CPU and RAm requirement

I have been looking for info regarding the CPU and RAM requirement for Web/App/DB server for E811. I am looking this info for about 200 user . Also at this stage we haven't narrowed it down to what architecture we will use (INTEL/NT/SQL , AS400 or Orace/DB2). Do you guys have any info on this.
I would greatly appreciate any help on this.

Nick,

you can get any authorized hardware partner to do this for you and price it out.............that's their job!

We're authorized to size on all IBM platforms but you're not likely in our area so we couldn't sell to you.......thus no benefit to us. Not that I wouldn't want to do it but the sizing process does take a fair amount of time to do properly.

The best sizings are done by IBM......not that you have to buy IBM. After all a 3.0 GHZ Intel CPU is donna do pretty much the same think regarless if the box says Dell, IBM or HP.

Colin,

Thanks for the reply. We are in middle of a proposal. So at this stage we are just planning and looking into this requirement. I was just hoping someone will have some good practice doc for this sort of configuration. Ofcource when we are ready for the actual hardwarepurchase this will be re-evaluated along with the hW vendor

I agree with Colin...regardless of what "stage" you are at, any, I repeat ANY sizing estimate, guidline, guess, divining, shot in the dark, etc. should be done by your hardware vendor. If you are unsure of platform, get sizing and pricing from vendors of all platforms you are considering.

For installing E811 on your system, you need minimum 512 RAM and to make it run on a gud speed, put 1GB RAM

Don't wait.........size now. It doesn't cost anything. Try and find a partner who is a JDE partner and a hardware partner of IBM/HP/Compaq. Since they sell and service JDE and the hardware they'll be able to give you the best "real" recommendation.

Of course only IBM can give you all 3 sizings.

Be very careful with sizings since it's hard to compare. Some configs may put everything on the sma ebox while others may put in many seperate boxes.

I wouldn't talk to any vendor that didn't suggest a SAN if on Unix or NT. iSeries with the new i5 rocks for performance.

Once you get a sizing you can post the results and ask questions and all us academics can have our long awaited next "platform" holy war.

Nick,

Picking your platform is a pretty important first step. Until you have that decision made, you'll be comparing apples to unicycles. If you do a search on this site, you'll see some of the issues discussed in picking a platform. In my opinion, a major deciding factor in picking a platform is your existing IT skill sets and other IT platforms in your shop. If you guys have windows and MS SQL for your other servers and databases, then go that route. If you have AS400 experience and hardware, go that route. This stuff is not set and forget. It requires a lot of expertise to manage. That factor needs to considered.

Once you have a platform, THEN you can talk sizing. I would suggest talking to a few vendors. As Colin said, that part is free since they are trying to get your business. have fun, I'll look forward to the next platform "holy war!"

Re: CPU and RAm requirement and Custom Mods

Hello Nick,

I did some sizing myself on a AIX/Oracle/Citrix platform a couple of years ago here. Here's some of my experience that I want to share with you for your decision making process...

We're running 40 locations with a maximum of 250 concurrent users with approx. 10.000 business transactions per day. I configured, only for PRD, 2 AIX servers (S85): One Oracle server, 12 CPU's, one JDE server 8 CPU's, both 24GB memory, all data on a clustered NetApp NAS system and a Citrix farm of 10 Dell 2850's.

Any hardware vendor (including IBM) will tell you that this is WAY oversized given the amount of concurrent users and transaction figures (so did I), but in the end... it doesn't perform. Sometimes minutes response times for end-users!.

The culprit appears to be in the custom mods... At the beginning of our implementation, we first started off putting approximately 20 man-years of JDE custom development in our system before rolling out the first site. The first site went live, 25 users, no data yet, performed like a rocket, so far so good.

As more and more sites went live, the data grows, the amount of users grows, the technical efficiency of your applications becomes more and more relevant.

And... if you have 15 'functional' developers clicking away for 2 years without worrying about performance, the system that results can in no way be compared to 'JDE out-of-the-box'. Believe me, we had every Oracle DB-specialist, AIX specialist, CNC specialist money can buy here, but they all came to the same conclusion: "The problem is in the application, not in the HW, DB, OS, network"

So my advice is: consider the amount of customization that you expect in the sizing of your hardware. Furthermore, make sure that the development process contains technical reviews of the generated code/queries. If not, you will definately end up having an undersized system with corresponding performance problems.

Quote from Oracle-JDE specialist: "If you develop in JDE without worrying about the code that results, it most likely will have a significant negative effect on the performance"

Hope this helps,
Lambert

Hi Lambert

Thanks for your response. I am aware of the problem of poorly written application will nto perfom in best of the system. Hopefully we will keep these experinces in Mind.

In any case, thanks for sharing your config with me.

I really appreicate it.
