Supported Disk Shelf Combinations and HBAs
Disk shelves are supported by specific HBAs in the controller, and can be combined in certain configurations within a system. Use the following table to determine the HBA type required by each disk shelf model.
Table 2-1 Required HBA per Disk Shelf Model
| Disk Shelf Model | Required HBA |
|---|---|
|
Oracle Storage Drive Enclosure DE3-24P All-Flash |
SAS-3 4x4 port HBA |

The following table describes which disk shelf models can be used together for which controller configurations, starting with software release OS8.7.0. DE2-24 disk shelf connection to ZS7-2 controllers is supported in software release OS8.8.4 and later. See Cabinet and Cabling Guidelines in Oracle ZFS Storage Appliance Cabling Guide, Release OS8.8.x for disk shelf intermixing guidelines and all-flash disk shelf usage. To understand which controllers support which HBA types, see Maximum Disk Shelves per Controller Configuration.
Note:
For optimal performance, do not attach all-flash and non-all-flash disk shelves to the same SAS-3 HBA.Table 2-2 Supported Disk Shelf Combinations per Controller Configuration
| Controller Configuration | DE3-24P All-Flash | All DE3 Disk Shelves (except All-Flash) | All DE2 Disk Shelves | DE3 and DE2 Disk Shelves | DE2 and Sun Disk Shelves |
