A customer has an EMC NetWorker server running on a Microsoft Windows host, one storage node running on a Windows host, and two storage nodes running on Solaris hosts. Data Protection Advisor (DPA) will be installed on a separate Windows host. The customer requires that system performance information be collected from the backup server and all storage nodes. A Collector will be installed on the DPA server by default. At a minimum, how many additional Collectors need to be deployed to gather performance information assuming all permissions are granted?
