Your slot configuration must also allow for the disk I/O adapters you need to support the cluster’s shared disk (volume group) configuration. If you intend to use disk mirroring for shared volume groups, which is strongly recommended, then you will need to use slots for additional disk I/O adapters, providing I/O adapter redundancy across separate buses.
The following table tells you the number of additional adapters you can put into the different RS/6000 models. Ethernet environments can sometimes make use of the integrated ethernet port provided by some models. No such feature is available for
