Case Study: HA mail, file and print
•
Small office solution
–
Small scale consolidation with increased throughput and
improved fault tolerance
>
Past: 4 dedicated servers for mail, file, print and an Internet gateway
>
Today: 2 state-of-the-art servers running mail, file, print and Internet gateway
in dedicated and thus isolated VMs, DMZ realized with firewall VM, all VMs
instrumented with Heartbeat v2 to fail-over services on standby virtual
machines.
>
More reliability, fault tolerance and thus high level of availability for business
critical IT services. Improved performance by using latest, but still cost
effective hardware, flexibility to do 'rolling' upgrade if performance
requirements increase over time (services stay online)
