66 IBM NeXtScale System Planning and Implementation Guide
The nx360 M4 architecture contains the following components:
Two 2011-pin, Socket R (LGA-2011) processor sockets
Intel C602J Platform Controller Hub (PCH)
Four memory channels per socket
One DIMM per memory channel (DPC)
Eight DDR3 DIMM sockets (when only one processor is installed, only four
DIMM sockets can be used)
Support for UDIMMs and RDIMMs
A PCI Express 3.0 x8 slot for Mezzanine card connection that connects to
CPU 1
A PCI Express 3.0 x24 slot for PCIe riser cage that provides a
full-height/half-length (FHHL) slot that connects to CPU 1
A PCI Express 3.0 x16 slot that is connected to CPU 2 (for use with attached
trays)
Dual-port integrated 1 Gb controller
An Integrated Management Module v2 (IMMv2) for remote server
Note: Although the Socket R (LGA-2011) processor socket on the nx360 M4
physically fits Xeon E5-2600 series and Xeon E5-2600 v2 series processor,
only the latter are supported as processor options for this platform.
