#5107 30 Disk Expansion

The #5107 is a disk unit expansion enclosure feature for the #9094 Base PCI I/O
Enclosure. The #5107 includes two 15 disk unit enclosures, one 840-watt power
supply, backplanes, and cables.
A #2757 PCI-X Ultra RAID Disk Controller or #4748/#4778 PCI RAID Disk Unit
Controller or #5703 PCI-X RAID Disk Unit Controller is required to support disk
units in each of the two disk unit enclosures included with #5107. Each group of
15 disk units is further divided into three groups of five disk units with each group
of five disk units supported on a separate SCSI bus. A minimum of two disk unit
controllers and a maximum of six are required to support 30 disk units.

#8094 Optional 1.8 M I/O Rack

The #8094 is a optional base I/O rack shipped on the Model 870 instead of the
#9094 Base PCI I/O Enclosure. The #8094 supports up to 90 disk units, up to 22
PCI IOAs, and up to three additional removable media units. A #8094 is a 1.8 M
rack with two enclosures.
The bottom enclosure is a #9094 Base PCI I/O Enclosure with side covers
and casters removed and a #5107 30 Disk Expansion included in the base
(no feature code required). The #5114 Dual Line Cords - Tower is a
mandatory feature for the #9094.
The top enclosure is a #5094 PCI-X Expansion Tower with side covers and
casters removed, and a #5108 30-Disk Expansion Feature (no feature code
required) included in the base. The #5115 Dual Line Cords - Tower feature
code is required for dual line cords in the top enclosure.
The #0694 - (#5094 Equivalent) is a prerequisite.
Included with the bottom enclosure is one JTAG cable and one VPD-S cable,
required to attach the bottom enclosure to the system unit. Also included is the
#9887 Base HSL-2 Bus Adapter and #9844 Base PCI IOP.
The #8094 also supports up to four removable media devices (internal tape,
CD-ROM, and DVD). These removable media devices are supported by the two
#2757 PCI-X Ultra RAID Disk Controller, #4748/#4778 PCI RAID Disk Unit
Controller, or #9778 Base PCI RAID Disk Unit Controller that support the first
group of 15 disk units in each enclosure.
The two enclosures in the #8094 are separately attached to the system unit via
HSL cables as though they were a stand-alone #9094 and #5094. They are also
treated as separate units for HSL loop plugging and configuration rules and
recommendations. As such, the bottom enclosure must be attached to the
system unit's first HSL loop.
