Add disk storage in an Oracle Database Appliance X8-2-HA storage shelf.

The Oracle Database Appliance X8-2-HA storage shelf partially-populated base configuration supports storage expansion with either 7.68 TB SSDs (available in six-packs) or 14 TB HDDs (available in an eighteen-pack). Depending on your initial base storage shelf configuration, there can be up to eighteen expansion slots. These slots are labeled 6-23 as seen from the front of the system (callouts 6 through 23 in the following illustration).

Description of the illustration gxxxx-x8-2ha_optional_shelf_drives_top.jpg

• If your system has Oracle Database Appliance X8-2-HA software release 18.7, 19.4 or 19.5, all storage must be added BEFORE you initially power-on the system and install system software. Once the system is provisioned and running you cannot add storage.

  If your system is running Oracle Database Appliance release 18.8, 19.6 or later version:

  • For a high performance shelf, you can add up to eighteen 7.68 TB SSDs (available in six-packs). You can add storage with the system running and use the appliance CLI software commands to expand the storage configuration.

  • For a high capacity shelf, you can add eighteen 14 TB HDDs (available in an eighteen-pack). You must power off the appliance, add storage, then re-image and redeploy the appliance software. This is required to reconfigure the appliance from the default high performance mode to high capacity mode.

• Expanding the base configuration storage shelf with 7.68 TB SSDs for high performance. The base configuration has slots 0-5 with 7.68 TB drives for DATA/RECO. Expansion SSDs are available in six-packs and are populated in shelf storage slots from the bottom up to also be used for DATA/RECO, as follows:

  • The first six expansion drives go into slots 6-11.
  • The second six expansion drives go into slots 12-17.
  • The third six expansion drives go into slots 18-23.

  The following illustration shows the expanded drive configuration for 7.68 TB SSDs.

  
  
  Description of the illustration oda_x8-2-ha_shelf_ssds.jpg
  

• Expanding the base configuration storage shelf with 14 TB HDDs for high capacity. When expanding the storage shelf with HDDs, the base configurations SSDs will be used for FLASH and the HDDs will be used for DATA/RECO.
