In the server space, one of the biggest shifts was the form factor of the servers: From tower to rack-mount to blades. But what makes a blade server anyway? Let’s consider this for a moment, as we watch another shift in progress.
I talk to dozens of companies every week, and every one says the same thing: â€œOur product is compatible with VMware!â€ But not everyone’s definition of â€œcompatibleâ€ is the same, and some are not compatible with the requirements of production data centers. Therefore, I present to you my spectrum of compatibility for VMware.
EMC VFCache (nÃ©e Project Lightning) is a fairly simple offering: A server-based PCIe flash card that acts as a read cache with no integration with storage arrays or hypervisors. But EMC’s entrance into the host-based flash storage market is a powerful demonstration of the wave of disruption caused by flash-based storage and high-performance computing.
I was looking through some email today and saw a newsletter from ZDNet at the top of my inbox. Â Normally these don’t get my immediate attention, but for some reason, today… it did. Â There was a post from Mary Jo Foley (linked below) looking at the upcoming file system in Windows Server 8, ReFS. I […]
This is a tool I've been using almost daily in my current project and for the past few months. Now It's finally been released to the public! The tool has been created by Chuck Hirtsius – one of the EUC Specialist's within VMware. The release you see here today is the first release of the […]
The new Nimbus Data E-Class comes just at the right moment, with 500 TB of capacity, a fully redundant â€œdual activeâ€ controller architecture, massive performance (even InfiniBand), and complete feature set (once VAAI is released).
Moving cold virtual machine images from system to system, or even across great distances, is one of the main selling points of server virtualization. But it becomes much more difficult to manage movement of virtual machines that are still running, especially outside cluster or across WAN links. When talking about virtual machine mobility, it is important to consider what is being moved, the state it is in, and where it is going.
HP stumbled mightily in 2011, and it had nothing to do with product or people. Even sales remained strong, though the PC business is changing. HP’s mighty stumble was a crisis of confidence due to a chain of shenanigans at the very top. This culminated with the short reign of LÃ©o Apotheker, leaving HP to reassure the market of its strategy.
For a massive IT company, Dell sure doesn’t get the kind of respect given their competitors. Time and again, I’ll hear the sneers about Dell being little more than a â€œbox shifterâ€ who doesn’t â€œgetâ€ real enterprise IT needs. After a series of acquisitions in storage and networking, Dell is trying to stake a claim as a serious competitor to HP, IBM, Oracle, and the like. But why should anyone take Dell seriously, especially in enterprise storage?
For the past few months I have been spending a lot of time looking at the performance of Large VDI environments, where the problems lay and where performance can be improved. When designing VDI environments, a couple of things that you should consider are the .vswp file and the GuestOS paging file. In this article […]
