Is SnapDrive and SnapManager for Exchange really needed to run Exchange with databases on a filer using iSCSI? Seems to me that it would be possible to use MS's iSCSI initiator then manually create the iSCSI Groups and LUNs where the databases and logs will be stored then use scripts to perform routine maintenance and backups. Anyone out there using Exchange and iSCSI without SnapDrive and SnapManager for Exchange?
