<br>
UC apps do not support CPU oversubscription. One VM vCPU must map to one physical core (not one logical core) (<a title="Unified Communications Virtualization Sizing Guidelines" href="http://docwiki.cisco.com/wiki/Unified_Communications_Virtualization_Sizing_Guidelines" target="_blank">

<span></span>OK, my reading was wrong for the C240 M3S. It has a total of 16 CPU, so 16x2.7GHz.<br>
<br>
So either a total of 8 OVAs based on 1:1 vCPU:pCore, or 12 based on reservation.<br>
<br>
The more I'm thinking about it, I'm thinking it's 8 since you want some extra CPU cycles for each server.<br>

<div style="FONT-FAMILY: Verdana; COLOR: #000000; FONT-SIZE: 10pt"><br>
I'm wondering if someone can help explain some of the UC on UCS CPU requirements that I'm seeing. I getting a little confused by some of the terminology and stuff in brackets.<br>
<br>
When I read the <a href="http://docwiki.cisco.com/wiki/OVA_Template_Details_for_Unified_CM_Release_9.0" target="_blank">
OVA requirements</a> for a 7500 user node, <span>it says 2 vCPU (with 3600MHz reservation) and physical load calibrated to
</span>E5540 2.53 GHz.<br>
<span id="7cfbb40c-a4b1-4204-bd00-d872375142d4"><br>
If I want to install this OVA on a </span>UCS C240 M3S (SFF) TRC#1 which has Dual E5-2680 (8-core, 2.7 GHz) do I do some sort of reservation of total CPU Hz available? Or is it simply a 1:1 core assigned, vCPU to pCPU?<br>
<br>
The total Hz available is 8x2.7G=21.6GHz which means I could install 21.6/3.6=6 of these OVAs?<br>
<br>
Or do you do CPU math, 8/2 = 4 OVAs allowed to be installed?<br>
<br>
The math and disk space calculations seem much easier.<br>
