Virtual Desktop Infrastructure (VDI) products such as Citrix® XenDesktop® can provide organizations with significant cost savings, streamlined implementation and ease of desktop management. In order to achieve these VDI benefits and to ensure optimal user experience, storage infrastructure design and sizing considerations need to be addressed carefully.

The goal of this paper is to present the results of a series of storage I/O (input/output) performance tests conducted by Dell Labs and provide storage sizing guidance and best practices based on those results for a Citrix XenDesktop-based VDI solution.
