Cisco Cisco IP Contact Center Release 4.6.2 Nota Di Rilascio

component server requirements dictate certain hardware capabilities, e.g. SCSI disk drives for high transaction SQL Server or Oracle 
deployment, or dual processor configurations to achieve specific system performance metrics, the MCS server(s) selected from the 
available 7800 series is depicted.  Note that the MCS processor chosen will generally exceed the performance characteristics of the 
corresponding representative “minimal” generic hardware specifications.  Furthermore, both lower and higher end platforms may be 
recommended for a single sizing category.  This is due in part to an effort to align more closely with the general hardware 
requirements and, additionally, to account for eventual increases in system load. The higher end specifications should be followed in 
deployments that are nearing the edge of the Sizing Guidelines specified below.

As stated above, this document addresses the general hardware requirements of the ICM Enterprise Edition and IPCC Enterprise 
Edition products.  For more detailed information on IPCC Enterprise Edition deployments, please reference the Cisco IP Contact 
Center Solution Reference Network Design Guide

Sizing Guidelines 
In determining how to size a Cisco ICM Software implementation, it is important to consider the factors listed here.  While there are 
additional factors to consider, we have chosen a representative subset and provided corresponding ranges.  If, in your specific 
application, actual or estimated associated values are nearing the higher end of the range specified, the next higher end deployment 
size should be adopted.  Discrete elements should be considered relative to one another, with any one capable of pushing 
recommended sizing to the next level.  As an example, a deployment would be considered a “Medium Enterprise” if the number of 
users (Agents and Supervisors) is 200 Users (itself falling in the “Small Enterprise” range) but call variable use is considered 
Medium
.  If half the calls being processed involve the use of call variables (Peripheral or ECC) then this is Medium usage.  
Conversely, if the user count approximates 50 but call variable use is deemed Medium, then it is safe to assume the “Small 
Enterprise” deployment hardware recommendations are appropriate.

General Hardware Performance Guidelines 
The following is a high-level list of recommended use of server hardware options. Consult your hardware vendor for more detail and 
options. 
Redundant Components 
Redundant hardware options are found in power supplies, memory, and like components.  Most of these options are supported, with 
some exceptions. One exception is redundant and/or load sharing Ethernet adapters.  The ICM/IPCC application fault-tolerance 
mechanisms rely on a proprietary heartbeat scheme utilizing the “Visible” and “Private” networks.  Using teamed or redundant

 Medium call variables use can be estimated based on  a variety of parameters.  For one, the total ECC (Extended Call Context) 
Variables size could be around 1000 bytes (maximum is 2000 Bytes).  Another consideration is the extent to which call variables are 
used in call routing.

 Agent State Tracing Disabled – Enabling tracing, depending on the user count, may imply adopting the next higher end deployment 
size.
