VDI implementations are characterized by write intensive random I/O patterns. Vasts amount of expensive high performance storage is typically deployed to properly sustain a sizable VDI deployment. As a result the cost per virtual desktop instance is often prohibitively high - the storage costs being one of the main obstacles to the wider VDI acceptance. The BOF session will cover various software approaches to drastically reduce the size and cost of storage while maintaining and even improving performance of scalable VDI implementations.
