Introduction

Bcache is a block layer cache of the Linux kernel. It uses SSDs as the cache of HDDs for acceleration. The bcache kernel module is supported only by Linux 3.10 or later. Therefore, before using bcache, 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:
