●
Linux/Windows pool
This pool exists only if a XenVM license is installed and when sufficient CPUs are
available. It is used exclusively by XenVMs.
●
Depending on the hardware and licenses which are installed, further unused real CPUs
can exist in the Server Unit outside the pools, the so-called
free CPUs .
The CPU pools are also visible under VM2000, but the naming of static pools is retained in
VM2000 for compatibility reasons. The table below shows the names of the CPU pools in
the X2000 basic system and the names in VM2000.
In normal operation enough CPUs are available for every pool. A lack of CPUs can occur
in the following exceptional situations:
●
Reduced operation: a hardware failure means that fewer CPUs are operational at
system startup.
●
Abnormal operation: a change of license means that more CPUs are required.
