Chapter 4. IBM System x3690 X5 129
The x3690 X5 supports the following configurations:
A single x3690 X5 server with two processor sockets. This configuration is sometimes
referred to as a
single-node server.
A single x3690 X5 server with a single MAX5 memory expansion unit attached. This
configuration is sometimes referred to as a
memory-expanded server.
The MAX5 memory expansion unit permits the x3690 X5 to scale to an additional 32 DDR3
DIMM sockets.
Connecting the single-node x3690 X5 with the MAX5 memory expansion unit uses two QPI
cables, part number 59Y6269, as listed in Table 4-4. Figure 4-12 shows the connectivity.
Figure 4-12 Connecting the MAX5 to a single-node x3690 X5
Connecting the MAX5 to a single-node x3690 X5 requires one IBM MAX5 to x3690 X5 Cable
Kit, which consists of two QPI cables. See Table 4-4.
Table 4-4 Ordering information for the IBM MAX5 to x3690 X5 Cable Kit
Two-node configurations: The 2-node configurations (with and without MAX5) are not
supported.
Number of processors: The MAX5 is supported with either one or two processors
installed in the x3690 X5. However, the recommendation is to have two processors
installed and memory installed in every DIMM socket in the server to maximize
performance.
Part number Feature code Description
59Y6269 7481 IBM MAX5 to x3690 X5 Cable Kit (two cables)
Note: There is no setup on the Integrated Management Module (IMM) for scalability.
Ensure that you have updated all firmware before attaching the MAX5, especially the Field
Programmable Gate Array (FPGA). For more information about updating firmware, see
9.10, “Firmware update tools and methods” on page 509.
