How is dm-cache configured on a RHEL 7 host?

Solution Verified - Updated -


dm-cache is a device mapper target that provides a generic block-level disk cache for storage. It aims to improve performance of a block device by dynamically migrating some of its data to a faster, smaller device such an SSD. How can dm-cache be configured on a RHEL 7 host?

Please note: dm-cache is fully supported in RHEL 7.1GA and later.
