This paper generally discusses card placement considerations but does not provide detailed
rules. For POWER6 configurations, refer to the following publications available in the IBM
Systems Hardware Information Center under the Power Systems category at:

1.2.4 I/O enclosures attaching using 12x or RIO-2 I/O loop adapters
As described earlier in this chapter, each POWER6 520, 550, or 570 system unit supports
zero, one, or two GX+ adapters for attaching I/O enclosures in addition to any enclosures that
are supported by the system unit’s five I/O expansion slots.
The POWER6 595 supports from one to eight processor books. Each processor book
supports up to four GX+ adapters.
The following technology GX+ adapters are available for attaching I/O enclosures:
► 12X offers the potential of total loop capacity greater than the maximum capacity of RIO-2
technology, and 12X is the implementation from IBM based upon the industry-defined
InfiniBand architecture. 12X means that the I/O data has 12 paths for transmitting and
receiving data. Specific I/O enclosures supporting 12x connections do not support RIO-2
connections.
► RIO-2 is the second generation of RIO I/O enclosure attachment technology. System i
customers are familiar with the HSL name for the same RIO level technology. That is,
RIO-2 and HSL-2 are exactly the same technology. In most cases within this paper, we
use the term RIO-2.
The processor enclosure or processor book contains the appropriate GX+ adapter feature
number, and the loop-attached I/O enclosure adapter must match the host RIO-2 or12x
adapter. I/O enclosures that support IOP cards connect to a system using a RIO-2 adapter.
Several specific feature numbered I/O enclosures use the following terminology:
► I/O drawer
► I/O tower
► I/O expansion unit
When describing the specific feature number in this paper, we use the specific enclosure
name. When discussing supported I/O enclosures generally, we use the term I/O enclosure.
Chapter 4, “Feature descriptions and related information” on page 187 uses the feature
description text from the appropriate IBM Power System model sales manual pages.
In the next two sections, 1.2.5, “Common I/O enclosures from existing System i and System p
configurations that are supported on POWER6” on page 14, and 1.2.6, “Common racks from
System i and System p configurations” on page 17, we place the most commonly configured
System i and System p I/O enclosures and racks in rows that help identify their disk and PCI
card support. Where appropriate, we place both the System i and System p enclosure
descriptions that represent identical or almost identical hardware within the same table row.
