Compute-only and compute-storage server model servers

Dell hardware offers two server models to support various workload requirements: the 9155-D10 and 9155-D14.

Compute only servers

Compute-only nodes are designed for applications that require high processing power and can utilize external storage solutions. These nodes are ideal for workloads that depends on shared storage or have low storage requirements. The available compute only nodes are 9155-D10 and 9155-D14.

Compute-storage servers

Compute-storage nodes, on the other hand, combine processing power with integrated storage, providing a self-contained solution for applications that require both compute and storage resources. This configuration is suitable for workloads that require low-latency access to data or have high storage demands. The available compute-storage nodes are 9155-D10 and 9155-D14.
Important: Each 9155-D10 and 9155-D14 server can have a minimum of two storage drives that can be increased up to a maximum of ten storage drives.

You can have either six 9155-D10 or 9155-D14 nodes with storage as a minimum configuration, and also you can expand your IBM Fusion HCI beyond the minimum six servers by adding combinations of models D10 and D14. Each rack can support up to 16 servers.

Hardware configuration for 9155-D10 (32 core compute-only or compute-storage node)
  • Dell R660XL
  • 2x 16-core Intel Xeon 4th Gen Gold 6426Y 2.5GHz 185W processors
  • 256GB RAM (16x 16GB DDR5 DIMMs)
  • Optional memory upgrade to 512GB (32x 16GB DIMMs)
  • 0-10x 7.68TB or 3.84TB PCIe NVMe drives

  • 1x Intel I350 1GbE RJ45 4-port OCP Ethernet Adapter
  • 2x 960GB M.2 NVMe OS drives (RAID 1)
Hardware configuration for 9155-D14 (64 core compute-only or compute-storage node)
  • Dell R660XL
  • 2x 32-core Intel Xeon 4th Gen Gold 6438N 2.0GHz 205W processors
  • 1024GB RAM (16x 64GB DDR5 DIMMs)
  • Optional memory upgrade to 2048 GB (32x 64GB DIMMs)
  • 0-10x 7.68TB or 3.84TB PCIe Gen 5 NVMe drives
  • 1x NVIDIA ConnectX-6 DX dual-port 100GbE PCIe NIC
  • 1x Intel I350 1GbE RJ45 4-port OCP Ethernet Adapter
  • 2x 960GB M.2 NVMe OS drives (RAID 1)
Important: You cannot mix and match different drive capacities within the same rack. You must choose one capacity and use it consistently throughout.

As you add servers to the system, they are also added to the storage cluster, increasing the total storage capacity. All added servers are combined into a Red Hat® OpenShift® Container Platform. This means that all applications running on IBM Fusion HCI System are deployed and run within the OpenShift cluster.
