Again
ELA, that's licensing per core depending on your ELA can change.
again, depending on company and size. WAS for us was a moot point
as was Oracle, DB2 etc.. no software advantage
just stating it's not a blanket thing

Thank's, Yes they know, and are involved.
The win is due to pricing often is per CPU/Core.
Both SLES and WAS are licensed per CPU/core.
We need one license per IFL
and they also need one license per cpu/core in blades.
There are at least two cpus in each nowadays, so 200 servers usually means
about 400 licenses compared to one or two for one or two IFLs:s.
The pricetag differs yes, but far from that much.

FYI
Your company ELAs may have a impact on this so be aware.
Be sure you get you Licensing folks involved as they know the ELA's
better than anyone. In our case Software cost became a moot point due to ELA's
and
it became a HW battle.
The size of your company and how it's ELA's are structured could
impact this tremendously.

You can not just take the isolated cpu-hw-cost and compare.
Also include in HWcost all maint with HW, like connecting-power-cables-boxes
and so on.
With many blades you have to keep all these switches and cables in order. Just
the simple case
install a new server includes bying the HW, carry it into the server hall (you
will need authorithy which
often means you have to wait for the guy with the 'key') connect them (is
there enough power in you
diesel-backup?) add cables to a switch (which switch and who documents this)
and the installing.
There is some manhour here.
By now you probably also have a different box, not the same as the existing
ones, and you can
not guarante exact same hw, maybe different drivers for new
bios/network/disks/SCSI adapters......
Some customers requires exactly same setup for test-QA-prod, that may now be
hard to get.
Include all that and:
When you have 200 Linux servers, do the calculation, and you will se that the z
alternative
will have about the same hw-cost as x86 blades.
If you also include the license costs, the z maybe comes out as the most
cost-effective one.

In my Linux Installation Planning talks, I address this briefly. Until such
time as IFL processors cost the same as Intel processors, i.e. never, there
will always be some point along the spectrum of workload profiles where it
makes more sense to run a given application on midrange hardware and not the
mainframe. With the introduction of the z10, that point has moved
considerably, in favor of the mainframe. There is still going to be a
substantial grey area before that point, which is why each case needs to be
examined individually to make the correct decision.
Amen !
