I don't see the two statements as totally contradictory, though the one I
referenced was later than that you referred to.

What's needed is a document that covers:
- minimum physical drive required for a hardware partition
- minimum size that can be allocated to a storage space for a guest

Having to create a partition of 420gb or better as a minimum requirement is
overkill if you want to really be able to take advantage of the
virtualisation capability.

You need to be able to be creating partitions down around the 150-200 gb
mark otherwise the storage requirements balloon out,

Given that you have enough memory, based on those minimums you'd need
around 5TBs of storage to create a host with 9 guests. (That's based on
allocating 400Gb to each guest and running the host at around 70% full; all
partitions allocated .1 processors. That amount of storage could get hard
to explain, especially if all the environments ran at 30 or 40 per cent
utilised in terms of disk.

I realize that's an extreme example but if (for example) you wanted to
build out a dev/test environment with a lot more environments that's not
totally out of the question these days

On guested partitions the rule of thumb is
- six or more virtual disks
- of a consistent size
- keeping in mind the 70 GB future minimum size
Corrections or suggestions by better minds than mine are certainly
welcome.

You know, if IBM would just update this site:
http://www-947.ibm.com/systems/support/i/planning/upgrade/future.html
officially all would be better.

Trust me, I brought this up while in Rochester last week. With
suggestions that the sooner they get it done, the sooner people could get
it in their 2014 budgets. Therefore the sooner IBM could cash the check.

This is interesting.

Late last year Sue Baker recommended on this list a load source of 25gb or
larger, and made a point of differentiating between physical disks and
virtualised disks. See this post:
http://archive.midrange.com/midrange-l/201209/msg00500.html

I realize this list in not an official IBM channel, so I am not
complaining
about the difference between what was said and what you are saying. Key
thing I think is that the minimum disk size for a guest *might* be smaller
than the 70 GB but this is the smallest physical disk that will be
allowed.

Maybe we need to go with 40 gb or some other size when configuring a
storage space for a guest partition.

That is true. Also note that 7.2 will require a load source that is
70GB
or higher, and right now the min is 17GB so that is a big jump and
people
should start planning for this now.

Would guesting 7.2, either
- on a host 7.1 partition
- or on VIOS
insulate you from the above statement? Granted all affected I/O (disk,
tape controllers, etc) would have to either be on supported hardware or
be
virtualized also.

Steve Will responded with these corrections:
===================================================
The next generation of servers following POWER7® / POWER7+™ is not
planned to support IBM i 6.1 and will require IBM i 7.1, or later.

[IBM i 7.1 partitions]->(BECOMES)->: The release after IBM i 7.1
will run on POWER6® and newer hardware. No POWER5 technology-based
systems are supported.

[IBM i 7.1 partitions>->(BECOMES)->: Partitions with the release
after IBM i 7.1 cannot own any HSL/RIO or IOP hardware, but they can be
virtual clients. (This support statement was already true for POWER7 and
later. This planning statement specifically applies to POWER6
technology-based systems running (ADDED)->[the release after] IBM i
7.1.)

Language Translation Support: Starting with (ADDED)->[the release
after] 7.1, the 5770-SS1 IBM i operating system and subsequent products
will no longer be translated into Croatian and Romanian. The national
language version feature codes for Croatian (#2912) and Romanian (#2992)
will remain, but the text will now be delivered in English. The system
multicultural support for these languages will not be affected.

======================================================
So effectively there was some 'oops' where IBM i 7.1 was used where 'The
release after 7.1' was intended.

Also if you missed it, Colin Paris indicated that 'The release after IBM
i 7.1' would be known as 'IBM i 7.2' and is expected in 2Q14.

AFAIK IBM i 7.1 ran just fine on my test 520. Does this mean that
starting on TR7 the LIC wont load on such systems? or is it an
attempt
to move people off the old hardware?


Just a thought...
