Exchange 2007 Enterprise

Support all futures as standard edition

• Up to 50 SG
  
• Up to 50 DB ( MS recommends one SG and one DB)
  
• Why it is, recommended this way? Log files for Entire SG, if you have one SG,
  

  If we segregate the logs for one DB which will be better (faster) than writing logs to more than one DB
  

• Consider using different spindles for best performance, even in 64Bit architecture, which is common sense.
  
• SCC (single Cluster Copy)
  
• LCR (Local continuous replication LCR supports 1 Database per Storage Group
  
• CCR (Cluster continuous replication ) CCR only supports 1 Database per Storage Group
