IF the MCS server is rated at 50,000 BHCC how do i work out the max number of BHCA supported ?
If someone from Cisco or anywhere can tell me the number of BHCA that would be great
I realise if I had data I could work out utilisation based on how many calls time etc.
At the moment im looking for max number of BHCA for the lates MCS 7835 single processor platform
THE CM SRND 4.0 mentions the Cisco Callmanager capcity tool
Where can I find this guy
Cisco CallManager Capacity Tool
The Cisco CallManager Capacity Tool requires various pieces of information to provide a calculation of the minimum size and type of servers required for a system. The information includes the type and quantity of devices, such as IP phones, gateways, and media resources. For each device type, the capacity tool also requires the average BHCA and the average utilization time. For example, if all IP phones make an average of 5 calls per hour and the average call lasts 3 minutes, then the BHCA is 5 and the utilization is 0.25. (5 calls of 3 minutes each equals 15 minutes per hour on the phone, which is 0.25 of an hour.)
In addition to the device information, the capacity tool also requires information regarding the dial plan, such as route patterns and translation patterns.
When all the details have been entered, the capacity tool will calculate how many primary servers of the desired server type are required as well as the number of clusters if the required capacity exceeds a single cluster.
The capacity tool replaces the previous mechanisms known as device weights, BHCA multipliers, call type multipliers, and dial plan weights.
At this time, the capacity tool is available to all Cisco employees. Please contact your Cisco representative for more information.
