What is Changed in Exchange Server 2010?

As always, as new features come, old features go. There are inevitably a few that have
found themselves on the "deprecated list" this time around, and so will not be continued in
Exchange Server 2010 and beyond. Since this is a much shorter list than the "new features",
Here they are:
• There are some major changes in Exchange Server clustering: in Exchange Server 2007
you had LCR (Local Continuous Replication), CCR (Cluster Continuous Replication) and
SCR (Standby Continuous Replication) – three diff erent versions of replication, all with
their own management interfaces. All three are no longer available in Exchange Server
• Windows Server Fail-over Clustering has been removed in Exchange Server 2010.
Although seriously improved in Windows Server 2008, a lot of Exchange Administrators
still found the fail-over clustering complex and diffi cult to manage. As a result, it was still
prone to error and a potential source of all kinds of problems.
• Storage Groups are no longer available in Exchange Server 2010. The concepts of a database,
log fi les and a checkpoint fi le are still there, but now it is just called a database. It's
like CCR in Exchange Server 2007, where you could only have one database per Storage
• Owing to major reengineering in the Exchange Server 2010 databases, the Single
Instance Storage (SIS) is no longer available. This means that when you send a 1 MB
message to 100 recipients, the database will potentially grow by 100 MB. This will surely
have an impact on the storage requirements in terms of space, but the performance
improvements on the Database are really great. I'll get back on that later in this chapter.
