RAID controller with eight external SAS ports

The Intel RS3SC008 is a 12Gb/s SAS RAID controller built on the LSI3108 ROC. It delivers scalable performance with support for RAID 0, 1, 5, 10, 50, and 60 across eight external ports, connecting via an x8 PCIe 3.0 interface in a low-profile plug-in card form factor.

Low-profile card draws power from the PCIe slot

The MD2 low-profile form factor fits restricted server chassis without requiring additional power cables beyond the PCI Express 3.0 x8 slot. Thermal output and acoustic profile remain consistent with standard add-in controller operation under typical array workloads.

Upgrades arrays limited to internal ports

This card replaces controllers that lack external connectivity or operate at 6Gb/s, enabling direct attachment of external JBOD enclosures. The jump is worth it when expanding storage beyond the chassis or migrating to 12Gb/s SAS and SATA drives without changing the host server.

Questions about this item

How do I install the RS3SC008 in a PCIe 3.0 x8 slot and which step is often missed?

Insert the low-profile MD2 card into a PCIe 3.0 x8 slot, secure the bracket, then connect the eight external SAS cables; the step most often missed is attaching the auxiliary power cable if the slot cannot supply enough current.

What maintenance or replacement will the RS3SC008 need over time?

The on-board battery that backs the RAID cache must be replaced every few years; without it the controller cannot protect cached writes during a power loss.

What limit appears first when the RS3SC008 runs sustained workloads?

The eight external 12 Gb/s SAS ports share the x8 PCIe 3.0 host link, so aggregate throughput saturates the bus before the individual drive links reach their maximum.
