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:

  • You can cable together different rack models. For example, you can cable together an X8-2 rack and an X7-2 rack, or X8M with X9M. X8M racks can be combined with X9M and RA21

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

    For X8M and X9M, 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: X8M storage (14 TB); X9M and RA21 have X9 storage (18 TB).

    X8M can be multi-racked with X9M or RA21.

• 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:
