The following paper by Citrix CTP, Microsoft MVP Shawn Bass discusses workload improvements with Citrix XenApp and RDS when using Atlantis Computing’s new ILILO for XenApp solution.
Deploying Citrix XenApp and RDS workloads behind Atlantis ILIO can reduce storage requirements, improve provisioning and boot time and improve scalability when I/O is a limiting factor for scale. When I/O is not a limiting factor, there are still storage savings, faster provisioning and boot time, but scale is reduced slightly in a single server scenario.
When implementing Citrix XenApp and RDS servers in a virtualized environment, a commonly overlooked area is storage performance. While many people are very aware of the storage impact of VDI, few people give enough thought to the impact of XenApp performance from the shared storage tier. Often customers find that virtualizing their RDS/XenApp servers result in less scalability and performance compared to when the servers were on physical hardware. Sometimes this can be attributed to lack of performance on the shared storage platform.
