Early adopters of virtual desktop infrastructures (VDIs) that relied on hard disk drives (HDDs) were disappointed by the lack of performance of the solution:
- Response times suffered because of the unique nature of the I/O demand that VDI places upon the storage subsystem.
- Scaling the infrastructure meant adding expensive, yet inefficient, tier-one storage to handle the additional I/Os, even if capacity were not an issue.
- Management of the infrastructure sprawl became difficult.
- Unexpected costs diminished promised ROI.
VDI environments help maximize productivity by helping employees access applications regardless of physical location or connection device. However, the speed of the storage can limit the speed of the entire system. The IBM FlashSystem in a Virtual Desktop Environment Solution Guide explains how IBM FlashSystem products can accelerate common VDI applications, including the IBM SmartCloud Desktop infrastructure.
FlashSystem storage is built for one purpose: making storage faster. When you run your VDI with FlashSystem storage, there are no spinning disks. FlashSystem products have a hardware-only datapath and much lower response time (latency) than solid-state drive (SDD) devices and many other forms of flash storage. You can move your most I/O intensive applications to FlashSystem storage to improve the performance of the entire environment.
