It sounds very promising though, certainly better than working with the proprietary API of whoever your SAN-vendor is to create a new LUN for every VM. Also, the machine we have got here, a Dell PowerVault, appears to be limited to at most 255 LUNs. I don't if that's a limitation of iSCSI or just a problem of this particular array.
