Stratus ftServer Systems With vSphere 5.1 for Critical Virtual Workloads
Since 2004, agencies have run VMware software on ftServer systems to prevent downtime instead of recovering from failure after the damage is done. For VMware users with critical Tier 1 applications that demand zero downtime and zero data loss, Stratus Technologies, Inc. has announced that vSphere 5.1 virtualization software is now available on its newest line of Stratus ftServer fault-tolerant systems. Stratus is a global provider of products and services focused on protecting critical applications from system downtime.
Launched in September 2012, the sixth-generation ftServer 2700, 4700 and 6400 models are specifically engineered for superior availability and to be simple to deploy, manage and maintain. ftServer systems integrate into existing infrastructures as easily as any x86 server, yet they provide uptime of at least 99.999% (equivalent to 5.26 minutes of downtime annually) for the server and the vSphere hypervisor with little to no staff oversight. Stratus backs up its claim with a $50,000 zero-downtime guarantee for newly purchased systems that covers both server and hypervisor for six months from the time of installation.
The ftServer architecture enables the server to ride through hardware faults unaffected, unlike vSphere HA software, which does nothing to protect the underlying server from downtime. In the event of failure with HA software alone, VMs will fail over to another host where applications are restarted. Migrating and restarting all the applications can take many minutes, depending on the number and complexity of the applications. During this failover/restart period, applications are unavailable and data not written to disk is lost, as is the case with all cluster-like configurations. An ordinary server can also be a single point of failure for critical management operations such as those performed by vCenter Server.
