Storage Systems
PCI has become a common backplane technology for mainstream storage systems. Although it provides a good mix of features, low cost, and throughput, the “bus” has become a performance bottleneck. Figure B-5 on page 995 shows the use of PCI Express in a storage system. Systems similar to the one shown in Figure B-5 on page 995 can be built on a motherboard, or as part of a backplane. The discussion in this section applies to both form factors.
