Discovering Devices and Applications

About Devices
The Storage Management Appliance is capable of identifying particular devices
and applications in your storage area network using one or more discovery
processes. Devices include host computers, Fibre Channel switches, Modular
Data Routers (MDRs) and NAS devices. A storage element is defined as any
storage system with a single controller (or pair of controllers) connected to a
switch port. Storage elements can include a wide range of technologies that
include disk arrays and tape devices.
Many devices can be identified by querying an SNMP agent operating on the
device. Some devices have no SNMP agent and must be identified by querying the
associated management application.
About Discoveries
The Storage Management Appliance uses a discovery process to identify devices
and applications operating in your storage network environment. You can create
any number of discovery processes and each process can have a different set of
parameters. Each process is referred to as a discovery.
You can schedule a discovery to run at regular intervals or to run only on demand
which means you must start the process manually with a Management Appliance
discovery start feature.
To find all devices in your Storage Area Network (SAN ) you must use two
discovery types—IP discoveries and SAN discoveries.
IP Discoveries
The Management Appliance is connected to your organization’s LAN via a
Network Interface Card and an Ethernet cable. You can define any number of IP
discoveries that query SNMP agents at specified IP addresses. An IP discovery
can identify any device connected to the LAN with an enabled SNMP agent. Such
devices include host computers and Fibre Channel switches.
IP discoveries also identify any Management Appliances connected to your
storage network.
