Virtualize Enterprise Applications–ESG Performance Reporting

I seem to be getting a lot of requests for these reports lately so I thought I’d document the URL to find these for reference on this blog.

Most recently, the addition of Exchange 2013 performance on Hyper-V was just posted:

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:

· Windows Server 2012 with Hyper-V supported the needs of 48,000 emulated Exchange mailboxes.

· Performance scaled linearly from two to 12 virtual machines on a single server, as sustained IOPS reached a maximum of 5,894—over 60% more than the targeted IOPS rate of 3,600.

· Response times remained manageably low reaching a maximum of 15.31 milliseconds. This was well under the Microsoft maximum threshold guideline of 20 milliseconds for Exchange database reads.

· The I/O efficiency improvements in Exchange 2013 reduce the cost of delivering e-mail support in mixed virtual server environments. ESG Lab supported up to 48,000 mailboxes on 12 virtualized Exchange servers on a single Dell M620 blade server.

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.
