Introduction
Hitachi AMS 2100/2300 Storage System Hardware Guide
:
• To use AMS 2100/2300 systems efficiently, Hitachi Data Systems
recommends that users mount a spare drive in each of the unused
drive slots. Up to 15 spare disks can be set up in any location with an
AMS 2100 and up to 30 spare disk drives with an AMS 2300.
• From the host computer, the array can be used not only as a single-
large scale disk drive but also as 2048 logical disks (logical units)
maximum in an AMS 2100 and 4096 logical units in an AMS 2300.
Fibre channel interface
The AMS2100/AMS2300 supports open system operations. The AMS2100/
AMS2300 supports up to 4 fibre-channel ports. The AMS2300 Fibre Channel
interface is capable of operating at data transfer speeds of up to 800 MB/
sec. The AMS2100 Fibre Channel interface is capable of operating at data
transfer speeds of up to 400 MB/sec. The AMS2100/AMS2300 supports
shortwave multimode optical cables. With these shortwave fibre channel
cards, the AMS2100/AMS2300 can be located up to 860 meters from the
open-system host.
2. Maximum number of disk drives using intermix of expansion units and high-
density expansion units.
3. Maximum number of disk drives using only expansion units.
