Although the processor is an important component in servers, many elements and facilities
have to be balanced across a server to deliver maximum throughput. As with previous
generations of systems based on POWER processors, the design philosophy for POWER7
processor-based systems is one of system-wide balance in which the POWER7 processor
plays an important role.

plays an important role.
Each POWER7 processor has two integrated memory controllers in the chip. Industry
standard DDR3 Registered DIMM (RDIMM) technology is used to increase reliability, speed,
and density of memory subsystems. The functional minimum memory configuration for the
machine is 4GB (2x2GB) but that is not sufficient for reasonable production use of the
machine. It is recommended for the IBM Flex System p460 Compute Node a minimum of
32GB of memory, with 32 x 16 GB DIMMs the maximum memory configurable is 512 GB.

The p460 has an onboard SAS controller that can manage up to two, non-hot-pluggable
internal drives. Even though the p460 is a full-wide server, it has the same storage options as
the p260 and the p24L.
internal drives. Even though the p460 is a full-wide server, it has the same storage options as
the p260 and the p24L.
The type of local drives used impacts the form factor of your memory DIMMs. If HDDs are
chosen, then only very-low-profile (VLP) DIMMs can be used because of internal spacing.
There is not enough room for the 2.5-inch drives to be used with low-profile (LP) DIMMs
(currently the 2 GB and 16 GB sizes). Verify your memory choice to make sure it is
compatible with the local storage configuration. The use of SSDs does not have the same
limitation, and LP DIMMs can be used with SSDs.

The p460 System Management is the same as the p260 and p24L POWER compute nodes.
I/O adapter slots
The networking subsystem of the IBM Flex System Enterprise Chassis has been designed to
provide increased bandwidth and flexibility. The new design also allows for more ports on the
available expansion adapters, which will allow for greater flexibility and efficiency with your
system’s design.

There are four I/O adapter slots on the IBM Flex System p460 Compute Node. The I/O
adapters for the p460 have their own connector that plugs into the IBM Flex System
Enterprise Chassis midplane. There is no onboard network capability in the Power Systems
compute nodes other than the Flexible Service Processor (FSP) NIC interface.

The I/O is controlled by four P7-IOC I/O controller hub chips. This provides additional
flexibility when assigning resources within Virtual I/O Server (VIOS) to specific Virtual
Machine/LPARs.

1.5 I/O Modules
The Enterprise Chassis can accommodate a total of four I/O modules which are installed in
vertical orientation into the rear of the chassis, as shown in Figure 1-13 on page 24 where the
four modules at the back of the chassis with the bays numbered. In addition to the two types
of switches listed in Table 1-1 on page 6, there are alternative I/O modules that provide
external connectivity, as well as connecting internally to each of the nodes within the chassis.
They can be either Switch or Pass through modules with a potential to support other types in
the future. These models can be ordered in 'build to order' IBM Flex Systems solutions.
