Even with more, smaller servers, I'm not sure how small the connecting population would have to be, per server, to get away with less than 8 GB of RAM on a mailstore.  We'll probably be adding two more LS41's to the mix, in order to give folks a warmer fuzzy about capacity, but we're really not doing too badly, right now.  We just don't have a lot of extra capacity for unexpected demand peaks.  But, we are delivering around 300,000 messages a day to the complex, and supporting peak usage accross the complex of about 6,000 concurrent connections.

How are backups going for you?
