In order to validate the improved coordination algorithm, this thesis designs and implements a two-level storage system test bed, and USES different prefetching algorithm in it.

But cost can be divided into two high-level categories: the cost of the physical storage ecosystem itself and the cost of managing it.

Each host had at least two FC adapters connected to our SAN. The following diagram shows the high-level view of the SAN storage and AIX LPAR connectivity to the existing SAN fabric.
