Drawer 2 – 35 drives
Side View with one 35 drive drawer extended
3.5” SAS or SATA drives
2 Power supplies
4 for redundancy

Lower cost per drive bay than shelves:
$8500 / 70 = ~$121 / bay vs.
$3400 / 12 = ~$283 / bay

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

Client Access Server Role

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

* 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.
Transport Roles
Sizing Rules Of Thumb
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
•
•
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
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

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)

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
