Compute-only and compute-storage server model servers

The available compute-only and compute-storage server model servers are 9155-C01, 9155-C05, 9155-C10, and 9155-C14. The 9155-C01, 9155-C05, 9155-C10 (32 core node), and 9155-C14 (64 core node) are compute-storage servers.

You can have either six model C10 nodes with storage or model C14 nodes with storage as a minimum configuration. Each of these servers have a minimum of two storage drives that can be increased up to a maximum of ten storage drives on each server.

It is possible to expand IBM Fusion HCI System beyond the minimum six servers with combinations of models C05, C10, and C14.
Important: In the rack model that supports 9155-C01 and 9155-C05, you can include compute-only (C10) servers on need basis. To include C10 server (compute-only), contact IBM Support for upgrade steps.

In the rack model that supports 9155-C10 and 9155-C14, you cannot add 9155-C01 and 9155-C05.

Servers can be added to a maximum of 16 for both racks. If a client chooses to have only one GPU server, then they can have 15 compute-storage servers. Each of the servers added to IBM Fusion HCI System is also added to the storage cluster, increasing the total storage capacity. The servers are also combined into a Red Hat® OpenShift® Container Platform. All applications that run on IBM Fusion HCI System are deployed and run within the OpenShift cluster.
