Exchange Server 2007 – Database Architecture changes 


The Exchange database architecture has changed in four significant respects in Exchange Server 2007:



  • The streaming database (.stm) file has been removed from Exchange 2007.
  • Longer log file names are used, thereby enabling each storage group to generate as many as 2 billion log files before log file generation must be reset.
  • Transaction log file size has been reduced from 5 MB to 1 MB to support the new continuous replication features in Exchange 2007.
  • The database page size has increased from 4 KB to 8 KB.
