Principles Of Operation Of Gxcc - Fujitsu Siemens Computers pmn User Manual

Technical design
GXCC (Global Extended Control Center) is a program with an X user interface that provides
a complete graphical representation of a CentricStor system, and covers all connected
devices and ISPs (Integrated Service Processors) such as ICPs (Integrated Channel
Processors), IDPs (Integrated Device Processors), and VLPs (Virtual Library Processors).
GXCC processes all ISPs and other components of a CentricStor cluster as if they were a
single unit.
Displays and operations within an ISP are implemented in the downstream XTCC appli-
cation (Extended Tape Control Center). An XTCC application is started by choosing the
"Show Details" command from the function menu of an ISP.
GTCC and XTCC are standard components of the CentricStor software package, and are
installed on all the CentricStor ISPs. They can also be operated on a computer
(workstation) that is running independently of CentricStor. To permit this, a GUI CD is
supplied with each CentricStor which can be used to install the GUI software for monitoring
a CentricStor system under the operating systems MS-Windows 95/98/NT/2000/XP,
LINUX, SOLARIS and SINIX-Z.

5.1.2 Principles of operation of GXCC

As shown in the figure below, the CentricStor user interface is represented by the interaction
of three components:
– InfoBrokers exchange information with the individual CentricStor processes. An
InfoBroker is an object-oriented data maintenance system containing all information
relevant to the system. This includes measured values supplied by the monitoring
programs of the CentricStor components.
– GXCC and XTCC receives information from the various InfoBrokers and presents it in
graphical format.
– An X11 server provides any on-screen display requied and processes commands
entered via your keyboard or mouse.
These three components communicate with each other on the basis of the TCP/IP protocol.
The InfoBroker, GXCC, and the X11 server can thus reside on the same system, or be
distributed between two or three systems connected via TCP/IP. Please note that the flow
of data between the InfoBroker and GXCC is considerably less than that between GXCC
and the X server.
i
CentricStor utilizes numerous components, all of which are monitored and managed by
GXCC. There are several options for accessing these components.

and optional configurations of the user interface.
