Managing Static Routes
To minimize hops between routers, static routes are recommended in routed networks when the FluidFS cluster has multiple
direct paths to various routers. Static routes allow you to configure the exact paths through which the system communicates
with various clients on a routed network.
Consider the network shown in the following figure. The system can have only one default gateway. Assume that router X is
designated as the default gateway. Packets that are sent to clients in subnet Y are routed to router X, and are then sent back
(through the switch) to router Y. These packets travel through router X needlessly, reducing the throughput to all subnets in
the network.
Figure 40. Routed Network
The solution is to define, in addition to a default gateway, a specific gateway for certain subnets by configuring static routes. To
configure these routes, you must describe each subnet in your network and identify the most suitable gateway to access that
subnet.
Static routes do not have to be designated for the entire network—a default gateway is most suitable when performance is not
an issue. You can select when and where to use static routes to best meet performance needs.

Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the File System tab.
3. In the File System view, select Cluster Connectivity.
4. Click the Client Network tab. The Static Route panel displays the static routes.
Add a Static Route
When adding a static route, you must specify the subnet properties and the gateway through which to access this subnet.
Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the File System tab.
3. In the File System view, select Cluster Connectivity.
4. Click the Client Network tab.
5. In the Static Route panel, click Create Static Route. The Create Static Route dialog box opens.
6. In the Target Network IP Address field, type a network IP address (for example, 192.0.2.27).
7. In the Netmask or Prefix Length field, type a netmask (for example, 255.255.255.0).
