Страница: 40 / 176

You can only install the Symantec software products for which you have purchased
a license. The enclosed software discs might include other products for which you
have not purchased a license.
Setting up the private network
VCS requires you to set up a private network between the systems that form a
cluster. You can use either NICs or aggregated interfaces to set up private network.
You can use network switches instead of hubs.
Refer to the Veritas Cluster Server Administrator's Guide to review VCS
performance considerations.
Figure 3-2 shows two private networks for use with VCS.

Private network switches or hubs
Symantec recommends configuring two independent networks between the cluster
nodes with a network switch for each network. You can also connect the two
switches at layer 2 for advanced failure protection. Such connections for LLT at
layer 2 are called cross-links.
Figure 3-3 shows a private network configuration with crossed links between the
network switches.
