Graviton 9261-8i SATA/SAS RAID Controller Card 512MB Cache PCI-E 2.0 X8

Eight-port 6Gb/s SATA and SAS RAID controller

This card adds eight internal SATA and SAS ports through two SFF-8087 connectors using a PCIe 2.0 x8 slot. It provides hardware RAID 0, 1, 5, 6, 10, 50 and 60 with 512MB of 800MHz DDRII cache and an optional battery backup module. The LSI 2108 ROC handles 6Gb/s links for demanding storage workloads.

Suits servers needing hardware RAID on internal

Builders who require external ports or a newer PCIe generation should look elsewhere. Systems limited to PCIe 1.0 slots cannot use the full bandwidth of this x8 interface. Workloads that need more than eight internal ports will need additional controllers.

512MB DDRII cache with optional battery backup

The onboard 800MHz cache stores write data during RAID operations and the optional battery module protects that data if power is lost. Without the battery, cached writes are vulnerable during an outage. The cache size is fixed and cannot be expanded on this card.
