my VMware environment to get familiar. what do you suggest for 20 node<br>
cluster? we don't have any storage requirement all we need CPU and<br>
Memory to run our application, currently all application running on<br>
VMware and i want to migrate them over Openstack and do some rapid<br>
deployment.<br>
<br>
This is what i am planning (let me if i am wrong)<br>
<br>
2 controller node (in HA)<br>
2 Cisco ASR1k (L3 function in HA)<br>
20 compute node with 10G nic and lots of memory and many cpu cores.<br>
<br>
Anything else which i am missing?<br>
