Deploying BES 5.x Planning Sizing help

[Tacfire11]

I'm looking to deploy a large BES implementation with Zimbra. Having trouble finding a planning guide guide for the the design effort. Traditionally, under other messaging Platforms (Exchange, Notes, Etc.), BlackBerry Enterprise Server will accommodate 2,000 Users per Server. I am planning on deploying Zimbra and 22,000 BES Users. Will the Zimbra BES Connector support this same capacity as with Exchange (2,000 Users)? Does anyone have any design experience or reference material they can recommend.

Thanks

Wow 2.000(!), let me know what Zimbra states! In your case I would keep in mind that ZCB relies on a local Outlook to work. Speaking to the official Zimbra guys about that might be a good idea - Outlook is certainly not the most stable solution... although ZCB became much more reliable over the past 12 months! I only run 20 users on my BES.
