RAID Controller with 512MB Cache

The Graviton LSI 9261-8i is a PCI-E 2.0 x8 RAID controller card that delivers eight internal 6Gb/s SATA and SAS ports through two SFF-8087 Mini-SAS connectors. It uses the D2616-A12 SAS 2108 RAID-on-Chip with 512MB of 800MHz DDRII cache to accelerate array operations. The card supports RAID levels 0, 1, 5, 6 and spans 10, 50, 60 for flexible data protection.

Suits Internal Array Builds

This card suits builders who need hardware RAID for up to eight internal SATA or SAS drives in servers or workstations handling video editing, surveillance, medical imaging or database workloads. It is not for systems that lack a PCI-E 2.0 x8 slot or installations requiring more than two internal Mini-SAS connections. Buyers needing external drive enclosures should look elsewhere.

Deciding Specification: Eight 6Gb/s Ports

The single specification that decides fit is the eight internal 6Gb/s ports presented via two SFF-8087 connectors. If the target chassis and backplane provide exactly eight drive bays with Mini-SAS cabling, this controller matches directly. If the build requires a different port count, connector type or external connectivity, this is not the correct part.

Questions about this item

Does the LSI 9261-8i need a PCI-E 2.0 x8 slot and what bracket is included?

It fits a PCI Express 2.0 x8 slot and ships with a standard bracket for full-height cases.

How do I connect drives to the two SFF-8087 ports and which RAID levels are supported?

Use Mini-SAS SFF-8087 cables to the backplane; the D2616-A12 ROC handles RAID 0, 1, 5, 6, 10, 50 and 60.

When should I replace the 512 MB DDRII cache or add the optional backup module?

Replace the cache if the controller reports memory errors; add the backup module to protect cached writes during power loss.
