GXCC/XTCC can also run on SINIX-Z/Solaris/LINUX/Windows systems which are
independent of CentricStor. In this case, GXCC connects via the LAN to the RequestBroker
of the ISP referenced in the unit selection, exchanges information with it and, on the basis
of this information, builds the graphical display.
GXCC/XTCC also covers the CentricStor components that can only be monitored via
SNMP, such as the Fibre Channel switches. During configuration, you define the ISPs in
which the management station is to be started. In addition, an SNMP agent can be installed
in CentricStor that permits CentricStor to be monitored by an SNMP management station.
