Step 7a—StorageWorks Expansion Packages ( continued)
SW820/SW821 StorageWorks Expansion Packages—all BA356 shelves operate in split-bus mode.
All SW82x StorageWorks Expansion Packages include redundant power supplies (BA35X-HF)—this reduces the number of available slots in each BA356 shelf to six in the SW822 and three on each split-bus of the SW820/SW821.

Step 7b—External Storage (I/O Expansion Cabinet)
I/O expansion cabinet (H9F00-BA/BB/BC/BD) provides space for up to six SCSI disk plug-in units (PIU) if no other PCI/XMI plug-in unit (PIU) is configured in the expansion cabinet. Each of the two pairs of expansion bays in the bottom of the cabinet can hold one Battery PIU, one PCI PIU, one XMI PIU, or two SCSI disk PIUs. Two expansion bays in the top of the expansion cabinet can hold up to two SCSI disk PIUs. Disk and tape drives supported are the same as Step 7 Internal Storage.
