4.0General description

Pulsar XT.2 drives provide high performance, high capacity data storage for a variety of systems with a Serial Attached SCSI (SAS) interface. The Serial Attached SCSI interface is designed to meet next-generation com- puting demands for performance, scalability, flexibility and high-density storage requirements.

Pulsar XT.2 drives are random access storage devices designed to support the Serial Attached SCSI Protocol as described in the ANSI specifications, this document, and the SAS Interface Manual (part number 100293071) which describes the general interface characteristics of this drive. Pulsar XT.2 drives are classified as intelligent peripherals and provide level 2 conformance (highest level) with the ANSI SCSI-1 standard. The SAS connectors, cables and electrical interface are compatible with Serial ATA (SATA), giving future users the choice of populating their systems with either SAS or SATA drives. This allows users to continue to leverage existing investment in SCSI while gaining a 6Gb/s serial data transfer rate.

The Self-Encrypting Drive models indicated on the cover of this product manual have provisions for “Security of Data at Rest” based on the standards defined by the Trusted Computing Group (see www.trustedcomputing- group.org).

Note. Never disassemble and do not attempt to service items in the enclosure. The drive does not contain user-replaceable parts. Opening for any reason voids the drive warranty.
