1. On the source cluster, select NAS, expand Local Volumes, and select the NAS volume that you are replicating. 2. Click Replicate. 3. Click Yes. 4. (Optional) Display the Alarms and Operations toolbar and click the Failback Operations tab. NAS Replication Network Architecture NAS replication depends on specific network capabilities, such as TCP ports opened over a secure tunnel and communication using the storage area network (SAN). NAS replication opens several TCP ports. The ports are opened over a secure tunnel between the source NAS cluster and the destination NAS cluster. The ports are opened during each replication cycle. Communication between clusters occurs over several ports as well as in both directions over the SAN. Data flow for NAS replication occurs over the SAN network exclusively. Data flows between Ethernet ports on each NAS controller. See Figure 27. NAS Replication Data Flow for a high-level diagram of NAS replication data flow. Figure 27. NAS Replication Data Flow Network Setup and Component Requirements Specific network configuration requirements must be met for replication to function. NAS replication network requirements include: • A path through the firewall for the SAN's physical and logical ports/IP addresses used on the: - Dell EqualLogic arrays - NAS controllers • A path through the firewall for the appropriate TCP/UDP ports • Static routes (required only when using a wide area network [WAN]) NOTE: As of v3.0, jumbo frames are not required for WANs or the SAN network. The following physical NIC (Network Interface Controller) ports and IP addresses must be accessible through the firewall. SAN ports: 280 About Data Recovery
