RE: Upgrade existing machine or buy new?

170's max out at V5R3
270's max out at V5R4

Power 5's have no max at the moment.

But like a few of the earlier posts, a new single core POWER6 520 is going to smoke any of the above in performance and it's fairly "inexpensive",
comparatively. It's also in the lowest software class, P05.

Isn't a Model 170 a dead end system? I.e., isn't the highest O/S level it can run V5R3 or R4 (or earlier)? All other things being equal (and they
never are, of course) this would be the tie-breaker that would push me to get a new machine.

Hi everyone,

I have a customer that has a 9406-170 with 256MB main storage and 25.770GB
disk storage. This system is fine for the 25 or so concurrent users most
of the time. Now we are going to install a web application using Zend.
When we run our web app on that system, it is too slow. The customer is
considering a new System i for this reason. What would be the best use of
their money, buy a new System i or upgrade the RAM and add more disk?

They currently are as near as makes no difference to 100% disk usage. The
daily close and backup is taking about 40 minutes longer than they would
like. They are on v5r3m0. An important software factor when considering
v6 and beyond is that they are heavy users of WRKQRY and that isn't going
to change.

Best suggestions?

James Rich

if you want to understand why that is, there are many good books on
the design of operating systems. please pass them along to redmond
when you're done reading them :)
