Server Sizing Suggestions

Hi,

I am looking to size a Notes 6.5 application server for about 800 users. The server will be running 3 major business critical applications, and some add in tasks.

The applications are very large workflow apps with multiple databases (up to 20 per app)…

The applications also make use of a lot of agents so agent performance is important. The servers will be running on WINTEL platform.

I am considering a 4 processor Netfinity, with 2 gig of ram…

But, would welcome any suggestions on ram/cache/disc types processors…

Thanks

Neil

Hi Neil,

Oh, I always love these server-scaling questions :slight_smile:

Go for a 4 Proc Intel Xeon 3+ GHz. If you can afford it chose a processor with 1MB cache instead of 512KB - this greatly improves performance.

You will need to fill it up with 4GB RAM.

Use a RAID-10 (0+1) configuration. Avoid RAID-5 - it’s way too slow!

I would suggest the following disk configuration for optimum performance:

OS + Programfiles: 2 disks RAID-1

Data: xx disks RAID-10

View_Rebuild directory: 2 disks RAID-1

Translog disks: 2 disk RAID-1

That configuration will really kick ass…

Remember it is really important to finetune Domino as well. Running the right number of amgr’s, replicators aso…

If you are going for the Xeon procs., I would recommend you to use W2003 as the server platform. It will give you 30-40% more scalability using the same hardware.

Good luck!

Thanks for that… its sort of along the lines I was thinking about… nice to know I am not too far off.

Will looking into RAID configuration - nice tip, will also investigate win 2003 platform

You may also think tips regarding software…

First, you can eliminate full-text search for those dbs that are never searched.

Also, if there are applications containing attachments, you should consider compressing them. You can try ZipMail at www.mk-net-work.com.

Hope this helped.
