Bcache is a Linux kernel block layer cache. It allows SSDs to act as a cache for slower HDDs. The Bcache kernel module is supported only by Linux 3.10 or later. Therefore, before using Bcache, you need to upgrade the kernel to 3.10 or later and enable the Bcache module in the kernel configuration.
To facilitate the use of Bcache, this document provides the process for making the following files:
- Bcache kernel RPM package
- Bcache-tools RPM package
- ISO image that contains the Bcache kernel RPM package and the Bcache-tools RPM package
For details, see the Bcache home page and user guide:
