Chapter 3. IBM System x3850 X5 and x3950 X5 73
Figure 3-15 QPI links for a 2-node x3850 X5
QPI-based scaling is managed primarily through the Unified Extensible Firmware Interface
(UEFI) firmware of the x3850 X5.
For the 2-node x3850 X5 scaled through the QPI ports, when those cables are connected, the
two nodes act as one system until the cables are physically disconnected.
Firmware levels: It is important to ensure that both of the x3850 X5 servers have the
identical UEFI, integrated management module (IMM), and Field-Programmable Gate
Array (FPGA) levels before scaling. If they are not at the same levels, unexpected issues
occur and the server might not boot. See 9.10, “Firmware update tools and methods” on
page 509 for ways to check and update the firmware.
Partitioning: The x3850 X5 currently does not support partitioning.
