Generations

Works together

How the HPE Cray XD6500 connects to servers, storage and the network: 4 ways, with the parts and products on each path.

Fibre Channel SANiSCSI and NVMe/TCP over EthernetDirect-attached SASFile storage (NFS and SMB)

Fibre Channel SAN

Match the speed: 16Gb and 32Gb FC HBAs, switches and array ports work together, and each generation also runs one or two speeds below its own (a 32Gb port runs at 16Gb and 8Gb).

Fibre Channel SAN: how it fits together

iSCSI and NVMe/TCP over Ethernet

Keep the speed the same at all three points: a 25GbE server, a 25GbE switch port and a 25GbE array port. Mixed speeds work but the slowest link sets the pace.

Direct-attached SAS

12Gb SAS uses Mini-SAS HD (SFF-8644) connectors; older 6Gb gear uses Mini-SAS (SFF-8088). Adapter cables exist, but the link runs at the slower speed.

File storage (NFS and SMB)

Front-end ports face the clients; back-end ports (on scale-out systems) connect the nodes to each other and need their own switch pair.

FAQ

What cooling infrastructure is required for the Cray XD6500?

The system offers direct-to-chip liquid cooling manifolds as well as heavy-duty high-CFM chassis air cooling options for enterprise data halls.

Which host interconnects are recommended for multi-node clusters?

HPE Slingshot 200Gb/s or 400Gb/s InfiniBand NDR networking cards ensure low latency fabric communication across thousands of nodes.
