Understanding Discovery Service If you choose to perform an auto discovery, the discovery service will ping and publish a product list to each machine in each subnet listed in the Discovery Configuration Subnet tab and retrieve the product information from the remote machine. To do this, start Discovery and click the Configure button on the Summary tab. The Configuration dialog opens as shown in the following example: The Discovery server initiates an IP address sweep for remote subnets by using the auto-discovered subnets, subnet masks, machine, or Windows domains along with the manually-configured subnets, subnet masks, machines or Windows domains. Selecting this option may increase network traffic and can take a considerable amount of time to complete, depending on the size of your network. We recommend that you run this option during a time of minimum network traffic. Note: If you elect to discover BrightStor products in remote subnets, the discovery service does not rely on a UDP broadcast to locate remote instances. You need to know the size of the subnet and range of IP addresses using a subnet mask. 9-28 Administrator Guide
