7.5.1 IOP-less IOAs and placement
Starting in 2006, the System i5 models started supporting IOAs, also referred to as controllers, that can operate with
or without a “controlling IOP.” As a result, there are three “classes” or “types” of IOAs that are supported by:
 IOP controlled IOAs
– Not supported in the POWER6 system unit enclosures
– Supported in an I/O tower or drawer attached to the POWER6 models 9408-M25, 9409-M50, 9117-MMA and
9406-MMA with a RIO-2 loop
 IOP-less
– IOP-less only IOAs, are supported in the POWER6 system unit enclosure and its I/O tower or drawer
pluggable features
– Single mode IOP-less IOAs that are not recognized by IOPs
These IOAs can be placed virtually anywhere relative to installed IOPs without causing problems

Placement considerations (maximums) for the #2844 include:
 The #5790 PCI Expansion Drawer supports two #2844s with blindswap cards. Two #5790s can be placed side by side
in a rack with #7307/#7311 Dual I/O Unit Enclosure
The #2844 supports a maximum of 16 devices.
The #2844 is a Customer Install Feature
