90 Glossary
FC (Fibre Channel)
A high speed data transfer architecture. Using optical fibre to connect devices, Fibre Channel
communications are serial communications that occur at full duplex and achieve data transfer rates of 200
MBps.
FCB (Fibre Channel blade)
A board-level component of the Scalar 12000 or the Pathlight VX that is responsible for the data interface
between hosts and storage devices.
Graphical panel
The upper right quadrant of the AMC window, where configuration information is displayed in graphical
format.
GUI (Graphical User Interface)
A computer environment that provides a visual view of a system by incorporating windows, icons, menus,
and a pointing device. Sometimes referred to as UI (user interface).
Health check
An AMC feature that provides predictive alerts, warning of any loss of connectivity or device failure using
local or remote alerts. Health check allows administrators to correct faults before they affect backup or other
data transfer operations.
Host initiator
A host bus adapter that provides the host with a Fibre Channel port capable of initiating SCSI commands
at the host’s request.
HRS (Host Registration Service)
Software that presents host information the AMC server uses to manage host access and data retrieval.
This information includes host name, host type, host connection and the online or offline status.
HTTP (Hypertext Transfer Protocol)
The communication rules by which a Web browser (client) and a server delivering Web pages exchange
information.
HTTPS (Hypertex Transfer Protocol over Secure Socket Layer)
URI scheme indicating a secure HTTP connection.
I/O blade
A board-level component of the Scalar 12000 or the Pathlight VX that is responsible for the data interface
between hosts and storage devices. See FCB.
IP (Internet Protocol)
A protocol that specifies the formats of packets and addresses. Addresses are formulated as dotted quads,
for example, 123.456.789.123.
ISV
Independent software vendor
Library
A large-scale tape device with robotics that can house multiple tape drives and a significant number of tape
cartridges.
LMC (Library Management Console)
LMC is the management software for the Scalar i2000 library that runs on that library’s touch screen. It can
also run remotely if there is a Scalar i2000 in the SAN. It is client software that communicates with the AMC
server.
