Virtual Desktop Infrastructure Storage (VDI Storage)

VDI Storage is a technology to decouple user desktops – OS, applications, data – from underlying hardware components like laptops or PCs. Virtualized desktops are hosted on a centralized infrastructure. Users can access the same desktop with a variety of end-point devices using a remote display protocol over a network. Enterprise grade storage is critical for VDI deployment success.

Why is storage a concern for VDI?

Consumer grade desktop storage found in laptops and PCs are inadequate for virtualized desktops running centrally in a data center. For a given capacity requirement, enterprise grade storage suitable for a data center environment costs an order of magnitude higher than the consumer grade desktop storage. Storage performance requirements are also higher in VDI than physical desktop environments.

What are the key requirements for storage in VDI?

Delivering high performance with consistently low latencies irrespective of user type (call center employee or CAD Designer), desktop life cycle (boot, logon, steady state, or logoff) and scale (50 or 50,000 concurrent desktops) is essential for a great end-user desktop experience, all the time. Stellar data reduction techniques are a must for the storage platform to be economically viable.

What are the benefits of storage designed for VDI?

Storage platform designed for VDI can deliver the promise of desktop virtualization. A scale-out, truly N-way active-active storage controller architecture coupled with inline, all-the time data reduction technologies can deliver high performance with consistently low latency at a significantly reduced capacity footprint, leading to best $/desktop and low TCO for organizations deploying VDI.
