I highly recommend to build a prototype for your system. You can test hypervisors, transfer drivers etc on 2-3 computers. OpenNebula drivers are written in ruby and bash script that you can customize for your environment. Count in that OpenNebula developers are very helpfull :). You have a lot of options to fine tune your system. For example I changed the image transfer drivers to run on NFS server locally not on the network wich doubled the clone speed. If you setup that system I would be glad to hear your experiences and speed statistics :).<br>

Hi,<br>
We are small University located in Belgrade, Serbia , <br>
our current information system <br>
is created mostly of different hardware manufactures,we use<br>
Citrix Xen Server Free Version primarily for ability to run on<br>
bare metal configuration. <br>
Recently we are in process of buying IBM Blades servers with
StoreWise V7000 and we would like to <br>
switch to OpenNebula Cloud , mainly because we use a lot of open
source technology and <br>
are budget is tight.<br>
This is our configuration <br>

Most of our vms/ applications use tomcat, mysql ,lamp, alfresco dms
,SAP , windows 2008 server.<br>
<br>
<br>
<br>
The question is is this configuration good for implementing
OpenNebula solution? <br>
<br>
Can Front-End run virtualized on kvm or xen nodes ?<br>
<br>
Does nodes access directly to shared storage iSCSI ?<br>
<br>
<br>
Some remarks,recommendation and experience would be nice. <br>
<br>
<br>
Thank you Very Very much for the help. <br><span class="HOEnZb"><font color="#888888">
