Is this just generally an idea that data stored on SSD should not be in RAM? If so, there's no mechanism for that other than using direct I/O.</div>

<b>Subject:</b> [lustre-discuss] Avoiding system cache when using ssd pfl extent</font>
<div> </div>
</div>
<div class="BodyFragment"><font size="2"><span style="font-size:11pt;">
<div class="PlainText">When using PFL, and using an SSD as the first extent, it seems it would
<br>
be advantageous to not have that extent's file data consume memory in <br>
the client's system buffers. It would be similar to using O_DIRECT, but <br>
on a per-extent basis. Is there a mechanism for that already?<br>
<br>
Thanks,<br>
