1536MB
NOTE: Systems with low main
memory (less than 2GB) might not be
able to allocate 1536MB of memory
to Java, due to which the Java
application will not start. In such a
case, it is suggested that you set the
heap size value to an MB value lesser
than 1536MB or use the default value
set on the host system.
> 30,000 LDEVs1
Set Java heap sizeNumber of LDEVsManagement Station
