"Sanbolic's Melio VDI delivered the high availability, ease of maintenance and seamless scale-out AXPO required for its Citrix XenApp and XenDesktop environments. By managing files and application data independent of the underlying storage medium, Melio now enables its storage volumes to be easily migrated across hardware and sites to meet varying service levels and availability requirements," said Eva Helen, President, COO and Co-Founder, Sanbolic. "Each AXPO data center can now use a single shared copy of the images, thereby dramatically increasing utilization and simplifying management. Moreover, Melio's embedded replication capability ensures the most recent copies of all vDisks are synchronized between both data centers in the event of a site-wide failure." She continued, "With Melio VDI's scale-out capabilities, AXPO can now add additional PVS servers and storage resources on the fly, without requiring a maintenance window. This allows AXPO to maintain optimal user experience as they continue to support a growing number of third-party customers."Technical Specifics of AXPO's Sanbolic Melio VDI Solution AXPO now uses Sanbolic's Melio VDI software to enable multiple PVS servers within each datacenter to share concurrent access to a single volume that contains all the XenApp server image files (vDisks) or XenDesktop images. Melio VDI provides active/active storage access to multiple PVS servers, allowing AXPO to store hundreds of XenApp image files in two volumes: one volume accessed by the PVS servers in the first data center and the second volume accessed by the PVS servers in the second data center. This configuration greatly simplifies vDisk management and maintenance. It also provides continuous vDisk availability in the event of PVS server failures. Melio VDI now also supports the dynamic addition of PVS servers and on-demand volume expansion, while the Citrix environment remains on-line. This enables seamless scale-out of the infrastructure to support thousands of desktops, maintaining a consistent user experience even during morning boot storms.
