HBA Features

Language:

The Oracle Storage 12 Gb SAS PCIe RAID HBA, Internal: 16 Port and 2 GB Memory (part number: 7116970) is a low-profile, PCI Express 3.0 RAID controller that supports 16 internal 12 Gb/s SAS connectors through four internal mini-SAS HD ports. The 16 connectors on the board enable direct connection to all internal drives, and eliminate the need for a SAS expander. Data that is cached on the HBA is protected, in the event of a power failure.

The HBA supports the following features.
