Recommended MDS Capacity & Resiliency

[Rizza]

Hello my first post here.

We're planning a blackberry production service with MDS installed on a seperate server. We'll have less than 500 users initially and ultimately crank up to 2000+, however I'm unable to find recommended capacity figures for the MDS, can anyone advise or provide me with a link to documentation with this information.

Furthermore, does anyone have the MDS server in a load-balanced configuration?

Thanks

Rizza -

Welcome to BBF; what aspects of MDS are you going to be using? Just the MDS CS? MDS Services?

The Capacity Calculator (http://www.blackberry.com/btsc/dynamickc.do?externalId=KB13777&sliceId=SAL_Public&command=show&forward=nonthreadedKC&kcId=KB13777) is pretty good for a start.

Thanks for the link hdwag, initially we'll just be using the MDS CS service only, and the spreadsheet suggests our sizing is more than sufficient.

For the basic MDS connectivity I still have it hosted on the same box as the BES. We are running around 1,100 users on one box and 980 on the other. Internal applications (Bloomberg, Pyxis, G2X) are being used by 75-100 users and I've had no issues.

Thanks for posting this; not too many people do anything with internal apps so its good to see some benchmarks.

What are the specs on your servers?

Both are blades (AMD Opteron 280's) 4 ways with 4gb memory. SQL is offloaded to Enterprise SQL server (2000 SP4)
