  3. Stating the obvious? Microsoft statement: The hardware that you select for your Exchange deployment has the greatest effect on performance. * So now, let’s examine Dell’s perspective * http://www.microsoft.com/technet/prodtechnol/exchange/guides/E2k3Perf_ScalGuide/d97992e6-8292-4150-a25f-4a78f2533958.mspx

  4. Server sizing • Processors • Memory • Storage • Tools • High availability

  5. Processors • 32 or 64 bit ? • Exchange 2003 is a 32bit application. • Will NOT install on 64bit Windows Server 2003. • So for now: • Run Exchange on a 32bit OS on 64bit processors for future proofing. • Future proofing? • Exchange 12 will ONLY be available as a 64bit application. • Testing has shown almost 75% reduction in IOs per second. • This could result in almost a 4x increase in number of user on the same disks.

  6. Processors • Dual Core • Microsoft Exchange runs up to 18 % faster ! • No extra software cost !

  7. Processors • Hyper-threading • Turn it on! • 15 – 25% gain • How many processors? • Dictated by the load. • Due to memory restrictions sweet spot for Exchange 2003 is 4 Processors.

  8. Memory • 32bit limitations mean Exchange can access a maximum of 4GB Ram. • Memory switches allow you to play with the amount available to Exchange. • This option is best used in environments where Exchange is the only application running on the server.

  9. Storage We have discussed processor and memory requirements However, Disk subsystem bottlenecks cause more performance problems than server-side CPU or RAM deficiencies.

  10. Storage • Performance is all down to IOPS and Spindles !! • Understanding your User Profile according to Microsoft.

  11. Storage Formula • Number of disks required = (IOPS/mailbox × number of mailboxes) ÷ (IOPS/disk × RAID penalty factor) • Example:Imagine the following scenario: • We need to calculate the storage for a new Exchange infrastructure which will serve 1000 users with average profile (0.4 IOPS/user, 50MB mailbox size). • Let’s assume that 15K RPM disks will be used with a RAID 0+1 configuration. So, in order to determine the number of disks: • (number of disks) = (IOPS/mailbox × number of mailboxes) ÷ (IOPS/disk × RAID penalty factor) = (0.4 × 1000) ÷ (180 × 0.80) = 2.78 • Since we are using RAID 0+1, we must round up to the nearest even number, which is 4. Got that?

  12. Dell Exchange Sizing Tool Don’t panic!!!

  13. The Microsoft Exchange Server 2003 SP2 Solution from Dell Dell’s Exchange Advisor Tool is an easy way to visualise the Exchange architecture you want to deploy, including hardware, software and services.

  14. The Microsoft Exchange Server 2003 SP2 Solution from Dell Dell’s Exchange Advisor Tool is an easy way to visualise the Exchange architecture you want to deploy, including hardware, software and services.

  15. Key things to remember • Invest in high performance disks and spindles • It is better to have smaller capacity disks that utilise each spindle's performance than to use fewer spindles with large capacity. Fast storage with a sufficient amount of spindles is one of the most important investments you can make in your messaging infrastructure. • Consider performance before capacity • Relying on capacity as the primary metric for storage sizing often results in poor performance for your disk subsystem. For example, most administrators who select a RAID-5 solution do so to maximize storage usage. However, in many cases, properly sizing the performance of your spindles requires you to use more physical disks for RAID-5 than RAID-0+1.

  16. Other Tools • Several tools for measuring performance are included with Exchange Server 2003, including Exchange Server Stress and Performance (ESP) 2003, Jetstress, and Load Simulator 2003 (LoadSim). • Microsoft Windows Server™ 2003 also includes some general performance tools including Network Monitor and System Monitor. • In addition to these tools, analyze your current user loads to establish a minimum server requirements baseline. Understanding how your users use the system is one of your biggest challenges. • After you determine your hardware requirements, you should conduct a pilot test to make sure performance levels are acceptable.

  17. Mitigate risk with Dell’s Enterprise Solution Centre State-of-the-art technology centre • Customers evaluate and test Dell’s Enterprise IT solutions • Located in Limerick, Ireland • Extensive Technology Resources • Skilled Consultants to help customers design the best solutions Focus Areas • Proof of concept • Customer specific workshops • Business Solution testing Customer benefits • Reduce risk of deployment • Protect against failure • Optimise Resources

  18. Dell’s Enterprise Solution Centre helps you overcome the following challenges… Reduce the risk of deployment • Load Test the Solution • Determine Sizing Characteristics • Scalability of Solution • Iron out bugs Protect against Failure • Protect against downtime • Failure Simulations • System • Data • Application • Site • Test Recovery Procedures Optimise Resource • Tune for Performance • System • Network • Application • Manage Infrastructure • Will a new IT project have the capacity to meet future requirements? • How will it perform if our requirements grow faster than we expect? • What will make it crash and how do we recover if it does? • How do I protect my business from natural or catastrophic disasters? • Is the hardware and software tuned or optimised to perform better for my needs? • How can we maximize the return on our investment in technology?

  19. Enterprise Solution Centre (ESC) – what customers think… Over 95% of customers surveyed, would recommend Dell as an Enterprise Solution Partner after using the ESC ESC Supported customer projects to the value of $197M in FY06 "The testing was extremely useful as it provided us with realistic benchmarks, tools and techniques which we will be able to apply in future projects." "Learned about Clustering, saw Altiris and MOM. Learned a few things about our own applications that it's not possible for us to test back in the office." "Before visiting the Solution Centre, we had very little experience of the Clariion technologies especially MirrorView...Using the lab we now have a better idea on how this form of replication will work. Having the latency generator to simulate distance was a big plus." "That we now know what is possible and not possible with our current DR strategy" "It showed the importance of using Proof of Concept before implementing Hardware designs"

  20.
