Heterogeneous Virtualization Trends at Gartner Data Center
Posted by Chris in Citrix, Cloud, Microsoft, Oracle, Server Virtualization, VMware, Virtualization, redhat on December 11th, 2012
Heterogeneous virtualization has been a hot topic among clients and last week at the Gartner Data Center conference in Las Vegas I presented a session on the subject. During the session, I polled the audience on their heterogeneous virtualization plans. Fifty participants responded to each polling question.
The first question I asked was about the current hypervisors that were deployed (note that the values are the number of respondents and not a percentage).
As you can see, most participants used VMware vSphere as expected, and there was a good mix of Hyper-V, XenServer, and some RHEV and Oracle VM.
It’s (Read more...)
Desktop Virtualization Trends at Gartner Data Center
At the Gartner Data Center conference in Las Vegas last week I asked several polling questions regarding desktop virtualization adoption plans and trends, and thought that they were worth sharing. Note that the poll was taken in my session on “Desktop Virtualization: Tales from the Trenches,” so the audience was already at least considering the technology.
The first question I asked was regarding business drivers.
As you can see above, the majority of respondents wanted to use the technology to reduce TCO, while giving users a “Follow-me desktop” was a close second. We have multiple clients that have been able (Read more...)
VMworld 2011: If Amazon is the Benchmark…
In a recent Gartner field search study, two early internal IaaS cloud adopters noted that if Amazon was the benchmark by which they are measured in terms of cost, then they had to make tough decisions regarding best-of-breed vs. good enough. In particular, the two clients cited whether deploying a third party virtual switch (i.e., Cisco Nexus 1000V) was absolutely necessary, especially if the cost made the internal cloud less competitive with Amazon. These organizations weren’t doing apple-to-oranges comparisons either. They came up with a per-VM cost broken down by both infrastructure and management/operations software. The cost of operational software (Read more...)
VMworld 2011: Dancing on Citrix’s Doorstep?
Posted by Chris in Citrix, Client Virtualization, VMware, vmworld on September 6th, 2011
VMware recorded a pretty humorous video that was unveiled at this week’s VMworld North America conference. A few minutes into the music video, VMware folks are literally shown dancing on Citrix’s doorstep (outside the Citrix office in Santa Clara). While this could be taken as a simple competitive prank, multiple conversations I’ve had with VMware’s end user computing team led me to believe that the dance was more of a metaphor for VMware’s confidence in their product portfolio. At the Gartner Catalyst North America 2011 conference, VMware announced that View 5.0’s PCoIP protocol enhancements would reduce bandwidth by up to (Read more...)
Catalyst 2011 User-Centric Computing Track Speaker Line-up
Posted by Chris in Citrix, Client Virtualization, VMware, Virtualization, quest on May 10th, 2011
The speaker line-up for Catalyst 2011’s user-centric computing track has been finalized and I wanted to take a moment to share it with you. A prominent CTO has called Catalyst “the most intellectual conference in all of IT,” and if you haven’t attended Catalyst before, there are plenty of great reasons to get there this year. We have extensive coverage of server- and client-virtualization, cloud computing,and many other hot topics. The rundown of sessions in the user-centric computing track is listed below. I hope to see you there!

Oracle Broadens x86 Virtualization Support, but Work Remains
Posted by Chris in Citrix, Cloud, Microsoft, Oracle, Server Virtualization, VMware, Virtualization, amazon on November 10th, 2010
Today EMC’s Chad Sakac blogged about a significant update to Oracle’s support policy for VMware ESX environments – Oracle no longer explicitly excludes Oracle RAC from being virtualized. It should also be noted that Oracle’s support is limited to “issues that either are known to occur on the native OS, or can be demonstrated not to be as a result of running on VMware.” In other words, if it’s not a known bug, customers may be asked to reproduce problems on the bare metal.
Like Chad, this is an issue I have blogged about repeatedly over the last couple of (Read more...)
PCoIP vs. ICA/HDX: A Simple Experiment
Posted by Chris in Citrix, Client Virtualization, VMware, vmworld on October 21st, 2010
Last week I traveled through various parts of Europe, while stopping for two days in Copenhagen for VMworld Europe. With eight days of travel, I thought it would be a good opportunity to test the feasibility of working from a server-hosted virtual desktop while traveling abroad. I run both Citrix XenDesktop 4.0 SP1 and VMware View 4.5 in my office lab in New Jersey. Accessing virtual desktops over the local area network using my Wyse Zero clients offers nothing short of an outstanding experience. I connect to my XenDesktop systems using the Wyse Xenith and connect to View using the (Read more...)
PCoIP vs. ICA/HDX: AT&T 3G from Newark Airport
Posted by Chris in Citrix, Client Virtualization, VMware on October 21st, 2010
This post is the second in my series “PCoIP vs. ICA/HDX: A Simple Experiment.”
The first PCoIP vs. ICA/HDX WAN performance test in my experiment began at Newark airport. I’m not one to spend more time than absolutely necessary in an airport, but I still gave myself plenty of extra time to conduct and record my tests.
The AT&T 3G connection between my laptop and home office lab offered great bandwidth (1.08 Mbps), but not-so-great latency (122 ms). Both PCoIP and ICA/HDX responded well in this environment. I had no problems with Microsoft Word, navigating the Start menu, (Read more...)
PCoIP vs. ICA/HDX: Munich, Germany to New Jersey, USA
Posted by Chris in Citrix, Client Virtualization, VMware on October 21st, 2010
This post is the third in my series “PCoIP vs. ICA/HDX: A Simple Experiment.”
After arriving at my hotel in Munich, I was ready to again compare PCoIP and ICA/HDX performance. When I connected to my lab, I was surprised that latency from Germany was actually less than with my AT&T 3G connection in the US. While I measured latency at 122 ms when connecting using my AT&T 3G card, latency from my hotel in Munich measured only 106 ms. As expected, bandwidth wasn’t as good as with my AT&T 3G connection. I measured 480 Kbps from the (Read more...)
PCoIP vs. ICA/HDX: Gavle, Sweden to New Jersey, USA
Posted by Chris in Citrix, Client Virtualization, VMware on October 21st, 2010
This post is the fourth in my series “PCoIP vs. ICA/HDX: A Simple Experiment.”
Last Wednesday I flew from Copenhagen to Stockholm, and then drove with my Gartner colleagues to a hotel in Gavle, Sweden, which was close to where we would meet a client the next day. I didn’t have much time to work with my virtual desktops while at VMworld Europe; that was mainly due to the fact that Internet connectivity was not working at my hotel.
Last Tuesday I used my VMware View client while listening to the conference keynote. During the keynote, I used (Read more...)
