General description

Pulsar.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.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.2 drives are classified as intelligent
peripherals and provide level 2 conformance (highest level) with the ANSI SCSI-1 standard. The SAS connec-
tors, 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).
