Last week at VMworld we demonstrated our everRun VM Lockstep Option for Citrix XenServer 5. Despite the decrease in foot traffic on the show floor, the turnout was much higher than expected. High airline prices (or possibly just the Vegas night life :)) may have kept some people away, but we presume our high turnout was a result of the increase in innovative sessions and seminars. For those of you who weren’t able to attend or were there but didn’t get an up-close look at our everRun VM Lockstep demo, Michael Keen (a.k.a. C1tr1xguru) shot this video of our CTO, Jerry Melnick, giving an in-depth demonstration of system-level fault tolerance for virtual environments. Thanks for stopping by Michael. Our demonstration gave visitors an inside look at all three levels of availability: 1. XenServer HA: Level One: Failover High Availability standard with XenServer 5 Ente... (more)

Gartner’s Top 10 Strategic Technologies for 2009

A couple of weeks ago Gartner released their “Top 10 Strategic Technologies for 2009.” Each technology is defined as, “one with the potential for significant impact on the enterprise in the next three years.” The technologies listed have been available for quite some time – many of which were present on last year’s list – but one that continues to move up in rank is virtualization. Considering the state of the economy, we anticipate this to be an area that will continue to flourish over the next 12-24 months as virtualization technology becomes feasible for businesses of all siz...

Understanding XenServer HA

Following the XenServer HA announcement, we’ve been approached with questions like “How exactly does XenServer HA work?” and “How does XenServer HA and everRun VM work together.” Rather than respond ourselves we thought it would be best to point to a few fellow bloggers who have already answered these questions. First, here’s a good post written by Anil Madhavapeddy at Citrix discussing how the overall architecture of XenServer HA works. Second, Scott Lowe has put together a great summary of why Citrix and Marathon worked together to develop XenServer HA. If you want more detai... (more)

How Virtualization is Changing the Way We Think About Availability

Analyst firm The 451 Group has just released some very interesting findings about virtualization and availability in a recent report by Chief Analyst John Abbott. Some of the key take-aways include: • Virtual infrastructure can form the basis of fully automated availability processes. Availability becomes a default property of the virtual machine. • ‘Dial up’ levels of availability can be implemented, depending on the requirements of specific applications or departments. • If a system restore is required after a disaster, it’s usually much easier and much quicker to restore a virt...
