<p>Sudheendra,</p>
<p>You will get varied answers depending on who you ask. For us, we
are strong believers in ZFS. Of course, as a major contributor to
ZFS-on-Linux, we're heavily biased, but we believe the management
features (snapshots, etc) outweigh any performance deficiencies
compared to ldiskfs, especially when using SSDs. Plus, ZFS is
continually landing major improvements that boost performance and
resiliency.</p>

<div dir="ltr">Hi,
<div><br>
</div>
<div>I am trying to evaluate SSD based Lustre setup in
our lab. I am looking for some answers for the
following questions:
<div>
<ol>
<li>Which of the 2 underlying file systems is
popular among the global HPC community and
reasons behind it ?</li>
<li>Since I am using SSD based setup, if any
data/links mention the overhead of using one
over the other.</li>
</ol>
<div>Appreciate any online links to understand the
validation done.</div>
</div>
<div><br>
</div>
<div>Thanks for your help.</div>
