Virtual machine files are stored in the high performance, high capacity flash storage layer using Shannon Direct-IO™ PCIe Flash:
In VMware View environment, storage I/O usually is the bottleneck for performance.
PCIe Flash offers the following benefits when deployed under VDI environment:
Shannon Direct-IO™ PCIe Flash can be deployed in VMware VSphere at the read cache layer. The cache is placed in front of a slower storage layer, which usually consists of SAS or SATA HDDs; with VMware VSphere Flash Read Cache function, frequently visited data is cached to improve the system I/O performance.
Shannon Direct-IO™ PCIe Flash, when deployed as vSphere Flash Read Cache, provide a high performance read cache layer, capable of greatly reducing application latency. In addition, it is completely transparent to applications and no client agent is needed. VSphere Flash Read Cache is capable of pricisely assigning flash cache resources to every VMDK, providing consistent read cache for vMotion, and utilizing virtualized resources to the fullest extent. VSphere Flash Read Cache eleminates the I/O bottleneck for virtual environment, and can accelert the performance of key applications by up to 20 to 30 times.
