IP131 Blade Architecture Overview

32
An enhanced and updated version of the SGI ICE X compute blade is used in IP131-based ICE X
systems. One dual-socket node is accommodated on each IP131 blade assembly. The IP131 blade
architecture is described in the following paragraphs:
The compute blade contains the processors, memory, and one of the following fourteen-data rate
(FDR) InfiniBand embedded HCA selections:
• One single-port IB HCA
• One dual-port IB HCA
• Two HCAs each with a single-port IB connector
The node board in an IP131 blade is configured with two Intel E5 2600 v3 processors.
Processor core counts will differ on individual blades based on processing requirements. Check
with your SGI sales representative for processor core counts that meet your compute needs.
A maximum of 16 DDR4 memory DIMMs are supported per compute blade (8 DIMMs per
socket).
The two processors on the IP131 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 34 for an overview of the link functionality and bandwidth capability. Note that the IP131
blade can optionally support one or two native "on-board" 2.5-inch SATA hard disk or SSD drive
options for local swap/scratch usage.
The IP131 node board uses traditional air-cooled heat sinks and works in an air-cooled
environment. The IP131 compute blade cannot be plugged into and cannot be used in "previous
generation" SGI Altix ICE 8200 or 8400 series blade enclosures.
Multi-generational system interconnects can be made through the InfiniBand fabric level.
Note that usage in third-party or non SGI ICE X racks may be restricted due to thermal
requirements.
Check with your SGI service or sales representative for additional information on these topics.
