# Setting Up the Hardware for Commvault Grid Reference Architecture

Review the hardware requirements needed for the installation of Reference Architecture.

1. Confirm that the purchased server hardware conforms to the Commvault Grid Reference Architecture validated Bill-of-Materials (BOM).

   For more information on the BOM needed for your server model, refer to the linked documents available in Design Specifications for Commvault Grid Reference Architecture.

2. Confirm that the initial hardware setup is complete, which includes the following:

   - Console access

   - Mirrored OS disks except on N4 Reference Architecture nodes

     Only Hardware RAID is supported. Software RAID, such as VROC, are not supported.

   - Setting HDDs in pass-through/JBOD mode

   Make sure that the hardware is functioning properly, including the following:

   - Power supply

   - Fans

   - No failed hard drives

   Depending on your network topology, set up the network as described in the Network Requirements section of the selected topology.

3. Determine if SAN/FC connectivity is required.

   Note

   - This requires the purchase of FC HBA for all except Cisco UCS servers.

   - Dell R740XD2 has limited PCIe slots and requires adjustments to the design to accommodate an FC HBA.

4. For Cisco UCS Servers, verify the isco firmware version.

   Note

   Cisco firmware revision 4.0(4) or higher is required with Commvault Grid Reference Architecture.

   If using Cisco UCS server nodes, determine if it is UCS Managed (includes fabric-interconnects) or unmanaged (without interconnects).

5. Hardware vendors support both UEFI and Legacy boot modes. Only UEFI boot mode is supported for installing Commvault Grid Reference Architecture.
