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 high performance large capacity 2.5" 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 reliab le d isk subsystems with large storage capacities.
C141-E219 1-1
General Description

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 proce ssing
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 th e HDD can perform
continuous read/write operation when processing data blocks on several tracks or cylinder.
(6) Multi-segment data buffer The data buffe r is 8M bytes. Data is transferred between SAS port and disk med i a through this data
buffer. This feature provides the suitable usage environment for users.
1-2 C141-E219
1.1 Standard Features
(7) Cache feature
After executing the READ command, the HDD reads automatically and sto r es (prefetches) the
subsequent data blocks into the data buffer (Read-ahead caching).
The high speed sequential data access can be achieved by tran sferrin g th e data from the data bu ff er w ithou t
reaccessing the disk in cas e the su bsequen t com m and reques ts the pref etched data block s.
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 befo re 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 fe ature
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.
C141-E219 1-3
General Description
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. 2.9 Bels at Ready for the drive. This makes it ideal for office use.
1-4 C141-E219
1.1 Standard Features
(20) Microcode downloading
The HDD implements the microcode download feature. This feature achieves easy maintainability of
the HDD and function enhancing.

1.2 Hardware Structure

The HDD is composed of the disks, heads, and spindle motor mounted disk enclosure (DE) with
actuator as well as read/write pre-amp with the printed circuit assembly (PCA) of the controller.
(1) Disks
The disks have an outer diameter of 65 mm (2.56 inch).
(2) Heads
The heads have MR (Magnet-Resistive) read element Ramp Load type slider.
(3) Spindle motor
The disks are rotated by a direct-drive hall-less DC motor. The motor speed is controlled by a
feedback circuit using the counter electromotive current to precisely maintain the specified speed.
(4) Actuator
The actuator, which uses a rotary voice coil motor (VCM), consumes little power and generates little
heat. The heads at the end of the actuator arm are controlled and positioned via feedback servo loop.
The heads are positioned on the ramp when the power is off or the spindle motor is stopped.
(5) Read/write circuit
The read/write circuit utilizes a read channel mounted with a head IC that supports high-speed
transmission and an MEEPR4ML (Modified Enhanced Extended Partial Response Class 4 Maximum Likelihood) modulation/demodulation circuit in order to prevent errors being triggered by external noise and to improve data reliability.
(6) Controller circuit
The controller circuit uses LSIs to increase the reliability and uses a high speed microprocessing unit
(MPU) to increase the performance of the SAS controller.
C141-E219 1-5
General Description

1.3 System Configuration

For the Serial Attached SCSI, the ANSI standard defines Point-to-Point technology. Figure 1.1 and
Figure 1.2 give examples of the SAS system configuration.
Figure 1.1 Example of SAS system configuration (Single port internal cabled environment)
Figure 1.2 Example of SAS system configuration (Single port internal backplane environment)
(1) Port addressing
Every device connected with the SAS protocol has a unique address (SAS address). SAS addresses
are in the Name Address Authority (NAA) IEEE Registered format defined by SCSI Primary Command-3 (SPC-3).
An SAS address consists of 8 bytes as a unique value set for each device.
The initiator can implement an I/O operation on a disk drive by using the corresponding SAS address
stored by the HDD.

2.1 Hardware Specifications
(*1) For detail condition, see Section 4.1.
(*2) Vibration applied to the drive is measured at near the mounting screw hole on the frame as much as
possible.
(*3) At random seek write/read and default on retry setting with log sweep vibration.
(*4) At power-off state after installation Vibration displacement should be less than 2.5 mm.
(*5) Input voltages are specified at the drive connector side, during drive ready state.
(*6) High frequency noise (over 20MHz) is less than 100 mVp-p.

2.1.4 Error rate

Errors detected during initialization and replaced by alternate block assignments are not included in
the error rate. Data blocks to be accessed should be distributed over the disk medium equally.
(1) Unrecoverable error rate
Errors which cannot be recovered within 63 retries and ECC correction should not exceed 10 per
16
bits read.
10
(2) Positioning error rate
8
Positioning errors which can be recovered by one retry should be 10 or less per 10
seeks.

2.1.5 Reliability

(1) Mean Time Between Failures (MTBF)
MTBF of the HDD during its life time is 1,400,000 hours (operating: 24 hours/day, 7 days/week
average DE surface temperature: 50°C or less).
Note:
The MTBF is defined as:
Operating time (hours) at all field sites
MTBF=
The number of equipment failures from all field sites
Failure of the equipment means failure that requires repair, adjustments, or replacement.
Mishandling by the operator, failures due to bad environmental conditions, power trouble, host system trouble, cable failures, or other failures not caused by the equipment are not considered.

Specifications
(2) Mean Time To Repair (MTTR)
MTTR is the average time taken by a well-trained service mechanic to diagnose and repair a drive
malfunction. The drive is designed for a MTTR of 30 minutes or less.
(3) Service life
The service life under suitable conditions and treatment is as follows.
The service life is depending on the environment temperature. Therefore, the user must design the
system cabinet so that the average DE surface temperature is as low as possible.
DE surface temperature: 40°C or less 5 years
DE surface temperature: 41°C to 45°C 4.5 years
DE surface temperature: 46°C to 50°C 4 years
DE surface temperature: 51°C to 55°C 3.5 years
DE surface temperature: 56°C to 60°C 3 years
DE surface temperature: 61°C and more Strengthen cooling power so that DE surface
temperature is 60°C or less.
Even if the HDD is used intermittently, the longest service life is 5 years.
Note:
The "average DE surface temperature" means the average temperature at the DE surface
throughout the year when the HDD is operating.
(4) Data security at power failure Integrity of the data on the disk is guaranteed against all forms of DC power failure except on
blocks where a write operation is being performed. The above does not applied to formatting disks or assigning alternate blocks.
