  4. Exchange Server 2007 • X64 bit enhancements • Scalability (memory) • Reduction in disk I/O • Active Directory sites routing • ‘Traditional’ clustering with shared storage • Database replication – LCR, CCR and SCR

  5. Exchange Server 2010 • New replication technology called ‘database availability’ • Public Folders are still here! • New move-mailbox • Remote Management • MAPI on the CAS Server (MoMT) • Windows Server 2008 and R2 only • Real cool Outlook Live!

  6. Exchange Server Roles • Exchange has 5 separate server roles: • Mailbox Server Role • Hub Transport Server Role • Client Access Server Role • Unified Messaging Server Role • Edge Transport Server Role • Roles can be on dedicated hardware or combined, except for Edge Transport

  7. Mailbox Server Role • Contains Mailboxes and Public Folders • MAPI Clients do not connect to MBX • MAPI Clients do connect to PF • Extensible Storage Engine (ESE) • High Availability via replication

  8. Database changes • Drastic changes in the database schema • Less tables, less indexes  better performance • Database page size from 8KB to 32KB • Host large mailboxes (>1 GB) • Database and log files on one SATA disk • SIS is gone…

  9. Database changes cont’d • Storage Groups are gone • Database, log files and checkpoint • Database no longer on server level but on organization level

  10. High Availability • Database Availability • Basically CCR and SCR combined • LCR, CCR, SCR and SCC are gone • No need to install fail-over clustering • Database Availability Group • Multiple Database Copies • “self healing” database functionality • Add servers on demand

  11. DEMO Mailbox Server ROle

  12. Move Mailbox • New Move-Mailbox functionality • Old and New mailbox are synchronized and switched when needed • Small downtime (don’t know about Outlook 2010 though) • Exchange 2007 and Exchange 2010 only

  13. Hub Transport Server Role • Routes all messages in Exchange org • Internal Messages • External messages • Compliancy • Enhanced Disclaimers • Shadow redundancy • Integration with RMS

  14. Client Access Server Role • All clients connect to CAS Server • Including MAPI (=Outlook) clients • New Outlook Web Access (now called Outlook Live) • Cross Browser experience is cool!

  16. MAPI on the Middle Tier • Outlook (MAPI) clients connect to the Client Access Server for mailboxes • No direct connections to the Mailbox Database • Public Folder access still to Mailbox Server

  17. Edge Transport Server Role • Additional layer of security • Message hygiene • Routes all messages to/from Internet

  18. Exchange Management • Management Console & Management Shell • Powershell v2 • Windows Remote Management (WinRM) • ‘known issues’ in Beta1! • Use local shell as work-around

  19. DEMO Exchange management

  20. Coexistence • Exchange 2010 can coexist with: • Exchange Server 2003 SP2 • Exchange Server 2007 SP2 • No support for Exchange Server 2000 • Intra-org: transition • Inter-org: migration

  21. Conclusion • It’s too early to make any conclusion • Exchange 2010 looks promising • Database Availability is key feature • Less complexity (esp. on clusters) • Database changes, less disk I/O • Start looking, start playing, but please don’t bring it into production yet!
