Data Center Virtualization

Data Center Virtualization covers virtualizing servers, networks, and storage delivering server consolidation, CAPEX savings, IT agility, and improved management. Major areas of focus include the tradeoffs between various virtualization platforms (VMware vSphere, Microsoft Hyper-V and Red Hat KVM), the evolution of hypervisors into data center management platforms, (Read More)

VMware’s Software Defined Data Center strategy, and how the SDDC is spurring innovation in storage, networking and server hardware. Covered vendors indlude VMware, Microsoft, Red Hat, CloudPhysics, Hotlink, Tintri, and VMTurbo.

Cisco Nexus 1000v: Free unless you want Security

VirtualizationSecurityWhile not particularly new news, the next version of the Cisco Nexus 1000v will be free, unless you want the security features. This is an interesting shift from Cisco with respect to VMware vCloud Director, the Nicira purchase, furthering UCS, and Cisco within non-UCS data centers. However, given other announcements, with respect to OpenStack, perhaps this is more a play to level the playing field between cloud architectures? But what I find most interesting, is that the changes to the Nexus 1000v also align with the changes we see in the vCloud Suites from VMware.

How Will VMware’s Distributed Storage Change their Relationships?

DataCenterVirtualizationAt VMworld 2012, VMware presented a Tech Preview of one of their latest ideas, which they termed “Distributed Storage”. So what exactly is this new technology? It is basically locally attached storage.

How is Distributed Storage new?

We know that VMware has allowed the use of local storage since inception; however, access to that storage was limited to the local host only, so it was only utilised for guests that were node-based, e.g., vShield appliances. To delve a little deeper you could use the analogy of a VSA (Virtual Storage Appliance), but unlike the VSA, which is a fully functioning virtual machine, this technology is actually part of the hypervisor.

vCloud Suite: Why is VMware Turning its Back on VM-based Licensing?

CloudComputingAt VMworld VMware announced the release of the vCloud Suite of products. This new suite of packages, depending on the level purchased, bundles together several individual products into a single purchase point. See the table later for details of which package includes which product.

However, to me the most interesting point was the fact that this suite is purchased per processor, not per VM. This, coupled with VMware’s announcement of the death of vRAM, means that you can in theory now get a lot more bang per buck spent with no artificial limits set on usage. Continue reading vCloud Suite: Why is VMware Turning its Back on VM-based Licensing?

Licensing your Private Cloud

DataCenterVirtualizationBoth Microsoft and VMware have revamped their product suites, and therefore their licensing, once more. As always, how you buy will dictate how you license. It has taken a bit of time for all the revamped information to percolate through to each corporate site and for all the issues to be addressed. As we did before, let us look at licensing. We will look first at the old model of Hyper-V vs VMware vSphere vs Citrix Xen vs RedHat KVM. Then, in a follow-on article, we will look at the new cloud suite models.

The Software Defined Data Center and VDI

DesktopVirtualizationIn this GigaOm article, Steve Herrod, the CTO of VMware, explained, “Software defined data centers are “generation-proof.” They collapse disparate systems into a singularity built atop commodity x86 processors and other gear. Software provides everything that is needed to adapt the data center to new situations and new applications, and to manage everything from storage to switches to security. Although VMware will always work with hardware partners, Herrod said, “If you’re a company building very specialized hardware … you’re probably not going to love this message.” Continue reading The Software Defined Data Center and VDI
