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 trac resumes automatically.
You must congure the client network virtual IPs for optimal load balancing. If you do not optimally congure 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 Cluster Conguration Optimal VIPs
ALB Mode Cluster with 2 FS7x00 controllers 8
ALB Mode Cluster with 4 FS7610 controllers 8
LACP Mode Cluster with 4 FS7500 controllers 4
NOTE: You can autoll 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 Conguration, and select the NAS cluster.
2. Click the Network tab.
3. In the Client Network panel, select the network and click Modify.
The Modify Client Network dialog box opens.
4. In the dialog box, you can modify the following elds:
• Name
NOTE: You cannot modify the name of a primary client network.
• Netmask
• Use VLAN tagging
• VLAN ID (1 – 4094)
• Virtual IP addresses
• NAS controller IP addresses
5. Modify the elds 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 Conguration, 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.
