System Requirements for OpenStack

Commvault  provides support for the following OpenStack distributions:

  • Red Hat Enterprise Linux OpenStack Platform (RHEL-OP) with the following versions:  Kilo (11), Liberty (12), Mitaka (13), Newton (14)
  • Mirantis with the following versions: Kilo (11), Liberty (12), Mitaka (13), Newton (14)
  • HPE Helion OpenStack 4.0.1 with the following version: Mitaka (13)

When creating a virtualization client, if there are multiple endpoints for the keystone URL, use the keystone URL for the public endpoint.

Virtual Server Agent (Proxy) Requirements

The Virtual Server Agent can be deployed on a Windows or Linux instance in the OpenStack environment.

Only instances that have the VSA installed can act as VSA proxies to perform backups and restores.

At least one proxy is needed for each region. You can deploy additional VSA proxies as needed for load balancing.

The following operating systems are supported for VSA proxies:

  • Microsoft Windows Server 2016
  • Microsoft Windows Server 2012 R2
  • Microsoft Windows Server 2008 R2
  • CentOS 7
  • RHEL 7.2, 7.3

Note: Linux proxies must have the psmisc and lvm2 packages installed.

The Virtual Server Agent should be installed on instances that meet the following requirements:

  • Minimum of 100 GB disk space recommended
  • Minimum of 4 GB RAM required beyond the requirements of the operating system and running applications

For Windows proxies, VirtIO version 62.73.104.11800 is supported as a driver for OpenStack backup and restore operations.

Note: To use a Red Hat 7 proxy, use the following commands to disable lvmetad. Having lvmetad running interferes with HotAdd operations during backup and recovery.

  1. Disable and stop the lvm2-lvmetad service by running the following commands:

    systemctl disable lvm2-lvmetad
    systemctl stop lvm2-lvmetad

  2. Disable and stop the lvm2-lvmetad.socket service by running the following commands:

    systemctl disable lvm2-lvmetad.socket
    systemctl stop lvm2-lvmetad.socket

  3. Disable lvmetad in the LVM config file by running the following command:

    edit /etc/lvm/lvm.conf to include use_lvmetad = 0

MediaAgent Requirements

The following packages must be installed on MediaAgents that are used for guest file browse and restore operations on Glance images:

  • QEMU disk image utility (qemu-img)
  • libguestfs
  • libguestfs-tools
  • Logical Volume Management (lvm)

Port Requirements

  • The security group associated with the proxy instance should permit all incoming and outgoing TCP traffic.
  • If unrestricted access cannot be set up, configure a one-way Commvault firewall between the CommServe host or MediaAgent and the VSA proxy instance. With this firewall configuration, you can restrict communication to a single TCP port (typically port 8400).
  • When using the RHEL-OP distribution or in any OpenStack environment that includes a firewall, ensure that CVD port 8400 is configured to accept incoming traffic from Commvault.
