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. Continue reading Citrix and VMware face-off over client hypervisors

Sum of the Parts… Not equal to the Whole

Christofer Hoff (@Beaker) and I had a short discussion on twitter the other day about the VMware Cloud Director (vCD) security guidance. We both felt it was a bit lite and missed the point of Secure Multi Tenancy. However, I feel even more strongly that people will implement what is in the vCD Guidance, vBlock Security Guidance, and the vSphere Hardening Guidance, and in effect have a completely insecure cloud. These three guides look at the problem as if they were singular entities and not as a whole.

This realization tied to Chad Sakac’s recent discussion on the 9/22 VMware Communities podcast leads me to believe that ‘good enough’ is no longer ‘good enough’ from a security perspective.  Chad discussed that there need only be the vCloud Director administrator and the vSphere administrator to do the daily heavy lifting. That there would no longer be the need for a security, network, storage, and system specific administrators. In other words, OPEX savings. Continue reading Sum of the Parts… Not equal to the Whole

Acadia and Its Place in the World

I can remember, in what seems like a really long time ago, about the creation of a new company that will support the coalition of VMware, Cisco and EMC’s vBlock product: Acadia.  I had really long forgotten about the new company that was going to be formed when EMC really started their hiring blitz and campaign to get all the well known talent that EMC could get their hand on.  That had been the news and buzz in the industry, as well as a nonstop twitter topic speculation about who was going to be the next person  to enroll in Chad’s Army as a vSpecialist.  It really appeared that the EMC crew was going to be in the best position to support and sell vBlock technology.

What got my attention about Acadia again was Chad Sakac blog post about “More than 200 open positions at EMC, EMC partners and VCE.” In case you had forgotten about them also Acadia, it is a joint venture, founded by Cisco and EMC with capital investments from VMware and Intel. It is the combination of these companies that make up the VCE Coalition. The VCE is VMware for the virtualization, Cisco for the networking and server hardware and EMC for the storage.  All of this to be able to present a faster and safer transition to a next generation data center environment.

VMware, Novell and the Management Stack

Most of the attention on the rumors that VMware may be acquiring parts of Novell have focused upon VMware acquiring the Novell SUSE Linux assets. This would obviously result in VMware finally having an complete operating system of its own (unless you consider vSphere as an OS – which it obviously is at least in part).
