Dual-Crosshatch Disk Array: A Highly Reliable Hybrid-RAID Architecture

چکیده
{In this paper, we propose a highly reliable RAID architecture called a Dual-Crosshatch Disk Array. It uses the proposed interleaved 2d-parity scheme, a low overhead triple-erasure correcting parity organization. It is a hybrid approach of RAID-4 and RAID-5 with one dedicated parity group and another parity group using block interleaved data and parity. The results obtained from simulations indicate that this architecture possesses extremely high reliability with low overheads, good degraded performance, and acceptable normal-mode performance.

Dual Crosshatch Disk Array: a Highly Reliable Disk Array System 1
In this paper, we propose a highly reliable disk array architecture called Dual-Crosshatch Disk Array (DCDA). We have proposed a low overhead, triple-erasure correcting parity organization called interleaved 2d-parity scheme. This parity scheme is used as the basis for the design of the DCDA architecture. DCDA uses a hybrid approach of RAID-4 and RAID-5 with one dedicated parity group and anoth...
متن کاملStripped mirroring RAID architecture
Redundant arrays of independent disks (RAID) provide an ecient stable storage system for parallel access and fault tolerance. The most common fault tolerant RAID architecture is RAID-1 or RAID-5. The disadvantage of RAID-1 lies in excessive redundancy, while the write performance of RAID-5 is only 1/4 of that of RAID-0. In this paper, we propose a high performance and highly reliable disk arra...
متن کاملImplementation of a Secure Data Mirroring pattern for High Reliable Distributed Systems
Disk arrays, or RAIDs, have become the solution to increase the capacity, bandwidth and reliability of most storage systems. In spite of its high redundancy level, disk mirroring is a popular RAID paradigm, because replicating data also doubles the bandwidth available for processing read requests, improves the reliability and achieves fault tolerance. In this paper, we present a new RAID archit...
متن کاملReliable Cluster Computing with a New Checkpointing RAID-x Architecture
In a serverless cluster of PCs or workstations, the cluster must allow remote file accesses or parallel I/O directly performed over disks distributed to all client nodes. We introduce a new distributed disk array, called the RAID-x, for use in serverless clusters. The RAID-x architecture is based on an orthogonal striping and mirroring (OSM) scheme, which exploits full-bandwidth and protects th...
