Part VI Extending Oracle Zero Data Loss Recovery Appliance

You can extend Oracle Zero Data Loss Recovery Appliance either by adding servers to the current configuration or by cabling together multiple racks.

Here are considerations when extending Recovery Appliance racks:

• You can extend Recovery Appliance from a fixed or custom configuration to another configuration by adding storage servers up to the allowed maximum.

• You can cable together multiple Recovery Appliance racks subject to the following:

  • Oracle Zero Data Loss Recovery Appliance RA26-Z can be multi-racked with RA23-Z.

  • Oracle Zero Data Loss Recovery Appliance RA26 can be multi-racked with RA23, RA21 or X8M.

  • Oracle Zero Data Loss Recovery Appliance RA23 can be multi-racked with RA21 or X8M.

    Oracle Zero Data Loss Recovery Appliance X8-2 can be multi-racked with X7-2 and earlier ZDLRA Racks.

  • All racks in the multi-rack configuration must use the same RDMA Network Fabric.

    For X8M and later, all racks must use RoCE Network Fabric.

    For X8 and earlier, all racks must use InfiniBand Network Fabric.

  • The racks can have different storage disk drives:

    • RA26-Z have 26 TB

    • RA26 have 26 TB

    • RA23 have 22 TB

    • RA21 have 18 TB

    • X8M have 14 TB

• Prior to extending a system across multiple racks, you must acquire the appropriate RDMA Network Fabric switches and transceivers.

Multiple Recovery Appliances can run as separate environments while sharing the RDMA Network Fabric. If you are planning to utilize multiple Recovery Appliances in this manner, then note the following:

• Extending a Rack by Adding Another Rack

• Multi-Rack Cabling Tables for Recovery Appliance RA21 and Later Models

• Multi-Rack Cabling Tables for Recovery Appliance X8M Models

• Multi-Rack Cabling Tables for ZDLRA Rack Models with InfiniBand Network Fabric (X2 to X8)
