Glossary
120 Storage Management Appliance Software V2.0 User Guide
controller pair
Two interconnected controller modules that control a single disk array to improve performance and
maximize availability.
device (SAN)
A host computer or a storage element connected to a Storage Area Network (SAN). A device is
usually connected to a user port on a Fibre Channel Switch (FCS) or hub. The Storage
Management Appliance discovers devices on the local SAN. See Chapter 4, “ Discovering Devices
and Applications ,” on page 41 for information about devices and discoveries.
discovery
Process used by the Storage Management Appliance to identify devices and applications
associated with a SAN. To locate all such components you must use both IP and SAN discoveries.
See Chapter 4, “ Discovering Devices and Applications ,” on page 41 for information about
discoveries.
element manager
A software application used to manage several storage elements of the same type. The HSG and
HSV Element Managers are installed with the Storage Management Appliance Software are
examples of element managers. Use the HSG Element Manager to manage several HSG disk
arrays (storage elements). Access the HSG and HSV Element Managers on the Devices page
( Figure 32 ).
event
A condition change on any network device or host computer that generates a log entry or message.
For example, a device going offline is an event. Information about an event is useful for managing
a network and especially troubleshooting. An SNMP agent usually has the ability to report a
number of defined events by generating a SNMP trap message. See Chapter 5, “ Monitoring
Events ,” on page 57 for more information about events and logs.
fabric
That part of a Storage Area Network (SAN) consisting of switches, hubs and links that allow hosts
to exchange data with storage elements. With multiple switches, the fabric includes the
Inter-Switch Links (ISLs) used to interconnect switches. The Storage Management Appliance uses
discoveries to identify both hosts and fabric components of a SAN.
Inter-Switch Link (ISL)
A fibre cable connecting a port on one Fibre Channel switch to a port on another switch.
IP discovery
A discovery type that identifies LAN connected SAN devices with an enabled SNMP agent. The
IP discovery process queries every IP address in one or more specified IP ranges using one or more
community strings. See “ About Discoveries ,” on page 42 for more information.
