Abstract

Embodiments of the invention relate to a (e.g., hybrid) redundant array of independent disks (RAID)-based storage control board. Specifically, the present invention relates to a storage control board having a RAID controller with a peripheral component interconnect express (PCI-e) interface. In one embodiment, the RAID controller is coupled to an input/output (I/O) hub and a set (at least one) of PCI-e slots, which themselves can receive cards such as a fiber channel (FC) add-on card, a serial attached small component system interface (SAS) add-on card, or a PCI-e bridge add-on card. The I/O hub can be coupled to a set (at least one) of processors, each of which can be coupled to a main memory module or the like.

Claims
