Abstract
Disclosed is a method of storage tiering with minimal use of DRAM memory for header overhead that utilizes the beginning of the volume to store frequently accessed or hot data. A solid state storage device is placed at the beginning of a tiered volume and is used to store frequently accessed data. When data becomes less frequently accessed it is moved to a cold data storage area on a hard disk drive in the tiered volume. The data exchange is performed on a one-to-one basis reducing the amount and use of DRAM.
