• Disk drive modules with speeds of 10 000 or 15 000 rpm
• A battery-backed mirrored cache
• Four GB of cache and the following features shown in orange in the diagrams:

Two fibre-channel processor cards
Two battery-backup units, one for each processor
Two fully redundant ac/dc power supplies with enclosure-cooling units
Two, four or eight 2 Gbps fibre-channel or IBM fibre-channel connection (IBM FICON®) host ports
