DataCore's SANsymphony™ and SANmelody™ products have been certified on Citrix’s newest XenServer 5 release as virtual SAN appliances, as well as on both standard servers and blades. With XenServer 5, Citrix has optimized Citrix XenApp performance on XenServer virtual machines. According to Citrix, this enables XenApp workloads to be virtualized with as little as 7% overhead and as many as 73% more users than XenApp workloads virtualized with competing products. Citrix XenApp (formerly Citrix Presentation Server) is used by more than 100 million users and 99% of the Fortune Global 500.
