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.
Virtual Storage
“Our Storage Array Is Compatible with VMware…” Says Who?
I talk to dozens of companies every week, and every one says the same thing: “Our product is compatible with VMware!†But not everyone’s definition of “compatible†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 (aka “Project Lightning”) Is One Small Step, But an Important One
EMC VFCache (née 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.
Nimbus E-Class: The First Big, Redundant, All-Flash Enterprise Array
The new Nimbus Data E-Class comes just at the right moment, with 500 TB of capacity, a fully redundant “dual active†controller architecture, massive performance (even InfiniBand), and complete feature set (once VAAI is released).
Virtual Machine Mobility: Of What, and to Where and in What State?
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.
Why Should Anyone Take Dell Seriously in Enterprise Storage?
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 “box shifter†who doesn’t “get†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?
Eight Unresolved Questions About FCoE
What elements remain unresolved to make FCoE truly world-class? What should the vendors be prioritizing?
Microsoft Adds Data Deduplication to NTFS in Windows 8
The next version of Microsoft Windows Server includes integrated data deduplication technology. Microsoft is positioning this as a boon for server virtualization and claims it has very little performance impact. But how exactly does Microsoft’s de-duplication technology work?
The Terrifying True Story Of Virtual Machine Mobility
Virtualization of server, network, and storage services illuminates the link between physical resources and functional applications. A running virtual machine can instantly move from one server, network adapter, HBA, or LUN to another. And when it happens, traditional components have no idea how to react.
Are You a Hypervisor Hugger or a Storage Stalwart?
The time has come to take sides on the core question of storage for virtual servers: Do you want storage intelligence to live in the hypervisor or the array? Most administrators are already lining up on one side or the other, unintentionally casting their vote while the rest flounder. But the storage industry must wake up and embrace the divide.
