Forefront protection for exchange 2010 Installation and design Step by Step

I love forefront protection for exchange it probably the most successful antispam well if it sized correctly Smile .

performance considerations

to simplify a lot of reading for you its about 64MB per Engine per process( process means the how many emails will you be able to scan at specific time so 2 means two emails at once , or 4 emails at once …etc. ) so if you are using 5 engines you will need 320M to scan a single process + at least 650MB to support the services also double his values if you have two roles installed (HUB, mailbox ) .

note :

Less memory is required if Intelligent Engine Management (IEM) .
if you get a lot of emails with large attachments you have to increase this members .
you should install FPE on all Exchange Servers that you have ( Edge,HUB,Mailbox)

so for server with 4cores scanning using the 5 Engines running 4 process this will need 6G of Ram for best performance scenario but the minimum requirements for FPE are +2G of Ram

you should always use " Forefront Protection 2010 for Exchange Server Capacity Planning Tool " http://www.microsoft.com/downloads/en/details.aspx?FamilyID=2303c87d-f976-4424-a192-24d2af02064d&displaylang=en

so what is the lab environment I am using? its not a big environment but it’s the most common

note; we will not be covering TMG+ Edge in this post as it already covered in Email Protection with Threat Management Gateway

installation notes

Network Load Balancer (NLB), there are no special installation procedures for FPE
You install FPE on LCR and DAG systems just as you would on a standalone system for other cluster types please visit http://technet.microsoft.com/en-us/library/dd639348.aspx
