HP 300 GB 10K Internal Disk Drive AD149A

AD149A is a 300 GB, 10,000 RPM internal disk drive for the HP Integrity rx7620, rx8620, rx7640 and rx8640 and the HP 9000 rp7420, rp8420, rp7440 and rp8440 servers. It is a low profile, hot plug drive. Average seek time is 4.7 msec for reads and 5.2 msec for writes, and sustained bandwidth is 69 MB/s.

Each of these servers, for example the HP Integrity rx7620 or the HP 9000 rp8420, takes up to four internal low profile hot plug disk drives. Access to two internal drives comes with the first core I/O board set, and the second core I/O board set must be ordered to reach the third and fourth drives.

Under HP-UX the drive is supported by MirrorDisk/UX across disk drives, controllers and core I/O boards. On the rx8620, rx8640, rp8420 and rp8440, UltraSCSI controllers provide each drive with an independent SCSI channel.

Disk drives from earlier models carry forward: HP 9000 rp7410, rp7420 and rx7620 drives can move to the rp7440, and rp8400, rp8420 and rx8620 drives can move to the rp8440.

Other drives for the rx7620, rx8620, rx7640, rx8640, rp7440 and rp8440 include the 36 GB and 73 GB 15,000 RPM drives AD146A and AD147A and the 146 GB 10,000 RPM drive AD148A.
