Limitations of MSFT Exchange 2010

March 16, 2010

I am not sure how one of my goslings came across this spreadsheet tucked away on the Microsoft Exchange Web log. When I tried to access the file, the system did not recognize my “official” Microsoft MSDN user ID nor my Windows Live credentials. So you may have to register to access the blog. Once there, you need to look for the download section and visually inspect the file names for the one that points to the Exchange Performance Excel spreadsheet. Running a query in the blog’s search box produced zero hits for me. But with some persistence and patience I was able to get a copy of the spreadsheet. Latency was a problem when I was fiddling with this download. (Note: if the link is dead, write one of the goslings at benkent2020 at yahoo dot com, and maybe he will email you a copy of this document.)

Once you get the document “Scalability Limitations”, you will see some pretty interesting information. One quick example is that the spreadsheet includes three columns of specifics about scaling amidst the more marketing oriented data on the spreadsheet. These three juicy columns are:

  • Limitation
  • Issue
  • Mitigation.

Here’s the information for the row Database Size:

  • Limitation–Exchange 2007 – 200GB; Exchange 2010 – 2TB or 1 disk, whichever is less
  • Issue–The DB size guidance changed from 200GB (if you are in CCR) to 2TB or 1 disk, whichever is greater (if you have 2+ copies of the DB in question)
  • Mitigation—Blank. No information.

Okay.

I hope you are able to locate this document. For those of you eager to install Exchange 2010, SharePoint 2010, and Fast Search 2010, you will want to make sure you have these type of spreadsheets at your fingertips * before * you jump on the Microsoft Enterprise steam engine. The information in the spreadsheet makes clear why some types of email content processing may be expensive to implement.

This is the equivalent of the free newspaper Velocity in Louisville. Read it for nothing. I will report working for no dough to the Jefferson County agency that thinks I work in Louisville when I spend most of my time in the warm embrace of airlines.
