<p class="MsoNormal">Dear all,<br>
<br>
I am wondering how many of the top100/top500 systems use Lustre with ZFS and how many with ldiskfs? Any hints how/where to get this information? I would be also grateful for any further statistics related to the popularity of the backends.<br>
<br>
Thank you<span style="font-size:13.5pt;font-family:"Courier New""><br>
