The FC Layer Model has 5 layers which have the following names:

FC Layer Model ➟
FCP
FCP, like FICON, is a protocol of the uppermost layer
the
which is exchanged between the application and the terminal, is mapped onto the
services of the lower FC layers.
FC Switch
An FC switch is the central component of an FC-based Storage Area Network (SAN). It is
capable of connecting each of the terminals which are connected in a star-shaped
configuration with any of the others and of guaranteeing a defined bandwidth for each
connection. The FC switches used for the internal SAN in the CentricStor VTA models
have 16, 24 or 32 ports.

The graphical user interface (GUI) contains the following two components:
GXCC:
XTCC:
GXCC
GXCC is the user interface for operation, maintenance and monitoring of CentricStor .
It is a program with X user interface which supplies a complete graphical image of a
CentricStor systems which includes all the connected devices and ISPs, such as ICP,
IDP
as a unit.
