not had any experience of that but theres no substitution for a fiber based hardware SAN from one of the big names, you are paying for years of R&D and specialisation, i'm sure its cheaper, but IMO its more of a NAS than an enterprise SAN.im going to use datacore for data virtualization its decent stuff
Yeah XSan is the software as far as I can see, only stuff that isn't Apple kit is the fibre switch.The Apple "SAN" is relativley cheap.. as it's just Xserve RAID and Xsan... Heh.
