Each Websense X-Series blade server runs Web Security Gateway / Anywhere and can be configured in either of these modes:
Web Security Gateway, optimized for Network Agent (This mode is optional. If used, it applies only to the blade in slot 16.)You choose the mode of a blade server during initial firstboot configuration, as explained in Chapter 3. See Run firstboot for more information about firstboot.
In a fully-loaded chassis (all slots full), more than one instance of Network Agent is likely to be required to handle the traffic load. Deploy Network Agent off-chassis in this situation.
