Solution architecture

  • A recommended base configuration for infrastructure servers is:

    • Dell PowerEdge R660 server
    • Intel Xeon Gold 6430 processor
    • 256 GB of RAM (16 x 16 GB 4800 MTps DIMMs)
    • PERC H355 RAID controller
    • 2 x 480 GB Mixed-Use SATA SSD RAID 1
    • Dell iDRAC Enterprise
    • 2 x 1100 W power supply units (PSUs)
    • NVIDIA ConnectX-7 InfiniBand HCA (optional)

    The PowerEdge R660 server is suited for this role. Typical HPC clusters only use a few infrastructure servers; therefore, density is not a priority, but manageability is important. The Intel Xeon Gold 6430 processor, with 32 cores per socket, is recommended for this role. If the infrastructure server is used for CPU-intensive tasks, such as compiling software or processing data, a more capable processor might be appropriate. Configuring the server with 256 GB of RAM provided by 16 16 GB DIMMs provides sufficient memory capacity, with minimal cost per GB, while also providing good memory bandwidth. These servers are not expected to perform considerable I/O, so mixed-use SATA SSDs configured with RAID 1 are sufficient for the operating system. For most systems, NDR InfiniBand is the data interconnect of choice. It provides a high-throughput, low-latency fabric for node-to-node communications or to access file storage. Including an InfiniBand HCA in the infrastructure server is optional depending on the system design.
