BullSequana X1000 compute blade

There are two types of compute cabinets:
► The base compute cabinet provides liquid cooling to the compute blades it houses and also to the switch cabinet.

► The extension compute cabinet is optional and has its own cooling sub-system.

Three types of interfaces connect the compute and switch cabinets together:
► Liquid interface with two flexible pipes from Base compute cabinet hydraulic chassis to switch cabinet manifolds.
► Interconnect interface: each node is connected through one or two interconnect links, one per NIC.
► Management interface for all management controllers in the compute cabinet (PMC, BMC, HMC): one 1Gb/s Ethernet link per node plus 4 sidebands signals for platform management.

The compute nodes are connected to the switch cabinet (L1 switches) via 12 copper cable octopuses named:
► Sideplane Octopus Double for 2 NICs per node,
► Sideplane Octopus Single for 1 NIC per node.

Each BullSequana X1000 compute cabinet houses 48 horizontal compute blades, with the associated power modules at the top of the cabinet and the redundant hydraulic modules for cooling at the bottom of the cabinet.

24 blades are mounted on the front side of the cabinet, while the 24 other blades are mounted on the rear side.
Each 1U blade contains three compute nodes, except for GPU-based blades which contain one node.

Each cell can therefore contain up to:
► 288 dual-socket Intel® Xeon® nodes OR,
► 288 single-socket Intel® Xeon Phi™ nodes OR,
