Hi All,

Im after some recommendations/knowledge on implementing a Multiple BES Setup on a Blackberry Domain. i.e. Have a BES in Australia and a BES in the Sweeden. Can anyone provide some working examples aswell as any tips/guidelines as to what issues you have encountered.

I'm also looking at putting a BES in other locations if this works out well.

Does anyone here have more than 1 BES in their environment ? If so what documentation do you recommend ?

Thanks in advance

Also.... can anyone provide the ping times between the BES Servers and their Exchange Servers that they have users on for that BES. Just want to compare as ours are reporting 300ms which is way outside Microsoft Recommendations.

Anyone ?

Bump?!?

I'll bite.

We have 2 BES servers and over 7 Exchange servers however our BES servers are setup to communicate with 3 servers only, and here's why.

RIM states that you cannot have have latency over 40ms between BES and Exchange. We have 3 Exchange servers and 2 BES servers in North America. 1 BES handles 2 Exchange servers (Pacific and Mountain) and the other BES does just the East coast. We initially had just 1 BES for all of North America until 6 months ago (roughly) when we were hearing of bad/poor/degraded service for just Eastern users. The pings from our BES to the Exchange server in the east was in the 130+ ms range whereas the pings for our Pacific Exchange server was 15-25ms and the Mountain server was <1ms due to it being in the same office. Once we installed a new BES out east, all our problems went away, nearly instantly.

Our Pacific Exchange server just happens to process email for certain South American countries and they work just fine because the latency is low even if the device isn't close to home.

To get this running, we setup the BES' to share the same SQL database so we can move users from the current BES to the newer BES without having to re-activate those users. It's a great feeling to move a user and have them report that it's working better than it ever did.

For additional info, we have 330+ users on the shared database with one BES handling 2/3's the user load. Our Exchange servers handle email for 4000+ users and are also setup with SP2 so we can get WM5/6 devices to work as well.

Hopefully this helps and I didn't ramble on too long.

Thanks Ordeas, I knew there were some big playing BESAdmins out there....

You stated the following "To get this running, we setup the BES' to share the same SQL database so we can move users from the current BES to the newer BES without having to re-activate those users."

Was SQL ping time an issue?
