to buy these products., it does not exist to make the products work. However, when the CIO is about to approve a purchase order for half million pounds they will be looking for a comfort level that it’s going to work. Those Cisco UCS servers are new and you want some assurance.

So once the system is working, feel free to head out in your own direction. Meeting the requirements of your business is more important that having a an end-to-end guarantee in overall picture. Remember, Cisco / EMC / VMware is still going to support each product using the same process that we have today.

The Fear of Lock In

My concern with the Vblock bundle is fear of lock in. The Cisco UCS product is a closed solution within the racks. Across the backbone of the Data Centre will also be Cisco Nexus 7000 switches for “best compatibility”. All server components must be purchased from Cisco who will be able to arbitrarily set the price. All and any server upgrades, and extra server must come from Cisco.

All storage vendors are an effective lock in today. The so-called “certification programs” ensure that EMC and other “chosen few” are restricted to the supply of drives and accessories.

If Cisco / EMC achieves a dominant position then they have the ability to control pricing. Since both companies are already dominant in their respective markets, and tend to “reassuringly expensive” price models, this is a well founded concern.

What does a Vblock physically look like ?

While every Data Centre is different, every rack looks pretty much the same. During my research, I have realised that a Vblock takes very little space in the data centre. In fact, it’s not until you see the amount of space that you realise the impact to

Vblock 1 – Racked

Vblock 2 Racked

A Vblock 2 is quite a bit larger and needs more storage. The server blades are larger (more CPU, more RAM per blade). I believe that the increased IOPS for the storage subsystem means that bigger storage units are needed. I think five racks is at the smaller side of the Vblock 2 possibilities.

Vblock expansion

Even though the Vblock is modular, you can bet that Acadia has a nice little pitch around expansion. Sure enough, it is spelled out in the Architecture Reference:

Caption Text.

Caption Text.(Click for a full size image)

As Vblocks are adde, the capacity of the Vblock scales either as an aggregated pool, whereby any ICS blade can access any storage disks n the SAN or as an isolated silo. For example, it is perfectly acceptable to aggragte to Vblock 1’s to provide capacity for 6000 VMs that can share common storage capacity… As long as storage capacity is added in conjunction with compute capacity to maintain balanced performance as published within the Vblock, the system does not require any additional validation .

Heh, you bet they want to sell you lots more so of course there is an answer for this. Once you have made the first purchase, you are likely to come back for more. Lets make it easy for the customer to do that.

So, Why are vBlocks so Large ?

A Vblock 1 is expected to support from 800 to 3000 VMs, and a VBlock 2 is expected to support 3000 to 6000 virtual machines. Since I started writing this post, a Vblock 0 has been announced that supports 300 to 800 VMs.

You might think that 800 is a lot of VMs. You might think that the price of a Vblock is too much. In which case, you aren’t someone who is going to buy it. If you can’t scratch together the several hundred thousand in single purchase order, you do’t understand the question. Today, many companies buy infrastructure as part of the project. If a project needs a server and a switch then that is funded. If a project needs a data centre, then a data centre is built. If a project needs fifty servers, then they MIGHT consider using VMware. Mostly we wait a few years and then have a big project to clear up the mess created by project funding of infrastructure.

Cisco and EMC don’t want to sell this product to small business. Cisco in particular wants to establish themselves in the marketplace as quickly as possible. Therefore selling to big companies, who are doing the “big cleanup project”, who are taking the time to evaluate the whole cost of ownership cycle, implementing with a full cycle approach is what Cisco wants. This is important.

Why ? Because Cisco wants to be able to produce white papers claiming the “huge cost reductions”, and “radical operations alignment” and “enabling technologies” etc etc. These white papers have real impact on the analysts and customers who figure that if they buy the product they will get those benefits. All these great stories, so loved by ‘journalists’ convince the middle sized market to buy Cisco servers.

What does EMC get ? EMC gets to move into the mid-sized market right alongside Cisco. EMC has been targeting the high end of the market, and they need new markets. A move down into the mid-sized market must not damage the high end products and branding (since this could affect profits), and attaching to a “differentiated” product will keep the premium marketing message intact.

EtherealMind View

Basically, I view the Acadia partnership as an upmarket fancy marketing campaign with extensive tie-ins. It’s “dressed up with a little black dress and killer set of heels” and well funded to boot. This type of thing normally makes me distrustful as many of these initiatives have turned out to be one night stands with an uncomfortable and unhappy morning after.

On the other hand, both Cisco and EMC have attached their corporate goodwill to this program in a major way. If Acadia fails, both companies will suffer significant image loss. It’s not marriage, but they are definitely living together.

The Challenge to the Status Quo

One of the most exciting (to my mind) aspects of the Vblock concept, is the potential to change the purchasing cycle of IT Projects. Many companies fund new purchases from projects only. This tends to create an inherently failed infrastructure buildout where each project buys what it needs. Project “cost controls” mean that infrastructure is rarely purchased to outside the project requirements. That is, buying additional disk drives or edge switches is easy, but buying additional arrays or core switches is almost impossible.

A Vblock could represent a “once a year” purchase of server infrastructure. Much easier than endlessly integrating, and reintegrating a hodge podge of servers, memory, disk drives and accessories into some sort of complete system. Compare this with the HP C-Class chassis concept which requires endless upgrades to scale into new and more useful configurations.

Most importantly, once engineers are freed from mundane tasks of installing memory and disk drives, they can move to focussing on the management platforms and dramatically enhancing the business value of computing. Tasks such as automating software and OS deployment, automated failure responses, performance analysis and

Cisco needs to buy EMC

Ultimately I remain convinced that Cisco must and will buy EMC to compete with HP and IBM. The Acadia joint venture looks a lot like a trial or temporary position while the market reaction is gauged. EMC has a marcap of USD$34 billion and revenue of USD$14 billion while Cisco has marcap of USD$154 billion on revenue of USD$35.5 billing. Cisco appears capable of acquiring EMC and is believed to have sufficient cash reserves to make a substantial cash rich offer. EMC probably has pretentions to be a lot bigger and don’t want to be bought right now. EMC egos are well known for their ‘capacity’ and they work hard at that. Combine that with a Wall Street that is anti-acquisition at the moment, and Cisco can’t make a move right now.

Public Clouds are not ready for the Enterprise

Public Clouds are fine for people that are not conducting serious business today. Dot Com startups, marketing pushes, publicity campaigns and other low vitality requirements could be considered for cloud infrastructure due to their trivial nature, but serious business applications are unlikely to move into the cloud with the current level of capability.

However, private clouds are practical today. To me, Vblock looks like an early mover in the Private Cloud space for IaaS. The option for a corporate IT department to build a three rack system that hosts between 300 to 700 servers is an exciting development. If I can reduce the amount of time my operations teams spend doing trivial and repetitive tasks and move them into systems automation on the management platforms, then we are moving to better place.

Technology Acceptance

There are no technology issues in this stack. In general, people perceive that Cisco and EMC are market leaders in their respective spaces, and the corporately the two companies fit well together. Unlike other stacks, there doesn’t appear to be a product that is less than excellent. In this sense, few people will dismiss the Acadia solution on technology grounds.


Convincing IT Management to take on the change put forward by Cisco / EMC is going to require a lot of marketing and sales. And that’s exactly what Acadia is all about. The technology takes care of itself here, Acadia is just marketing exercise, but a good one.

  • Hey Greg,

    Good article. I'd be interested to know how Centera fits into V-Block. You briefly mentioned it in the beginning. Thanks.
