Figure 71 Basic three host configuration
Two Hosts: Cell Manager/Resolve Agent and application
This solution uses two hosts: one for the Cell Manager and Resolve Agent and one
for the application. Although this configuration does require two machines, the
resource load is split; this can help you avoid performance impact on the application.
Also, the machine that hosts the Cell Manager and the Resolve Agent can be of
minimal processing capacity.
Note that in this configuration, both hosts must be running HP-UX 11.11.
Basic configuration: single host
This solution uses a single host on which the Cell Manager, application, and Resolve
Agent are all installed. As all three components are running on the same physical
machine, they are sharing resources (I/O channels, CPUs, memory, etc.) for their
activities. This configuration minimizes the equipment required to facilitate direct
backup. However, because resources are shared, the Cell Manager and General
