Prerequisites

The following prerequisites must be met before deploying BCM:

• The cluster administrator has access to the BCM installation media, a valid license, and a product key.

• All hardware is installed and functional.

• All firmware is updated to recommended versions.

• All BIOS/UEFI firmware settings are properly configured.

• For High Availability:

  • A secondary head node, identical in hardware to the primary head node, is available and ready for configuration.

  • An NFS share is created and fully accessible from the cluster.

  • The network is configured in accordance with the Networking Configuration & Logical Architecture Guide for Enterprise RAs.

Figure 1 Diagram showing an example of the BCM head nodes network connections.

Table describing the interfaces as shown in the diagram.

Port	Description	Network
IPMI	Server Management Interface	Out Of Band
eth0	Integrated NIC 1	High Availability Failover Network. A direct connection between the primary and secondary head nodes.
eth1	Integrated NIC 2	N/A
DPU BMC	DPU Management Interface	Out Of Band
eth2	DPU Network Interface 1	North-South
eth3	DPU Network Interface 2	North-South

Note

For High Availability, it is highly recommended that the NICs of both head nodes be directly connected. If a direct connection is not feasible, a dedicated VLAN should be used.
