Storage is a trust business. Sun's new line of integrated storage appliances provide the reliability, availability, and serviceability (RAS) attributes necessary to preserve customer data and meet enterprise expectations. Some aspects of RAS for storage are well defined by IT organizations and the industry. Sun's Open Unified Storage systems meet these requirements by delivering features such as RAID-6, active-active clustering, integrity checking, redundancy, replication, and snapshot capabilities. Other aspects of the RAS design of Sun's Open Unified Storage systems are new to the industry and offer exceptional value. In particular, the use of NAND Flash devices in conjunction with the Solaris ZFS file system defines a unique, highly reliable architecture that aims to provide the best possible price for performance ratio.
This article provides an overview of the RAS features of Sun Storage 7000 Unified Storage Systems. The content of this article assumes a basic understanding of common enterprise-class storage features and the Solaris ZFS file system.
