3 Network Messaging/Collaboration Client (MAPI, POP3, IMAP, SMTP, NNTP, HTTP) Client MAPI POP3 NNTP HTTP IMAP Protocols Messaging/Collaboration Engine Server Disk Transacted or File-based Store

4 Performance and Scalability How can I size and scale my servers? How do do performance management? Migration/Interoperability Migration from Legacy Messaging Systems Interoperability with other Messaging Systems Administration/Maintenance Server Administration/Operating System Integration Directory Integration (X.500, LDAP, Other) Store Maintenance (Consistency Checking, Defragmentation, Virus Scanning) Disaster Recovery/High Availability Increasing Store Sizes Limits of Current Backup Technology Cost/Benefits of Clustering Business and Collaborative Applications What Applications are a fit? How do you handle on-going maintenance and support?

5 THE LEADING EXCHANGE DEPLOYMENT PLATFORM Typical server brand used to deploy Microsoft Exchange (multiple answers allowed) % of Organizatio Source: Creative Networks, 1997! "#

10 "%&' Migration from PC or mainframe based mail and calendaring to Exchange Exchange Architecture and Topology Complexities What are the requirements to support user population? Should I buy 200 small servers or 20 BIG ugly servers? What user loads can my Server support? What are the Trade-offs? How do I tune my messaging environment? How do I engage in Capacity Planning for Exchange Server? What Performance can I expect?

22 ()2 User work patterns, tasks, transactions Increasing numbers of users Metric: Response Time, Throughput, Transactions/sec Consider average versus peak loads Have you saturated the clients? Server? Network? Emulates client behavior (tasks, transactions) Collects response time/throughput information Allow custom workloads to be configured Proper workload characterization is the key to success TOOLS: LoadSim (MAPI) InetLoad (POP3, IMAP, NNTP, SMTP) BlueCurve Dynameasure Messaging/Pro (MAPI) NetFusion ProSim (NTSim) (MAPI)

27 Response Time Server s reaction to load Only part of the Picture Throughput Messages/sec Transactions/sec Response time Number of users What is a Bottleneck High Demand Resource Workload Dependent The Darn things move Delivery rate Incoming message rate

28 Processor Subsystem Consider Faster CPUs or Multiple CPUs Consider Larger L2 Cache (SMP Scalability) Use Hardware RAID to reduce CPU overhead Memory Subsystem Consider adding memory (up to 256MB for 5.0) Even more with Exchange 5.5 (3GB) /3GB Switch for NT Enterprise Disk Subsystem Consider more disks, striping (RAID), Multiple Controllers Add memory to decrease disk demand (IS Buffers) Analyze Disk I/O (I/O Profiling)* Separate Sequential Logs from Random (IS) I/O Faster Disk I/O = Faster Response Times Network Subsystem Generally not an issue with Exchange Server Consider use high speed network cards or switching to isolate traffic

29 How to Analyze Disk I/O (Formulas) RAID0: READS + WRITES = I/Os per second RAID1: READS + (2*WRITES) = I/Os per second RAID5: READS + (4*WRITES) = I/Os per second Disk Subsystem Capabilities: 4 & 9GB Drives: Random: I/Os/sec Sequential: I/Os/sec PerfMon Counters (LogicalDisk) EXAMPLE: (12) 4GB drives in a RAID5 Array for IS Store (Random I/O) PerfMon: READS: 265; WRITES: 168 Array Capability: 12*70 = 840 I/Os per second Exchange Server Demand: 265+(4*168) = 937 I/Os/sec DISKBOUND!
