3 Faults Tolerant Orthogonal RAID for Large Storage

Recently, the demand of low cost large scale storage increases. We developed VLSD (Virtual Large Scale Disks) toolkit for constructing virtual disk based distributed storages, which aggregate free spaces of individual disks. However, in order to construct large-scale storage, more than or equal to 3 fault tolerant RAID is important. In this paper, we propose MeshRAID that is 3 fault tolerant orthogonal RAID. And, we implement MeshRAID using VLSD. It is easy to implement MeshRAID using various classes in VLSD. From the viewpoint of its features, MeshRAID is addressed between RAID55 and NaryRAID.
