Embodiment Construction

[0019] A. Data Archive Environment

[0020] figure 1 is a schematic block diagram of an environment 100 including a storage system that may be configured to provide the data archival storage system of the present invention. Storage system 120 is a computer that provides storage services related to organizing information on writable persistent electronic and magnetic storage media. To this end, storage system 120 includes processor 122 , memory 124 , network adapter 126 , storage adapter 128 , and electronic storage media 140 interconnected by system bus 125 . The storage system 120 also includes a storage operating system 200 that implements a virtualization system to logically organize information on the electronic and magnetic storage media 140, 150 into data containers (such as files and logical elements (luns)) hierarchical structure.

[0021] Memory 124 includes processor and adapter addressable storage locations for storing software programs and data structures ass...

Abstract

A flash-based data archive storage system having a large capacity storage array constructed from a plurality of dense flash devices is provided. The flash devices are illustratively multi-level cell (MLC) flash devices that are tightly packaged to provide a low-power, high-performance data archive system having substantially more capacity per cubic inch than more dense tape or disk drives. The flash-based data archive system may be adapted to employ conventional data de-duplication and compression methods to compactly store data. Furthermore, the flash-based archive system has a smaller footprint and consumes less power than the tape and / or disk archive system.

Description

[0001] related application [0002] This application claims priority to Steven C. Miller et al., US Provisional Application Serial No. 61 / 174,295, FLASH BASED DATA ARCHIVE STORAGE SYSTEM, filed April 30, 2009, the contents of which are hereby incorporated by reference. technical field [0003] The present invention relates to storage systems and more particularly to data archival storage systems. Background technique [0004] A storage system is a computer that provides storage services related to organizing data on writable persistent storage media, such as non-volatile memory and disks. The storage system may be configured to operate according to a client / server model of information delivery to thereby enable multiple clients (eg, applications) to access data served by the system. A storage system generally employs a storage architecture that supplies data in both a file system format and a block format having both a random mode and a stream access mode. Disks generally...
