Prerequisites for Hedvig Storage Clusters

Hedvig Storage Servers

• Hedvig software version 3.9.9.9.
• Hedvig software is supported on CentOS 7.x and RHEL 7.x.

  Install the minimal version (7.7, as of this Hedvig release) of the CentOS on the storage nodes.

• RHEL requires a valid subscription to RHEL server repositories.

MediaAgent / Hedvig Proxy(s)

The MediaAgent software and the proxy must reside on the same computer.

• Commvault V11 with Feature Release 19 (or above).
• Hedvig software version 3.9.9.9
• Hedvig software is supported on CentOS 7.x and RHEL 7.x.

  Install the minimal version (7.7, as of this Hedvig release) of the CentOS on the storage nodes.

• RHEL requires a valid subscription to RHEL server repositories.

Note: Minimum deployment should include 3 nodes for storage access, and at least 2 proxies for fault tolerance.

Hedvig Deployment Server

• An esx/hyperv/kvm for importing the OVA file to create the deployment VM.
• An Ansible Configuration File. There are sample Ansible files in /opt/hedvig/samples on the Hedvig Deployment Server (after extracting hedvig_extract.bin).

  Contact Commvault to get an Ansible Configuration File customized for your environment.

CommServe Version

Commvault V11 with Service Pack 18 and Hot Fix Pack 5 (or a more recent version).

Password Requirements

Root password is required to deploy both the Hedvig Storage nodes and the Hedvig Proxies.

Network Requirements

All the Hedvig Storage Nodes and the MediaAgents / Proxies must have static IP addresses, and the mapping from IP to hostname be updated in /etc/hosts even if DNS resolution is available.

Storage proxies are configured with 2 ethernet interfaces and run as an HA pair (except for storage proxies that are used for object storage). For failover to work correctly, a public VIP address and a private VIP address are required for the ethernet interfaces.
