<div class="moz-cite-prefix">Yeah i thought of that way, could it be
SAN that attach to /var/lib/nova/instance? <br>
so in this way swift is just for database / object thing .<br>
thanks so much.<br>

the compute node’s sizing must be done in terms of CPU,
Memory and Disk based on the flavor being selected. If you
want to host 50 vms that have flavor specs 1 vcpu, 2 gb RAM,
10 gb root disk each, you need a compute node with 500 GB
instance repository, 72 GB Memory, 16 core CPU.

of local repository, you may like to mount

to another server?<br>
so thats mean we need large hardisk for compute node, is
that right?<br>

<pre>1. i have compute node and running KVM hypervisor in there, controller node and network node.<o:p></o:p></pre>
<pre>question is, in where data that instance run store? is it on compute node?<o:p></o:p></pre>
<pre>2. if i want to store all data in separate node let say using swift (swift node), can this happen?<o:p></o:p></pre>
<pre>3. what is flavor used to store data? i mean when i create instance with selected flavor(ex:10GB), where that space that would be create? in swift node?<o:p></o:p></pre>
<pre>4. So if this can be done, in my compute node is just run KVM, and no data store that. right?<o:p></o:p></pre>
