The Effects of Virtualization on Data Center Power and Cooling

Although virtualization technologies have been a great help to data center managers looking to reclaim power in an overburdened environment, virtualization can also create problems. As IT organizations complete their server virtualization initiatives and as their virtualization management skills mature, use of the physical server power management features and dynamic workload shifting capabilities will increase. This, coupled with increased adoption of server hosted desktop virtualization, will create new opportunities for improving the efficiency of data center power and cooling systems, as well as new challenges for keeping up with increasing demand.

Citrix and VMware face-off over client hypervisors

Last month at VMworld, VMware took a major step forward in its desktop virtualization vision with the introduction of View 4.5. On hand for the launch was Gartner Research Vice President Chris Wolf who confirmed that View 4.5’s improved scalability coupled with the addition of role-based delegated administration change auditing features and the ability to support Windows 7 meant that View 4.5 joined Citrix XenDesktop 4.0 in fulfilling Gartner’s requirements for an enterprise-class server hosted virtual desktop platform. Although, View 4.5 is more notable for a feature that is not required to obtain Gartner’s blessing.

View 4.5 Availability and Enhancements

Anticipating the formal announcement was a widely leaked report that View 4.5 would ship without Virtual Profiles, the user profile management solution that VMware OEMed from RTO Software in fall 2009. VMware finally confirmed that the leak was correct on the first day of VMworld 2010, but even then held back from announcing its interim solution until after the formal product launch. Then rather than simply offer View customers a copy of Virtual Profiles as a standalone product, VMware chose instead to partner with Liquidware Labs to enable them to offer Liquidware Labs’ ProfileUnity to View customers at a substantial discount. While VMware’s position is that Virtual Profiles will ship with View 4.5 at some point in the future, the decision to offer ProfileUnity instead did nothing to address the concerns of potential customers, especially those who might finish up paying twice for a profile management system. The only good news for View customers is that ProfileUnity’s agent-less and database-less architecture should make the future migration to Virtual Profiles a simple matter when the time comes to move.
