<p class="MsoNormal">Hello –<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This is a generalized question about the system datastore and the images datastore<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In OpenNebula – you store all your running VM’s in the system datastore , and images in the aptly named images datastore. I am using it on top of VMware, with SAN attached storage. In my test environment for this it is not an issue, there
will never be more environments than I have room for in my system datastore<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Now the tricky part of this question – my current production environment is made up of anywhere from 4 – 10 ESXi hosts in a VMware cluster (depending on location) and I have no less than 30 LUNS attached as Datastores for vmware – since
it can see and use each of them individually on all nodes in the cluster<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When the time comes to stand up my production Opennebula I will be building it on top of the existing environment, but I will not be destroying any current VM’s – especially since VMware created VM’s and OpenNebula created VM’s can co-exist
on the same set of infrastructure<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Why has ON been limited to 1 system Datastore? Why can’t it take advantage of whatever storage is attached to the ESXi hosts and I choose the DS it goes onto. Presently the way its built, I would have to stand up one ON server per DS for
VM’s and share the same images DS – that seems a bit cumbersome to manage and also a waste of resources. Also if you outgrow your system datastore, you can just grow it once created at a HW raid level – it has to be destroyed to be expanded – I should just
be able to add storage and take advantage of the extra datastores for adding new VM’s to run on.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Am I just reading the documentation wrong?<o:p></o:p></p>
