110 Glossary
SFM (Scalar Firewall Manager)
A virtual LUN mapping scheme for Fibre Channel hosts, allowing an overall LUN total of 2048 devices to be
virtually remapped on a SAN-wide basis.
SNC (Storage Networking Controller)
ADIC term for a storage networking appliance. The SNC enables high-performance, networked
communications that support intelligence functionality within the Scalar storage system.
SNC menu
An AMC menu that allows the user to configure the appliance parameters for an SNC. It appears when an
SNC is right-clicked from either the navigation panel or the graphical panel.
SNMP (Simple Network Management Protocol)
SNMP is the protocol governing network management and the monitoring of network devices and their
functions.
Status/Message area
The bottom of the AMC window, where event traps and other messages are posted.
Target ID
SCSI bus address. See also LUN.
Trap
An SNMP alert that is sent to the AMC client when predefined conditions are met.
Received event traps
A named window that is always opened when the AMC client is running. In it, events that are configured to
precipitate traps are displayed. Events must have been previously configured to produce traps in order to
display in this window.
Navigation panel
The left half of the AMC window, where SAN components are listed in a highly conventionalized visual/
textual format.
View
In AMC, a named graphical representation of a portal, generally one that has been saved to preserve a
particular categorization.
Virtual device
For Pathlight VX, a device presented to an operating environment by control software or by a volume
manager. From an application standpoint, a virtual device is equivalent to a physical one.
Virtual library
For Pathlight VX, disk storage that appears as if it were a tape drive or tape library.
VLI (Virtual Library Interface)
The management interface for the Pathlight VX.
Virtualization
For Pathlight VX, writing tape media data to disk.
VPM (Virtual Private MAP)
A per-host, virtual LUN mapping scheme for SCSI-attached hosts. It allows each host to see the LUN map
as if the LUN map began at “1,” subject to an overall device total of 2048, and a per-host device total of 256.
VPS (Virtual Private SAN)
A SAN-wide, virtual LUN mapping scheme for FC-attached hosts, allowing an overall LUN total of 2048
devices.
WWN
World Wide Name, a unique number assigned by a recognized naming authority. The WWN is integral to
Fibre Channel operations.
