PHYSICALLY-ADDRESSABLE SOLID STATE DISK (SSD) AND A METHOD OF ADDRESSING THE SAME

摘要

A storage system includes a Central Processing Unit (CPU) that has a physically-addressed solid state disk (SSD) and is addressable using physical addresses associated with user data that are provided by a host. The user data is to be stored in or retrieved from the physically-addressed SSD in blocks. Further, a non-volatile memory module is coupled to the CPU and includes flash tables used to manage blocks in the physically addressed SSD. The flash tables have tables that are used to map logical to physical blocks for identifying the location of the user data in the physically-addressed SSD. The flash tables are maintained in the non-volatile memory modules.

1. A storage system comprising:
a Central Processing Unit (CPU): at least one physically-addressed solid state disk (SSD) that is addressable using physical addresses associated with user data, the at least one physically-addressed SSD being provided by a host, the user data to be stored in or retrieved from the at least one physically-addressed SSD in blocks; a non-volatile memory module coupled to the CPU and configured to store changes to tables, the tables used to map logical to physical block addresses for identifying the location of stored data in the at least one physically-addressed SSD, wherein the tables are moved to the at least one physically-addressed SSDs and the changes to the tables are maintained in the non-volatile memory module; and a network interface controller coupled through a bus to the CPU.
