<p><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">Hi,<o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">The simple answer is that right now, OpenStack does not treat blades in any special way.<o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">If the hypervisor in use is blade aware, this may make a difference, but in general each server appears as a server. It is possible to group servers together into HostAggregates (<a href="http://docs.openstack.org/trunk/openstack-compute/admin/content/host-aggregates.html">http://docs.openstack.org/trunk/openstack-compute/admin/content/host-aggregates.html</a>)
to take some different action scheduling-wise, or manage taking entire blade chassis offline at the same time.<o:p></o:p></span></p>
<p><span style="font-size:10.0pt;font-family:"Arial","sans-serif"">It sounds like you have a good idea of the actions that can be performed with blade servers that OpenStack could be taking advantage of. It would be great to get you to share your ideas with
the OpenStack developers to improve the current situation. The development mailing list is found here:
