Notes:
400 Gb/s IB network interface cards (NIC) are installed on the right side of the network (red). However, a pair of two nodes shares one NIC. Hence, per node the effective bandwidth is 200 Gbit/s.0
6 storage gateways (Lenovo ThinkSystem SR630 V2) provide access from the “Spine Stor” top-level switches to the “storage scale” File Systems (/home, /scratch, /sw).
2+6 gateway servers (green GPU + red Genoa side, respectively) provide access to the OPA network of the CLX partition.
Mellanox (acquired by Nvidia) manufactures InfiniBand host bus adapters and network switches.
