RAID controller with eight 6Gb/s ports
The OIAGLH 9261-8i is a MegaRAID controller card designed for servers and workstations that need hardware RAID across multiple drives. It connects through a PCI Express 2.0 x8 slot and manages up to eight SAS or SATA devices at 6Gb/s per port. The card targets administrators building storage arrays for virtualization, databases or high-performance computing workloads.
Green PCB with internal mini-SAS connectors
The board uses a green PCB and provides eight internal ports via mini-SAS connectors, allowing direct cabling to drive backplanes or individual drives inside the chassis. A 512MB DDR2 onboard cache buffers read and write operations to improve array efficiency. The PCIe 2.0 x8 interface supplies enough bandwidth for the supported RAID levels without requiring a newer slot generation.
Upgrades software RAID or older 3Gb/s controllers
This card replaces host-based software RAID or earlier 3Gb/s hardware controllers when data protection and sustained throughput become critical. The jump is worth it for workloads that need RAID 5, 6, 10, 50 or 60 with dedicated cache and battery-backed write protection. It is not for systems that lack a PCIe 2.0 x8 slot or for builders who need external port connectivity.

Questions about this item
What bandwidth does the PCIe 2.0 x8 interface cap at for the 9261-8i?
The PCIe 2.0 x8 slot limits the card to the 2.0 generation's per-lane rate, which in practice caps total throughput below the eight 6Gb/s ports' combined ceiling.
What physical slot and clearance does the 9261-8i require?
It needs a full-height PCIe 2.0 x8 slot (or wider) and enough surrounding space for the eight internal mini-SAS connectors and the green PCB's heatsink.
How is the 9261-8i installed, and which step is often missed?
Seat the card in the x8 slot, attach the mini-SAS cables to the eight ports, then enter the BIOS utility to initialise the 512MB DDR2 cache and create the RAID volume before the OS loads.
