Chapter 2. IBM iSeries SB2 and SB3 models 33
Main storage
There are no memory features on Models SB2 and SB3.
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 page224, for an introduction to PCI.
#9943
Base IOP
#9943 Base PCI IOP
The #9943 (CCIN 2843) is included as the base IOP for Models SB2 and SB3. See the #2843 description for details and
cards supported.
#2790
#2791
#2799
#2790 PCI Integrated Netfinity Server or #2791/#2799 P CI Integrated xSeries Serve r
The #2790 PCI Integrated Netfinity Server contains a 700 MHz processor. The #2791 PCI Integrated xSeries Server
contains an 850 MHz processor. The #2799 PCI Integrated xSeries Server contains a 1.0 GHz Intel® Pentium III
processor. Each processor contains four memory slots in the xSeries IOP.
The #2790, #2791, or #2799 is supported in the system tower of the Model SB2 and SB3.
Each main storage slot of the #2790, #2791, or #2799 server can contain either a 128 MB, 256 MB, or 1024 MB xSeries
server main storage card, providing a total server main storage capacity ranging from 128 MB to 4096 MB (4 GB). A
minimum of one main storage card is required on the xSeries IOP. A maximum of 3712 MB of memory is addressable.
The following main storage cards provide memory for the #2790, #2791, or #2799 when installed in a Model SBx system
unit or attachable HSL towers:
#2795 - 128 MB server memory
#2796 - 256 MB server memory
#2797 - 1 GB server memory
The #2790, #2791, or #2799 can support PCI 100/16/4 Mbps Token Ring IOAs, PCI 100/10 Mbps Ethernet IOAs, or PCI
1Gbps Ether net IOAs in any combination. A minimum of one LAN IOA is required. The supported LAN IOA features are:
#2743 1 Gbps PCI Ethernet IOA
#2744 PCI 100 Mbps Token Ring IOA
#2760 PCI 1 Gbps Ethernet UTP Adapter
#4838 PCI 100/10 Mbps Ethernet IOA
An #0223 100 Mbps Token-Ring specify code is required on the Integrated xSeries Server for each #2744 selected to run
on the #2790, #2791, or #2799.
An #0224 100/10 Mbps Ethernet specify code is required on the Integrated xSeries Server for each #4838 selected to run
on the #2790, #2791, or #2799.
One #0225 1 Gbps Ethernet specify code is required on the Integrated xSeries Server for each 1 Gbps Ethernet adapter
selected to run on the 2790, #2791, or #2799.
Up to three IOA LAN features are supported by the #2790, #2791, or #2799, depending on which system or expansion
tower position the #2790, #2791, or #2799 is placed. The #2790, #2791, and #2799 require three PCI card slots. One slot
is consumed. The second slot is unusable. The third slot is reduced to a short card slot which is then used by the first
attached LAN IOA card.
