Chargeback feature allows schools to recoup cost for storage use
Min of 500 gigs set aside for DRC usage Static mappings with ACL to allow for secure
communication between SANs

Two annual enrollment periods into the DRC– Allow for data migration and
placement within the DRC
Data integrity tested twice a year between sites
Replication is encrypted between sites

bandwidth and data push User adoption – beyond
technology departments Different SAN versions? Remote site down times? Bandwidth throttling and
expectations Replication software not
