<div dir="ltr"><div><div><div><div><div><div>Hi,<br><br></div>I have been asked to setup a Grizzly Instance for academic research. This project will evolve as it goes, so I don't have a clear set of requirements, my initial plan is to try installing using Neutron configured as "Single Flat Network" <a href="http://docs.openstack.org/trunk/openstack-network/admin/content/app_demo_flat.html">http://docs.openstack.org/trunk/openstack-network/admin/content/app_demo_flat.html</a> using the Open vSwitch Plugin.<br>
</div><br></div>The equipment I have is 3 Nodes (2 Nic's per node ), with a switch for a physically isolated node subnet and access to other switches for the rest of our network. The nodes have Fast CPU's with a decent number of Cores and more RAM than we should need<br>
<br></div><div>So currently I am picturing a setup like this<br><br></div><div>Network<br><br></div><div>subnet 1 - openstack management <br></div><div>subnet 2 - openstack data<br></div><div>subnet 3 - Public Network<br>
<br></div><div>Nodes<br><br></div><div>A (Controller + Storage + Compute)<br></div><div> Keystone<br></div><div> Glance<br></div><div> Horizon<br></div><div> Neutron<br> Compute<br> Cinder<br> Shared Storage/NFS<br>
Swift storage<br></div><div> Swift Proxy<br></div><div> (any other needed services)<br></div><div><br></div><div>B (Network + Compute)<br> Neutron <br> Compute<br></div><div> Swift Storage<br><br><div>C (Network + Compute)<br>
</div><div> Neutron<br> Compute<br></div> Swift Storage<br></div><div> <br></div><div>So my questions <br><br>1. Does anything seem fundamentally broken with this approach?<br><br></div><div>2. Is there anything else that I haven't mentioned that I should be thinking about before making a start? <br>
</div><div><br>3. Do people see any advantages for a use case like ours sticking with nova-network, or using an alternate plugin with Quantum such as Linux Bridge Plugin?<br></div><div><br></div><div>4. Is it possible / practical to merge the management and data networks? <br>
<br></div><div>5. Currently the isolated switch is 1G, is this likely to be a significant bottleneck to getting a small number of VM's running? <br></div><br><br></div>Thanks for your time, and any insight you are willing to share.<br>
<br></div>Clint<br></div>
