I have not read into it heavily, but it seems to have two components. The hardware failover appears to be far more intricate than just Vmotion.
· Lockstep technology uses replicated, fault-tolerant hardware components that process the same instructions at the same time. In the event of a component malfunction, the redundant component provides an active spare that continues normal operation and averts system downtime. The system also eliminates transient hardware errors that could cause software failures if left unchecked. Hardware logic, in the form of Stratus ASICs, provides the core error detection, fault isolation, and synchronization logic for the lockstep architecture. While other servers may offer duplicated power supplies, fans, and disk drives, only Stratus provides protection for core system components including motherboards, processors, memory, I/O buses, and I/O adapters. · Our failsafe software works in concert with lockstep technology to prevent many software errors. Unlike typical servers or clusters, ftServer hardware and software handles such errors transparently, shielding the operating system, middleware, and application software. Even in-memory data is constantly protected and maintained. Management and diagnostic features also capture, analyze, and notify Stratus of software issues. This allows support personnel to take a proactive approach to correcting software problems before they recur. Our hardened device drivers also add considerable reliability to the Windows environment on ftServer systems.

I run a virtual Citrix farm and obviously am very interested in anything that increases the reliance of my servers...but I already have Virtual Center, VMotion, HA and all the other bells and whistles that go with ut 2009/2/11 Doige, Clayton <[email protected]> Tell them to look at EverRun VM from Marathon. www.marathontechnologies.com awesome solution, sits on top of the citrix virtual server platform (Xen Server) so you can use it to protect multiple virtual servers for the cost of one server pair license (the license includes the cost of two copies of Xen Server Enterprise) so the bund comes in under £4K british plus the hardware, which just needs to be Hardware Virtualisation Assist enabled.

Medical client looking to move their servers to this. Recommended by the app vendor. http://www.stratus.com/products/ftserver/index.htm Thanks, just looking for feedback.
