I want to calculate upstream and downstream bandwidth for my exchange 2010 servers. based on these calculation i can get appropriate bandwidth from exchange 2010 servers.

The only related info I can find is for Exchange 2007, maybe you already have read it http://msexchangeteam.com/archive/2008/04/10/448668.aspx Jonas Andersson MCTS: Microsoft Exchange Server 2007/2010 | MCITP: EMA 2007/2010 | MCSE/MCSA Blog: http://www.testlabs.se/blog

Hi Jonas, actually my question is more towards the network traffic on my edge servers which actually exposed over the internet, i am deploying Exchange 2010 in my environment and my network team need to know the actual bandwidth requirements from my side so they can acquire more bandwidth for this new solution or readjust from the current pool. Inbound/outbound smtp traffic calculation what I need to know.

Hi, As per my understanding to your question you have to figure it out manually and for this you have to follow the steps given below but I M just explaining you as per my practices these are not standards. 01. Users = 1000 02. Mails per user = 10 03. average attachment size = 1 MB Than your calculation should be like this 1000 x 10 x 1 = 10000 MB per day / week / month as per your requirements. I hope this will help you. Regards. Shafaquat Ali.M.C.I.T.P Exchange 2007/2010, M.C.I.T.P Windows Server 2008, M.C.T.S OCS Server 2007 R2, URL: http://blog.WhatDoUC.net Phone: +923008210320

Hi, First, you need to know the average number of mails sent per day, messages received per day as well as the average message size. You could use message tracking log and performance counter to obtain the related information. Then, multiply them together just like: (Avg num recipient domains/msg) x (Peak Avg msg/sec) x (Peak Avg msg size) x (8-10 bits/byte) = peak dedicated bandwidth Related article for your reference: Company Network Requirements (Exchange online part) http://technet.microsoft.com/en-us/library/cc745931.aspx Client Network Traffic with Exchange 2007 http://msexchangeteam.com/archive/2008/04/10/448668.aspx Thanks, Elvis
