Anyone using this yet and can comment about stability and flexablity I
have a new project coming up and IBM is proposing this technology I'm
not sure how reliable this feature is and if its even standard practice
in an AIX environment i'm coming from a Sun Solaris background the
closest thing we have to this is N1 grid containers which wont be ready
until Solaris 10.

I can not comment about stability because i have not any p5xx with aix
5.3 in my hands. But i can talk about flexability.

First of all. You have to have a need for micro partitioning like
server consolidation, running different kind of apps not in the same
environment, need for batch-jobs a.s.o.
The most advantage with micro-partiting is that your idl-time goes
below 10% because the ability from the VM to share process-power by a
1/100 of a cpu, 16 MB ( just from memory ) chunks of memory and also
virtulize disk and network i/o


A very very simple example:
20 2way Servers before with each has 2GB-Memory, 2*GB-Adapter,
2*FibreAdapter
which made up:
40 CPU
80 GB Memory
40 GB Eth. Adapter
40 GB Fibre Adapter

and a average load of 25%

Now you have a p570 with
16 CPU
64 GB
6 GB Eth. Adapter
6 GB Fibre Adapter

using virtuell i/o and micro-partioning
and a average load of 90%

I would wait not even one second to install and customize such a
machine ;-)
So go for it.

with kind regards
Hajo




Lets assume a simple environment

You have need for:
Webservice 24*7
Batch Processing nightly

Stability??? This is NEW hardware, firmware and software. Give it 15 months
and then ask about stability... just speaking from past experience with
670/90....

Hi,

I have a p570 already went productions.
The virtualizations functions are cool.

Can you believe that in my 4Ways p570,
I have 20 over partitions running, each has it's own OS
instance and OS disk space (rootvg) is only 3Gb.
3 networks card virtualized to shared across all the virtualizations.

I would think it is safe to use. The latest firmware
is very stable.

PS. Please take note. Sun Containers are actually
IBM WLM. Sun sales person came to me and try to sell
me their so-called virtualization but when I discover that
all containers are shared within a single OS instance.
I immediately give it a thumb down. You have to be clear
with the various vendors marketing strategy.

-Thanks.

What type of application are you running that can surive in 3Gb rootvg.
I guess an apache instance with all logs going to /dev/null could be
possible

However, they would need to be almost unused sites if you had only 3 pipes
for 20 webservers.

but what about next weeks release??
