All primary server virtual machines (VM) are stored on a two(primary and secondary) node storage area network (SAN). Each VM stores it's live data on the primary SAN node (zfs1.sebeka.k12.mn.us). The primary SAN node currently is storing 15 daily snapshots. Every night daily changes are sent to the secondary SAN node(zfs2.sebeka.k12.mn.us).
