Answer
# 1
A group of disks may be interleaved to speed up data
transfers in a manner analogous to the speedup achieved by
main memory interleaving. Conventional disks may be used
for interleaving by spreading data across disks and by
treating multiple disks as if they were a single one.
Furthermore, the rotation of the interleaved disks may be
synchronized to simplify control and also to optimize
performance. In addition, check- sums may be placed on
separate check-sum disks in order to improve reliability.
In this paper, we study synchronized disk interleaving as a
high-performance mass storage system architecture. The
advantages and limitations of the proposed disk
interleaving scheme are analyzed using the M/G/1 queueing
model and compared to the conventional disk access
mechanism.
