For those rare cases when you need your SATA/SCSI cable (which is essentially what a SAN is) routed to another physical location there is software available to tunnel ethernet to wherever you need it routed. I find this to be far more attractive than making everyone have to deal with a protocol bloated by those afraid of not being able to route. It is in harmony with the UNIX/Internet philosophy of using small tools/separate layers to do different jobs. I also like the security implications of non-routable disk traffic. Fibrechannel isn't routable and for some reason nobody brings up these issues when fibrechannel is recommended. -- Tracy Reed http://tracyreed.org
