Want High-Performance VDI? Go hyper-converged.

If you are considering migrating to a virtual desktop infrastructure but are afraid performance for your demanding users will suffer, a hyper-converged appliance might just be your answer. Most IT administrators are leery about moving their knowledge workers and powers users to a virtual environment because of historically poor performance associated with latency and bandwidth constraints. Recent advancements in Solid State Drives (SSDs), GPU technology, and more efficient network protocols coupled with improvements in the hypervisor’s file system have made moving these workloads to VDI not only possible but, in many cases, a better experience for the end user.VDI-image

Performance challenges in the past often centered around a bottleneck in accessing and moving data in the storage subsystem. The slowdowns came from multiple sources: access times on spinning disks cause delays in response times; Fibre channel and iSCSI links to the SAN introduce more latency; and, heavy network traffic loads slow you down. The fix: consolidate your storage into the compute node and cut the cord to the storage network altogether. Tier your storage media with a combination of flash (SSD) and traditional spinning disks to eliminate most of the performance problems associated with traditional distributed storage architectures.

What about those power users who need the performance of a GPU? Scientists, engineers and anyone using graphics-intensive applications need more umph to get their jobs done. AMD FirePro and NVIDIA GRID boards solve those problems with their shared and vGPU capabilities.

Now add storage management to that new local storage resource, and you will see performance equal to that of a physical workstation. This is the essence of a hyper-converged appliance: it enables your users to have access to all of their applications from anywhere in the world, on any device.
