The StorCase Technology Data Silo ® DS550 SCSI expansion chassis provides rugged and
reliable housing for 5.25" or 3.5" form factor, full-height, half-height, or low-profile (up to 1" high)
SCSI devices. DS550 units accommodate standard SCSI hard disks, tape drives, optical drives,
RAID controllers, and other SCSI devices, as well as the StorCase Data Express ® removable
device enclosures.
The DS550 can house any combination of up to nine (9) half-height, twelve (12) low-profile
(additional mounting brackets are required), or four (4) full-height SCSI peripherals. Using the
Data Express DE300 removable drive system, the DS550 can be configured to support up to
twelve (12) removable 3.5" form factor, low-profile (up to1" high) drives.
The DS550 is available unwired, with options for 50-pin Microminiature (HD50), 68-pin High
Density, or 68-pin VHDCI (used for SCSI Ultra2 and Ultra160) internal cabling and rear panel
connections. With optional, rear panel I/O plates, the DS550 can be configured to support up
to twelve (12) interfaces. StorCase offers a variety of optional DS550 internal cables to suit
most configuration requirements. Check the StorCase web site for available cable options.
The DS550 is available in both rack mount and tower configurations. Rack mount DS550 models
can be converted to tower models, and vice-versa. Both chassis models are constructed of
rugged steel and equipped with dual load-sharing, hot-swappable 400W auto-ranging power
supplies, two (2) high-pressure adjustable dual-speed blowers, and seven (7) diagnostic
LEDs on the front panel for chassis condition monitoring and status. The DS550 accommodates
up to six (6) SCSI I/O channels available in 50-pin MM (HD50), 68-pin HD, or 68-pin VHDCI
interfaces on the rear panel. Removable front filler panels allow installation of either fixed or
removable devices and contain drive activity and device fault indicator LEDs.
A SAF-TE Processor Board is available as an upgrade to the DS550 chassis. Refer to Appendix
