Hosted Exchange Platform Architecture
The following diagram shows a high-level architecture for the
Cobweb Hosted Exchange service platform:
The service platform is based upon
Microsoft’s Hosted Messaging and Collaboration (HMC 4.0) prescribed
architecture and is designed to support hundreds of thousands of
mailboxes.
The platform contains no single point of failure and consists of
clustered Microsoft Windows Server 2003 and Microsoft Exchange
Server 2007 software. The service is hosted on HP ProLiant
servers accessing data from a resilient EMC Fibre Array Storage
Area Network, with centralized disk and tape backup.
This model offers the following advantages:
- 24/7 proactive server and application management with
sophisticated monitoring tools, including Systems Centre Operations
Manager 2007 and HP Systems Insight Manager.
- Capacity management processes and systems ensure robust,
reliable and consistent service performance
- Service delivered from a Tier 1 ISO27001 accredited data
centre, which included multiple internet feeds with automatic BGP
redundancy, uninterruptible power supplies, fire suppression
systems and 24/7 manned security
The architecture is optimized for performance, non-disruptive
maintenance and service reliability, providing the highest
availability and maximum data security.
