Using the Centillion EtherSpeedII Switch Modules

Giving a Server a Dedicated Port

Moving a server from a 10 Mb/s shared-media connection to a dedicated port on the EtherSpeedII 10/100BASE-T switch module or the EtherSpeedII 100BASE-FX switch module improves server response time and increases throughput capacity. For even higher performance, upgrade the server to 100 Mb/ s and the switch modules can autonegotiate for 100 Mb/s.

In Figure 2-2, the “Before” example shows clients and servers sharing the same network segment. The “After” example shows the same clients assigned to different segments through a shared hub (either 10/100 Mb/s or directly connected) and the original servers connected to switch ports on a Centillion 50 chassis. In addition, two servers have been added through 10/100 Mb/s connections.
