Abstract: The Compaq ProLiant 3000 offers the best performance

and leading price/performance of any Intel-based or RISC-based

dual processor systems. To demonstrate Exchange Server 5.5

scalability on the Compaq ProLiant 3000 server, tests of user loads

from 1000 to 6500 simultaneous MAPI e-mail users were conducted

at Compaq’s Microsoft Competency Center located in Redmond,

Washington.

Microsoft Exchange Server has been the focal point for extensive

development and testing by both Microsoft and Compaq. Throughout

this activity, 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. This performance brief

provides a basis for the number of users that can be supported when

deploying Microsoft Exchange Server on the ProLiant 3000 server.

Performance Results

The tests were conducted using Microsoft’s Load Simulator tool. For each test, the Load

Simulator Medium MAPI canonical profile was chosen. The Medium MAPI profile reflects the

task workload of a typical corporate e-mail user - including daily common mail tasks such as

send, browse, read, forward as well as adding calendar entries for tasks and distribution list usage.

The Response Time score represents a 95th percentile score of the measured test run. The score is

What the Benchmarks Do Not Reveal

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 one would

never use in a real world Exchange Server deployment. For example, many vendors have

published results using disk subsystems configured with RAID0 disk arrays. While RAID0 does

provide the highest levels of disk subsystem performance, it fails to provide any protection

against data loss. One must consider the implications of the same benchmark performed on a

system using RAID5. This would provide the necessary fault tolerance that typical deployments

require but has different performance implications. In addition, most vendors, including Compaq,

conduct benchmarks for Exchange Server that are single-server in nature. Benchmarks also do

not account for issues such as backup and disaster recovery as well as information store

maintenance sizing concerns. Whatever the issue, care must be taken when interpreting

benchmarks from any vendor to ensure that results represent useful information to your Exchange

Server deployment and are based on valid simulation methodologies

Load Simulator

The main tool used in generating the workload used in this scalability demonstration was the

Microsoft Exchange Server Load Simulation utility called Load Simulator. As its name implies,

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 existing e-mail, whether to use distribution lists

and public folders.

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

 

ECG096/0998

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.

Several steps are necessary to performing a successful simulation. The Load Simulator setup and

initialization process comes first. Load Simulator creates the test topology by first generating the

user directory entries. Next, the test store is initialized and populated with the test messages and

folder items. The tests are typically run for up to 8 hours depending upon the user load simulated

and amount of time required to reach a steady-state for measurement purposes. During a test run,

users logon to the Exchange Server and begin processing various messaging tasks. Task response

time data is logged to the LSPERF.LOG file and client messages and error logging is stored in the

LOADSIM.OUT file. To produce test score the LSLOG utility is used to parse out the

LSPERF.LOG file and calculate the response time score. By default, 95th and 50th percentile

response time scores are calculated. 95th percentile response time scores for the MAPI/RPC

protocol should be less than 1000 milliseconds (ms), according to Microsoft. Also, the Exchange

Server IS Send Queue and the MTA Work Queue (other message and delivery queues should also

be considered depending on the protocol) must consistently return to near-zero during the steady-

state period for which test measurements are taken. Queues that continue to grow and fail to

return to near zero indicate that the server is not sustaining the required workload. There should

be no errors logged by the LoadSim clients during the test. When these conditions are met, a

successful test run has been completed. For more information on LoadSim Medium canonical

profiles, please refer to the Load Simulator documentation at:

(http://www.microsoft.com/exchange/library/loadsim55x86.exe).

Balancing Scalability and Availability

While server performance and capacity are key criteria in selecting a messaging deployment

platform, one must also consider price/performance. Several competing hardware vendors offer

platforms capable of supporting heavy user loads. They also provide these systems at

significantly higher cost. Compaq delivers leading performance on industry-standard platforms

with the lowest total cost of ownership.

For many corporations, messaging and collaboration have quickly become mission critical.

Unscheduled downtime for any server can result in a significant loss of productivity. To limit

exposure to downtime, Exchange Server 5.5 and Compaq ProLiant Clusters provide high

availability through Microsoft Cluster Server (MSCS). When MSCS is deployed on Compaq

ProLiant Clusters, enterprise-messaging customers can achieve scalability without sacrificing the

reliability that is required in an enterprise environment.

Another critical concern is backup and disaster recovery. Compaq provides industry leading tape

array and library hardware solutions partnered with applications like Computer Associates’

Cheyenne ArcServe. These solutions will help meet the requirements of enterprise customers

deploying messaging and collaboration applications.
