Features This document describes the testing of a 12,000 mailbox resiliency (2-copy) database availability group (DAG) configuration for Exchange Server 2010
with a NetApp FAS3140 storage system. The FAS3140 is a member of NetApp’s industry-leading FAS3100 midrange product family. Leveraging NetApp’s Unified Storage Architecture and inherent storage efficiency
features, the FAS3140 is a highly available system that can handle diverse needs – SAN and NAS, primary and secondary storage. Compared to the
previous generation FAS3040 midrange controller, the FAS3140 provides mid-sized and large enterprises with a significant performance increase, higher I/O scalability, and a 25% increase in storage capacity The FAS3140
comes in a 6U form factor with dual independent hot swappable controllers and dual hot swappable power supplies. Storage options include external SAS
shelves with either SAS or SATA disks and FC shelves with either FC or SATA disks for a total maximum disk count of 420 drives.
The FAS3140 system is simple to deploy and manage. It ships with a wealth of integrated data protection and management software based on Data
ONTAP® to help increase storage utilization and the efficiency of your system
and storage administrators, such as:
4
• Thin provisioning helps avoid the costly over provisioning and time-
consuming reconfiguration that is typical with other storage solutions. • Deduplication enables you to store only one copy of each unique data
object, substantially reducing capacity requirements.
For the purposes of this tested Exchange deployment, various NetApp best practice recommendations for an Exchange deployment were followed. The
FAS3140 being tested used standard NetApp features such as Snapshot™, RAID-DP®, FlexVol® flexible volumes, and SnapDrive®.
The tested deployment includes disk space allocated for backing up and
restoring Exchange databases and logs using NetApp Snapshot technology. Snapshot technology provides in-place, logical backups of an entire Exchange
environment, usually in seconds, regardless of whether the data being backed up is several megabytes or hundreds of terabytes. Additionally, NetApp Snapshot technology causes virtually no loss of performance
following Snapshot creation and use going forward. The performance results listed in this report were produced with two NetApp Snapshot copies in place
on the tested storage systems. RAID-DP is a high performance implementation of RAID 6 that provides
double parity across the disk subsystem and protects against the failure of up to two disks per RAID group. Calculations have shown double parity RAID
offers over 160 times the protection against data loss than RAID 10 and almost 4000 times the protection against data loss than RAID 5. The performance results listed in this report were produced with RAID-DP
enabled.
FlexVol volumes enable the creation of logical storage volumes across a large pool of disk drives known as an aggregate. FlexVol volumes provide three core advantages for workloads such as Microsoft Exchange:
1. Using FlexVol volumes, the capacity and performance bandwidth of a
large collection of fast drives can be made available to all volumes. Even very small FlexVol volumes have the performance benefit of a very large number of drives.
2. A large number of volumes may be created, all with independent Snapshot copy schedules, mirroring events, etc.
3. All FlexVol volumes can be managed independently, while receiving the maximum I/O benefit of a much larger pool of drives
SnapDrive for Windows offers a rich set of capabilities that virtualizes and enhances storage management for Microsoft Windows environments.
SnapDrive is tightly integrated with NTFS to provide a layer of abstraction between application data and physical storage associated with that data.
5
For this ESRP testing environment, NetApp SnapManager® for Microsoft Exchange (SME) was not required. SnapManager for Exchange is an
Exchange software backup and recovery management solution that integrates NetApp Snapshot backups with Microsoft Exchange Server via the
Microsoft standard and approved Volume Shadow Copy Services (VSS) snapshot interface. NetApp highly recommends SnapManager for Exchange as a part of a production Exchange deployment.
For this ESRP testing environment, two DAGs (each containing 2 mailbox
servers) were used. The detailed DAG architecture is specified in the next section.
Solution Description This section outlines the Exchange 2010 mailbox resiliency solution NetApp
implemented to run the ESRP tests. Storage:
� A pair of FAS3140 storage controllers
o A Flash Cache Module (256GB) per controller
� Data ONTAP® 7.3.2
� SATA disk shelves, 1 TB 7.2K RPM drives
� Link to FAS3140 Windows Server Catalog listing: http://www.windowsservercatalog.com/item.aspx?idItem=b79e68ad-68ef-2f36-d338-8403c10f398d&bCatID=1511
Switches:
� A pair of Brocade 4100 4Gbps FC switch
Figure 1 depicts the DAG architecture and the topology of the Exchange 2010
mailbox resiliency solution using the NetApp FAS3140 storage system. The FAS3140 consists of two storage controllers: fas3140-9 and fas3140-10. The
first Exchange data copy (active copy) is on fas3140-9. The second Exchange data copy (passive copy) is on fas3140-10.

Figure 1) Topology and DAG architecture of the FAS3140 mailbox resiliency ESRP testing.
Only the primary copy storage is described below. The secondary copy storage (shown gray in Figure 1) is configured identically (from the host on down to the spindle including brand, model, firmware, drivers, etc.).
The fas3140-9 storage controller was configured with four aggregates for
Exchange 2010 databases and log files. Four FlexVol flexible volumes were created on each aggregate, three for databases and one for log files, for a total of sixteen flexible volumes. Sixteen LUNs were then created (one LUN
per flexible volume). Among them, twelve LUNs for database and four LUNs for log files. The details about the placement of aggregates, volumes, and
LUNs are enumerated in the table following.
7
For Mailbox Resiliency configuration, databases and log files can be placed on the same set of disk drives (see http://technet.microsoft.com/en-
us/library/ee832792.aspx). Therefore, the log files for DB11, DB12 and DB13 are located on LOG1; the log files for DB14, DB15 and DB16 are located on
LOG2; and so on. Controller

The DAG configuration is as follows:
� Four mailbox servers: 3650-1, 3650-2, 3650-3 and 3650-4
� 1000 mailboxes per database
� Twelve active databases total:
o DB11 to DB16 hosted by 3650-1
o DB21 to DB26 hosted by 3650-3
� Twelve passive databases total (shown in gray in Figure 1): hosted by
3650-2 and 3650-4. All passive databases are on separate aggregates
and on the separate but identical storage controller: fas3140-10
� Using NetApp RAID-DP
� Two copies of databases
The ESRP-Storage program focuses on storage solution testing to address performance and reliability issues with storage design. However, storage is not the only factor to take into consideration when designing a scale up
Exchange solution. Other factors which affect the server scalability are: server processor utilization, server physical and virtual memory limitations,
8
resource requirements for other applications, directory and network service latencies, network infrastructure limitations, replication and recovery
requirements, and client usage profiles. All these factors are beyond the scope for ESRP-Storage. Therefore, the number of mailboxes hosted per
server as part of the tested configuration may not necessarily be viable for some customer deployments.

bottlenecks in an Exchange system, please refer to Microsoft's Troubleshooting Microsoft Exchange Server Performance, available at
http://go.microsoft.com/fwlink/?LinkId=23454.

Best Practices Exchange server is a disk-sensitive application. Based on the testing run using the ESRP framework, we would recommend the following to improve
the storage performance.
11
For Exchange 2010 best practices on storage design, please visit http://technet.microsoft.com/en-us/library/dd346703.aspx
Sizing Performance, stability, disaster recovery procedures, and general Exchange maintenance all benefit from proper Exchange sizing. NetApp has studied the
I/O patterns of Exchange systems running on NetApp storage. When a customer approaches NetApp for an Exchange storage solution, NetApp
leverages this knowledge and expertise to properly size the storage specifically to the customer’s environment. Several factors are taken into consideration in this process including but not limited to:
� Number of mailboxes
� Mailbox size � IOPS per mailbox � Storage platform type
� Physical drive type � Backup retention time
Layout
Another key consideration for Exchange Server 2010 is layout of databases, volumes, and LUNs. NetApp storage solutions can take full advantage of the performance benefits of aggregates and flexible volumes. And following
proper layout guidelines is essential to ensuring a high performing, low latency Exchange solution. Consulting with your NetApp Exchange specialist
about proper layout will ensure that your Exchange deployment on NetApp storage will perform optimally in your environment.
Mailbox Resiliency
For this ESRP submission, we followed these NetApp Exchange best practices:
• Use dedicated FlexVol volumes for databases. • Use dedicated FlexVol volumes for transaction logs. • Use SnapDrive to provision LUNs. This reduces the complexity of LUN
provisioning and additionally means that diskpart is not required or recommended as SnapDrive provides for correct LUN sector alignment.
• Spindle counts for databases and log files are derived from consulting with NetApp Exchange specialists. Further information on Exchange sizing is available from your local NetApp Exchange specialist.

Backup strategy
The deployed solution allocates sufficient disk space for backing up and
restoring Exchange databases and logs using Microsoft VSS technology and NetApp Snapshot technology.

Test Result Summary This section provides a high level summary of the test data from ESRP and the link to the detailed html reports which are generated by the ESRP testing
framework. Please click on the underlined headings below to view the html report for each test.
Reliability
A number of tests in the framework are to check Reliability where the tests run for 24 hours. The goal is to verify the storage can handle high IO load for
a long period of time. Both log and database files will be analyzed for integrity after the stress test to ensure no database/log corruption.
The following list provides an overview: (click on the underlined word will show the html report after the reliability tests run)
• There were no errors reported in any of the event logs collected for the reliability tests.
• There were no errors reported during the database and log checksum process.
Storage Performance Results
The Primary Storage performance testing is designed to exercise the storage with maximum sustainable Exchange type of IO for 2 hours. The test is to
show how long it takes for the storage to respond to an IO under load. The data below is the sum of all of the logical disk I/O’s and average of all the
13
logical disks I/O latency in the 2 hours test duration. Each server is listed separately and the aggregate numbers across all servers is listed as well.

Database Backup/Recovery Performance
There are two test reports in this section. The first one is to measure the
sequential read rate of the database files, and the second is to measure the recovery/replay performance (playing transaction logs in to the database).
Database Read-only Performance
The test is to measure the maximum rate at which databases could be backed up via VSS. The following table shows the average rate for a single
database file.
Host 3650-1
MB read/sec per database 36.78
MB read/sec total per server 220.65
Host 3650-3
MB read/sec per database 36.65
MB read/sec total per server 219.88
Transaction Log Recovery/Replay Performance
The test is to measure the maximum rate at which the log files can be played
against the databases. The following table shows the average rate for 500 log files played in a single storage group. Each log file is 1 MB in size.
Host 3650-1
Average time to play one Log file (sec) 0.953
Host 3650-3
Average time to play one Log file (sec) 0.946
Conclusion This document demonstrates that the NetApp FAS3140 with a Flash Cache
Module is a high-performance, highly-reliable and high-efficiency storage system more than capable of supporting 12,000 Exchange 2010 users at
0.120 IOPs per user and 2000 MB mailbox size in Exchange mailbox resilience configuration. Moreover, extra storage space was allocated in this tested solution for backing up and restoring Exchange databases and logs
using Microsoft VSS technology and NetApp Snapshot technology.
This document is developed by NetApp, and reviewed by the Microsoft Exchange Product team. The test results/data presented in this document is
based on the tests introduced in the ESRP test framework. Customers should not quote the data directly for his/her pre-deployment verification. It is still
15
necessary to go through the exercises to validate the storage design for a specific customer environment.
The ESRP program is not designed to be a benchmarking program; tests are
not designed to get the maximum throughput for a giving solution. Rather, it is focused on producing recommendations from vendors for Exchange application. So the data presented in this document should not be used for
direct comparisons among the solutions.
NetApp offers its customers complete sizing information for Exchange Server deployments through its systems engineers. Contact your local NetApp sales office for additional information.
