Hi Team,
Need inputs on Cluster Sizing tool for CUCM. We are planning to consider the requirements of a Mega Cluster. Exiting cluster is 11.5.1 -->
CUCM - 1 Pub 8 Sub
CUC- 1 Pub 1 Sub
UCCX - 2 Clusters - 2 Sub each( 1st Cluster in Location A and 2nd in Cluster B)
Total devices are - 28K including SCCP, SIP, CSF, CIPC
Total DN - 49000
CTI Route Port- 270
CTI Route Point- 2000
Total Agents- 450
Remote sites- 175
BHCC for both inbound and outbund comes 7400 checked from CDR Traffic summary Serviceability page.
How could we find out the values for BHCA for Inbound/Outbound calls?
How to find out BHCA for Intercluster /Intracluster calls/Enterprise BHCA?
how to get details about Percentage of PSTN TDM-IP IPT Load to GW group 1?
How to add all gateways and Analog gateways on Gateway section with all 175 gateway based on platform and ios version.
We need to get accurate details as possible to do a correct sizing and planning for cluster expansion.
Any help or supporting documentations will be real help. I have checked details about calculating BHCA from SRND but real and accurate calculations is need for proper sizing.
Regards,
Vinod Dahiya

Thanks for checking this!
I opened this discussion after verifying output at my end but let me re-login tomorrow in other cluster to see if it's an issue in only one cluster. At my end it was informing to click on link of previous date which gave device count output only
I will share results.

Thanks for your inputs!
Verified from other cluster, I can see CallActivitiesRep, PerformanceRep, Device Rep, Service Rep which shows cluster BHCA, H323, SIP trunk , MGCP BHCA and BHCC.
In required custer, it is showing PerformanceRep of 2nd June(No info for other dates) showing device count only. Cisco Serviceability Reporter service is deactivated in this cluster. I am going to activate this service.
Any idea how to differentiate BHCA for Inbound and Outbound - PSTN calls, Inter cluster and Intracluster?

This is a good megacluster thread:
https://community.cisco.com/t5/unified-communications/cisco-mega-cluster/td-p/3473283
I have been through a few of these. Use your best good faith estimate for your calculations, better to overestimate than underestimate. You could also touch base with your Cisco Account Manager to perhaps meet with someone with the Megacluster team to find out how accurate you may need to be before filling out everything.
