I recently updated the System requirements table in the Compute Admin Manual to say this:<br><br>With 2 GB RAM you can run one m1.small instance on a node or three
m1.tiny instances without memory swapping, so 2 GB RAM would be a
minimum for a test-environment compute node. As an example, Rackspace
Cloud Builders use 96 GB RAM for compute nodes in OpenStack
deployments.<br><br>See <a href="http://docs.openstack.org/trunk/openstack-compute/admin/content/compute-system-requirements.html">http://docs.openstack.org/trunk/openstack-compute/admin/content/compute-system-requirements.html</a>. <br>
<br>Hope this helps. <br>Anne<br><br><div style="margin: 2em 0pt;" name="sig_d41d8cd98f"><div style="padding: 5px; font-size: 11px; color: rgb(102, 102, 102); font-family: sans-serif;">
