VMware vFRC (VMware vSphere Flash Read Cache)

VMware vFRC (VMware vSphere Flash Read Cache) is a feature that allows a host to use a local solid-state drive (SSD) as a caching layer for virtual machines (VMs).

VMware vFRC can improve performance by moving I/O loads from shared storage. This approach reduces latency and can significantly improve performance. VMware vFRC can also help lower costs by reducing the capacity of expensive storage area networks (SANs) in favor of local SSDs, which have recently fallen in price. Virtualization administrators can enable vFRC and select the cache size reservation from the vSphere Web Client.

VMware first introduced the concept of vFRC as vFlash at VMworld 2012. VMware vFRC is included with vSphere 5.5, which was released in August 2013.
