SBS2008 + Exchange 2007 database sizes

http://blogs.technet.com/haroldwong/...base-size.aspx

Just come across this ??

Is this correct and does this apply to SBS 2008 ? I thought that the maximum
size was 200GB ?

Actually standard Edition (which is what SBS 2008 has), has the hard coded
50 GB limit set out of the box, but you can change it in the reg.
Physically, the limit is 16 TB, but who has a backup solution for something
like that? Ideally, keep the databases small as possible or at a reasonable,
handleable size and use an SQL-based archive solution if it were to be that
large, but practically if the infrastructure were that large, we would
institute multiple and smaller databases for performance reasons, or in
addition, (depending on infrastructure design, link speeds, administration
model, countries' legal limitation guidelines, etc) to multiple Exchange
servers.

Theoretically, the limit is based on your hardware limits. Just keep in
mind, that you will need at least 110% freespace on the drive, whatever you
set it to. So if you had a 16 TB hardware, you will need something like a 35
TB logical drive. Something you will never see with SBS...

as SBS 2008 comes with Exchange 2007 SP1 preinstalled, the following is
true:

"Microsoft Exchange Server 2007 Standard Edition Service Pack 1 (SP1) whose
Information Store database size [has] the default limit of 250 gigabytes"


Background Information:

A database has reached its size limit
[..]
This alert indicates that the Microsoft Exchange Information Store database
has reached the maximum size limit.

This error may be logged in either of the following scenarios:

+ On a computer that is running Microsoft Exchange Server 2007 Standard
Edition whose Information Store database size is approaching the hard-coded
limit of 50 gigabytes and has not had the maximum database size increased by
using the registry.
+ On a computer that is running Microsoft Exchange Server 2007 Standard
Edition Service Pack 1 (SP1) whose Information Store database size is
approaching the default limit of 250 gigabytes and has not had the maximum
database size increased by using the registry.
+ On an Exchange Enterprise Edition server that has had the maximum database
size restricted to the value specified in the error by using the same
registry setting.
[..]
To resolve this alert, locate the key for the Information store in the
registry. A sample registry key is:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\MSExchangeIS\<SERVER
NAME>\Private-013e2e46-2cd7-4a8e-bfec-0e4652b94b00
[..]
+ If the value [Database Size Limit in GB] exists, change the value Database
Size Limit in GB to the desired size in gigabytes.
+ If the value does not exist, add the DWORD value Database Size Limit in GB
and set the value to the desired size expressed in gigabytes.

Note The code for Exchange 2007 sets a hard-coded database size limit of
50 gigabytes for the Standard Edition. The code for Exchange 2007 SP1 sets a
default database size limit of 250 gigabytes for the Standard Edition. This
can be changed by using the process described here. The Information Store
database size for both the Standard and the Enterprise Edition is limited
only by disk space.

I gather from your post, that SBS 2008 comes with Exchange 2007 SP1. I
quoted Exhange 2007 RTM. My apologies for any confusion.
