Financial contribution:
The zCOST concept reduces the
MSU basis and so it has a
tremendous effect on the IBM
software bill.

The zCOST flexibility also allows
 to extend the life of the current
 hardware configuration thereby
 avoiding millions of dollars in
 hardware and software upgrade
 costs.

Technical contribution :
Allows to redesign inefficient image
configuration dynamically or
statically

The large datacenters are the
most likely to need such flexibility
as they are constantly balancing
workloads around to make the best
use of limited capacity during
peak processing times :

zCOST gives it !
