<div>I wouldn't see a reason not to just up-size the two nodes you have now to the 2.5k OVA (use 2 vCPU on each node). For the
<i>15 pieces of flair</i>, I'd then add in a 3rd 2.5k OVA w/o the CCM service enabled and run TFTP.. etc on it and give the pub a break.</div>

One of my biggest customers is experiencing issues that appear to be related to resource utilization. I’ve never had a customer who needed more than a 2 node 1000 user cluster.
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
They are getting close to some of the capacity levels listed in the sizing guides.
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
I’m looking for some opinions on what the best way to deal with this. I have the hardware capacity for either method.</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
Add a Third 1000 user Subscriber and turn off call processing and tftp on the Pub?</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
Rebuild both existing servers to 2500 user OVAs?</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
Add a third and do the rebuild also?</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
Can I just make the existing server be the 2500 capacity level? I actually don’t understand the difference between the 2500 and 1000 user OVAs, the 2500 appears to actually be lesser capacity by default (1 less cpu). So go to 7500?</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
I’d appreciate any opinions out there. Going to be doing some reading over the next few days to try and figure this out.</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
Thanks all!</p>
