13. Mailbox Role Sizing Rules Of Thumb 2-socket platform best for performance and TCO User profile determines resource requirements for IOPS, memory, CPU Don’t forget about high availability (Database Availability Groups)! Storage I/O and capacity requirements Memory Database cache requirements (reduces I/O) CPU Required for RPC operations, content indexing, mailbox assistants, replication operations Network Log replication and RPC operations consume bandwidth

18. Client Access Server Role Sizing Rules Of Thumb 2-socket platform best for performance and TCO CPU is typically the bottleneck, memory sizing is key as well 3 CAS CPU cores for every 4 Mailbox CPU cores (servicing active users) Load balancing is important for performance and high availability 2GB RAM per CPU core is optimal CPU Required for handling client workload transactions, content conversion, garbage collection Memory Memory required for ongoing transaction processing Network All clients connect to CAS, network bandwidth and latency are important for client experience, load balancing likely required Storage Utilized for content conversion, logging

19. Outlook0.350.37 Outlook Anywhere 0.800.44 Exchange ActiveSync (delta from Outlook) 1.601.04 Exchange Web Services (Microsoft Entourage) 0.710.54 Outlook Web Access 0.860.88 IMAP4*0.860.14 POP3*0.330.79 * IMAP4 & POP3 protocols do not support sending new mail, so the observed costs do not reflect any sent messages within the user profile. Reference CAS server platform has 2 processor sockets on the motherboard populated with Intel Xeon L5335 4-core processors running at 2.00GHz for a total of 8 physical cores. Hyperthreading is disabled on this platform to allow for more accurate computation of CPU costs. The platform runs with 16GB of RAM. Observed costs will vary depending on user profile and other parameters defining a workload – these values are only meant to represent observed costs for a normalized sample workload.

20. Transport Roles Sizing Rules Of Thumb 2-socket platform best for performance and TCO CPU is typically the bottleneck, memory sizing is key as well 1 Transport CPU core for every 7 Mailbox CPU cores (no A/V) or 1 Transport CPU core for every 5 Mailbox CPU cores (with A/V) 1GB RAM per CPU core is optimal CPU CPU required for message processing, hygiene activities, custom agents Memory Database cache requirements (reduces I/O), messages in queue represented in memory for perf Storage Low to moderate I/O requirement for relay & delivery activity, queuing needs more I/O+capacity Network Bandwidth utilized to relay/deliver messages – scales with message volume, latency can cause queuing

21. Unified Messaging Role Sizing Rules Of Thumb 2-socket platform best for performance and TCO 2GB RAM per core is optimal CPU is typically the bottleneck, particularly when Voice Mail Preview is being used Default 100 concurrent calls per server (inbound or outbound) Voice Mail Preview is CPU intensive: ~1 message/min/core CPU CPU used for media operations and Voice Mail Preview transcription – UM is typically “CPU heavy” Network Network bandwidth used for calls as well as communication with Mailbox role. Minimize latency for best user experience Memory Memory required for ongoing transaction processing Storage UM doesn’t have significant storage requirements

22. Multi-Role Hub/CAS Servers Sizing Rules Of Thumb 2-socket platform best for performance and TCO CPU is typically the bottleneck, memory sizing is key as well 1 Hub/CAS CPU core for every 1 Mailbox CPU core 2GB RAM per CPU core is optimal 8 core root CAS/HUBMailbox 16 core root CAS/HUBMailboxCAS/HUBMailbox 24 core root CAS/HUBMailboxCAS/HUBMailboxCAS/HUBMailbox

23. Multi-Role “Brick” Servers Sizing Rules Of Thumb Recommend maximum 4-socket platform for multi-role deployment Use 8GB RAM plus 3-30MB per mailbox (see Mailbox role sizing details)

24. Virtualized Server Roles Sizing Rules Of Thumb Size for physical resources, add ~12% CPU overhead for hypervisor Avoid resource oversubscription Don’t co-locate Mailbox databases on a root server CAS+Hub combination can make scale calculations easy
