In face of high partial and complete disk failure rates and untimely system crashes, the
executions of low-priority background tasks become increasingly frequent in large-scale …

Due to the contention for the shared disk bandwidth, the user I/O intensity can significantly
impact the performance of the online low-priority background tasks, thus reducing the …

In this paper, we present a novel coding scheme that can tolerate up to two-disk failures,
satisfying the RAID-6 property. Our coding scheme, Code-M, is a non-MDS (Maximum …

The present disclosure provides a system that includes an array of disk drives and a
controller communicatively coupled to the array of disk drives. The controller is to identify …

Dealing with disk failures has become an increasingly common task for system
administrators in the face of high disk failure rates in large-scale data centers consisting of …

Parity based RAID suffers from poor small write performance due to heavy parity update
overhead. The recently proposed method EPLOG constructs a new stripe with updated data …

RAID-6 is widely applied to tolerate double concurrent disk failures in both disk arrays and
storage clusters. Among numerous erasure codes developed to implement RAID-6 …

In the era of big data, the traditional RAID storage system has been incapable of meeting the
requirements of performance and reliability for the large amount of data storage and …

Provided are a computer program product, system, and method for using an alias volume
name for a volume to allocate space to a data set. An assignment of a plurality of volumes to …

BACKGROUND Currently in RAID configurations hard disk bad block management is
provided through its special reserved area of the hard disk called GLIST. In a hard drive, if a …
