General Description
1-2 C141-E219
1.1 Standard Features
(1) Compactness
The disk drive is a compact enclosure which complies with the 2.5" disk drive form factor.
(2) SAS Standard
The HDD is equipped with a serial attached SCSI (SAS) as a host interface.
• Transfer rate: 1.5Gbps, 3.0Gbps
• Number of SAS ports: One
• Full-duplex (simultaneous bidirectional data transfer) is supported.
SCSI commands can manipulate data through logical block addressing, regardless of the physical
characteristics of the disk drive. This enables software to accommodate expansion of system
functionality.
(3) Single SAS port support
The HDD has single pair of driver and receiver set (PHY) for the SAS to support single SAS port
connection.
On MAV2073RC and MAV2036RC, Primary Port on SAS plug connector (2 physical links plus
power connections) is used for SAS port connection.
(4) High-speed data transfer
The maximum data-transfer speed on the SAS is 300.0 MB/s. The large-capacity data buffer of the
HDD enables the effective use of such high-speed data transfers available on the SAS connection.
(5) Continuous block processing
The addressing method of data blocks is logical block address. The initiator can access data by
specifying block number in a logically continuous data space without concerning the physical
structure of the track or cylinder boundaries.
The continuous processing up to [64K-1] blocks in a command can be achieved, and the HDD can perform
continuous read/write operation when processing data blocks on several tracks or cylinder.
(6) Multi-segment data buffer
The data buffer is 8M bytes. Data is transferred between SAS port and disk media through this data
buffer. This feature provides the suitable usage environment for users.
