AD147A is a 73 GB, 15,000 RPM internal disk drive for the HP Integrity rx7640 and HP Integrity rx8640. It is a low-profile hot-plug drive with an average seek time of 3.6 msec for reads and 3.9 msec for writes. Each server holds up to four internal low-profile hot-plug disk drives.
Access to the first two drives comes with the primary core I/O board set, and a second core I/O set is ordered for the third and fourth drives. Under HP-UX the drives are supported by MirrorDisk/UX across disk drives, controllers and core I/O boards. Drives from the earlier rp7410, rp7420 and rx7620 carry forward to the rx7640, and drives from the rp8400, rp8420 and rx8620 carry forward to the rx8640.
The larger 15,000 RPM drives in the same disk table are AD210A at 146 GB and AD265A at 300 GB. The spare drives tied to AD147A are AB421-67001 and AB421-69001, a 73 GB hot-plug Ultra320 low voltage differential SCSI hard drive at 15,000 RPM in a 3.5-inch form factor, 1.0-inch high.
