RE: Capacity on Demand: memory issue

Rob,

Your supposition is correct.  The below is taken from an IBM V5R2
presentation on Capacity on Demand, note the footnote.

Processor-on-Demand             Units of Processor Capacity
Memory-on-Demand                        Units of Memory Capacity*
Disk-on-Demand                  Units of DASD Capacity*
Interactive-on-Demand           Units of 5250 Interactive Capacity*

* IBM is currently evaluating for a future iSeries release.

Presentation source is:
http://www-1.ibm.com/servers/eserver/iseries/hardware/ondemand/
and requires Lotus Freelance Graphics.

The question of whether the customer will have downtime is more related
to concurrent maintenance than to whether the item is available on
demand.  As far as I know, installation of memory requires a
powered-down machine.  Some features can be added to the newer platforms
(PCI cards and DASD) without powering down, but memory is not one of
them.

Andy Nolen-Parkhouse
