Cache Group Overview

> Cache Group Overview

> The Nytro XD solution introduces the concept of cache group to manage the cache devices and virtual drives. A cache group is a collection of devices that are involved in caching. The cache group called, XD-CGRP, gets created as part configuration of the first cache device. This is the only cache group supported in the current release of the Nytro XD solution. The following figure illustrates a cache group.

> NOTE When a cache group becomes inactive, the I/O requests bypass the cache and are directly issued on the VDs.
