Since its inception, virtualization has changed the information technology landscape in many ways. With all the good virtualization brings to the table, in some ways, virtualization has made things to easy. One example is the ease and speed that we are able to deploy new servers has virtual machines. No longer are we waiting on physical hardware to arrive for a new deployment. We can “clone” are golden image in a matter of minutes and be on our way.

Sorting Out "Desktop Virtualization"
Can you use Desktop Virtualization in your organization to improve IT delivery? Desktop Virtualization, as a concept, is straightforward – separate the desktop environment from the physical machine. This gives you benefits in terms of speed of delivery, how you can provide access to mobile and remote workers, how you can ensure security and compliance.
Host Only Supports 1 vCPU: Licensing?
I had a fun day resolving a licensing issue for a client. This one was a little different than I had seen in the past. The cluster is question is an eight node cluster running ESX 3.5. The error message that I received when trying to perform a vMotion was “Unable to migrate from HostA to HostB: Virtual machine has 2 virtual CPUs, but the host only supports 1. The number of virtual CPU’s may be limited by the guest OS selected for the virtual machine or by the licensing for the host.”
ZT Systems launch commercial ARM-based cloud server
If you are a hyperscale (such as for the Cloud) data center manager, one of your top concerns is always how to get the maximum amount of computing work done per Watt of power consumed. With that in concern at the forefront Cloud Providers like Google, Microsoft, and Facebook have strong incentives to explore new solutions to delivering compute cycles. Rumors coming out of Facebook suggest that it is looking to move away from its current X86 architecture platform in favor of servers based on ARM Holdings Cortex processor range. Porting an entire service to a new processor platform may not appear to be a sensible direction to take but porting to a new architecture is more a financial consideration than a technical one. If the cost per unit of performance justifies it , it is cheaper to pay a few programmers to rework the apps for a new architecture than it is to buy more servers.
Virtualization Backup: Agent or Agent-less?
Many times we virtualization experts push for backups without the agents as these backups tend to be in our opinion, cleaner and faster. But what if you could get the benefits of your existing backup tools (such as Tivoli) but gain the power and advantages of using all the possibilities within the virtual environment. For VMware vSphere this is possible using the Pancetera backup tools.
Cisco Virtual Desktop Experience
Considering the success of Cisco’s virtualization friendly UCS platform it should come as no surprise to hear that Cisco is intending to extend its data center virtualization footprint to include desktop virtualization as well. However as last week’s announcement of the Cisco Virtualization eXperience Infrastructure (VXI) shows Cisco does not expect a straight repeat of its server virtualization strategy to win the day. While Cisco’s plan to encourage mass adoption of desktop virtualization is based on the same Unified Computing System (UCS) that is behind Cisco’s current server virtualization strategy, it’s approach is distinctly different.
