Scott- Just from personal experience: 1-At least 2 gigs of RAM 2-Dual processors 3-Mirrored drives, OS, Pub, & logs on one set. Priv on the other set. I understand that this is debatable, but I have been very happy with the performance. 4-DB size is critical so if you're running standard Exchange, the drive set (Raid 1 or otherwise) for the Priv should at least be 36 gigs in size so you can do an offline defrag if necessary. Current Dell 2500's are pretty good if you are familiar with Dell's. Minimum Processor speeds, L2 cache, & FSB speeds are more than adequate for an Exchange server with 160 users. 5-Even if you do get permission to lock down end user mailboxes in terms of size, I'd still try to persuade your client to go with the Enterprise version of Exchange. But I know that budgeting will play a big role in their decision making process.

Obviously if you go with standard, you'll need to limit mailbox size accordingly to avoid maxing out the database. I supported 200+ users on Exchange 5.5 standard for some years without many problems; you just have to keep the "power users" under control. It really comes down to how they use email; if they have a lot of heavy email users who send and receive a lot of attachments, enterprise version might make sense.

We have a customer that would like a Exchange system for 160 users. I am not sure if Standard will work or if they will need the Enterprise edition. I am aware of the 16Gb store limit for standard edition. Just wondered if there is a formula for the different versions.
