VMware has set a record in system capacity and resource utilization for running Microsoft Exchange. VMware deployed Microsoft Exchange Server 2007 on VMware Infrastructure 3 (VI3) and supported 16,000 heavy-user Exchange mailboxes on a single 16-way multi-core IBM System x3850 M2 server. Running Microsoft Exchange on VMware software increased by more than 100% the number of supportable Exchange users as compared to Microsoft Exchange’s prescribed recommendations for running natively in a non-virtualized environment. VMware virtualization software enables enterprises to take advantage of multi-core hardware servers to run demanding enterprise applications more efficiently.

VMware software allows enterprise applications to overcome scalability limitations associated with non-virtualized environments. Microsoft Exchange Server 2007 is one of the most used messaging applications deployed in production datacenters worldwide. Historically, however, the design of operating systems and applications has imposed limits on the number of recommended CPUs and memory per physical server. As a result, under-utilized physical servers have proliferated in today’s datacenters, which are costly to manage, maintain, power, and cool.

By running VMware software on powerful multi-core servers, customers can consolidate larger workloads on fewer physical servers – while at the same time actually improve capacity. As a result, customers reduce the capital expenses of hardware maintenance, and the environmental impact of unnecessary power consumption.  Customers can also benefit from VMware management tools, which enable solutions never possible before virtualization, including moving workloads from one physical server to another without interruption, automating resource scheduling, and ensuring high availability.

VMware benefits are not just being demonstrated in labs, they’re being realized by organizations in production environments using a variety of server platforms. For example, Adrian Jane, Infrastructure & Operations Manager at The University of Plymouth, who is responsible for running approximately 50,000 Microsoft Exchange mailboxes across four virtual machines running VMware Infrastructure 3, said, “Our entire Microsoft Exchange deployment is virtualized on VMware Infrastructure 3, and we are extremely pleased with the performance we’ve seen. Furthermore, VMware also provides us with a high availability solution that has advantages over traditional clustering options. When it comes to managing production applications, VMware is a strategy, not just a product.”

At the inaugural VMworld Europe user conference here in Cannes, VMware President and CEO Diane Greene said to a keynote audience of over 4,500, “Today’s results published on our website support what our customers have been telling us from day one – Microsoft applications run best on VMware. Multi-core hardware advancements complement VMware virtualization software, and vice versa.  Customers are able to ‘refresh’ their datacenters with more powerful hardware, and they can continue to reduce their space, power and manageability requirements.”
