About Managing Storage
You can add storage at any time without shutting down your databases or applications.
Oracle Database Appliance uses raw storage to protect data in the following ways:
-
Flash or Fast Recovery Area (FRA) backup. Flash or fast recovery area is a storage area (directory on disk or Oracle ASM diskgroup) that contains redo logs, control file, archived logs, backup pieces and copies, and flashback logs.
-
Mirroring. Double or triple mirroring provides protection against mechanical issues.
The amount of available storage is determined by the location of the FRA backup (external or internal) and if double or triple mirroring is used.
Oracle Database Appliance uses storage shelves, a base shelf and an optional storage expansion shelf. You can expand the base storage by adding a pack of solid-state drives (SSDs) to fully populate the base storage. You can further expand the storage by adding a second storage shelf. External NFS storage is supported for online backups, data staging, or additional database files.
Note:
The storage expansion shelf is no longer available for Oracle Database Appliance X7-2-HA and other older models. You can repurpose an existing storage expansion shelf from one Oracle Database Appliance system to another.Note:
Oracle recommends that you upgrade your deployment to the latest Oracle Database Appliance software release before adding storage to ensure that your appliance has the latest firmware.When you add storage, Oracle Automatic Storage Management (Oracle ASM) automatically rebalances the data across all of the storage including the new drives. Rebalancing a disk group moves data between disks to ensure that every file is evenly spread across all of the disks in a disk group and all of the disks are evenly filled to the same percentage. Oracle ASM automatically initiates a rebalance after storage configuration changes, such as when you add disks.

Storage Addition Options for Oracle Database Appliance X6-2-HA
Understand the storage configuration options for Oracle Database Appliance X6-2-HA.
Note:
The 3.2 TB and 1.6 TB SSDs are no longer available. You can use the 5-pack of 7.68 TB SSDs for storage expansion. The expansion shelf is also no longer available.Table 10-1 Storage Addition Options for Oracle Database Appliance X6-2-HA
Configuration | Storage Option | Total Storage |
---|---|---|
Base Configuration | Ten (10) 1.6TB SSDs in slots 0 - 9 and four (4) 200GB SSDs in slots 20 - 23 | 200 GB SSDs dedicated for database REDO and 1.6TB SDDs used for DATA. |
Base Shelf Expansion | Additional Ten 7.68 TB SSDs in slots 10 - 19 or
replace all Twenty 7.68 TB SSDs in slots 0 - 19
Order Qty 2 or 4: 7600790: Five-pack of 7.68TB SSD drives |
Power off the appliance and replace any existing 1.6 TB or 3.2 TB SSDs with 7.68 TB SSDs. Perform cleanup, reimage and redeploy the appliance, and restore the database from a backup. If you replace all your existing 1.6 TB or 3.2 TB SSDs with 7.68 TB SSDs, then the entire 7.68 TB capacity of the SSDs is utilized for storage. However, if you add 7.68 TB SSDs to an existing deployment that contains 1.6 TB or 3.2 TB SSDs, then the 7.68 TB SSDs are formatted to 1.6 TB or 3.2 TB for performance. |

Adding the Storage Expansion Shelf
Use the following procedure only if you want to repurpose an existing storage expansion shelf from one Oracle Database Appliance system to another.
Note:
The storage expansion shelf is no longer available for Oracle Database Appliance X7-2-HA and other older models. Use the following procedure only if you want to repurpose an existing storage expansion shelf from one Oracle Database Appliance system to another. If an existing storage shelf is repurposed, that is, moved from a system whereoakd
and Oracle ASM were configured,
then you must clean up the disks on the second JBOD before adding them to the new
deployment. See the topic Performing Secure Erase of Data on Storage
Disks in this guide.
Note:
You can follow the same procedure to add storage to tbe base configuration on Virtualized Platform by usingoakcli
command equivalent of the
odacli
or odaadmcli
commands in the procedure.
Note:
-
Oracle recommends that you add a storage expansion shelf when you have relatively little activity on your databases. When the system discovers the new storage, Oracle ASM automatically rebalances the disk groups. The rebalance operation may degrade database performance until the operation completes.
-
Only offline addition of X7-2 storage expansion shelf to X6-2-HA Oracle Database Appliance is supported.
The addition of the storage expansion shelf includes checks across both nodes. It is important to confirm that SSH does work across the nodes and all users can connect as expected using their shared password.
