iX Magazin Comparison: vSphere 4 FT vs. Citrix XenServer with everRun VM

Posted by: Michelle Liro

iX Magazin, a leading IT publication based in Germany, recently published an in-depth product comparison review of VMware’s vSphere 4 FT vs. Citrix XenServer with everRun VM in their September 2009 issue. In his article, “Fehlertolerante Systeme” or fault tolerant systems, reviewer Jörg Riether noted everRun’s ease of installation and intuitive setup process. Here’s a couple of additional highlights from the review:

“everRun has a very transparent way of handling the sudden total failure of a node without noticeable interruptions – this is true from the perspective of the administrator and from the viewpoint of the user working on the protected server. The Level 3 protected VM goes on running through each active application without any loss of performance. If the server is switched on again after being disconnected from the mains, everRun re-integrates it immediately and starts synchronization.

One of the fundamental advantages of everRun is demonstrated here: it doesn't require a data memory shared by both hosts. Marathon is able to replicate any virtual hard disks from one Xen host on the other and keep them synchronized. This eliminates the effort required for a SAN with synchronous mirroring and redundant paths as everRun itself includes the technology.”
