Single disk failure recovery for X-code-based parallel storage systems
In modern parallel storage systems (eg, cloud storage and data centers), it is important to
provide data availability guarantees against disk (or storage node) failures via redundancy …

Accelerate rdp raid-6 scaling by reducing disk i/os and xor operations
Disk additions to an RAID-6 storage system can increase the I/O parallelism and expand the
storage capacity simultaneously. To regain load balance among all disks including old and …

Rethinking RAID-5 data layout for better scalability
In RAID-5, data and parity blocks are distributed across all disks in a round-robin fashion.
Previous approaches to RAID-5 scaling preserve such round-robin distribution, therefore …
