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
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.
