Optimal Virtual IP Assignment To optimize availability and performance, client connections are load balanced across the available NAS controllers. NAS controllers in a NAS cluster operate simultaneously. If one NAS controller fails, clients are automatically failed over to the remaining controllers. When failover occurs, some SMB clients reconnect automatically, while in other cases, an SMB application might fail and the user must restart it. NFS clients experience a temporary pause during failover, but client network traffic resumes automatically. You must configure the client network virtual IPs for optimal load balancing. If you do not optimally configure the client network virtual IPs, the system prompts you to assign an optimal number of virtual IP addresses for the client network. Use the guidelines in the following table to set up an optimal number of VIPs. Bonding Mode ALB Mode ALB Mode LACP Mode Cluster Configuration Cluster with 2 FS7x00 controllers Cluster with 4 FS7610 controllers Cluster with 4 FS7500 controllers Optimal VIPs 8 8 4 NOTE: You can autofill the VIPs for the client network and NAS controller IP addresses. Viewing or Modifying a Client Network To view or modify an existing client network in a NAS cluster: 1. Click Group, expand Group Configuration, and select the NAS cluster. 2.

Modify the fields as needed and click OK. The client network details are updated and displayed under Client Network on the Network tab. Deleting a Client Network To delete an existing client network in a NAS cluster: 1. Click Group, expand Group Configuration, and select the NAS cluster. 2. Click the Network tab. 3. Under Client Network, select the network and click Delete. The Delete client network dialog box opens. NOTE: You cannot delete a primary client network. 4. To delete the selected client network, click Yes. The client network is deleted from the NAS cluster and removed from the Client Network panel. NAS Container Operations 199
