AMS 2300 configuration architecture

This section contains the configuration block diagrams of the AMS 2300
base unit. Each controller in the base unit contains four Fibre Channel ports
or two iSCSI ports. The AMS 2300 includes the following features:
• An AMS 2300 base unit and expansion unit can mount up to 15 disk
drives each. A high-density expansion unit can mount up to 48 disk
drives each. See
about the number and type of disc drives that can be installed in each
unit.
• An AMS 2300 base unit includes two control units that can control up to
240 disk drives each in a RAID configuration.
• The disk drives in the base unit, expansion units, and high-density
expansion units can be assigned to data disk(s), parity disk(s) or
(mirror disk(s)) depending on the RAID level.
• Up to 30 spare disks can be mounted in any locations within an AMS
2300 configuration.
