A half-rack of capacity made up by an AC72 base unit and five expansion units.
From a hardware standpoint, the AC72 is modular, meaning that a single based controller unit can be expanded with multiple units.
The storage array comes with four models: an AC72 7.2TB base configuration that includes a controller with three SSDs and twelve 15,000-rpm SAS drives, an ES16 expansion unit for the latter; a high-capacity AC72 base unit that includes a controller with three SSDs and 24TB of nearline 7,200-rpm SAS drives; and ES45 high-capacity expansion unit for the latter.
The ES16 expansion unit is 3U (5.25-in high) and has 16 drive bays that can be populated with SAS drives with 600GB to 2TB each. The ES45 expansion unit comes with 45 drive bays in a 4U enclosure.
The AC72 scales up to 474TB.
The base units are built on a single Intel Xeon 5600 processor and have 24GB of DDR3 memory, while expansion units run on dual Intel Xeon 5600 chips and have 48GB of DDR3 memory.
The AC72 base unit retails for $79,995; two ES16 expansion units or one ES45 expansion unit retails for $59,995.
