Abstract: Compaq achieved record-breaking Exchange Server

scalability by achieving 15,000 MMB on a ProLiant 7000 server

equipped with four 400-MHz Intel Pentium



II Xeon



processors.

Using Microsoft’s Load Simulation utility, the ProLiant 7000 with

four 400-MHz processors was tested at Compaq’s Microsoft

Competency Center in Redmond, Washington. The favorable results

of this testing demonstrate the superior performance capabilities of

four-processor servers based on the Intel Pentium



II Xeon



processor as compared to eight-processor servers based on the Intel

Pentium



Pro available from competitors.

Compaq and Microsoft have worked to optimize Microsoft Exchange

Server performance on Compaq server products to provide an

optimal balance between performance, availability, manageability,

and cost. Compaq not only provides world-class server platforms,

but also the experience necessary for the successful deployment of

messaging and collaborative applications

Compaq ProLiant 7000

The Compaq ProLiant 7000 is the ultimate standards-based server delivering the most scalable

performance and the highest levels of availability. The ProLiant 7000 supports up to four

PentiumII Xeonprocessors and 8 GB of system memory. Its architecture supports Enhanced

PCI Hot-Plug and a Triple-Peer PCI bus design (five 64-bit PCI, four 32-bit PCI, and one ISA

slot). Standard with the ProLiant 7000 is the 64-bit PCI SMART 3100ES Array Controller that

supports 3 Wide Ultra SCSI-3 channels and 64 MB of cache. Leveraging Fibre Channel, the

Compaq ProLiant 7000 can support nearly 7 TB of external storage. Combined with the latest

high-availability features and processor technology, the ProLiant 7000 is designed for the most

demanding and mission-critical applications.

Exchange Server Performance Test Results

The tests were conducted using Microsoft MAPI Messaging Benchmark (MMB). The MAPI

Messaging Benchmark (MMB) measures throughput in terms of a specific profile of user actions,

executed over an 8 hour working day. This benchmark utilizes the ‘Medium User’ setting of the

Load Simulator MAPI tool. Results should be interpreted as a benchmark for messaging

throughput and should not be confused with deployment recommendations. Factors such as

backup/restore, topology and other issues should be considered when planning a deployment.

What the Benchmarks Don’t Tell You

It is important to understand that benchmarks such as these are designed to give Exchange Server

implementation planners baseline references for understanding the capabilities of hardware

platforms from a single vendor such as Compaq or other competing hardware vendors. When

interpreting these benchmarks, two things should be kept in mind.

First, consider whether benchmarks are performed on what can be referred to as customer-

deployable configurations. A hardware vendor may publish a result that is based on a platform or

configuration that should not be deployed in a real-world Exchange Server deployment. For

example, many vendors (including Compaq) publish results using disk subsystems configured

with RAID0. While RAID0 does provide the highest levels of disk subsystem performance, it

fails to provide any protection against data loss. Compaq recommends deploying an Exchange

Server with disk fault tolerance such as RAID1 or RAID5 for the highest levels of data

protection.

Second, most vendors, including Compaq, conduct benchmarks for Exchange Server that are

single-server in nature. Also, keep in mind that benchmarks do not account for issues such as

backup and disaster recovery or information store maintenance sizing. Whatever the issue, care

must be taken when interpreting benchmarks to ensure that they represent useful information for

your Exchange Server deployment and are based on valid simulation methodologies.

While it is significant that the ProLiant 7000 server can successfully scale to 15,000 medium

MAPI e-mail users (MMB) in a single-server benchmark exercise, Compaq recommends careful

evaluation of all issues involved in real-world Exchange Server deployments – issues such as

management, administration, and disaster recovery.

MAPI Messaging Benchmark (MMB) - LoadSim Medium

User Redefined

To distinguish clearly between throughput benchmarks and capacity planning information for

Microsoft Exchange Server, Microsoft has established the MAPI Messaging Benchmark (MMB)

based on the workload from LoadSim Medium User profile. The MAPI Messaging Benchmark

representative workload focuses on the resulting throughput and clearly communicates the profile

under test.

The workload profile has not changed from the former LoadSim Medium User, but expressed in

clearer fashion. The intent is to make sure that customers can understand the MAPI Messaging

Benchmark workload and can compare it to other platforms. In addition, the renaming of the

benchmark reinforces that the test is a measurement of messaging throughput and that additional

considerations are required in capacity planning.

MMB Transaction Load

The transaction load created by the benchmark is equivalent to the user actions over an eight-hour

day as shown in Table 3.

cleared from the deleted items folder during the test as this is assumed to happen when the user

logs off.

Load Simulator

The main tool used in generating the workload the MMB benchmark was Microsoft Load

Simulator. Load Simulator is a tool for simulating a client user load on an Exchange Server. Its

purpose is to enable a single Windows NT machine called a LoadSim client to simulate multiple

Microsoft Exchange client users.

The operation of Load Simulator users is governed by a Load Simulator profile. This profile

controls factors such as how long a Load Simulator "day" is, how many e-mail messages to send

in a day’s time, how many times to open and read e-mail, whether to use distribution lists,

whether to use public folders, etc.

Load Simulator creates a highly accurate simulation of reality. It mimics the full Microsoft

Exchange Client in many respects. First, it uses .MSG files, the same format used by the

Exchange Client. This guarantees that messages generated by Load Simulator have the same

properties as those sent by real users of the Exchange Client. Second, Load Simulator uses the

same MAPI remote procedure call (RPC) semantics as those used by the Client. Third, Load

Simulator registers MAPI change notifications in the same manner as they are registered by the

Client. Finally, Load Simulator even emulates the Microsoft Exchange Client list box cache,

which the Client uses for folder and message panes in the viewer when a user browses and selects

messages on the server. For more information on LoadSim Medium canonical profiles, refer to

the LoadSim documentation at http://www.microsoft.com/exchange/library/loadsim55x86.exe.
