In this thread [3] you will find some experiences from other users. However, I would consider this approach only to combine the storage within each cluster, because of performance.</div>

<div dir="ltr">Hello,<br>I have 2 clusters (each one contains 10 nodes) in two different places & they only connected through the internet.<br>I have the following set of questions: <br>1- can I combine these 2 clusters in one cloud?<br>
2- can I make Virtual storage from these 2 clusters, i.e. combine the hard disk of all nodes in the 2 clusters to form virtual storage?<br>3- can I make Virtual Ram from these 2 clusters, i.e. combine the main memory of all nodes in the 2 clusters to form virtual Ram?<br>
<br>(can OpenNebula solve these questions?)<span class="HOEnZb"><font color="#888888"><br><br><br clear="all"><br>-- <br>Eman Hossny,<br>Teacher Assistant,<br>Computer Science Department,<br>Faculty of Computers and Information<br>
