All sorts of factors about the SAN, such as block size, stripe size, RAID level(s), number of spindles in extents, extent spanning, multipathing per i/o, and probably a dozen other factors can affect how well a particular SAN or SAN configuration handle small or large files. ...Take it from a guy running a Cyrus install of 12 million tiny files who is very unhappy with how his (current) SAN performs for such an application. (And yes, of course, filesystem issues affect performance as well.)
