<div style="font-size: 10pt; color: rgb(0, 0, 0); font-family: Verdana;">Wow. We'll definitely have to take a look at things. No wonder people have talked about putting IPCCx agents on their own cluster in the past. Upgrade planning benefits aside, it sounds like a good idea.

<br><tt><font size="2">I'm using v7.x on 5 Clusters. I too read that these 7845 servers can support 7500 phones per server and 30,000 phones per cluster. Cisco told me that this is true in a perfect world</font></tt> <br>
<tt><font size="2">but Call Center agents use CTI and 500 agents is the max per server with 2000 agents max per cluster. I freaked out because thats a 15:1 ratio. </font></tt> <br><br><tt><font size="2">Another thing Cisco came back with is that if these agents use CVP and don't use an IP IVR then that number doubles to 1000 agents per server and 4000 agents per cluster.</font></tt> <br>
<br><tt><font size="2">A little better but as Wes said, a massive performance hit.</font></tt> <br><br><tt><font size="2">Here's more info:</font></tt> <br><a href="http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/ipcc_enterprise/srnd/75/c7ccmsrv.html#wp1061120" target="_blank"><font color="blue" size="3" face="Calibri"><u>http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/ipcc_enterprise/srnd/75/c7ccmsrv.html#wp1061120</u></font></a> <br>
<br><font size="3" face="Arial">In a deployment with Unified CM 7.0 and Unified CVP (no IP IVR), each Unified CM cluster (four primary and four backup subscriber servers) can support up to about 4,000 Unified CCE agents. This limit assumes that the BHCA call load and all configured devices are spread equally among the eight call processing servers with 1:1 redundancy. (See </font><font color="#002f80" size="3" face="Arial"><u>Unified CM Redundancy</u></font><font size="3" face="Arial">, for redundancy schemes.) Each of the eight Unified CM servers (MCS-7845-H2/I2 or later High Performance Servers) would support a maximum of 500 agents. In a failover scenario, the primary server would support a maximum of 1,000 agents. These capacities can vary, depending on your specific deployment. All deployments must be sized by using the Cisco Unified CM Capacity Tool or the Unified Communications Sizing Tool.</font> <br>
