The Company
A large UK supplier of cut flowers with around 450 Exchange users in the UK.
The Challenge
The existing Exchange 2003 servers in the UK were located at three individual sites with no fault tolerance to the hardware or software.
The Solution
- EACS designed a solution based on Exchange Server 2010 to centralise services, simplify administration and increase resilience of e-mail services.
- The solution uses Database Availability Groups to replicate mailbox databases between servers located in 2 separate sites, providing the ability to "fail-over" a database or an entire server in the event of scheduled or unplanned downtime.
- External clients connect to mail services via a Client Access Array, comprised of 2 servers in a hosted data centre, to maintain connectivity should a server suffer network or power outage.
- Additional Client Access servers are located at the primary sites to provide internal client access to e-mail services and further fault tolerance in the event of a failure of the servers in the hosted data centre or another site.
- This was achieved while still maintaining co-existence with the legacy Exchange 2003 servers located in production sites abroad.
