Chapter 7. IBM iSeries 820, 830, and 840 features and placement 239
#5094
(cont.)
#5094 PCI-X Expansion Tower
PCI IOAs are supported (driven) by the #9844/#9943 Base PCI IOP, #2843/#2844/#2847 PCI IOPs, #2790 PCI Integrated
Netfinity Server, #2791/#2792/#2799 PCI Integrated xSeries Servers or #4710/#9710 Integrated xSeries Servers.
The 45 disk unit positions are in groups of 15. Each group of 15 disk units is further divided into three groups of five disk
units. Each group of five disk units is supported on a separate SCSI (LVD-SCSI) bus from a #2757, #2780, #4748, or #4778
PCI RAID Disk Unit Controller. Each group of 15 disk units requires one #2757, #4748, or #4778 PCI RAID Disk Unit
Controller.
The mounting for the first 15 disk units is included in the #5094 (part of the base tower). The mounting for the next 30 disk
units is optional by ordering feature code #5108 30-Disk Expansion Feature.
The #5094 expansion tower offers additional LPAR configuration flexibility. Instead of the previous maximum number of
three disk controllers supported in a #5094, now up to nine total disk controllers are supported. These can be either OS/400
controlled (maximum of six OS/400 partitions) or Linux controlled. The #5294 is enhanced and now supports a maximum
of 18 disk controllers. The #5703/#0628 disk controller can be used to go beyond the maximum of three, already supported
#2757, #2780, #4748, and #4778 disk controllers.
Each tower must have a minimum of one #2748, #2757, #2780, #4748, or #4778 for each group of 15 disk units in the tower.
Only the #5703/#0628 can be ordered as an extra controller (up to two #5703/#0628s per group of 15 disk units in the same
tower) if #0143 Disk Controller Placement Exception is also ordered. Disk controllers #2748, #2757, #2780, #4748, or
#4778 cannot be ordered as extra controllers if #0143 is also ordered. A maximum of six #5703/#0628s per #5094 tower
are supported
The number of disk units per #2757 and #2780 varies by configuration.
The #5094 PCI-X Expansion Tower supports up to two removable media devices (internal tape or internal CD-ROM or
DVD). These removable media devices are supported by the same #2757, #2780, #4748, or #4778 PCI RAID Disk Unit
Controller which supports the 15 base disk units.
The #5094 is also supported in Linux and AIX partitions with SUSE Linux Enterprise Server 9 for POWER or Red Hat
Enterprise Linux AS for POWER Version 3, and AIX 5L for POWER V5.2.
Minimum operating system level: OS/400 V5R2
#5095 #5095 PCI-X Expansion Tower
The #5095 PCI-X Expansion Tower provides I/O capability for iSeries systems. The #5095 has seven PCI-X IOP/IOA slots.
The #5095 also supports up to 12 disk units.
A #9844 Base PCI IOP is included as base and should be on an initial order for the #5095 PCI-X Expansion Tower.
The #5095 includes a bus adapter to provide the HSL-2 interface to the system. The IBM marketing configurator adds one
of the following to the order:
#6417 HSL-2/RIO-G Bus Adapter
#9876 Base Optical Bus Adapter
#9877 - Base HSL-2 Bus Adapter
A #9877 - Base HSL-2 Bus Adapter is shipped with new orders of a #5094 for Models 820, 830, 840.
#9886 Base Optical Bus Adapter (optical HSL-2)
Specify when attaching to optical HSL-2 ports.
#9887 Base HSL-2 Bus Adapter (default)
Specify when attaching to copper HSL ports.
