What is vSphere Flash Read Cache?

vSphere Flash Read Cache is a new Flash-based storage solution from VMware that is fully integrated with
vSphere. The vSphere Flash Read Cache design is based on a framework that enables the virtualization and
management of local Flash-based devices in vSphere.
The framework provides a centralized management platform for all locally attached Flash-based devices, and it
maximizes their utilization throughout virtualized infrastructures.

The vSphere Flash Read Cache framework design is based on the following two major components:

•    vSphere Flash Read Cache infrastructure

•    vSphere Flash Read Cache software

• vSphere Flash Read Cache Infrastructure

The vSphere Flash Read Cache infrastructure integrates the vSphere hosts’ locally attached Flash-based devices into the  vSphere storage stack.  

This integration delivers a Flash management platform that enables the pooling of Flash-based devices into a Virtual Flash Resource

• Virtual Flash Read Cache Software  

The Virtual Flash Read Cache software is natively built into the vSphere core hypervisor. Virtual Flash Read Cache provides a write-through cache mode that enhances the performance of virtual machines without the modification of applications and operating systems (OSs)
