Abstract
A RAID storage system serializes data blocks to be stored in a RAID storage array and uses a primary map table and a number of secondary map tables to relate host addresses to logical block addresses in the storage array. Secondary map tables and other metadata can be cached from the storage array. The dual or two-tier map scheme and metadata caching promote scalability.
