RE: i5-520+ - Performance

I will add that we have been a very satisfied Performance Navigator
customer for years.

They offer a free download of Performance Navigator that allows you to
start collecting data immediately, so you will have a history of your
system if and when you do buy the tool.  The trial version lets you see
some CPU info and some other data, and the rest of the features are
grayed out.  Midrange Performance Group has also been very good about
giving out 30 day trial keys so that you can test the full version.  The
data is stored in a "compressed" format.  My Perfomance Navigator
library has 3+ years of data in 248 MB of space vs. QPFRDATA, which
holds 30 days worth of data using about 10 GB.

I have to agree with the previous post. You must run a performance
analysis to verify that your workload will not suffer if you decrease
the amount of interactive processing power available. I used to use the
MPG Performance Navigator on most system engagements when I was selling
System i. It is a fine tool for looking at all of the performance
related items on your system including processor, memory, disk, etc. You
must be collecting performance data for it to have a history to look at.
They can be reached through your business partner or at www.mpginc.com.

My gut feeling is that the 60/1200 will be just fine, but you should try
to
do some analysis of your interactive workload on the current 720.  You
should be able to get a good enough feel by just looking at the
interactive
oriented graphs available within the system monitors in Ops Navigator.
If
you are working with a business partner on shopping for the new box,
alot
of them will offer an analysis to help you confirm this (ours will
engage
the Midrange Performance Group, who will do a no-cost 'second opinion
service' that will help confirm that a hardware purchase is the right
hardware for the customer).

Unless you REALLY need a whole ton of interactive, the Enterprise model
will be a huge premium price to pay... this is worth doing the analysis
on
instead of buying the Enterprise model 'just in case'!

Hello,

we have a discussion about performance capabilities of the new i5-520+
systems.
We want to replace a model 720 with 120/240 CPW either with a 520+
Express
with
60/1200 CPW or a 520+ Enterprise with 1200/1200 CPW.
The problem is obviously about cost.
We recently added a HA package to our main system (this 720) and that
added
another
8 to 10% of workload which is now more than enough for that processor.
Main application is Movex 10A, running a lot of background processes,
which
would be
well suited for the Express model.
The question is do we NEED the enterprise machine or is it possible to
run
with only
60 CPW interactive Performance ?
We recently replaced a 720 with 70/240 CPW at another site with an
Express
i5-520+ with
60/1200 CPW and our experience was like: "WOW, what an incredible fast
machine !"
even with that smaller interactive feature.

Best regards from Germany,
Mit freundlichen Gr??en,
Philipp Rusch
