Abstract:
A system for a host-based RAID solution in a shared storage environment is provided in which the compute blades of a system are coupled to one or multiple concentrators. The concentrators serve as a switch or expander to couple each of the compute blades to a shared storage resource. Within the shared storage resource, a set of drives is configured in a RAID array. The shared disk drives are partitioned so that each partition is dedicated to one of the compute blades of the system. Multiple sets of drives may be used so that the collective set of drives can be configured as part of a RAID volume that includes mirroring between at least two of the drives of the RAID volume, such as RAID 1 or RAID 0+1, in which each set of drives is a mirror of the other set of drives and the content associated with each of the compute blades is striped across multiple drives in each of the two sets of drives.
