Caveats


Caveats

Intended for enterprise system sizing initially. Express and SMB solutions are supported in Quote Builder and Solution Expert.

Bill Of Materials needs to be generated with the help of the Dynamic Configurator Tool or the Multi-Line Configurator Tool post sizing.

Sizing of upgrades is not supported.


Migrations & Upgrades

Cisco Unity





TDM & VXML Gateways

Cisco Unified MeetingPlace

Unified CST does not support system or product upgrades, however the tool can assist users with upgrades and migrations in the following manner:

Documentation for the Unified CST will include information on where to find data being requested by the tool in existing systems.

Users will then be able to size the system they are planning to deploy.

Next, based on the sizing output and information about the already owned hardware, the users can determine what additional hardware they need to secure to support the planned deployment.

Updates - Details


Cisco Unified Communications Manager 8.5Call Processing Capacity There has been an overall increase in the Unified Communications Manager (Unified CM) call processing capacity

across all call types. Calls for certain protocols are improved substantially: SCCP to SCCP Calls in detailed tracing mode show an improvement of 15%. In default tracing mode, the improvement

is marginal. SIP to SIP Calls in detailed tracing mode show an improvement of 22%. In default tracing mode, the improvement is

10%. SIP to H.323, SIP to MGCP, SCCP to H.323, SCCP to MGCP all show an improvement of between 15 to 20%.

Constants Server and cluster limits such as those for Phones, Cluster Size, CTI, Locations, Regions, Number of Gateways, etc.,

are unchanged.

Memory Usage Overall memory usage for a typical system deployment is expected to be comparable to the 8.0(3) release. In particular: Memory required for the configuration and registration of a single line unsecure SCCP Phone has increased by 18%,

and for single line secure SCCP phones by 12%. Extra memory required for adding additional lines in SCCP phones has decreased by about 16%.

Memory required for the configuration and registration of a single line for unsecure SIP phones increases by 11%, and for secure SIP phones by 10%. Extra memory required for adding additional lines in SIP phones has increased by about 100%.

Memory required for other configurations and overheads such as that for CTI, Partitions, Calling Search Spaces, Translation Patterns, Route Patterns, etc., are all unchanged.

Memory required for calls placed between two SCCP endpoints is reduced by 18%. Memory required for calls placed between two SIP endpoints remains unchanged. Memory required for calls between SCCP and any other protocol is reduced between 10-15%. Memory required for calls between SIP and any other protocol remains unchanged.

Server Performance

The VM - CUCM_7500 is equivalent in performance to using MCS-7845-I2/MCS-7845-H2 servers. The VM - CUCM_2500 is equivalent to using MCS-7835-I3/MCS-7835-H3 servers. The VM - CUCM_1000 is equivalent to MCS-7825-I5 servers.


Cisco Unified Contact Center Enterprise 8.5Maximum Capacity Increase

Maximum number of local agents supported on high end servers has been increased from 1000 to 1500, provided the deployment uses Unified CVP. Note that the real number of agents that may be supported depends on other traffic and activities in the system.

VM Platform Performance

The SIP call capacity and number of ports supported on the VM-based Unified CVP Call Server has been reduced by about 25%.

New Features

Sizing for two new features in 8.5(1) will be added: Agent Greeting and Whisper Announcement. A call with Agent Greeting enabled is equivalent to two calls with it disabled. That is, call handling capacity, in calls per second, is cut in half if Agent Greeting is enabled for all calls.


Cisco Unified Contact Center Express 8.5Performance factors for Unified Contact Center Express (Unified CCX) Release 8.0 and earlier features remains unchanged. The

server set that supports 8.0 will support 8.5 as well with some notable additions marked below. Some capability changes relating to outbound agents and IVR ports are noted below. Changes in 8.5 are as follows:

New Features High Availability over WAN of Unified CCX servers Outbound Predictive/Progressive IVR based dialing. It takes the number of outbound IVR ports as input and calculates the

BHCC that Unified CCX, gateways, and Unified CM must handle. Licensed outbound and inbound ports are tracked separately.

New Limits Maximum number of agents supported is 8.5 has increased to 400. This higher limit is supported on the VM - UCCX_400

platform. Maximum number of preview outbound agents is now 100 (instead of the number of total agents). New limits on support of outbound IVR ports and outbound BHCC (busy hour call completions) in various deployment modes

have been defined. These are as follows: • 7816 Class servers do not support Outbound IVR Ports and can support a maximum of 1800 BHCC in standalone and high

availability (HA) over LAN modes, and 750 BHCC in HA over WAN mode. • 7825 Class servers and VM - UCCX_100 support up to 75 Outbound IVR Ports and a maximum of 2000 BHCC in standalone and

HA over LAN modes, and 750 BHCC in HA over WAN mode. • 7835 Class servers support up to 75 Outbound IVR Ports and a maximum of 2600 BHCC in standalone and HA over LAN modes,

and 2250 BHCC in HA over WAN mode. • 7845 Class servers and VM - UCCX_300 support up to 150 Outbound IVR Ports and a maximum of 5000 BHCC in standalone and

HA over LAN modes, and 3250 BHCC in HA over WAN mode. • VM - UCCX_400 supports up to 150 Outbound IVR Ports and a maximum of 6000 BHCC in standalone and HA over LAN modes,

and 5000 BHCC in HA over WAN mode.

New Servers VM definition will be in the format that matches OVA templates. Three templates have been defined, VM - UCCX_400, VM -

UCCX_300, and VM - UCCX_100, each specifying the number of agents that it can support. Appliance based servers (CXA1) are not supported for applications such as Compliance Recording (CR), Quality Manager

(QM), Advanced Quality Manager (AQM), Workforce Management (WFM), and Supervisor Recording/Monitoring. A new VM server, VM - UCCX-WFO, will be defined for these applications.

Actual hardware platforms choices, including B200 M1, B200 M2, C200 M1, C200 M2, and C210 M2, will also be offered


Other ApplicationsCISCO UNIFIED PRESENCE

New Features

Support for IM only mode and full UC mode

Support for both EWS and WebDAV versions of connection to Microsoft Exchange

New VM Platforms

New VM platforms, VM - CUP_5000, VM - CUP_2500, and VM - CUP_1000, are added. They are equivalent to MCS-7845, MCS-7835, and MCS-7825 class of servers.

CONFERENCING & COLLABORATION 8.X

Usage Estimation

Sizing models are enhanced to better estimate the maximum number of conferencing sessions at the top of the hour.

Capacity Change for High Complexity Codecs

Session capacity has decreased by 33% for high complexity codecs (supported in Hardware Media Resource).

CISCO GATEWAYS & DSP

Releases

New IOS releases 15.1(2)T and 15.1(3)T are added. Gateway capacity with new releases is identical to IOS 15.1(1)T.

New Gateway

A new, ASR 1001, platform is introduced as CUBE only. Its capacity is approximately 67% of the ASR 1004.

DSP Calculator

Support for new Network Modules (VWIC3) is introduced. The VWIC3 supports up to 4 T1/E1 WAN interfaces.


Other ApplicationsCISCO NETWORK MANAGEMENT APPLICATIONS

Performance factors for 8.0 and earlier features will remain unchanged. The same server set that is calculated for 8.0 remain valid for 8.5 as well.

CISCO EMERGENCY RESPONDER 8.5

Server Support

Three new VM platforms will be introduced for Cisco Emergency Responder: VM - CER_12000, VM - CER_20000, and VM - CER_30000. These VM platforms are identical to the VM platforms for Unified CM, supporting 1000, 2500 and 7500 Unified CM users, respectively. When used to support Cisco Emergency Responder, these VM platforms will provide capacity equivalent to the MCS-7825, MCS-7835, and MCS-7845 classes of servers, respectively.
