The control network is required for the operation of the Netra Proxy Cache product's array software.
Obtain your Ethernet hub and an RJ-45 cable for each machine, as described in "Hardware Required".
On each machine in the array, connect the hme1 interface to the hub.
See Figure 2-1, above, for an illustration of the location of the hme1 interface.
If you have only one machine with array software--in effect, a one-host array--and you configure the array software (as described later in this chapter) you must connect the hme1 interface to a hub, just as you would if you had multiple machines in the array. If you have a two-machine array, you can use a back-to-back RJ-45 cable, instead of a hub.
