Packets that are sent to clients in subnet Y would be routed to router X, which would then be sent back (through the switch) to router Y. This means these packets travel through router X needlessly, reducing the throughput to all subnets in your network.

The solution is to define, in addition to a default gateway, a specific gateway for certain subnets–configuring static routes. To do this you would have to describe each subnet in your network and identify the most suitable gateway to access that subnet.

You do not have to do so 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 your performance needs. See "Managing Static Routes" on page 137.

Configuring DNS

Domain Name System (DNS) is the name resolution service that enables users to locate computers on a network or on the Internet (TCP/IP network) by using the domain name. The DNS server maintains a database of domain names (host names) and their corresponding IP addresses providing name-to-address and address-to-name resolution services on the IP network. You can configure one or more external DNS server (external to PowerVault NX3500 but within the site) to be used for name resolutions.

To configure DNS parameters, select System ManagementNetworkDNS Configuration.
