Serial Attached SCSI is the logical evolution of SCSI, including its long-established software advantage and the Serial ATA electrical and physical connection interface. With enterprise storage requirements escalating and becoming more complex, factors such as larger capacity, greater density, security, scalability and accessibility are more critical than ever. Enterprise data centers must be online all the time, fulfill requests from numerous users simultaneously, allow for constant growth and expansion and be maintainedwhile in operation. Serial Attached SCSI meets all these demands while providing the highest performance.
SAS offers the most attractive disk drive alternative for enterprise users who want a solution far superior and more flexible than any other storage technology. The results of aligning the Serial Attached SCSI and Serial ATA technologies to serve storage users, who need large capacity at a lower cost, will provide even greater choice to the storage industry.
When used in conjunction with a SMART Array Controller and Systems Insight Manager, the SMART capable firmware in HP hard drives enables extensive fault prediction capabilities. If potential problems develop in one of the drives, the Smart Array Controller, Systems Insight Manager and/or SMART hard disk drive lets you know in advance so you can have the drive replaced, before it fails.
