Oracle RMAN Channels

ExaGrid supports Oracle RMAN Channels targeted at multiple NAS shares across multiple appliances with

global deduplication in a scale-out system. RMAN Channels automatically writes “sections” in parallel to all

NAS shares and automatically redirects the next “section” based on available targets. RMAN Channels with

ExaGrid has six major advantages.

1. Oracle database can be up to 2.69PB in size and can be backed up in parallel to a single

ExaGrid scale-out system.

2. The database backup performance is accelerated as the sections are backed up in parallel

across multiple appliances in a scale-out system.

3. The database backup performance is maximized as each new section is automatically sent

to the highest performance availability NAS shares and/or appliance, resulting in the best

possible performance based on NAS share and appliance ingest availability.

4. If any appliance fails, the segments are automatically redirected to the active appliance,

providing for automatic failover.

5. The most recent database is stored in an undeduplicated form in the ExaGrid disk-cache

Landing Zone, allowing for fast restores while still allowing for storage efficiency as all

long-term retention data is stored in deduplicated form. This avoids the lengthy data

rehydration process of inline scale-up appliances that only store deduplicated data.

6. As the database data grows, the backup window stays fixed in length as full appliances are

added into a scale-out system bringing compute with capacity. This eliminates the forklift

upgrades associated with inline scale-up deduplication appliances.
