## Up to Eight SSDs Can Now Be Installed In Any SPARC T3-1 Server

Solid State Drives (SSDs) that have been qualified by Oracle can now be used in SPARC T3-1 servers configured with eight-disk capable backplanes. Qualified 32-GB SSDs can also be used in servers with sixteen-disk backplanes.

Note - Only SSDs with 32-GB capacity can be used in sixteen-disk backplanes.

To see the list of SSDs that have been qualified for use in SPARC T3-1 servers, go to the following page in the Sun System Handbook:

https://support.oracle.com/handbook_private/Systems/SPARC_T3_1/components.html

Note - The Sun System Handbook is on the Oracle support web site, so you will be asked to log in.

The following is a summary of the rules governing the deployment of SSDs in a SPARC T3-1 server:

- A maximum of eight SSDs can be installed in a server regardless of the type of backplane.

- SSDs and traditional disk-based hard drives can be installed in any numerical combination, so long as the number of SSDs does not exceed eight.

- SSDs and traditional disk-based hard drives can be distributed among the disk slots in any configuration.

- RAID volumes must not be configured with a mix of both SSDs and disk-based hard drives. Either storage technology can be used in a RAID array, but mixing them in a single volume places the integrity of the data at risk.

- In servers with sixteen-disk capable backplanes that use the onboard SAS-2 controllers, the backplane must be partitioned into two eight-disk zones. For disk zoning details, see Disk Zoning Rules for Backplanes With Sixteen-Disk Capacity and Disk Zone Management Using the `zoningcli` Command.

- In servers with sixteen-disk capable backplanes that use an internal PCIe RAID HBA instead of the onboard SAS-2 controllers, disk zoning must be disabled. In this case, all disks in the backplane are seen by the HBA as a pool of storage devices. See Disk Zone Management Using the `zoningcli` Command.
