4.0 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 computing 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 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.trustedcomputinggroup.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. 4.1 Standard features Pulsar.2 SAS drives have the following standard features: 1.5 / 3.0 / 6.0 Gb Serial Attached SCSI (SAS) interface Integrated dual port SAS controller supporting the SCSI protocol Support for SAS expanders and fanout adapters Firmware downloadable using the SAS interface 128 - deep task set (queue) Supports up to 32 initiators Jumperless configuration User-selectable logical block size (512, 520, 524, 528, 4096, 4160, 4192, or 4224 bytes per logical block) Industry standard SFF 2.5-inch dimensions ECC maximum burst correction length of 96 bits No preventive maintenance or adjustments required Self diagnostics performed when power is applied to the drive Vertical, horizontal, or top down mounting Drive Self Test (DST) Background Media Scan (BMS) Parallel flash access channels Power loss data protection Thin Provisioning with Block Unmap Support Silent operation Lifetime Endurance Management (available on certain models) 6 Pulsar.2 SAS Product Manual, Rev.

Pulsar.2 SAS Product Manual, Rev. B

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).
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.
