The two processors on each node in an IP125 blade maintain an interactive communication link
using the Intel QuickPath Interconnect (QPI) technology. This high-speed interconnect
technology provides data transfers between the on-board processors. See the section “QuickPath
Interconnect Features” on page 28 for an overview of the link functionality and bandwidth
capability.
The IP125 compute blade cannot be plugged into and cannot be used in “previous generation” SGI
ICE X, Altix ICE 8200 or 8400 series blade enclosures. Certain types of multi-generational system
interconnects can be made through the InfiniBand fabric level. Check with your SGI service or
sales representative for additional information on these topics.
IP139 Blade Architecture Overview
The IP139 compute blade contains two 2-socket nodes. The IP139 blade architecture is described
in more detail in the following paragraphs.
The compute blade contains the processors, memory, and uses two of the following fourteen-data
rate (FDR) InfiniBand embedded HCAs:
•
Single-port IB HCA mezzanine cards (one per dual-socket node board)
Each of the two physical boards within the IP139 blade is a (logically independent) two-processor
compute node equipped with eight DIMM slots. Features of the IP139 blade include:
•
Four Intel processors total within each blade
•
The four processors are cooled with liquid “Cold Sink” technology
•
Each processor socket supports four DDR4 memory RDIMMs at up to 2133 MT/s (sixteen
memory DIMM slots total per IP139 blade)
•
Two dual-socket node boards are always installed in each IP139 blade
•
Each blade has two baseboard management controllers (BMCs) - one BMC per node
•
The blade can be fitted with optional expansion kits that support:
–
Up to eight SATA 2.5-inch SSD or HDD (scratch/swap) drives - (note that you cannot
mix SSD and HDD drive types on the same blade)
–
Up to four full-height full-width PCIe cards
–
Up to four liquid-cooled accelerator cards
