RE: No Power7 to Power8 MES upgrade option, entitlements, cores, etc.

Charles,

We average 1200 active jobs.

From perf data, processors used, normally .2

Occasional spike will take it to .6. or .8, almost never to 1.0
This includes some heavy batch usage.

There's a apparently statement of direction (SOD) for MES upgrades for 770 / 780(?)

Also while an individual job, even a mutli-threaded one, would stay on a single processor..

Multiple jobs should be spread out among CPUs...if you're not seeing that, something is wrong.

1) Is IBM doing away with MES upgrades?
No MES upgrade path from Power7 to Power8 Over the years, IBM always
gave you an upgrade option, up to a point.
If you upgraded within that timeframe, you saved $$$$, if not, the
new machine would be quite a bit more, you lost all value from old machine.
This is what kept you current.
We had our same serial# for over 10 years from our original 510 (mid
90's) Also, on MES, all entitlements would transfer.
On a new machine, the base entitlement had to stay with the old
machine, so you had to repurchase an additional entitlement to remain
at the same level.

9406 AS/400 RISC Series Processor was our original 510. (mid 90's)
9406 System Unit MES # 19262 from 510 to 640 upgrade. (2nd quarter 98)
9406 System Unit MES # N26616 from 640 to 830 upgrade. (2nd quarter
2001)
9606 System Unit MES # 129707-6 from 830 to 550 upgrade (3rd quarter
2005)
8205 new purchase - (1st quarter 2012)
S814 new purchase - TBD

2) Also related to number of cores.
We currently have an 8-core 8205, but only 3 cores licensed for i5/os.
The remaining 5 active cores are useless.
We needed to purchase them to get the 8205 features we needed.

I see the same issue, but only worse with Power8, number of cores has
increased.
Also, not sure if many know this, but if you have more than 1 full
processor allocated to an LPAR, and your running RPG or RPGIV, that
2nd processor will probably never be used.
RPG and RPGIV is all single threaded, most work will always only use
the 1st processor.
Way back on Power5, our BP sold us additional processors with the
perception that more work will get done quicker, not the case.

Thank You
