74 IBM Flex System p260 and p460 Planning and Implementation Guide
The overall system architecture for the p260 and p24L is shown in Figure 4-9.
Figure 4-9 IBM Flex System p260 Compute Node block diagram
In this diagram, you can see the two processor slots, with eight memory slots for
each processor. Each processor is connected to a P7IOC I/O hub, which
connects to the I/O subsystem (I/O adapters and local storage). At the bottom,
you can see a representation of the service processor (FSP) architecture.
The IBM Flex System p460 Compute Node shares many of the same
components as the IBM Flex System p260 Compute Node. The IBM Flex System
p460 Compute Node is a full-wide node, and adds additional processors and
memory along with two more adapter slots. It has the same local storage options
as the IBM Flex System p260 Compute Node.
