What is SAS? Serial Attached SCSI (SAS) is the evolution of the SCSI interface. SAS Enterprise drives satisfy the

enterprise data center requirement of scalability, performance, reliability and manageability, while

providing an enterprise storage infrastructure for both enterprise SAS drives and SATA disk drives. SAS

Midline drives provide the lowest dollars per gigabyte and economical reliability and performance. The

SAS interface is compatible with SATA devices. This compatibility provides users with unprecedented

choices for server and storage subsystem deployment

Today's distributed enterprise is seeing larger, more complex applications, an increase of mission-critical

data moving to the server, increasing demand for transaction processing and critical server

consolidation. In this environment, storage has become a critical component of the information system,

significantly defining both the systems reliability and performance. This is why HP drives undergo an

intense qualification process that eliminates firmware and O/S incompatibilities. All drive firmware is

specific to our drives and is designed to maximize both functionality and compatibility. All drives are

proven to perform in the HP systems for which they were designed.

While selecting the drives in our Enterprise portfolio, only those drives whose performance is suitable for

an enterprise environment are selected through the HP qualification process and are labeled "best-inclass." All our Enterprise drives are proven to be reliable and tuned for optimum performance in the HP

equipment for which they were designed. The drives in our Midline portfolio undergo a similar

qualification process to ensure that you get the economical reliability and performance you need for your

low workload (less than 40% I/O) environments.

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, under warranty
