Adding a Second Server
Adding a Second Server
The load on the SNAplus2 server increases as more clients are added to
the network in the local branch of the bank. The bank invests in a second
SNAplus2 server that runs in parallel to the first, as shown in Figure
3-3, “LAN with Two SNAplus2 Servers.” Adding a second server enables
local load-balancing across the two servers; the second server also
provides a hot-backup capability.
Figure 3-3 LAN with Two SNAplus2 Servers
As the local network expands, the two servers enable the network to
support increased traffic without duplicating all the resources in the
network. Also, the number of additional links required to the host is
reduced, because all of the clients share the links between the server and
the host.
