Scalability Enhancements
Unified CM 8.6(1)
General Scalability
increase:
• Up to 10,000 users
per server pair *
• 33% Increase
CTI Scalability
Increase:
• CTI for EVERY user
on the cluster.
• Up to 10,000 CTI
Enabled Users per
server pair *
• 100% increase
* Cluster performance depends on a number of factors. Please use the Cisco Unified Communications Sizing Tool (CUCST) to
determine the number of endpoints/users.

CTI support for Multiple Lines
Unified CM 8.6(x)
 400% improvement from 7.0(1)
 CTI now supports 5 CTI-enabled lines (unique DN or
shared DNs) per device without requiring additional
resources
Previously 1 CTI resource was required per line
 Device BHCA must not exceed 6
 If total device BHCA exceeds 6 or if the device is
configured with more than 5 CTI-enabled DNs, then
additional CTI resources are required.
 Use the Cisco Unified Communications Sizing Tool
(CUCST) to determine the CTI resources required:

CTI support for Multiple Applications
Unified CM 8.6(x)
 400% improvement from 7.0(1)
 CTI now supports 5 CTI applications per device without
requiring additional resources
Previously 1 CTI resource was required per application
 Device BHCA must not exceed 6
 If total device BHCA exceeds 6 or if more than 5 CTI
applications are connecting to the same device, then
additional CTI resources are required.

Definition of terms
Subscriber - a Unified CM server running the CallManager and/or CTI
Manager service
CTI enabled Device - a Cisco IP Phone or Virtual device (CTI port,
RoutePoint) associated to and used with a CTI application
A list of CTI supported devices can be found:
http://developer.cisco.com/web/jtapi/wikidocs
CTI-enabled line - a device DN (unique or shared) enabled for CTI
CTI Provider – a single IP connection between the CTI application and
the CTI Manager service running on a Subscriber
Non-CTI enabled Device – a Cisco IP Phone not enabled, associated
to, or used with a CTI application

Performance Note
 CTI application initialization time for 10,000 lines
(5,000 devices with 2 lines each) is ~3min
50,000 lines (10,000 devices with 5 lines each) is ~19min
 Less lines per device results in faster initialization time
 When using redundant CTI application servers, ensure
both primary and backup applications initialize
concurrently, so failover performance is minimized
 Unified CM 8.6(2) initialization for 50k lines will
complete in ~4min (TESTING IN PROGRESS)
Results will be posted on the CDN J/TAPI Blogs

Determining CTI Resources Required
Unified CM 8.6(1)
Step 1: Determine
Total CTI Device Count
Step 2: Determine Line
Factor
Step 3: Determine Application
Factor
Number of CTI controlled
devices
1-5 lines/device = 1
6 lines/device = 1.2
7 lines/device = 1.4
8 lines/device = 1.6
9 lines/device = 1.8
10 lines/device = 2
1-5 apps/device = 1
6 apps/device = 1.2
7 apps/device = 1.4
8 apps/device = 1.6
9 apps/device = 1.8
10 apps/device = 2
Step 4: Total # of CTI Devices * Max (Line Factor, Application Factor) = Total CTI
Resources needed
Examples:
500 CTI
devices
9 lines per device = 1.8
4 apps/device = 1.0
500 * Max (1.8, 1.0)
500 * 1.8 = 900 CTI resources required
2.000 CTI
devices
5 lines per device = 1.0
9 apps/device = 1.8
2,000 * Max (1.0, 1.8)
2,000 * 1.8 = 3,600 CTI resources required
5,000 CTI
devices
3 lines per device = 1.0
3 apps/device = 1.0
5,000 * Max(1.0, 1.0)
5,000 * 1.0 = 5,000 CTI resources required
10,000 CTI
devices
5 lines per device = 1.0
5 apps/device = 1.0
10,000 * Max(1.0, 1.0)
10,000 * 1 = 10,000 CTI resources required

Cisco Unified Communications Sizing Tool
(CUCST)
 Use the Cisco Unified Communications Sizing Tool
(CUCST) to determine CTI cluster sizing for:
Mixtures of CTI and non-CTI devices
Various Busy Hour Call Attempt Rates
Cases when devices are configured with > 5 lines
Cases when devices are configured with > 5 applications
 Cisco Unified Communications Sizing Tool (CUCST)
will be updated with new rules based on these
scalability rules by June 7, 2011
 For CTI sizing questions email: [email protected]
