Glossary 117
switch fabric card
(SFC)
A board that provides the central switching function for the Data Services
Platform.
target The recipient of initiator commands, usually a volume.
thin-scripting client A client that runs the system’s command-line interface on any qualified host in
the network. The client communicates with the system’s Storage Service
Processor through a secure out-of-band interface, HTTPS. The client must be
installed on a host that has network access to the system. The available clients
are for the Solaris, Microsoft Windows 2000 and Windows 2003, Linux, HP-UX,
and IBM AIX operating environments.
tray See storage tray .
USB flash card or
disk The resident card on which configuration information is stored. Both the
Storage Service processor and the Data Services Platform store their
configurations on flash devices.
virtual disk A collection of disks or extents that acts as one disk. The device that mounts
the virtual disk handles the virtual disk as one disk.
virtualization A design strategy in which storage services are combined with data services to
create useful storage abstractions such as volumes and pools and to handle the
complexity of storage administration. The Sun StorEdge 6920 system uses
virtualization to create and manage storage pools.
volume
A fixed amount of storage, not limited by the physical device. A disk can have
more than one volume, and a volume can span more than one disk.
Applications that use volumes do not need to be aware of physical storage
locations, because the management software maps the virtual address to the
physical address.
WWN Worldwide name. A unique 64-bit number assigned by a recognized naming
authority such as the IEEE that identifies a connection (device) or a set of
connections to the network. The WWN is constructed from the number that
identifies the naming authority, the number that identifies the manufacturer,
and a unique number for the specific connection.
