Server Sizing/Capacity Planning

[Albert Smith_1]

Greetings All -

I was wondering if there is any capacity planning and server sizing tools for HP-UX. We currently have Perfivew which will help us measure feature growth and overall performance. Is ther anything else that will help with this?

years of practice, but I haven't figured out how to write that tool yet. Basically you need a modeling tool and the only way I've been able to do that is to actually get ahold of a server and test.

Albert,

Measureware can do a good job if used properly. You need to configure the "applications" (workloads) that will help do an extensive study of the system. You can n measure the utilizations w.r.t each process/user or a collection of processes/users. This gives a knowledge of how your application is behaving and you can trend the server depending on the future forecasts.

There is one more software that I know of is BMC's BEST/1. This does a little better job than Measureware. This is purely a capacity planinng software. If you get an evaluation copy, you can try it. It's nice.

I use Perfcap's Performance Software solution for performance management and capacity planning. Their pawz tool gives me web-based automated and true cross-platform performance analysis data. Their PSS capacity planner gives me client-server modelling, saturation and predictive hardware analysis cross platforms. They are a lot cheaper than other tools, and works on HP10/11 ( + Tru64, Sun, AIX, Linux, NT/2000 and even VMS). The planner can also read measureware data (HPUX10/11)

The problem with any capacity planning tool is that it first must capture information.

If it is a new application I would refer to the company that supplied the app if it is 3rd party.

If it is a new in house app your best shot is to do some testing on a box you already have.

Do you know what apps will be running on your box?

We use SOS from Lund and their performance gallery gold product. Basically we use a baseline of performance and growth over time to predict when we need to upgrade.
