Cloud storage systems are now mature enough to handle a massive volume of
heterogeneous and rapidly changing data, which is known as Big Data. However, failures …

随着海量存储系统的发展和在复杂环境中的应用, 存储系统的可靠性受到了严重的挑战.
纠删码作为存储系统容错的主要方法越来越受到重视. 首先介绍了当前典型和常见的纠删码技术 …

Large scale storage systems require multi-disk fault tolerant erasure codes. Replication and
RAID extensions that protect against two-and three-disk failures offer a stark tradeoff …

How to improve the performance of single failure recovery has been an active research topic
because of its prevalence in large-scale storage systems. We argue that when erasure …

RAID-6 is widely used to tolerate concurrent failures of any two disks to provide a higher
level of reliability with the support of erasure codes. Among many implementations, one …

With higher reliability requirements in clusters and data centers, RAID-6 has gained
popularity due to its capability to tolerate concurrent failures of any two disks, which has …

Modern storage systems adopt erasure coding to maintain fault tolerance with low storage
redundancy. However, how to improve the performance of degraded reads in erasure-coded …

With the rapid expansion of data storages and the increasing risk of data failures, triple Disk
Failure Tolerant arrays (3DFTs) become popular and widely used. They achieve high fault …

In this paper, we firstly present a new construction of binary maximum distance separable
(MDS) array codes, from which some types of new MDS array codes of minimum distance 4 …

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 …
