BACKGROUND Issues of data storage arise almost everywhere in the mod ern world,
especially as the need for ever more storage increases. Some of the typical goals for a data …

It is indispensable to scale erasure-coded storage clusters to meet requirements of
increased storage capacity and I/O performance. In this study, we propose an efficient …

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 …

(57) ABSTRACT A data storage system includes a plurality of hosts, each of which includes
at least one processor and communicates over a network with a plurality of storage nodes, at …

Current algorithms used to upgrade RAID arrays typically require large amounts of data to
be migrated, even those that move only the minimum amount of data required to keep a …

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 …

Data deduplication is an important component of enterprise storage environments. The
throughput and capacity limitations of single node solutions have led to the development of …

This paper discusses using hard drives that integrate a key-value interface and network
access in the actual drive hardware (Kinetic storage platform) to supply file system …

The ever-growing amount of data requires highly scalable storage solutions. The most
flexible approach is to use storage pools that can be expanded and scaled down by adding …

Disk additions to a RAID-6 storage system can simultaneously increase the I/O parallelism
and expand the storage capacity. To regain a balanced load among both old and new disks …
