SUMMARY:BASIC regenerating codes for distributed storage systems
DESCRIPTION:Reliability in disk arrays is provisioned by storing the data
 with redundancy. For example\, in RAID-6\, we protect the data from being
 lost by introducing parity-check disks\, so that any failure of two disks
 can be restored. In a large-scale distributed storage system\, disk
 failures and repairs are common day-to-day event\, and incur excessive
 amount of traffic for the recovery of failed disks. A class of codes\,
 called regenerating codes\, was introduced by Dimakis et al. for the
 purpose of reducing the required repair traffic. Like Reed-Solomon codes\,
 most of the existing regenerating codes rely on the arithmetic of finite
 fields. The computational complexity of encoding and decoding may render
 the system impracticable if the size of the finite field is large. In this
 talk\, we discuss a construction of regenerating codes called Binary
 Addition and Shift Implementable Convolutional (BASIC) codes\, in which
 finite field additions and multiplications are replaced by bit-wise
 exclusive OR and bit-wise shifting. The advantage of regenerating code is
 thereby attained with lower computational cost. This is a joint work with
 Minghua Chen\, Hanxu Hou and Hui Li.
