Dell PowerScale Prerequisites


Last Updated16 February 2024
  1. OneFS Version Requirements:

    1. For SMB workloads using CEE and RabbitMQ, the minimum required version of OneFS is v8.1.0.x.

    2. For SMB workloads using syslogthe minimum required version of OneFS is v9.5.0.x.  PeerSync is not supported for SMB workloads using syslog.

    3. For NFS workloads using syslogthe minimum required version of OneFS is v9.5.0.x.  PeerSync is not supported for NFS workloads.  CEE and RabbitMQ are not supported for NFS workloads.

  2. Any server that will be interfacing with a PowerScale cluster through a Peer Agent or PeerSync must reside within the same domain, share the same network segment, and belong to the same subnet as the cluster.  Specifically, this connection should be established on OneFS's "external" network, not the internal one.  Additionally, the network connection between OneFS and the Agent or PeerSync must operate at speeds of at least 1 Gbit/sec with sub-millisecond latency.

  3. The system clocks of both the PowerScale cluster as well as the Peer Agent or PeerSync server must be synchronized with each other.

  4. Server OS Version Requirements:
    1. For SMB workloads, the minimum version of Windows required for PowerScale support with the Peer Agent or PeerSync is Windows Server 2016.
    2. For NFS workloads, the Peer Agent must be installed on Ubuntu Server 22.04 operating system or later, or Red Hat Enterprise Linux v8.8 or later.  PeerSync is not supported for NFS workloads.

  5. The server hosting the Peer Agent or PeerSync should not run any other products based on the Common Event Enabler (CEE) framework or syslog from Peer Software or any other vendor.  In addition, no other Peer Software products can be run on this server (such as Peer Management Center or Peer Management Broker).

  6. Messaging Infrastructure Restrictions:

    1. For environments using CEE and RabbitMQ, no other CEE-based applications can utilize the CEE framework on the PowerScale cluster. This restriction does not apply to environments using syslog.
    2. For environments using syslog, any other audit vendors utilizing syslog with OneFS must employ TLS for secure communication.

  7. Authentication Requirement for OneFS v9.2 and later:  Basic Authentication must be enabled on the cluster. To do so, run the following console/SSH command:

    CODE
    isi_gconfig -t web-config auth_basic=true
  8. When connecting a Peer Agent or PeerSync to an access zone other than the default System zone, each node in the cluster must possess an accessible IP address within the IP range associated with the intended access zone.

  9. Privileges and Permissions for SMB Workloads:
    1. The service account for Peer Agent or PeerSync must have local administrator privileges on the Windows Server where the Peer Agent or PeerSync will be hosted.

    2. The service account for Peer Agent or PeerSync must be granted root access to all PowerScale SMB shares, both source and target, that the Peer Agent or PeerSync will connect to.
      To add a new account permission with root access to a share, run the following console/SSH command:

      CODE
      isi smb shares permission create <Share Name> <User Name @ Domain Name> --run-as-root

      To change an existing account permission on a share to root access, run the following console/SSH command:

      CODE
      isi smb shares permission modify <Share Name> <User Name @ Domain Name> --run-as-root
    3. The service account for Peer Agent or PeerSync must be included as a local administrator on the PowerScale cluster.
      To add an account to the local administrators group on the cluster, run the following console/SSH command:

      CODE
      isi auth groups modify --group=administrators --add-user=<User Domain>\\<User name>
  10. Privileges and Permissions for NFS Workloads: The Peer Agent server IP needs to be granted read/write and root access to the exports that this Agent will be monitoring.

  11. API Account Requirements:  To connect a Peer Agent or PeerSync to an access zone other than the default System zone, an API user account in OneFS is necessary. This API account must have ZoneAdmin privileges within the intended access zone. It's essential to note that the default root and admin accounts are not automatically granted these privileges when an access zone is created.

    To grant ZoneAdmin privileges to a user within a specific access zone, run the following console/ssh command:

    CODE
    isi auth roles modify ZoneAdmin --zone <Zone Name>--add-user=<API User Name>
  12. DNS must be able to resolve the Fully Qualified Domain Name (FQDN) of the server that will host Peer Agent or PeerSync.  Both forward and reverse lookups must successfully resolve.

  13. No firewalls (software or hardware) should be enabled between the server hosting Peer Agent or PeerSync and the PowerScale cluster.

Known Limitations

  • When using PowerScale OneFS v9.5+ with syslog, MED pattern matching is not fully functional due to a limitation in OneFS.  We are currently investigating this with Dell.
