Already being tested by 3.5 million users and aligned with Microsoft's software plus services strategy. What I find fascinating is that Microsoft found the cost of running Exchange 2007 to be roughly half that of running Exchange 2003. It is thought that E14 will bring that cost down by a similar margin yet again.

In order to assist customers in designing their storage layout for Exchange 2007, Microsoft put together a calculator that focuses on driving the storage requirements (I/O performance and capacity) and what the optimal LUN layout should be based on a set of input factors.
The Mailbox Server Role Storage Requirements Calculator has recently been updated to version 16.3.

I am a little surprised that there has not been more noise made about this.. thought I would do my bit as I am a totally against internet censorship..
The Australian Federal Government is pushing forward with a plan to force ISPs to censor the Internet for all Australians. I can think of several, non-technical reasons why this is a really bad idea.. for all the info, including a call to action, check out the NO CLEAN FEED website here
I first heard about this tool at Tech-Ed back in October. The Exchange Server Remote Connectivity Analyzer (ExRCA) tool is a neat online tool which allows Exchange Administrators to test and validate various aspects of their Exchange , including for example, Exchange 2003 RCP over HTTP.
The tool currently provides the following tests:

Exchange 2007 enables much better memory utilization than Exchange 2003 due to its 64-bit architecture. Because of the virtual address space limitations of a 32-bit platform, Exchange 2003 is limited to using 4 GB or less of physical memory.
The memory configuration process for the Mailbox role is more involved than the other roles since the optimal memory configuration depends upon the mailbox count, client profile and number of storage groups.
The recommended configuration for the Mailbox role is based predominantly on mailbox count and user profile.The rule of thumb sizing for the Mailbox server role requires an understanding of the average client user profile. This profile can be collected using the Microsoft Exchange Server Profile Analyzer (EPA).
User Type | Send/Receive per day |
Light | 5 sent/20 received |
Average | 10 sent/40 received |
Heavy | 20 sent/80 received |
Very Heavy | 30 sent/120 received |
The maximum number of Storage Groups configurable in Exchange 2007 has been increased to 50 in the Enterprise Edition (up from 4 with Exchange 2003) and 5 in Standard Edition (up from 1 with Exchange 2003). This increase provides much greater flexibility in server/storage architecture, but the increase has a significant effect on the memory utilization of the Exchange 2007 Mailbox server so Storage Group count is now a factor in minimum memory configuration for Mailbox and Multi-Role servers. In Exchange 2007 Service Pack 1 (SP1), several performance enhancements were made to the Extensible Storage Engine (ESE) that reduce the memory requirements for the Mailbox server role. The following table identifies the specific minimum memory requirements per server, based on the number of storage groups on the server for Exchange 2007 and Exchange 2007 SP1.
Storage Group Count | Minimum Required Physical Memory |
1-4 | 2 GB |
5-8 | 4 GB |
9-12 | 5 GB |
13-16 | 6 GB |
17-20 | 7 GB |
21-24 | 8 GB |
25-28 | 9 GB |
29-32 | 10 GB |
33-36 | 11 GB |
37-40 | 12 GB |
41-44 | 13 GB |
45-48 | 14 GB |
49-50 | 15 GB |
Based on the above information, the following table can be used to assist in estimating the memory requirements of a given mailbox server with a given number of hosted mailboxes with a given profile type:
User Type | Recommended memory |
Light | SG Minimum + 2 MB per mailbox |
Average | SG Minimum + 3.5 MB per mailbox |
Heavy | SG Minimum + 5 MB per mailbox |
