View DNS Servers and Suffixes
View the current DNS servers providing name resolution services for the FluidFS cluster and the associated DNS suffixes.
Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the File System tab.
3. In the File System view, select Client Accessibility. The DNS panel displays the DNS servers and suffixes.
Add or Remove DNS Servers and Suffixes
Add one or more DNS servers to provide name resolution services for the FluidFS cluster and add associated DNS suffixes. Adding
multiple DNS servers and suffixes ensures continued name resolution services in the event of a DNS server failure. If the FluidFS cluster
cannot establish contact with the preferred server, it will attempt to connect to the remaining servers in order. Remove a DNS server or
DNS suffix if it is no longer available or used.
Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the File System tab.
3. In the File System view, select Client Accessibility.
4. In the DNS panel, click Edit Settings. The Edit DNS Settings dialog box opens.
5. To add a DNS server, type the IP address of a DNS server in the DNS Servers IP Addresses field and then click Add.
6. To remove a DNS server, select it from the DNS Server IP Addresses field and click Remove.
7. To add a DNS suffix, type the DNS suffix in the DNS Suffixes field and then click Add.
8. To remove a DNS suffix, select it from the DNS Suffixes field and click Remove.
9. Click OK.
Change the Order of Preference for DNS Servers and Suffixes
Change the order of preference for a DNS server or DNS suffix. If the FluidFS cluster cannot establish contact with the preferred server,
it will attempt to connect to the remaining servers in order.
Steps
1. In the Storage view, select a FluidFS cluster.
2. Click the File System tab.
3. In the File System view, select Client Accessibility.
4. In the DNS panel, click Edit Settings. The Edit DNS Settings dialog box opens.
5. DNS servers are listed in descending order of preference.
• To increase the order of preference for a DNS server, select a DNS server and click Up.
• To decrease the order of preference for a DNS server, select a DNS server and click Down.
6. DNS suffixes are listed in descending order of preference.
• To increase the order of preference for a DNS suffix, select a DNS suffix and click Up.
• To decrease the order of preference for a DNS suffix, select a DNS suffix and click Down.
7. Click OK.
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.
