Rebuilding for Array Codes in Distributed Storage Systems
In distributed storage systems that use coding, the issue of minimizing the communication required to rebuild a storage node after a failure arises. We consider the problem of repa...

MDS Array Codes with Optimal Rebuilding
—MDS array codes are widely used in storage systems to protect data against erasures. We address the rebuilding ratio problem, namely, in the case of erasures, what is the the fr...

Verification of Parity Data in Large Scale Storage Systems
Highly available storage uses replication and other redundant storage to recover from a component failure. If parity data calculated from an erasure correcting code is not updated...

Optimal recovery of single disk failure in RDP code storage systems
Modern storage systems use thousands of inexpensive disks to meet the storage requirement of applications. To enhance the data availability, some form of redundancy is used. For e...
