Interface Values:380 = Ultra 320, 80 pin 360 = Ultra 320, 68 pin F20 = Fibre Channel, 2GB Note (1) - Additional block assignment will be issued as needed based on actual production volume Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...
Note: All the above parameters contribute to drive performance. There are other parameters that contribute to the perfor- mance of the actual system. This specification tries to define the bare drive characteristics, not system throughput, which depends on the system and the application.

= Maximum seek length = Seek length (1 to max) Tn.in = Inward measured seek time for an n track seek Tn.out = Outward measured seek time for an n track seek Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...
Full stroke seek is measured as the average of 1,000 full stroke seeks with a random head switch from both directions (inward and outward). 4.5.1.3 Average latency Table 8: Latency time Rotation Time for a revolution (ms) Average latency (ms) 15,000 RPM Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...
Instantaneous disk-buffer transfer rate is derived by: (Number of sectors on a track) x 512 x (revolutions/sec) • For this table, '1 MB / Sec' should be interpreted as 1,000,000 bytes per Second. • The number of sectors per track will vary because of the linear density recording. Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...
T = A + B + C + 16,777,216/D Where: T = Calculated time A = Command overhead (no cache hit) B = Average seek time C = Average latency D = Sustained disk-buffer transfer rate Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...
An approximation for the time is: T = (A + B + C) * 4096 Where: T = Calculated time A = Command overhead (no cache hit) B = Average seek time C = Average latency Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...

Page 126
Note: DPOFUA is ignored during Mode Select command processing although the SCSI Standard states that it is reserved during Mode Select. Ignoring it allows the Mode Sense Parameter List for the byte containing this bit to be re-used as a Mode Select Parameter List. Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...
A FORMAT UNIT command is required to cause these parameters to become current only if the block length param- eter is different from the current block length. When used with the MODE SENSE command, the field is dependent on how the media is currently formatted. Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...
The page length field specifies the length in bytes of the mode parameters that follow. If the Initiator does not set this value to the value that is returned for the page by the MODE SENSE command, the drive will terminate the command with Check Con- dition status. Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...
• CMDAC (Command Active) bit in conjunction with LED Mode bits determines if an LED on the drive is activated while commands are active. If CMDAC bit is one and LED Mode bits are zero, an LED driver is active when a com- mand is queued or executed. Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...

The drive sends this message to the Initiator to indicate that the execution of a command has been terminated and that valid status has been sent to the Initiator. After successfully sending this message the drive releases all bus signals and goes to BUS FREE phase. Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...
If ATN is negated before all bytes of a multiple-byte extended message is received, the drive will go to BUS FREE to signal a catastrophic error. 19.1.2.1 Synchronous Negotiation started by the Initiator When the Target responds with REQ/ACK offset value of 0, the Initiator shall use asynchronous data transfer mode.

The implied data transfer width agreement remains in effect until the Target is Reset (Power-on Reset, SCSI Bus Hard Reset, or Target Reset message) or a new data transfer width agreement is negotiated.

If the Initiator does assert the ATN signal, the Target changes to the Message Out phase and receives a message from the Initiator.

Incorrect Initiator Connection will not cause Queue Full status. 20.3.6 Device Behavior on Command Queuing 1. Initiators must send a Queue tag immediately after the Identify message in Message Out phase just after Selection. Tar- Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...
If the drive detects an error after it returns a Good Status, the drive sets a Deferred Error (Error Code of sense data = 71h) and a following command will be returned with Check Condition and the Contingent allegiance condition is established. Under the Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...
Read(6) • Read(10) • Verify • Verify Portion of Write and Verify For all other commands the ARRE setting is ignored and the target will not automatically rewrite/ reallocate or recommend rewrite/reassign. Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...

Single Initiator Selection with only one ID bit present during selection. The initiator must not send an Identify message with the disconnect permission bit(6) on. 20.12 Non-arbitrating systems The Target cannot detect whether other SCSI devices on the SCSI bus use arbitration prior to selection. As a consequence the Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...
After a reset condition is detected and the reset actions completed, the target returns to a 'SCSI bus enabled' state that allows the target to accept SCSI commands. This device uses the Hard reset option as defined in the SCSI-3 standard. Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...

When the drive receives a SEND DIAGNOSTIC command specifying a self-test to be performed in the background mode, the drive will return status for that command as soon as the command descriptor block has been validated. After returning status Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...

A time-out of one minute or more is recommended but NOT required. The larger system time-out limit allows the system to take advantage of the extensive ERP/DRP that the drive may attempt in order to successfully complete the startup sequence. Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...
The command time-out for a command that is not located at the head of the command queue should be increased by the sum of command time-outs for all of the commands that are performed before it is. Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...
The first priority is to replace the entire drive to make the system operational with minimal service time. The service rep- resentative should: 1. Back up all the customer data on this drive if possible 2. Replace the complete drive 3. Restore the customer data 4. Return the drive to customer service Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...
Failure of the system to properly relocate defective media sites can have a direct influence on system throughput and drive error rates. Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...

If the retry of the failing command completes with Recovered sense or Hardware error sense, then service the drive using the service guideline recommended in Section 20.20.1, “Drive Service Strategy” on page 252. Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...

Recovery for a failed power up sequence is achieved in one of the following ways: Issuing a Unit start (1B) command Power cycling the drive. If the failure repeats, service the drive using the service guideline recommended in Section 20.20.1, “Drive Service Strategy” on page 252. Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...

1/1C/01 or 1/1C/02, the requested defect list is not in the format that the Drive supports. The requested defect list is returned in the physical (cylinder, sector, head) format. This is the default format. There is no initiator action required for this condition. Hitachi Ultrastar 15K147 SCSI Hard Disk Drive Specification...
Service for this drive can be deferred. The longer service is deferred, the more probable a failure can occur that will require immediate service. If more than this drive is experiencing error activity, the drive is probably not at fault. Locate and service the outside source causing error activity on this drive.
