ESG Labs have recently completed their performance and scalability report on Exchange Server 2013 running on Windows Server 2012
Summary of the testing is:
ESG Lab performed hands-on testing of a virtualized tier-1 Exchange 2013 application workload. The workload used was designed to emulate thousands of Exchange users performing typical activities including sending and receiving e-mails, making calendar entries, updating contacts, and managing to-do lists. The storage activity of up to 48,000 typical Exchange users was tested using a single physical server hosting up to twelve Windows Server 2012 Hyper-V virtual machines.
Key findings included:
ESG Lab confirmed that the improved IOPS performance efficiency of Exchange 2013 and the manageably low IOPS overhead of Microsoft Server 2012 with Hyper-V can be used to consolidate tier-1 e-mail application workloads with confidence. A single server hosting a virtualized Exchange infrastructure deployed within twelve Hyper-V virtual machines supported the I/O requirements of up to 48,000 simulated Exchange users with excellent response times.
This is great validation of Windows Server 2012 Hyper-v.
