RE: i5 Youngsters

Are the Windows servers doing the "One App One Server" approach? That's
still a lot of server OSes to maintain (i.e. patches). I have also seen the
many LPAR approach taken in i5/OS shops also though - it lessens the chance
of stepping on other apps toes I guess, though you end up with more OSes to
maintain (again).

We all know Windows and i5/OS are both capable of being more than a
One-App-One-Server machine, but it is interesting to see how companies are
reasoning away from that approach.


BTW, that _is_ quite the impressive setup you have there! Would be
interesting to hear pricing on your setup if you are able to divulge.

Apart from VMWare for servers I have often wondered about using VMWare for
developer machines to get them up and running with necessary software on a
fresh OS in less than 10 minutes. I believe it would be as simple as
copy/paste one VMWare session file to another, right?

Having just put VMWare through it's paces next to a beautiful i5, I can
wish for VMWare on the i5. Right now, there are 2 - 4 way IBM servers
running, with 40 GB RAM connected to a SAN. 17+ windows servers run on
the hardware with dynamic, live failover between the boxes. Citrix is
running on some of those servers. All desktops have iSeries Navigator
running. Truly a mind bending assembly. The underlying OS for the
VMware is Linux. Makes one think about i5 possibilities.

Best regards,

Note that I have NOT done the multiple LPAR thing, but am simply acting on
what I have read. Yes, I know that is dangerous, so thanks for any and

all

light anyone can shed.

Can you control/share resources on multiple pizza boxes like I believe you
can on the iSeries? Can you get processing on demand? The amount of

power

consumption would be less more than likely - that is something more
organizations are starting to consider. I am sure there are other

benefits

that I am not entertaining.

I guess I would like to ask you the same question as you seem to like the
multiple pizza box approach - what is it that you feel makes them better
than System i other than price?

2) And now, for all your reasons given for #1. Can you do that w/VMWare?

To date my experiences with VMWare sessions has been limited to some
business use, but mostly personal use. I think a VMWare vs. System i LPAR
would be a great article for somebody other than myself to write - I would
read it.

I do see value in having all your processes/servers running on a
single machine using multiple LPARs.

1) OK. What is it? Seriously. Why would you prefer a single machine
w/LPAR to multiple "pizza-box" servers?

2) And now, for all your reasons given for #1. Can you do that w/VMWare?
