4.2.2

Format command execution time (minutes)

Maximum (with verify)
Maximum (without verify)
Execution time measured from receipt of the last byte of the Command Descriptor Block (CDB) to the request
for a Status Byte Transfer to the Initiator (excluding connect/disconnect).
When changing sector sizes, the format times shown above may need to be increased by 30 minutes.
4.2.3

General performance characteristics

Sustainable disk transfer rate*:
Minimum
Maximum
Fibre Channel Interface maximum instantaneous transfer rate
Logical block sizes
Default is 512-byte data blocks
Sector sizes variable to 512, 520, 524 and 528 bytes.
Read/write consecutive sectors on a track
Flaw reallocation performance impact (for flaws reallocated at format time
using the spare sectors per sparing zone reallocation scheme.)
*Assumes no errors and no relocated logical blocks. Rate measured from the start of the first logical block transfer to or
from the host.
4.3

Start/stop time

The drive accepts the commands listed in the Fibre Channel Interface Manual less than 3 seconds after DC
power has been applied.
If the drive receives a NOTIFY (ENABLE SPINUP) primitive through either port and has not received a START
STOP UNIT command with the START bit equal to 0, the drive becomes ready for normal operations within 30
seconds (excluding the error recovery procedure).
If the drive receives a START STOP UNIT command with the START bit equal to 0 before receiving a NOTIFY
(ENABLE SPINUP) primitive, the drive waits for a START STOP UNIT command with the START bit equal to 1.
After receiving a START STOP UNIT command with the START bit equal to 1, the drive waits for a NOTIFY
(ENABLE SPINUP) primitive. After receiving a NOTIFY (ENABLE SPINUP) primitive through either port, the
drive becomes ready for normal operations within 30 seconds (excluding the error recovery procedure).
If the drive receives a START STOP UNIT command with the START bit and IMMED bit equal to 1 and does
not receive a NOTIFY (ENABLE SPINUP) primitive within 5 seconds, the drive fails the START STOP UNIT
command.
The START STOP UNIT command may be used to command the drive to stop the spindle. Stop time is 30 sec-
onds (maximum) from removal of DC power.
There is no power control switch on the drive.
