Installation Damage
Never remove any labels from the drive or deface them in any way.

High temperature
To prevent injury, never touch the drive while it is hot. The DE and LSI
become hot during operation and remain hot immediately after turning off
the power.
5-1, 5-10
Damage
1. When dismounting the drive which is mounted on the
system while power is supplied to it.
• The spindle motor can be stopped by a START/STOP command. It
takes about 30 seconds for the spindle motor to stop completely.
• Then, dismount the drive using the drive mounting/dismounting
mechanism, etc. of the system. If the drive is dismounted while the
spindle motor is running, special care is required to avoid excessive
vibration or shock to the drive. It is recommended to stop the
operation once the connector breaks off contact and wait until the
spindle motor stops (about 30 seconds) before dismount the drive.
• When storing or transporting the drive, put it in the antistatic bag
(refer to Section 5.1).

CHAPTER 1 General Description
1.1 Standard Features
1.2 Hardware Structure
1.3 System Configuration
This chapter describes the feature and configuration of the hard disk drives (HDD).
The HDD are highperformance large capacity 3.5"fixed disk drives with an embedded Serial Attached SCSI
(SAS) controller.
The interface used to connect the HDD to the host system complies with ANSI T10/1601-D Serial Attached
SCSI-1.1 (SAS-1.1), which covers items ranging from SAS physical layers to SCSI command protocols.
The high-speed data transfer and long-distance transmission capabilities of SAS technology and the powerful
command set the HDD facilitate creation of high-performance and highly reliable disk subsystems with large
storage capacities.

General Description
1-2 C141-E222
1.1 Standard Features
(1) Compactness
The diskdrive is a compact enclosure which complies with the 3.5" diskdrive 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: Two
• 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) Dual SAS port support
The HDD has two pairs of driver and receiver set (PHY) for the SAS to support dual SAS port
connection.
On MAU3147RC, MAU3073RC, and MAU3036RC, Primary and Secondary Ports on SAS plug
connector (2 physical links plus power connections) are 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 16M bytes. Data is transferred between SAS port and disk media through this data
buffer. This feature provides the suitable usage environment for users.

1.1 Standard Features
C141-E222 1-3
(7) Cache feature
After executing the READ command, the HDD reads automatically and stores (prefetches) the
subsequent data blocks into the data buffer (Read-ahead caching).
The high speed sequential data access can be achieved by transferring the data from the data buffer without
reaccessing the disk in case the subsequent command requests the prefetched data blocks.
The Write Cache feature is supported. When this feature is enabled, the status report is issued
without waiting for completion of write processing to disk media, thereby enabling high speed write
processing.
When Write Cache is enabled, you should ensure that the cached data is
surely flushed to the disk media before you turn off the drive's power.
To ensure it, you should issue either the SYNCHRONIZE CACHE
command or the STOP UNIT command with specifying “0” to the
Immediate bit, and then confirm that the command is surely terminated
with the GOOD STATUS.
(8) Command queuing feature
The HDD can queue maximum 128 commands, and optimizes the issuing order of queued commands
by the reordering function. This feature realizes the high speed processing.
(9) Reserve and release functions
The HDD can be accessed exclusively in the multi-host or multi-initiator environment by using the
reserve and release functions.
(10) Error recovery
The HDD can try to recover from errors in the disk drive using its powerful retry processing. If a
recoverable data check occurs, error-free data can be transferred to the initiator after being corrected
in the data buffer. The initiator software is released from the complicated error recover processing
by these error recovery functions of the HDD.
(11) Automatic alternate block reassignment
If a defective data block is detected during read or write the HDD can automatically reassign its
alternate data block.
(12) Programmable data block length
Data can be accessed in fixed-block length units. The data block length is programmable, and can be
specified at initializing with a multiple of four within the range of 512 to 528 bytes.

General Description
1-4 C141-E222
Error rate increase
1. The drive format at factory shipment is generally 512 bytes.
2. The recoverable Error of the drive might increase when the format would
be modified from 512 bytes to the following values:
516 bytes, 520 bytes, 524 bytes, 528 bytes.
3. The recoverable Error referred here is sense data (1-13-xx).
(13) Defective block slipping
A logical data block can be reallocated in a physical sequence by slipping the defective data block at
formatting. This results in high speed contiguous data block processing without a revolution delay
due to defective data block.
(14) High speed positioning
A rotary voice coil motor achieves fast positioning with high performance access control.
(15) Large capacity
A large capacity can be obtained from the HDD by dividing all cylinders into several partitions and
changing the recording density on each partition (constant density recording). The disk subsystem
with large capacity can be constructed in the good space efficiency.
(16) Start/Stop of spindle motor
Using the SAS primitive or the SCSI command, the host system can start and stop the spindle motor.
(17) Diagnosis
The HDD has a diagnostic capability which checks internal controller functions and drive operations
to facilitate testing and repair.
(18) Low power consumption
By using highly integrated LSI components, the power consumption of the HDD is very low, and this
enables the unit to be used in wide range of environmental conditions.
(19) Low noise and low vibration
The noise level is low; approx. 3.5 Bels at Ready for the drive. This makes it ideal for office use.
