Preface
About this Manual
Welcome
Congratulations on the purchase of your new OmniStor 4000S Series JBOD Storage
System from Rackable Systems. The OmniStor 4000S Series is a very high-performance
fully fault-tolerant Ultra320/160 SCSI storage system. Its unique 2U design is optimized to
fit in the compact space of today’s data center rack enclosures and as a deskside tower
system.
At its core is the OmniStor 4000S Ultra320/160 SCSI JBOD storage enclosure which
supports up to twelve hot pluggable 1-inch high Ultra320 or Ultra160 disk drives all in a 2U
(3.47-inch) form factor enclosure. Full component redundancy is provided through hot
pluggable cooling fan module and independent power supplies.
This user’s guide is your complete documentation to set up the storage system hardware,
add components, cable the storage system components, replace parts, and diagnose/repair
your system.
For information on the software control, management and configuration, refer to one of
the following: VT-100 Software Guide or the AdminiStor Software Guide.

Features
The OmniStor 4000S Series Storage Systems is designed for mission critical applications
requiring the highest performance with uncompromised data reliability, such as mid-range
and enterprise server storage. They maintain exceptionally high throughput and are ideally
suited for high bandwidth data intensive applications, such as electronic commerce, digital
video, CAD, seismic research, digital pre-press, and 3-D imaging.
The following are major features of the OmniStor 4000S
Series Storage Systems:
nUltra320/160 storage system enclosure.
nUltra160-to-Ultra160 SCSI RAID Controller.
nSupports up to 12 drives in JBOD mode.
nA standard AC power supply with an option for a redundant second power supply.
nOptional DC power supply with an option for a redundant second power supply.
nDesigned to fit standard 19-inch rack enclosures or a deskside tower.
nFront panel LEDs provide notifications of system component status, and logical
and physical drive status.
nSequential data transfers from disk arrays at over 320 MB per second sustained in
JBOD mode.
nOperating system independent – no special software or drivers required.
nUltra320/160 low-voltage differential single (LVDS) host ports.
nUp to thwo 320/160 MB/sec SCSI disk channels
nSupports clustering environments.
nAll SCSI channels are backward compatible Ultra2 LVD and
Ultra/Fast/Asynchronous single-ended SCSI modes.
nAll SCSI channels support SPI-3 Cyclic Redundancy Check (CRC) and Domain
Validation.
nSupport for just a bunch of disks (JBOD).
nFirmware can be upgraded either in-band over the SCSI bus or out-of-band via the
RS-232 service port.
n
nContinuous runtime diagnostics for warnings and automatic shutdown for
out-of-spec temperature and voltages, and internal errors.
