IP Address Requirements for ZDLRA Rack

The Recovery Appliance requires a dedicated allocation of host names and IP addresses. The number of required IP addresses primarily depends on the size of the system.

The detailed network configuration, including host names and IP addresses, is generated from information supplied to Oracle Exadata Deployment Assistant (OEDA).

You should configure the IP addresses in your existing networks after you run OEDA. All IP addresses in the configuration file must be unassigned at the time of initial configuration. In addition, all IP addresses must be statically-assigned IP addresses, not dynamically-assigned (DHCP) addresses.

All RDMA Network Fabric IP addresses must be in the same subnet, with a minimum subnet mask of 255.255.240.0 (or /20). The subnet mask chosen should be wide enough to accommodate possible future expansion of the Recovery Appliance and the internal network.

You can use the information in the following sections to calculate the IP address requirement for Recovery Appliance. However, ensure that you use the configuration information generated in OEDA as your authoritative guide.

Rack-Level IP Address Requirements

The following table outlines the rack-level IP address requirements for Recovery Appliance. These addresses are required regardless of the configuration options that are selected for the system.

Network	IP Address Requirements
Administration Network	1 IP address for the administration network interface on each compute server or storage server. 1 IP address for the ILOM network interface on each database server or storage server. 1 IP address for the management interface on each RDMA Network Fabric switch. 1 IP address for the management interface on the Management Network Switch switch. 1 IP address for the management interface in each power distribution unit (PDU).
RDMA Network Fabric (Private Network)	2 IP addresses for each database server or storage server.
