Ceph

ZStack Cloud allows you to store files in Ceph primary storage in the format of blocks. If you add a Ceph primary storage, you need to add a Ceph primary storage, you need to add a Ceph or ImageStore backup storage and configure Ceph distributed storage in advance.

Figure 1. Add Ceph Primary Storage


On the displayed page, set the following parameters:
  • Name: Enter a name for the primary storage.
  • Description: Optional. Enter a description for the primary storage.
  • Type: Select Ceph.
  • Cephx: Choose whether to use keys for authentication.
    Note:
    • By default, the Cephx authentication feature is enabled.
    • If you disable Cephx, the authentication feature is disabled.
    • If storage nodes and compute nodes reside in secure networks, you can disable Cephx to avoid authentication failures.
    • Make sure that the Cephx configuration on Ceph storage is consistent with this configuration. If Cephx is enabled on Ceph storage but disabled on the cloud platform, VM instances may fail to be created.
  • IP Address: Enter the IP address of the Ceph monitor node.
  • SSH Port: Enter the SSH port of the Ceph monitor node. Default: 22.
  • User Name: Enter the username of the Ceph monitor node.

  • Storage Network: Specify a network for the shared storage. You can use the management network.
    Note:
    • If you specify a dedicated storage network, you need to specify the CIDR of the network.
    • You can use the storage network to check the health status of VM instances.
