7.5 PCI IOP controllers
PCI IOP controllers
PCI Rules PCI cards are subject to plugging rules. PCI Card Placement Rules for the IBM eServer iSeries Server, REDP-3638
describes the configuration and card placement rules that you must understand and follow to develop valid configurations.
Use these IBM Redpapers as guides when configuring IOAs and input/output processors (IOPs) so that the system is sized
to meet client expectations. Refer to 7.1, “PCI card placement for iSeries servers” on page 224, for an introduction to PCI.
Embedded
IOP
Embedded 32 MB Base PCI IOP (CCIN 284C)
The embedded IOP is standard on every Model 820 system tower, and the #5075 PCI Expansion Tower. This IOP is
embedded and, therefore, does not require a PCI card slot. Provides support for maximum of up to four IOAs, including the
#5702 PCI-X Ultra Tape Controller or #9767 Base PCI Disk Unit Controller SCSI IOA, the #9771, #9773, or #9774 PCI
2-Line WAN with integrated modem and the System Console IOA.
See “#2843 PCI IOP” on page 251, for a list of other supported cards.
#9943
Base IOP
#9943 Base PCI IOP
The #9943 Base PCI IOP (CCIN 2843) is included as the base IOP for Model 830 (in the #9074 Base I/O Tower), Model
840 (in either the #9079 Base I/O Tower or the #8079 Optional Base 1.8 M I/O Rack), and in the #5074 PCI Expansion
Tower and #5079 1.8 M I/O Tower.
The #5079, #8079, and #5097 include two base IOPs.
See “#2843 PCI IOP” on page 251, for a list of other supported cards.
#2843
#9943
#2843 PCI IOP
The #2843/#9943 is a PCI I/O processor with 64 MB of memory that drives up to four PCI IOA adapters on the Models 820,
830, 840, #5074 PCI Expansion Tower, #5075 PCI Expansion Tower when attached to the Model 820, and on the
#0578/#5078 PCI Expansion Unit, #0588/#5088 PCI-X Expansion Unit, #5094 PCI-X Expansion Tower, #0595/#5095
PCI-X Expansion Tower, #5294 1.8 m I/O Tower, and the #5079 1.8 M I/O Tower.
The following IOAs are supported (driven) by the embedded PCI IOP on the Model 820 and the #2843/#9943 PCI IOP:
