This topic describes how to create a Super Computing Cluster (SCC) instance.

Background information

This topic describes the configuration items you must pay attention to when you create an SCC instance. For more information about other general configuration items, see Create an instance by using the wizard.

To use remote direct memory access (RDMA), HPC schedulers, and cluster scaling services, log on to the E-HPC console, create an SCC cluster, and create an SCC instance. For more information, see Create an E-HPC cluster.


  1. Log on to the ECS console.
  2. In the left-side navigation pane, choose Instances & Images > Instances.
  3. Click Create Instance.
  4. Complete basic configurations. Click Next: Networking.
    When you configure parameters, note that:
    • Region: Select the region and zone in which SCC instance families are available based on the Regions and zones table. Note that the purchase page displays the latest region and zone information, which may differ from information provided in this topic.
      Instance familyRegions and zones
      • China (Hangzhou) Zone H
      • China (Shanghai) Zone D and Zone B
      • China (Qingdao) Zone C
      • China (Zhangjiakou) Zone A
      • China (Hangzhou) Zone H
      • China (Shanghai) Zone B
      • China (Qingdao) Zone C
      • China (Shanghai) Zone G
      • China (Zhangjiakou) Zone A

      You can go to the ECS Instance Types Available for Each Region page to view the instance types available in each region.

      Note If you can view subscription resources but not pay-as-you-go resources when you purchase an instance, access the FAQ, as instructed in Instance FAQ.
    • Instance Type: Select Super Computing Cluster. Currently, CPU-based instance families scch5 and sccg5 and GPU-based instance family sccgn6 are available. After selecting the SCC instance type, you must specify the SCC name and description as required.
    • Image: Select Public Image. Currently, only the custom Linux CentOS 7.5 image for SCC is supported.
      Note The customized image supports the RDMA over Converged Ethernet (RoCE)-compliant driver and OpenFabrics Enterprise Distribution (OFED) stack. You can use SCC RDMA through the IB Verbs API and manage RDMA communication through the MPI.
    • Storage: A maximum of 16 data disks can be attached. You can add a data disk when you create an SCC instance or attach an instance after the instance is created. For more information, see Create a disk and Attach a data disk.
  5. Complete networking configurations. Click Next: System Configurations (Optional).
    Only the network type of VPC is supported.
  6. Complete system configurations. Click Next: Grouping (Optional).
  7. Complete grouping configurations. Click Next: Preview.
  8. Confirm the order. Click Create Order.
