Introduction

System Hardware Features

The Global Site Selector 4490 is deployed at strategic locations within your network. The GSS performs two major functions when deployed with other SLBs:

It takes an active role in the domain name server (DNS) infrastructure, connecting clients to SLBs that support the requested website.

It continuously monitors the load and availability of SLBs in its network, selecting the SLB that is most able to answer each client request.

By off-loading DNS resolution from traditional DNS servers, the GSS optimizes global site selection and increases DNS responsiveness. And through its monitoring of load and availability the GSS increases the fault tolerance and scalability of large websites and data centers.

System Hardware Features

The Cisco Global Site Selector 4490 is configured for AC-input power and has a single AC-input power supply. The GSS 4490 comes with an integrated dual-port Ethernet controller. This controller provides an interface for connecting to 10-Mbps, 100-Mbps, or 1000-Mbps networks.

The GSS 4490 has two 10BASE-T/100BASE-TX/1000BASE-TX Ethernet ports with RJ-45 receptacles. Both Ethernet ports support autonegotitate, full-duplex, or half-duplex operation on an Ethernet LAN.
