7 Expanding a Recovery Appliance Rack with Additional Storage Servers

The Oracle Zero Data Loss Recovery Appliance racks have a flexible configuration that allows a minimum of three storage servers, and can be extended based on version.

• RA23: a total of 17 storage servers. Usable capacity normal redundancy, 92 TB per storage server, or minimum (3 storage servers) 274 TB and full rack total 1,564 TB. The usable capacity under high redundancy is 60 TB per storage server.
• RA21: a total of 18 storage servers. Usable capacity normal redundancy 70 TB per storage server, or minimum (3 storage servers) 207 TB and full rack total 1,260 TB. The usable capacity under high redundancy is 44 TB per storage server.
• X8M, and X8 through X5: a total of 18 storage servers.
• X4: a total of 14 storage servers.

All Recovery Appliance racks have two compute servers, regardless of the number of storage servers.

Note:

Older storage servers cannot be removed and replaced with newer storage servers while keeping existing Recovery Appliance backups online. If such an exchange is done, a re-image of the Recovery Appliance is required.
