Understanding SANs
At work a SAN (Here is a basic guide to SANs from Brocade) has just been installed for testing. I am coming tounderstand that Fibre channel is just another way to make networking expensive before ethernet catches up (as are Infinband adapters ref. Virgina Techs BigMac Cluster). But I don't understand why people want to use iSCSI (SCSI over IP). Either you are moving the maintaince cost of disks in machines (which you can fix anyway using NAS) and if you want to share the data then you also need cluster filinf systems. For databases where speed is important I can see the point, but surely not for most things.
