Overview
Introduction This Proven Solution Guide summarizes observations of best practices that were discovered, validated, or otherwise encountered while validating the functionality of Microsoft Exchange 2007 enabled by EMC® CLARiiON® CX4-120, EMC Replication Manager, and Hyper-V on Microsoft Windows Server 2008 using the Microsoft iSCSI Software Initiator. EMC Replication Manager uses Microsoft Volume Shadow Copy Service (VSS) to perform online replication of Exchange Server 2007 storage groups. EMC's commitment to consistently maintain and improve quality is led by the Total Customer Experience (TCE) program, which is driven by Six Sigma methodologies. As a result, EMC has built Customer Integration Labs in its Global Solutions Centers to reflect real-world deployments in which TCE use cases are developed and executed. These use cases provide EMC with an insight into the challenges currently facing its customers. This document provides the specifications for the customer environment (that is, the storage configurations, design, sizing, and backup considerations) that constitute the requirements for this use case. This document outlines the detailed components that make up the environment and their relationship to each other. The use case test scenarios are listed, together with the objectives for completing them and the expected results.

Chapter 1: About This Document
Business challenge
Overview The business challenge is to provide customers with the ability to use Microsoft
Exchange Server 2007 SP1, with local data replication, to allow for fast data recovery in the event of database loss or corruption. The storage architecture for this solution is based on a design that utilizes a “building block” approach, which repeatedly builds upon itself as customers’ requirements grow and additional space and fault tolerance are required. This solution uses a building block designed for 600 users. The challenge was to ensure that, at the smallest building block level, all components worked as expected and within Microsoft Exchange database latencies at all times, while running local data replication.
Technology solution
Overview A consolidated Microsoft Exchange infrastructure can be the first step towards
meeting the challenges of managing e-mail. This solution demonstrates the testing completed in a Microsoft Exchange environment. The solution described in this reference architecture utilizes EMC’s CLARiiON CX4-120 using the Microsoft iSCSI Software Initiator, which is a simple, easy-to-manage storage system.
Objectives
Overview The following are the objectives of this solution.

Chapter 2: Storage Design Layout
Overview
Introduction The purpose of this use case is to build a Microsoft Exchange 2007 SP1 with Hyper-
V on Windows Server 2008 environment on the CLARiiON CX4-120 platform and integrate it with Replication Manager 5.2.1. This use case is not intended to be a comprehensive guide to every aspect of an Exchange 2007 SP1 with Hyper-V on Windows Server 2008 solution. The storage design layout presented in this chapter applies to the specific components used during the development of this solution. The scope is roughly bound by the following parameters and assumptions. This is a representative of Replication Manager 5.2.1 integration with Microsoft Exchange 2007 SP1 and Hyper-V on Windows Server 2008 implementation using the Microsoft iSCSI Software Initiator. Note, however, that actual implementations will vary from the parameters shown, based on testing results.

Chapter 2: Storage Design Layout
Storage design layout
Introduction The following sections detail the layout principles associated with this solution.
Goals The following describes some of the key objectives when designing a configuration
for the CLARiiON CX4-120 storage layout: • The performance requirements must accommodate the required I/O based on the
user profile. • The design should be easy to understand and build upon (using a building block
approach). • The design should help to minimize the time and complexity of designing the
storage layout.
Determining building block requirements
A building block approach was used to determine the number of physical spindles required for this solution. This was a commercial-level building block approach, based on the Microsoft Exchange Solution Reviewed Program (ESRP) testing and submissions, which are a proven solution for the desired IOPS per building block. For more information, see ESRP Storage Program - EMC CLARiiON CX3-20c (600 User) iSCSI Storage Solution for Microsoft Exchange Server 2007. For more information on Microsoft’s ESRP program, visit: http://technet.microsoft.com/en-us/exchange/bb412164.aspx For more information about EMC solutions using the ESRP framework, visit: http://www.emc.com/esrp
RAID group layout
RAID group layout design
This design was tested based on previous, known performances of the building block configurations using metaLUNs. This storage solution was based with a single DAE solution in mind, having the ability, once this configuration was proven, to show that linear results would be possible as building blocks are added.

Chapter 2: Storage Design Layout
RAID group diagram
The RAID group layout is illustrated in the following diagram.
Best practices and recommendations
CLARiiON RAID group configuration
For CLARiiON RAID group configuration, it is recommended to: • Keep the Exchange database and log LUNs in separate RAID groups. • Keep the Replication Manager clone LUNs in a separate RAID group from the
Exchange production LUNs. • Balance the RAID group across the storage processors. • Ensure that a hot spare disk is assigned.
Exchange online maintenance
For Exchange online maintenance, ensure that Replication Manager jobs are running outside the Exchange online maintenance window. Do not run Exchange online maintenance against an Exchange storage group while its Replication Manager job is running. Note: Failure to follow this recommendation will cause a large decrease in the clone resync speed and slow online maintenance. A best practice for running Replication Manager jobs is to run them during off-peak hours.
Clone RAID group configuration
For clone RAID group configuration, ensure that a separate RAID group is used for clone LUNs. Note: Failure to do so will result in degraded performance in the production Exchange server and in the time to complete the Replication Manager jobs. Since the clone is used as a protect methodology, using the same drives for the source and destination defeats the purpose.

Chapter 3: Server and Network Design
Server design
Overview of server design
This solution was created with two Active Directory servers, one physical server and one virtual server. A physical server was also used for the System Center Virtual Machine Manager (SCVMM) server. The rationale for using this is that SCVMM will not install in a Hyper-V child OS. The following describes the configuration of each component used.
Configuration of components
Each Hyper-V Server was configured with 64 GB RAM. Guests were separated onto each Hyper-V Server to maximize the usage of these servers.
Hyper-V Server 1 • Microsoft Active Directory server • Exchange 2007 Mailbox role • Exchange Hub/CAS roles
Hyper-V Server 2 • Replication Manager mount host • Replication Manager Server • LoadGen Server 1 • LoadGen Server 2 The Hyper-V child partitions were configured as follows:
Microsoft Exchange Mailbox Server • 4 processors • 16 GB RAM • 3 network cards
Microsoft Active Directory Server • 2 processors • 2 GB RAM • 1 network card
Microsoft Exchange Hub/CAS Server • 2 processors • 8 GB RAM • 1 network card
EMC Replication Manager mount host server • 2 processors • 8 GB RAM • 3 network cards
Microsoft LoadGen Server • 2 processors • 2 GB RAM • 1 network card

17
Chapter 3: Server and Network Design
EMC Replication Manager Server • 4 processors • 2 GB RAM • 1 network card Note: Microsoft Windows Server 2003 is required for EMC’s Replication Manager Server, which is not currently supported to run on Microsoft Windows Server 2008. Once Replication Manager is supported, it will be possible to have the Replication Manager Server and the mount host as part of the same virtual server. For this solution, the mount host had to be separate, as the mount host must run the same operating system as the production Exchange server. The solution in total requires four licenses for Microsoft Windows Server.
Quantity Description
1 Windows Server 2008 Enterprise* (Hyper-V on Windows Server 2008 allows for up to four guests licenses)
2 Microsoft Windows 2008 Standard Edition Physical Domain Controller Microsoft System Center Virtual Machine Manager
1 Microsoft Windows Server 2003 standard edition for the virtual Replication Manager Server.
* Microsoft’s Microsoft Windows Server 2008 Enterprise License allows the use of up to four instances of the server software in virtual environments (for details, visit http://www.microsoft.com/windowsserver2008/en/us/licensing-faq.aspx). When possible, it is recommended to spread the Virtual Hard Disk (VHDs) files across the CLARiiON service processors to prevent performance issues if there is a very active VM. A recommended configuration with the service processors on a CLARiiON array is:
Service Processor A • Microsoft Active Directory Server • Exchange 2007 Mailbox role • Exchange Hub/CAS roles
Service Processor B • EMC Replication Manager mount host • EMC Replication Manager Server • Microsoft LoadGen Server 1 • Microsoft LoadGen Server 2

Chapter 3: Server and Network Design
Network design
Overview of network design
Two physical 1 Gb/s Ethernet network switches were used for this solution: one for production network traffic and the other for iSCSI (through VLAN) traffic to the array. Dedicated virtual networks were created to match the physical network and iSCSI networks. Guests requiring access to iSCSI were given additional network connections for array connectivity.
Best practices for virtual machines
Overview These changes not only free up space but also free up a lot of memory.
Disable hibernation on Windows Server 2008
Hibernation is on by default in Windows Server 2008. This feature consumes additional processor power and storage space and is not needed for Exchange and Active Directory servers, which have built-in features to handle power loss. To disable hibernation on Windows Server 2008:
1. Run the following command from the command line on all virtual machine servers. powercfg -Hibernate OFF
2. Run the following command to confirm that hibernation is off. Dir /ah
3. Reboot the server.
Registry change
Changing the registry specifies whether the user-mode or kernel-mode drivers and kernel–mode system code can be paged to disk when not in use. Disabling this in a guest OS prevents unnecessary caching in the guest and host. A reboot of the system is needed for this change to take effect. To change the registry, add the following registry key to all virtual machines. Note: Do not do this on a physical server. [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management] • DisablePagingExecutive=dword:00000001

Chapter 3: Server and Network Design
Best practices for iSCSI
Best practices The following are some iSCSI best practices for connectivity to EMC CLARiiON
storage arrays using iSCSI connectivity. These recommendations are intended to provide a high performance and stable solution. This section does not include all possible iSCSI best practices. • Always use at least two NIC ports for iSCSI traffic to ensure high availability and
maximum throughput for storage connections. • Use dedicated switches for production and iSCSI networks. If this is not possible,
ensure that VLANs can be created on the switch being used to guarantee that the iSCSI traffic from the server to the array is separated from all other network traffic.
• Ensure that all ports on the switch are set to auto-negotiate 1000. Note: It is not possible to disable auto-negotiation on ports on the Dell Powerconnect 6224 switches. While the GUI/CMD line allows the change, the port will become disabled and non-functional.
• Disable the spanning tree on network switches. • Disable power management on the NICs on the server. • Disable each of the following in advanced settings on the NICs Jumbo packet:
− IPv4 Checksum offload − TCP Checksum Offload (IPv4) − TCP Large send Offload (IPv4) − UDP Checksum Offload (IPv4)
• On the iSCSI NICs on the Exchange servers, clear the checkboxes for Client for Microsoft Networks and File and Printer Sharing for Microsoft Networks.
• Modify the registry with the following changes on the Exchange servers to optimize iSCSI performance: − HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TCPIP\Parame
ters KeepAliveTime=Dword:300000 (Decimal)

Chapter 4: Installation and Configuration
Overview
Introduction This chapter provides the procedures and guidelines for configuring the components
that make up the validated solution scenario. For more information about the background to this solution, see ESRP Storage Program - EMC CLARiiON CX3-20c (600 User) iSCSI Storage Solution for Microsoft Exchange Server 2007. The configuration presented in this chapter applies to the specific revision levels of components used during the development of this solution. Before attempting to implement any real-world solution based on this validated scenario, gather the appropriate installation and configuration documentation for the revision levels of the hardware and software components in the solution. Version-specific release notes are especially important. EMC Replication Manager software is used for the creation of VSS cloned images and snapshots of the Exchange database and log file LUNs. While the software is capable of backup and restore using this technology, this paper focuses on the backup technology and comparative times when running sequential or parallel jobs. With Replication Manager, it is possible to configure clone jobs to run in order, sequentially, where database and log file LUNs are cloned or snapped one at a time or in parallel, where two jobs can run simultaneously. Backing up and check-summing the databases using the eseutil /K command would complete faster.

Navisphere CLI scripts configuration
Background Several options are available when configuring a CLARiiON CX4-120 storage array.
One option is to use the Navisphere user interface; another is to use the CLARiiON Navisphere Secure Command Line Interface (naviseccli). This solution provides details on using the command line interface. This method is recommended as a best practice because it is faster and gives the ability to document the array configuration while creating the array storage. This information can then be used in a disaster recovery document to quickly re-create the exact configuration.
Overview The CLI commands used to create this solution are provided in the Supporting
Information section. The following steps assume that planning has already taken place on how the entire array is configured, including decisions on the RAID group configuration, RAID type, number of LUNs, size of LUNs, and so on. Note: All lines for each section can be copied and pasted into a Windows command window. Copying and pasting lines of scripts automates the use of the commands without requiring additional user input. All CLI commands provided in this document are specific to this configuration. Details such as RAID types, LUN numbers, names, sizes, and volume labels can be modified to suit the implementation. They are provided here as an example of exactly what was completed to configure this specific solution.
Prerequisites The following are the prerequisites for a successful configuration:
• Prior to configuration Navisphere Agent and Navisphere CLI must be installed. • Connectivity and registration must be set up prior to running the following scripts.
The scripts can be run from any server with Navisphere CLI installed. • Hosts should be set up and configured but they are not required for LUN creation.
Hosts are required for host addition to the storage groups but not for the storage groups themselves.
Steps for naviseccli configuration
The following are the steps for naviseccli configuration: • Create storage groups • Create RAID groups • Bind LUNs • Create reserved LUN pool LUNs • Add LUNs to reserved LUN pool • Add hosts to CLARiiON storage groups • Add LUNs to clone private LUNs

Disk management scripts
Overview
Once the LUNs and hosts have been assigned to the storage group, they are available on the server. Rescan the disk drives in the Device Manager and all of the LUNs will appear. Microsoft Windows Server 2008 places new volumes in an offline state by default. Disks must be brought online before partitions can be created. Diskpart can be used to configure each disk completely. Using scripts here simplifies and speeds up the process for configuring the volumes. Planning is required to ensure the scripts are correct.
Make volumes accessible to the host for data
Before the database and log volumes can be configured, the mount points must first be configured. To do this, follow the steps below:
• Type diskpart at the command prompt. The following commands can be selected together and copied and pasted into Diskpart to run automatically without any prompting. Note: This is the configuration for this solution. Disk numbers may differ during implementation. The following is an example of the two script files used with Diskpart to create the S: drive (drive 10 mount point root), and then assign a drive to the mount point directories. The following assumes that drives 10 and 11 are the mount point drives for S: and T: Note: With Windows Server 2008, Diskpart does not require the alignment of a partition to 64. Note: This is only required when using Diskpart. GUI configuration does this automatically. assigning letters for mp root drives -------mountpoint.txt select disk 10 online disk attributes disk clear readonly create partition primary select partition 1 assign letter s: select disk 11 online disk attributes disk clear readonly create partition primary select partition 1 assign letter t: ------- -------mounts.bat

From the Windows command prompt, enter: C:\Diskpart /s mountpoint.txt C:\mounts.bat C:\diskpart /s mountdrives.txt C:\fmtdrives.bat Using these scripts as an example, it is possible to quickly mount, partition, and format all the presented drives. It is recommended to use a file for recording all the actions.

Microsoft Exchange performance
EMC Backup and Recovery for Microsoft Exchange 2007 Enabled by EMC CLARiiON CX4-120,
Measuring good Exchange performance
Good Microsoft Exchange performance can be measured by multiple factors such as overall server utilization, disk latencies, and good response times from Outlook clients (RPC latencies). Some of the performance parameters analyzed during LoadGen testing included: • RPC Averaged Latency
The RPC Averaged Latency performance counter records the average time, in milliseconds (ms), that it takes to process the last 1,024 packets. If the RPC Averaged Latency performance counter data is lower than 50 ms, the server can process the requests in a reasonable amount of time. If the counter is higher than 50 ms for more than several seconds, this indicates that the server is having difficulty keeping up with the load. As a result, users may experience delays when accessing their e-mail messages.
• RPC Operations/Sec
The RPC Operations/Sec performance counter shows the rate at which remote procedure call (RPC) operations occur. The RPC Operations/sec performance counter is a good rate counter to measure the Exchange Server workload because all MAPI-based actions use the RPC protocol.
• RPC Requests
The RPC Requests performance counter records the number of client computer requests that are currently being processed by Microsoft Exchange. This counter has a maximum value of 100. When the Exchange store has 100 RPC operations being processed, it denies any new connections. On a healthy server, the number of outstanding requests should be lower than 50. If the number is more than 50 for a sustained time, this indicates that the RPCs are backed up and waiting to be processed and that the client computers are probably experiencing delays.
• RPC Num. of Slow Packets
The RPC Num. of Slow Packets performance counter should always be less than two. Some normal operations may take longer than two seconds but the average should always be less than two.
• Process/% Processor Time
Process/% Processor Time is the percentage of elapsed time for which all of the process threads used the processor to execution instructions. An instruction is the basic unit of execution in a computer, a thread is the object that executes instructions, and a process is the object created when a program is run. Code executed to handle some hardware interrupts and trap conditions are included in this count.
• Processor/% Processor Time
Processor/% Processor Time is the percentage of elapsed time that the processor uses to execute a non-Idle thread. It is calculated by measuring the percentage of time that the processor spends executing the idle thread and then subtracting that value from 100%. (Each processor has an idle thread that consumes cycles when no other threads are ready to run.) This counter is the primary indicator of processor activity and displays the average percentage of busy time observed during the sample interval.
Replication Manager, and Hyper-V on Windows Server 2008 using iSCSI Proven Solution Guide
26
Chapter 5: Testing and Validation
Note that the accounting calculation of when the processor is idle is performed at an internal sampling interval of the system clock (10 ms). On today’s fast processors, % Processor Time can therefore underestimate the processor utilization as the processor may be spending a lot of time servicing threads between the system clock sampling interval. Workload-based timer applications are one example of applications that are more likely to be measured inaccurately, since the timers are signaled just after the sample is taken.
Performance counters for RPC processing
The performance counters used for RPC processing are listed in the following table.
Counter Expected values
MSExchangeIS\RPC Requests Indicates the number of MAPI RPC requests currently being serviced by the Microsoft Exchange Information Store service. The Microsoft Exchange Information Store service can support up to 500 RPC requests simultaneously before rejecting new client requests.
Should always be lower than 70.
MSExchangeIS\RPC Averaged Latency Indicates the latency in milliseconds, averaged across all RPC operations in the past 1,024 RPC packets.
Should always be less than 25 milliseconds.
MSExchangeIS\RPC Operations/sec Indicates the current number of RPC operations that are submitted to the Information Store each second
This is a good indicator of client activity and is used for information only.
MSExchangeIS\RPC Num. of Slow Packets Indicates the number of RPC packets in the past 1,024 that have latencies that are longer than two seconds.
Should always be less than two. Certain normal operations may take longer than two seconds, but the average should always be less than two.
Performance Monitor data
Clone operations included: • Sequential clone operations • Parallel clone operations
Sequential clone operations In the sequential clone operation, each of the four storage groups that contains a single database is cloned separately, running each job one after the other.
Parallel clone operations In the parallel clone operation, each of the four storage groups that contains a single database is cloned, running two jobs simultaneously. The following chart shows the amount of time to complete each job, along with total times for each of these two types of jobs. As can be seen in this comparison, for the commercial-sized mailboxes completion times are almost identical, coming in at approximately 11 minutes per database individually, or 22 minutes when running two

storage groups, thus 11 minutes per storage group. Completion times are within two minutes of each other, which is an insignificant amount of time over the job run. The start and stop times listed in the chart are based on the 5022 ECCRM Server event logged in the application event log on the RM server.

Comparing PerfMon counters on the Exchange Server
A side-by-side comparison of PerfMon counters on the Exchange Server was done to give a good visual of the different types of job runs and to see more than the reports only. As can be seen in the following diagram, the Process/% Processor Time runs at the same levels and drops almost identically for the different types of scenario, the only difference being in the duration. This depends on how long the customer will endure the processor hit: 11 minutes * 4, or 22 minutes * 2. If the customer wants shorter periods of higher processor and latencies, running sequential jobs may be preferred. If the customer wishes to have smaller periods of time when the processor and latencies are high, the parallel job method may be preferred. Process/% Processor Time at its lowest was almost identical at 245.

Baseline data This run is to show the Exchange baseline while running LoadGen with identical
loads for the two clone method tests. The following diagram shows that the Process/% Processor Time is at the same level as the two cloning tests, without the apparent drops during the cloning of the storage groups.
RPC Averaged Latency
RPC Averaged Latency, when compared in the following charts, shows latencies for the sequential job being slightly higher at 317, except for a brief period at the final portion of the jobs. In the parallel jobs, this same slight spike was lower at 256. Both jobs show a small increase for the first two databases and a slightly higher increase on the second two.

Baseline data for RPC Averaged Latency
Baseline data shows the RPC Averaged Latency running extremely well at a maximum of 27.
Effects of cloning on Hyper-V Servers
During the clone job, there was a slight processor increase on the second Hyper-V Server running the clone jobs, which did not exceed more than 20%.
Baseline data for cloning on Hyper-V Servers
In comparison, in the baseline runs the second Hyper-V Server did not exceed 10%, showing that during the brief clone cycles the Hyper-V Server was negligibly affected by the clone jobs. This translates to the other guests/child partitions not being affected by the virtualized RM Mount host guest.

Log file truncation
The following graph illustrates log file truncation appearing much like the parallel job, with a brief response spike during log file truncation.
Conclusion
In conclusion, it was seen that when comparing the baseline for the two jobs, there is an impact to client and server performance, although only for short durations and for very small amounts of time. Due to this impact, it is recommended to run the clone jobs, either sequentially or in parallel, in the course of maintenance cycles during lower client usage. If a customer needs to run multiple clone jobs throughout the day, then the commercial configuration outlined in this document would be able to successfully complete these jobs with only a slight effect on the user base. Based on the amount of time outlined in this document, the customer could run jobs that would, at most, take approximately one hour to complete. This timeframe would fit into clone cycles during normal meal breaks. Since both methods discussed in this document are completed in the same amount of time, and have almost identical impacts, either method is recommended and can be used without cause for concern.

Test results summary
Summary of results for Hyper-V on Windows 2008 Server testing
Functionality testing was carried out to determine the ability of Replication Manager to run in different modes in comparison to baseline testing. Baseline LoadGen testing was done prior to the cloning process for comparison of data on the impact of cloning on the Exchange Server and CLARiiON CX4 array. Performance testing was completed in this solution using Microsoft’s LoadGen tool to simulate Exchange I/O. Running Replication Manager jobs with LoadGen also running is intended to simulate running clone job during the peak hours of the production day. These tests indicate the worst-case scenario. Baseline testing and testing with Replication Manager running were both completed. As expected, running Replication Manager clone jobs during the production day has an impact both on the array and on Exchange 2007.
Comparison of baseline LoadGen 95th percentile results
The LoadGen comparisons in the following table show that there is a slight increase in latencies during a few tasks but in major tasks like login and logout, these latencies were negligible.

Chapter 6: Conclusion
Overview
Summary This solution contains all components required to run a messaging infrastructure,
which includes protection, at a relatively low cost. The solution benefits customers in terms of: • Protection • Simplified mailbox design
Protection Replication Manager is ideal for backup automation and acceleration in creating a
“Gold Copy” of the production data for an instant restore in the event of corruption. Replication Manager is an easy to use point-and-click application to manage and automate data protection at the array level.
Simplified mailbox design
By using the building block method, Exchange deployments result in predictable performance for all mailbox servers. The building block method removes any assumptions or guesswork when sizing the servers and storage.
Objectives and results
The following table summarizes the objectives and results.
Objective Result
Confirm the functionality of Replication Manager in a virtualized environment using two different methods for running the jobs
Replication Manager jobs were run both sequentially and in parallel. Two “gold” clones were created and the sequential and parallel jobs worked without issue as expected.
Determine if running Replication Manager jobs would have an impact if run during the production day
Results from LoadGen and Navisphere Analyzer confirmed that running Replication Manager jobs during the production day does have an impact on Exchange 2007 performance. Therefore, it is recommended to run the clone jobs during non-production or off-peak hours Differences were also noticed between the two methods used when taking Replication Manager clones. While both jobs completed within the same timeframe, there was an impact on the number of Exchange tasks that were completed during this time.

Chapter 6: Conclusion
Conclusion IT infrastructure management is becoming increasingly complex and so are the
needs for constant information availability and detailed management and reporting capabilities. The growth of data is driving longer backup and recovery windows, and core business processes, such as generating copies of data and establishing recovery processes to meet a business’s service level agreements, are taking longer. With the decreasing cost of disk storage, replication technologies are now more cost-effective for enabling realtime backup and recovery in parallel or sequential environments. With this EMC solution and the advanced features of EMC Replication Manager, the discovery of the environment is automated, allowing customers to easily schedule replications in their backup environment. It places their Microsoft application in the proper state for application-consistent replicas, which accelerates backups and provides instant restore capabilities for their test/development environment or production tiered storage environment. Application images can instantly be transferred between servers or between sites to meet the customer’s business needs. This EMC solution, deployed in a virtual environment based on Microsoft Hyper-V, contributes to improving your operational efficiency, so you can deploy fewer resources for completing the operational tasks of detailed management reporting and deploying replication-based backup processes. Testing verified that using Microsoft Exchange Server 2007 SP1, with local data replication, allows for fast data replication in the event of database loss or corruption. The storage layout for this solution is based on a design that utilizes a building block approach, which repeatedly builds upon itself as the customer’s requirements grow and additional space and fault tolerance are required. Testing confirmed that at the smallest building block level all components worked in a single system, as expected, and within Microsoft Exchange database latencies, while running local data replication.
