We had some studio time available recently and took the opportunity to capture the alpha version of Citrix XenClient as you've never seen it...in HD. We thought it fitting given our ongoing dedication to HDX technology in both the Citrix XenClient and Citrix XenDesktop platforms.

Before we get to the videos, let me take just a few moments to review some basics about Citrix XenClient.

XenClient is a bare-metal local desktop virtualization platform based on the same technology that goes into Citrix XenServer including the open-source Xen hypervisor. Translation - XenClient allows you to run multiple virtual desktops locally on the same device, in complete isolation with kickass performance and graphics. Much of the credit for the performance can be given to the hardware-assisted virtualization in the Xen hypervisor combined with the work that Intel has done to give you the same great performance and user experience on your virtual desktops as you would expect on a physical laptop (or desktop).

Watch the XenClient Overview(1 minute)

There are many benefits to bare-metal desktop virtualization. One of the more obvious benefits is performance. We could go into all the ways a type-1 harware assisted hypervisor does that, but thought it might be easier to just show it.

Watch Citrix XenClient HDX Performance (2:30 minutes)

Pretty cool huh? Stay tuned for parts 2 and 3 where we will show off the use cases for XenClient as well as its ability to keep your computing environment secure.

Watch all four videos in the XenClient series or visit XenClient Central for more information on XenClient.

One of the most common requests from XenServer customers is for a web interface, so that they can manage their VMs from a browser. I'm pleased to say that I've found one!

It's called xvp, and has been developed by Colin Dean at Durham University in the UK. There are four components:

  • xvpweb: A web front end for XenServer, running on Apache/PHP.
  • xvpviewer: A Java applet for accessing XenServer consoles (used by xvpweb, of course).
  • xvp: A server-side proxy for XenServer consoles, so that you can use ordinary VNC clients.
  • xvpdiscover: A tool that queries a XenServer pool, and writes the appropriate configuration files for xvp and xvpweb.


The whole thing is open source (GPL v2). It uses libxenserver, XML-RPC for PHP, and parts of TightVNC.

It's been in development since May 2009, and is now on version 1.2.4.

T-Mobile and Microsoft announced that a Microsoft subsidiary had suffered a "data-service disruption" that wiped out all Sidekick users' contacts, calendar entries, to-do lists, and photos. In the joint statement, Microsoft/Danger and T-Mobile said its teams were working "around the clock in hopes of discovering some way to recover this information." However, it noted that the likelihood of doing so "is extremely low." - From NewsFactor.com (Oct 12, 2009)

Google Search and Google News performance slowed to a crawl, while an outage seemed to spread from Gmail to Google Maps and Google Reader. From ComputerWorld (May 4, 2009)

It's hard to believe in this day and age that we should hear of data recovery being an issue, isn't it?  Even the government has explicit input into this worrisome problem.  Yet in the past six months we've seen two major Cloud Computing corporate faux pas.  More correctly, here we are talking about Business Continuity or drilling down one level, Workforce Continuity

One of my colleagues, who shall remain nameless, was aghast with these news releases and asked if it would negatively affect the push we are seeing in industry toward consumption based delivery of IT services.  Specifically, if Citrix technology was associated with one such disaster as a part of the Citrix Service Provider program, would we end up with a "black eye" and thus a negative brand implication?

Ironically, when I was working on our CSP TCO/ROI calculator, the question came up about Disaster Recovery and whether or not service providers offer it as a part of their subscription/hosting business.

The next logical question is 'Do service providers also provide some form of disaster recovery for themselves?'  It's one thing to back up data for the end customer, but what if the service providers' whole farm goes down?  Well... this is really a great question, but as we've seen from the recent press, it may be a matter of big fish vs. small fish.  For example, smaller hosting/service providers can and do back up their data using larger enterprises such as Amazon's S3. Why?  The costs are relatively low and the processes relatively easy to use. 

Also, because storage arrays are relatively inexpensive and technologies such automated failover are available, many smaller scale service providers opt to use their own backup and recovery systems on premise.

So one might ask, what about the big guys (Google, Amazon, Microsoft)?  Who provides their data recovery systems?  Well... based on the performance recorded in the press over the past few months, that appears to be a very good question.  There are speculations that because large Cloud Compute companies use (very) low cost equipment (servers and storage arrays) that duplicating real-time data for instantaneous recovery is just a part of their operations.  But is it really?

One of the challenges with scale is that you have to have enough compute power and storage to not only service the masses, but to provide continuity (and backup) in the event of a catastrophic failure.  Will negative press such as that from Google and Microsoft's "Danger" (what a name for a DR company!) keep businesses from using service providers for their mission critical data?  Anecdotally I've got to say no... at least at the SMB level because the data shows an increase in off premise IT services.  But maybe Google and Microsoft need to take a closer look at how they handle these types of services, especially for the large enterprises.

I've got a question for you. When was the last time you actually tested your Business Continuity system?  I mean, really tested a failure to see if your processes meet your users' expectations?  Don't get caught in the news answering the question like these guys did!

My friends in HP Solutions Engineering tell me that historically capacity planning for server deployments was not a trivial task given the range of variables to consider, not to mention the time and therefore the expense required to do it right. And now add virtualization variables to the mix and capacity planning tasks can be even more challenging. YET, effective capacity testing can supply a big payoff by ensuring that your virtualized environment can be the best it can be, and that you gain all the cost savings and flexibility improvement benefits promised by virtualization. See here for a recent HP post on capacity planning in virtualized environments.

Of course it is not surprising that there are a number of innovative tools out there to assist in these efforts for Citrix environments, including HP LoadRunner, a popular load testing tool used for planning XenApp deployments, and the Citrix EdgeSight for Load Testing server sizing and application performance testing solution.

We have a excellent new technical resource for capacity planning with ESLT - the recently released "Using EdgeSight for Load Testing ..." white paper developed by HP and Citrix describes how to implement ESLT tools and scripts to characterize scalability for various HP ProLiant servers with XenServer and XenApp. This paper is a great addition to the ever expanding set of technical papers published on XenApp and XenServer - visit here to browse the entire library.

Don't forget to register for the Citrix Live! Virtual Event, Secrets, Lies and VDI happening Oct 20th and visit the HP sessions and exhibits! Enjoy.
