Chassis Contents Information

Actual chassis contents depend on the model and options ordered. However, each
subsystem chassis contains one dual-slot Processor card.
Each Sun StorEdge A7000 model cabinet contains two identically-configured 14-slot
chassis. The Sun StorEdge A7000 Processor card is two boards and always occupies
slots 1 and 2.
Typically, chassis contents are configured as follows:
Slots 1/2 — Processor card
Slots 3/4/5/6 — cache memory cards
Slots 7 and above — I/O controller cards such as SCSI, BMC, and ESCON
