Dell SC4020 Deployment Manual page 13

When replication is licensed, the SC4020 can use the front-end iSCSI ports to replicate data to
another Storage Center.
• SAS: Hosts or servers access storage by connecting directly to the storage system SAS ports.
NOTE: When replication is licensed on an SC4020 the SC4020 can use the embedded MGMT and
REPL ports to perform iSCSI replication to another Storage Center. In addition, the SC4020 can use
the embedded MGMT and REPL ports as front-end iSCSI ports for connectivity to host servers.
