UltraSCSI Configuration Rules

• UltraSCSI configurations require UltraSCSI components (controllers, adapters, shelves, disks, and cables).

• UltraSCSI adapters and RAID controllers support UltraSCSI disks at UltraSCSI speeds in UltraSCSI top gun blue

shelves (DS-BA356-xx).

• Fast10 BA356-xx SCSI shelves cannot be retrofitted; replace Fast10 SCSI shelf with DS-BA356-xx shelf when

adding an UltraSCSI disk and when connecting to UltraSCSI adapter.

• UltraSCSI and Fast10 drives can be mixed in DS-BA356 top gun blue UltraSCSI shelf; UltraSCSI adapter

negotiates maximum transfer speed of drives.

UltraSCSI StorageWorks Shelves

• UltraSCSI top gun blue shelf provides support for UltraSCSI disk drives. The shelf is available in single-bus or

split-bus configurations, and the shelf includes personality module and 180W power supply.

• UltraSCSI shelf supports seven 3.5″ hard disk drives, or one 5.25″ device and four 3.5″ hard disk drives, or two

5.25″devices and one 3.5″ hard disk drive

• Installation of redundant power supply reduces number of 3.5″ drive slots by one.
