The system cabinet houses the disks and the PCI subsystem. Each contains an imbedded single-ended SCSI interface that supports synchronous transfer. The back of the cabinet contains the two PCI card cages. Each card cage can accommodate up to seven PCI cards in multiple combinations for disk and communications connectivity, for a total of 14 cards. Power Supply Power supplies in each suitcase ensure that your system stays powered up and running at capacity.
Power is distributed to the system via two separate paths.
Each path can fully support operation of the system in the event the other fails. Duplex power is also supplied in the cabinet base, providing fault-tolerant power to the disk drives and system clock. Each power supply also supports one of the system's two PCI card cages. This design ensures that half the PCI subsystem is powered in the event of power failure.
