Our zVM licence has been recently cancelled, and I have just had

only pay for one copy. However, if you have many, one copy products, you end
up needing more engines on the IFL, which (if you get charged by the engine),

One problem of trying to get a cost per virtual server was always trying to
estimate how many servers an IFL will support. We had a 13 SuSe servers defined
in a z800 IFL but as they were hardly used we couldn't measure a thing!
So are there any rules of thumb out th
or government initiative expressly permitting the use of e-mail for such
purpose.

When we startup/initialize WAS Version 7 the IFL goes to max CPU, the

This is just during WAS initialization. The application that are being

a z890 IFL vs. a z10BC IFL

Rich: To be clear, the "list" price of an IFL (or zIIP or zAAP)
on a z9 BC was $95,000 USD and now on the z10 BC they are $47,500
USD.

The announcement said specialty engines are $47,000, not including ICFs.

The new z10 BC is stated at doing about 50% more workload at half the price.
On the z890, the list price for an IFL was $125K.
I seem to recall that the list price for an IFL on the z9 BC was somewhere
around $96K (anyone know?)
So, would that make the list price for an IFL on a z10 BC under
I didn't need a full throughput benchmark, nor did I need to benchmark the I/O
subsystem or the tape drives. The boss asked a specific question about the CPU
power. I found a program that answered his question to his complete
satisfaction. Now if he had asked for a throughput benchmark, an orchestr
upgrade our processor, just after our Performance and Capacity Planning
group was disbanded. So on an idle system, this just gets into memory
and runs with a high Total/Virtual CPU ratio. On my z890 IFL, 20
iterations takes about 8.571 sec virtual, 8.578 sec total and 8.944 sec
elapsed time.

Not everyone has the time, budget, management patience, or whatever to
do what is needed to get around that.

Here is good site that lists some performance guesstimates. Remember
that the specialty engines run at full speed. So in the case of a z/9 EC
the
IFL can be compared to the engine on the model 701, on your z/900 the
engine can be compared to the model 101,1C1 or 2C1 depending on your
current model
