HBA Features

The Sun Storage 6 Gb SAS REM RAID HBA (SGX-SAS6-R-REM-Z, SG-SAS6-R-REM-Z) is a RAID-on-Chip (ROC) PCI Express 2.0 RAID host bus adapter (HBA) based on the LSI SAS2108 ROC. The HBA hard disk drive (HDD) interface provides links for up to eight HDD ports.

The HBA interfaces with the host system though a 210-pin mezzanine plug connector that implements x8 lane PCI Express bus signaling. You can connect SAS hard disk drives or SATA hard disk drives to the HBA with the same mezzanine connector. The interface can provide links for up to eight HDD ports.

You can connect the LSI intelligent Battery Backup Unit 08 (LSIiBBU08) directly or remotely to the HBA. For more information about this battery backup unit, refer to the LSI document, MegaRAID iBBU08 Intelligent Battery Backup Unit Quick Installation Guide, located at the Oracle support area of the LSI web site:

The HBA supports the following features:

• PCI Express host interface, as defined in the PCI Express Specification, revision 2.0, that is backward compatible with previous revisions of the PCI bus and PCI-X bus

• PCI Express x8 lane width (with support for x16 connection)

• Simplified cabling between devices with point-to-point, serial architecture

• PCI Express performance up to 5 Gbit/s per lane

• High performance through the MegaRAID Firmware Interface (MFI) architecture

• High throughput and low CPU utilization to offload the host processor
