Overview This document provides information on a 750-mailbox, Microsoft Exchange Server 2013 (Exchange) storage solution tested on HP MSA 2040 Storage and virtualized with Microsoft Hyper-V on HP ProLiant DL380p Gen8 servers according to criteria specified by Microsoft s Exchange Solution Reviewed Program (ESRP) Storage program. For any questions or comments regarding the contents of this document, see the For more information section. The ESRP Storage program is a Microsoft Exchange Server program designed to facilitate third -party storage testing and solution publishing for Exchange Server. For more details on the program, see: technet.microsoft.com/en-us/exchange/ff182054.aspx Tested with: ESRP Storage Version 4.0 Test date: November 2013 Disclaimer HP produced this document independently of Microsoft Corporation. Microsoft Corporation expressly disclaims responsibility for, and makes no warranty, express or implied, with respect to the accuracy of the contents of this document. Features of the tested solution This solution is for small and midsize businesses that are planning to deploy and virtualize Exchange on HP ProLiant DL380p Gen8 Servers and HP MSA 2040 Storage. The solution allows the use of the Exchange mailbox resiliency database availability group (DAG) feature with the high-availability features of the HP MSA 2040 Storage; providing hardware efficiency and high availability for Exchange users. The solution design is a virtualized Exchange environment supporting 750 mailboxes in a resiliency configuration across two sites (primary site and disaster recovery site). The solution uses a single DAG to support 750 mailboxes, each with a 5 GB mailbox capacity and a work profile of 200 messages sent and received for each user, each day, with additional performance and capacity overhead included. To provide mailbox resiliency, there are four copies of each database; two copies located at the primary site and two copies located at the disaster recovery site. The DAG contains four mailbox servers (two at the primary site and two at the disaster recovery site), with each mailbox server configured as a virtual machine. Each virtual machine resides on its own hypervisor, using the virtualization features of Microsoft Hyper-V. The solution eliminates a single point of failure situation and handles the loss of a storage array, hypervisor server, mailbox server virtual machine, database volume, host bus adaptor (HBA), or switch. For example, during a mailbox server failure or maintenance operation, each mailbox server can handle the compute and storage requirements of all 750 mailboxes. The primary site hosts all 750 mailboxes during normal operations. The performance results outlined in this document are from the testing of a single building block, with a single server failed at the disaster recovery site. See the section Test results summary for more information.

HP has developed the HP Sizer for Microsoft Exchange to assist customers with proper server and storage sizing and configuration for their Exchange deployments. The algorithms developed and implemented in this tool are based on HP s extensive knowledge of both Exchange and the hardware required to run it: CPU, memory, and storage subsystems. This tool is free to download and use, and is designed to allow very quick what if modeling of various configuration and design choices. For more information, visit hp.com/solutions/microsoft/exchange2013/sizer. In addition to the HP Sizer, HP recommends that customers use Microsoft s Exchange 2013 Server Role Requirements Calculator. For more information, visit gallery.technet.microsoft.com/office/exchange-2013-server-role-f8a61780. Storage configuration The recommended best practice for site and server resiliency is two HP ProLiant DL380p Gen8 servers and one HP MSA 2040 Array, with eight 2TB 6G SAS 7.2K LFF (3.5-inch) Dual Port MDL hard drives at each site. For storage performance and redundancy, connect the HP ProLiant DL380p Gen8 servers using two HP StoreFabric SN1000E HBAs in each server to both controllers on the HP MSA 2040. Each HP MSA 2040 uses eight hard drives for the Exchange databases and transaction logs. For additional redundancy against hard drive failures, additional hard drives may be added to the storage and designated as global spares, further protecting against disk failures. The Exchange restore volumes are located on the servers. Figure 4 illustrates the hardware used in this solution at the primary site. Figure 4.

Hyper-Threading is known to improve CPU throughput for most applications. However, the benefits to Exchange 2013 do not outweigh the negative impacts. It turns out that there can be a significant impact to memory usage on Exchange servers when Hyper-Threading is enabled, due to the way the.net server garbage collector allocates heaps. Multipathing Install Microsoft s Multipath (MPIO). Multipathing allows for redundant physical paths to the storage and load balancing of the.

Jetstress 2013 Before installing Exchange Server 2013, test your storage solution with Jetstress to ensure it is configured properly and meets your requirements. For more information on Jetstress, see: microsoft.com/en-us/download/details.aspx?id=36849. RAID Level RAID 1 is the selected RAID configuration for this solution with a stripe size of 256 KB (256 KB or larger is recommended). Provisioning of other RAID types is supported but not recommended for this Exchange Server solution. Mailbox Copies In addition to the features of RAID 1 protection, additional fault tolerance was achieved with four copies of the mailbox databases. Hypervisor Snapshots Some hypervisors include features for taking snapshots of virtual machines. Virtual machine snapshots capture the state of a virtual machine while it is running. This feature enables you to take multiple snapshots of a virtual machine and then revert the virtual machine to any of the previous states by applying a snapshot to the virtual machine. However, virtual machine snapshots are not application aware; using them can have unintended and unexpected consequences for a server application that maintains state data, such as Exchange. As a result, making virtual machine snapshots of an Exchange guest virtual machine is not supported. Oversubscription Many hardware virtualization products allow you to specify the number of virtual processors that should be allocated to each guest virtual machine. The virtual processors located in the guest virtual machine share a fixed number of logical processors in the physical system. Exchange supports a virtual processor-to-logical processor ratio no greater than 2:1, although we recommend a ratio of 1:1. For example, a dual processor system using quad core processors contains a total of 8 logical processors in the host system. On a system with this configuration, do not allocate more than 16 virtual processors to all guest virtual machines combined. Follow Hypervisor Vendor Guidance Always consult the Hypervisor vendor for best practices and recommendations when virtualizing Exchange deployments. For specific information on Exchange 2013 Virtualization, visit: technet.microsoft.com/en-us/library/jj619301(v=exchg.150).aspx Windows Volumes Ensure that the Windows volumes are formatted with the 64KB allocation unit size for best performance. For more information on Exchange 2013 Storage Configuration Options and Best Practice recommendations, see: technet.microsoft.com/en-us/library/ee832792.aspx Test results summary This section provides a high-level summary of the test data from ESRP and a reference to the detailed HTML reports, generated by the ESRP testing framework. For solutions that use a uniform building block style, in which each building block is independent and isolated, ESRP requires testing only one building block. For this solution, a building block consisted of one HP ProLiant DL380p Gen8 server and one
HP MSA 2040 array, with eight (8) 2TB 6G SAS 7.2K LFF (3.5-inch) Dual Port MDL drives hosting all 750 mailboxes. However, for actual deployments of this solution, additional hardware is required at both the primary and disaster recovery sites. For a complete solution, contact your HP Reseller or HP Sales Representative. Reliability Reliability testing exercises the storage with the maximum sustainable Exchange load for 24 hours. The goal is to verify that the storage can handle the maximum load for an extended amount of time. Both log and database files are analyzed for integrity after the stress test to confirm that no database or log corruption occurred. After running the 24-hour test, we found no relevant errors reported in the event log for the storage reliability testing, and no errors reported for the checksum process. Storage performance results Storage performance testing exercises the storage with the maximum sustainable Exchange load for two hours. The test measures storage response times under the maximum sustainable Exchange load. The following data is the sum of all logical disk s and an average of all logical disk latency in the two-hour test duration. This solution is designed around an Exchange deployment with a single DAG. The DAG has two mailbox servers in the primary site and two mailbox servers in the disaster recovery site. Ideally, the two servers in the disaster recovery site should host all active mailboxes when the primary site is offline (planned or unplanned). The storage performance results table below shows the worst-case scenario when one server is hosting all 750 mailboxes. Needed disk transfers/sec 120 disk transfers/sec 726 disk reads/sec 499 disk writes/sec 226 database disk read latency (ms) 18.6 database disk write latency (ms) 1.4 Transaction Log Log disk writes/sec 176 log disk write latency (ms) <1 backup / recovery performance This section contains two test reports. The first report measures the sequential read rate of the database files; the second report measures the recovery/replay performance (playing transaction logs into the database). The tests measure the read rates and log replay rates with all mailboxes under concurrent or simultaneous load. Read-Only Performance This test measures the maximum backup rate for Volume Shadow Copy Service (VSS) aware backup applications. The following table shows the average and sum of the database reads. MB read/sec per database 158 MB read/sec total 632 Transaction Log Recovery / Replay Performance This test measures the maximum rate that log files can play against the databases. The following table shows the average rate for log files played. Each log file is 1 MB in size. 13
number of log files played 503 time to play one log file (sec) 2.2 Conclusion The information discussed in this solution brief highlights the tested performance results and configuration best practices for an Exchange solution supporting 750 5GB mailboxes and a 0.16 IOPS workload for each user (200 messages sent and received per user, per day with additional performance and capacity overhead included). The tested solution included an HP MSA 2040 array with eight (8) 2TB 6G SAS 7.2K LFF (3.5-inch) Dual Port MDL drives for the mailbox database storage and transaction logs. Testing demonstrated the storage subsystem provides sufficient IOPS for 750 Exchange users, with each user having a workload up to 0.97 IOPS. The test results and data presented in this document are from the ESRP test framework. Test results are only a guide; customers should test their specific solution to make sure it meets their requirements. The ESRP program is not a benchmarking program. The tests do not measure the maximum throughput for a given solution.
