Executive Summary
The transition to 4Gb Fibre Channel SANs is happening now. Newer technologies like server virtualization, multi-core processors, and faster server host bus architectures are driving increased IOPs and bandwidth requirements on the server side. The move to 4Gb FC on switches and storage arrays and the evolution of denser architectures on servers and storage is also demanding need for higher scalability in the SAN infrastructure. To meet these ever-growing demands on the SAN, it is imperative that enterprise SAN users deploy a scalable HBA architecture that can
address a full spectrum of concerns including cost, performance, backward compatibility, and most importantly future scalability.
