Larry,
I have 5 cores, 4 TB DASD, would have to move memory from Production, could be an issue.
Where do we obtain the Linux DVD from?
Linux support - how and from who?
From our 2012 config.
5639-RH4 Red Hat Enterprise Linux AS 4 0000KP403 1 N/C
2802 1-2 CPU 1-Yr Std Subscr only, no support 1 395
=========
5639-RH4 Price 395
5765-AVE IBM PowerVM Lx86 for x86 Linux
1 Per server

Of course "It Depends" :-)
Absolute maximum Linux partitions on 5 cores of POWER7 would be 50
POWER7+ or 8: 100.
Depending on what you're doing with the partition you could in fact run as low as 256M of memory but 1G is a nice start.
Personally I never install gut GUI on a linux server partition but that's a preference. Command line only.
Can quite easily make it run in 16GB of disk.
Supported is SLES and Redhat. With Power8 add Ubuntu.
Also OpenSUSE 12 is available for Power as well.
For the console I almost always use the HMC. Log in with SSH and then use 'vtmenu' and select the partition from the list.
I load the Linux install DVD to the host partition and boot from that over virtual SCSI.

5 active non-i5 cores.
How many Guest Linux LPARs could I create?
How much CPU, MEM, DASD would a single Linux LPAR require.
These would all be hosted from my R&D LPAR or my Upgrade LPAR.
We had 1 Guest Linux LPAR hosted on the R&D LPAR back in 2006 on our Power5, only as an experiment, never went production.
It was a bear to configure back then, I'm sure it got simpler.
Getting a current Linux OS cd, console, and install of the dynamic RPM were the main issues back then.
I know nothing about Linux, am I too old to learn.
I probably need "Linux for Dummies"

This behavior of not all components being available with some sockets unpopulated is industry standard. Try to fill all the memory DIMM sockets on a dual processor board when there is only one installed for example!
Of course you are correct that you may purchase more processors than needed strictly for workload initially but look at the consolidation that can happen with that extra capacity! True value in that.

I guess years back the older gear kept a higher trade value for the used market, probably not case because things are changing so fast.
When our CE was here this week, he told me there still using/installing P4 in 3rd world countries.
I'm using 3 of the 8 for i5/OS. The other 5 are active cores, but no i5/OS license.
BP originally tried selling me a 12-core, but I found it could be done with an 8-core.
You almost have to be your own SE.
I see the issue with Power8 coming.
If you want the 11 PCI slots or the higher memory cap, which we probably will, you need to buy more cores, ever though we will not license.
1 socket S814
§§ 6-core
§§ 8-core
2 socket S814
§§ 6-core or 12-core
§§ 8-core or 16-core
§§ 24-core

Aha, you are confusing the parts you purchased vs the parts that go back to IBM in an MES. They can only count the stuff that comes back so processor box (CEC) and CPUs and planar board and whatnot. All the stuff you keep doesn't count and if you keep it that's because you perceive value enough to keep it. That's why they can't get to the number.
I don't think you got snookered, sure some BPs aren't as honest as others and some do 'creative' things to bend IBMs rules but when it comes to IRS type things they can't really cheat that.
These days 1200 jobs are not really that much either. My lab server with JUST ME and the *ADMIN server running (No printers either) has 207 jobs running.
So at your next upgrade leverage this information to purchase fewer cores to save money. Sadly you can't transfer those cores to anyone else.

I'm confused on the P7 to P8 that P7 would not qualify from IRS standpoint. I would like to see those IRS numbers.
Almost all my current P7 features will migrate to a P8, so that statement doesn't make sense.
So there stating that my current P7 value is less than 20% of
300,000
(60,000) Back when I went from P5 to P7, yes it did, nothing migrated.
So maybe we got snowed, or someone got a piece of one of our P5 to P7 transfers.
Maybe P5 rules were different.
As far as a 2nd processor being used, it amazes me too. I'm sure with a different mix, more Java and more SQL, then yes.
I wish I could show you a MPG graph, cores used.
I questioned this with IBM and several others years back.
They said purchased processors that you really don't need.
There is no setting to force the usage of additional processors.
Does anyone have Power gear with active processors with no licenses. We have 5 active cores out of 8 sitting idle.
Can't really use those cores for anything?

They are always working within the rules.
Jim is right on the IRS part. I believe the stated rule is that when you return your old system it must retain 20% of it's initial value in order to qualify as an upgrade. They could not meet that standard with POWER7 to POWER8 on the low end. Potentially on larger servers later as was also mentioned.
This is really a statement of how fast the industry as a whole is moving forward. WHat was 'state of the art' just a few years ago is now below 'ho-hum' in many cases.
As to IBM i licenses that rule hasn't really changed. Yes there used to be certain licenses that were part of the base box and as such were 'welded' to that server. When you upgraded you could not transfer those base licenses. Often this didn't really hurt much as the increase in CPW per core has frequently meant that fewer cores were needed and in other cases the drop in P-group more than made up for it.
With POWER7 and I believe PWOER6 as well there are no cores that are 'base' and so what you have should transfer to a new server.
Your expectation that no more than one core is used is out of the ordinary for sure. Back when we installed the very first 2-core machine in my customer base (a model 310) their constraint was single thread RPG batch so we wondered if the second core would do anything. Turned out both cores maxed right out, likely one running the RPG and the other doing I/O and DB work plus the O/S code.

That's not totally true on transfers. When we went from P5 to P7, new purchase, only 2 of our 3 i5/OS licenses would transfer. One had to stay with the old box.
So we had to anity up (44,000) and purchase anther i5/OS license to keep us at 3.

Keep in mind that IBM does not always have the ability to offer an upgrade with a same serial number option. Reason: Internal Revenue Service rules.
If the new asset is sufficiently more powerful than the old asset, IRS requires a new serial number so they can get their skin out of it in the new depreciation schedule. I think that is the situation with the current batch of P8 boxes.
Even when the serial number changes, IBM will transfer your software to the new box and since that's the biggest dollar value of the deal (usually) it's not nearly as bad as it used to be.

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.
