Just say no to SANs #

This isn't true. iSCSI will provide all the same functionality that you'd get from a SAN, at least as far as a VMware ESX cluster would care. Arguably faster than a SAN, too (depending how much you like trunking). And definitely plenty big time cheaper than a SAN.
The last is probably the most important -- setting up a separate GbE network using commodity switches, commodity NICs, commodity SAS/SATA drives in a commodity box running commodity software (GNU/Linux) to create your own phatdisk is becoming particularly compelling.
iSCSI gets me to about A$2K / TB - but the great thing is the non-linear premium of adding new servers (compare and contrast most port-based FC switch costing plans and exxy HBA's).
