SAN and faster IO

Are there ways to tweak a SAN for faster IO. For some reasons our SAN is not
giving us a great IO throughput compared to the servers that have a Direct
Attached Storage. Similar configuration as far as RAID and drive letters are
concerened and also layout of the databases. Doing some comparisons relates
to disk bottlenecks.. Has anyone tweaked any HBA or any setting that we
might see some better performance or still better if there are any SAN
related publicly accessed articles .Using SQL 2000Have you talked to the SAN vendors? Typically they configure it for optimum
throughput depending on the type of usage you expect...
