key benefits

• Online features: Online capacity expansion, RAID level migration, and online spare support reduce planned downtime.
• High Performance: 64 bit architecture optimizes data through put and performance.
• Software consistency and data compatibility across the Smart Array family line simplifies deployment.
• Mix and match LVD SCSI compatibility offers investment protection by mixing Ultra2 and Ultra3 on the same SCSI bus (Ultra2 devices will transfer data at 80 MB/s and Ultra3 devices at 160 MB/s).

The SA-431 provides one of the most cost effective alternatives to software based RAID in the market today-by lowering entry level and workgroup server ownership costs. In addition, the SA-431 is compatible with all LVD (Wide Ultra2 and Ultra3) drives and servers, therefore offering an unparalleled degree of investment protection.

	ideal environment

The SA-431 targets entry-level and workgroup ProLiant servers and any Compaq server where hardware RAID is needed at an entry-level price.

• Hardware-based RAID fault tolerance
• Need for increased performance and data bandwidth
• Investment protection in legacy Ultra2 servers, hard disk drives and storage

• A single Ultra3 channel allows for OS and data storage of up to 1TB.
• Consistent with Compaq's LVD strategy, the Smart Array 532 Controller can be used to mix and match Ultra2 and Ultra3 devices on the same Ultra3 SCSI bus. When Ultra2 devices and Ultra3 devices are found on the same Ultra3 SCSI bus, each Ultra2 device will transfer data up to 80 MB/s, while each Ultra3 device will transfer data up to 160 MB/s.

	the smart array advantage

The innovative design and integration work of the Compaq Smart Array family of products creates customer value unmatched in the industry. Use of Smart Array products in the enterprise results in a much lower Total Cost of Ownership (TCO) than any other server storage RAID products. The Compaq Smart Array family brings an unparalleled return on investment through:

• Data Compatibility - Smart Array controllers allow for simple and easy upgrades any time customers require higher performance, greater capacity, and/or increased availability. Every successive generation of Smart Array controllers understands the data format of other Smart Array controllers making upgrading quick and easy.
• Consistent Configuration and Management Tools - All Smart Array products utilize a standard set of management and utility software that minimize Total Cost of Ownership (TCO) by reducing training requirements and technical expertise.
• Universal Hard Drive - With form factor compatibility across many enterprise platforms, you can deploy and re-deploy these drives to quickly deliver increased storage capacity, migrate data between systems, and attain easier to manage spare drives.
  
• Pre-Failure Warranty - Compaq Insight Manager not only reports when a drive is going to fail, but also allows replacement of failing drives prior to actual failure. For complete details, consult the Compaq Support Center or refer to your Compaq Server documentation.
