Reducing latencies in vGPU assisted VDI

VirtuCache is installed in VMware vSphere kernel. It then automatically caches frequently and recently used data from any backend storage to any high speed media (RAM/SSD) in the VMware host. By bringing large amounts of 'hot' data closer to the VMware host GPU and CPU, VirtuCache improves the performance of all applications running within VMs including GPU assisted operations.

VMware’s vFlash Read Cache (VFRC) versus Virtunet’s Read+Write Caching

Here are the three biggest differences. We cache reads and writes, VMware's VFRC caches only reads. Caching writes improves the performance of not only writes, but also of reads, and even in a read dominated workload.1 We require no ongoing administration. Caching in our case is fully automated. All Vmware features are seamlessly supported. Versus VFRC that requires administrator intervention when doing vmotion, for creating a new VM, for maintenance mode, for VM restore from backup, VFRC...
