Hi Branko,<br><br>i'm not sure if it helps, but i have working production environment with customized drivers on SAS shared block storage, it should be similar to what you get with FC.<br>In short: shared block device containing one volumegroup, with multiple logical volumes, one for every registered volume. GFS2 for the shared storage.<br>
<br>My production is curently on ONE 3.4, drivers are public here:<br><a href="https://github.com/jhrcz/opennebula-tm-gfs2clvm/tree/gfs2clvm-one-3.4">https://github.com/jhrcz/opennebula-tm-gfs2clvm/tree/gfs2clvm-one-3.4</a><br>
<br>I'm currently working on bringing it to 3.8, based on the uptodate lvm drivers and on the update to my driver from Bill Cambell. His customization to bring my older driver for ONE 3.6 is public here:<br><a href="https://github.com/billtcampbell/opennebula-tm-gfs2clvm">https://github.com/billtcampbell/opennebula-tm-gfs2clvm</a><br>

<div>Thank you for your replies . <br>
<br>
I would be more than welcome to share the ,speed and testing
results on the system,<br>
currently we are testing OpenNebula on smaller system and with
software iSCSI .<br>
One thing we really like is ability to tune system by are need
which very neat and opennebula <br>
just does that , many thanks to developers of OpenNebula.<br>
<br>
One think that worries me is Fiber Channel support in OpenNebula I
was looking for some example implementations of FC and OpenNebula
but could not find none in <br>
docs for 3.6 <a href="http://opennebula.org/documentation:rel3.6:sm" target="_blank">http://opennebula.org/documentation:rel3.6:sm</a>
nothint about FC could be found. <br>
Only thing I could find is 2.0 docs <a href="http://opennebula.org/documentation:archives:rel2.0:features" target="_blank">http://opennebula.org/documentation:archives:rel2.0:features</a><br>
which say is it supports FC. <br>
Only think I saw is cLVM Jaime Malis and Nicolas Aguis talking
about cLVM in 3.6. <br>
Does driver cLVM work now with multiple hosts sharing Fiber
Channel Storage? Any experience <br>
<br>
/ recommendation with FC ?<div><div class="h5"><br>

<blockquote type="cite">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>

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

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>
