E2K3 Environment – Key Points
Microsoft TechNet Seminar 2006 E2K3 Environment – Key Points Platform based on Exchange 2003 and Windows 2003 Relatively complex routing topology based on Exchange 2003 Routing Group configuration Back-End Servers in A\A\A\P cluster configuration (Standalone servers in Birmingham) Multiple Message Bridgehead & FE servers deployed Synchronous SAN Replication between Manchester & Bristol DR Data Centre No site resilience for Manchester, Birmingham or London Tape infrastructure in every datacentre Seminar Name
9
Contoso Business Drivers
Microsoft TechNet Seminar 2006 Contoso Business Drivers Reduce the cost of operating the messaging platform Standardise levels of availability and resilience to site and component failure across Contoso Reduce operational overhead by standardising technology across the platform where possible Meet recently introduced Service Level Agreements Functional requirements of the service should be functionally equivalent to the current platform Create a consistent platform on which to progress the adoption of ancillary services such as Mobile device access & 3rd party archive solutions Seminar Name

Microsoft TechNet Seminar 2006
Mailbox– Key Points CCR within each datacentre – MNS 2 node clusters SCR targets in DR datacentres Reliance on expensive storage solutions eliminated – deploy DAS and reduce costs DAS means that more of the infrastructure is brought into the messaging support teams Backup via DPM which reduces the reliance on a large tape infrastructure Seminar Name

Microsoft TechNet Seminar 2006
Routing – Key Points Routing now based upon AD site topology and therefore less complex to manage Use SubmissionServerOverrideList to control routing in Manchester & Glasgow datacentres (members of the same AD site) Seminar Name

15
Remote Users – Key Points
Microsoft TechNet Seminar 2006 Remote Users – Key Points Bringing mailboxes into central datacentres enables service to meet agreed SLA’s Birmingham users brought into central datacentre providing latency and bandwidth requirements can be met Reduction in costs of providing infrastructure in Birmingham Seminar Name

Client Access London LAN Manchester 25,000 Users Call Centre Glasgow LAN HT 1GB London 6,000 Users Head Office 100MB Glasgow 25,000 Users Manufacturing HT ADSite2 Manchester LAN Manchester Data Centre ADSite1 Seminar Name
17
Client Access – Key Points
Microsoft TechNet Seminar 2006 Client Access – Key Points If Contoso want a unified namespace for OWA then CAS servers in Manchester will proxy requests to London Otherwise use separate namespaces in Manchester and London Seminar Name
18
Microsoft TechNet Seminar 2006
Backup Solution Current Backup Solution Using traditional streaming backups – nightly full backups Proposed Backup Solution VSS backups – nightly changes plus 15 minute incremental transaction log syncs Plus tapes for longer term archival Seminar Name
19
Windows 2008 Operating System benefits
Microsoft TechNet Seminar 2006 Windows 2008 Operating System benefits Faster log Shipping Support for multi-subnet failover cluster Improvements for Client Access Servers (CAS) Reduced downtime for hardware maintenance Near-Zero downtime for NTFS corruption Easier deployment Support for IPv6 Seminar Name
20
Hardware Virtualisation
Microsoft TechNet Seminar 2006 Hardware Virtualisation Generally not recommended for any Exchange role Verify support stance for your chosen solution Ensure that virtualisation does not introduce additional layers of complexity in management and recoverability Seminar Name

Microsoft TechNet Seminar 2006
Summary Reduction in the cost of operating the messaging platform Cheaper Storage – DAS plus on storage replication No infrastructure in Birmingham Support costs reduced as less complex to operate Less reliance on expensive tape infrastructure Standardise levels of availability and resilience to site and component failure across Contoso CCR plus SCR is strategy for mailbox role resilience N+1 for CAS and Hub Transport role servers The same infrastructure across Contoso Reduce operational overhead by standardising technology across the platform where possible Seminar Name
23
Microsoft TechNet Seminar 2006
Summary Continued Functional requirements are that the service should be functionally equivalent to the current platform Create a consistent platform on which to progress the adoption of ancillary services such as Mobile device access & 3rd party archive solutions Reduce operational overhead by standardising technology across the platform where possible Messaging platform have more control over a standard platform – DAS, DPM, CCR\SCR across Contoso Meet recently improved Service Level Agreements SLA’s concerning resumption of service given component & datacentre failures can now be met MNS clusters, CCR, SCR, N+1 Seminar Name
