Midsize (Less than 10 Terabytes) shared storage requirement for Citrix XenServer and Citrix XenApp virtual environment.
You are eager to take advantage of non-disruptive live migrations and VM auto-failover between physical servers, but your direct-attached storage cannot be shared. You have also determined that multiple VMs on the same physical server are generating far more disk I/Os and throughput than its storage equipment can handle. The cost to implement SAN approaches proposed by others exceeds your budget.
Configure DataCore SANsymphony™-V storage virtualization software on a pair of network servers that will be repurposed during the server virtualization project. These universal storage controllers form a centrally-managed, virtual storage pool by drawing disk space from their internal drives as well as any arrays externally attached to them. Serve shared storage for high-availability using the built-in synchronous mirroring feature. The software will use the CPUs and memory on the DataCore storage controllers as high-speed cache to handle the I/Os and throughput placed on the SAN by aggregated VMs.
