3-2 CHAPTER 3: MAKING CONNECTIONS
Aggregating
Servers
You can use the Hub 1000 SX downlinks to aggregate servers into server
farms. First, install 3Com 3C985-SX Gigabit EtherLink
®
Server NICs in
each server. Then, connect up to eight servers through the downlinks.
The hub’s optional gigabit interface connector (GBIC) uplink can connect
to a 3Com SuperStack II Switch 9300 Gigabit Ethernet switch, thereby
connecting to the network backbone. See Figure 3-1.

Connecting a
Power Workgroup
A power workgroup consists of a small number of servers, or a small
number of sophisticated users on high-end workstations. Such a
workgroup requires very high performance to run applications that
move and process massive amounts of data in real time (for example,
medical imaging, video editing, film postproduction, CAD/CAM, or
digital prepress).
You can provide gigabit bandwidth to a power workgroup as shown in
Figure 3-2.
