5486m870.fm Draft Document for Review October 18, 2004226 IBM Eserver i5 and iSeries System Handbook#5107 30 Disk ExpansionThe #5107 is a disk unit expansion enclosure feature for the #9094 Base PCI I/OEnclosure. The #5107 includes two 15 disk unit enclosures, one 840-watt powersupply, backplanes, and cables.A #2757 PCI-X Ultra RAID Disk Controller or #4748/#4778 PCI RAID Disk UnitController or #5703 PCI-X RAID Disk Unit Controller is required to support diskunits in each of the two disk unit enclosures included with #5107. Each group of15 disk units is further divided into three groups of five disk units with each groupof five disk units supported on a separate SCSI bus. A minimum of two disk unitcontrollers and a maximum of six are required to support 30 disk units.#8094 Optional 1.8 M I/O RackThe #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 22PCI IOAs, and up to three additional removable media units. A #8094 is a 1.8 Mrack with two enclosures. The bottom enclosure is a #9094 Base PCI I/O Enclosure with side coversand casters removed and a #5107 30 Disk Expansion included in the base(no feature code required). The #5114 Dual Line Cords - Tower is amandatory feature for the #9094. The top enclosure is a #5094 PCI-X Expansion Tower with side covers andcasters removed, and a #5108 30-Disk Expansion Feature (no feature coderequired) included in the base. The #5115 Dual Line Cords - Tower featurecode 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 UnitController, or #9778 Base PCI RAID Disk Unit Controller that support the firstgroup of 15 disk units in each enclosure.The two enclosures in the #8094 are separately attached to the system unit viaHSL cables as though they were a stand-alone #9094 and #5094. They are alsotreated as separate units for HSL loop plugging and configuration rules andrecommendations. As such, the bottom enclosure must be attached to thesystem unit's first HSL loop.
