Yes Brock -- as Mike has mentioned we also took this doc and provided
this for our TACC customer:<br>
<br>
<a class="moz-txt-link-freetext" href="http://www.tacc.utexas.edu/resources/hpcsystems/">http://www.tacc.utexas.edu/resources/hpcsystems/</a><br>
<br>
where we put 72 x4500s in place with this configuration with them.<br>
<br>
In addition, Sun's recent Linux HPC Software<br>

has the mv_sata driver and the SW configurations needed to put the <br>
x4500 together as an OSS one can build up upon and further configure <br>
with the SW RAID patches also included.<br>

<pre wrap="">Brock,
It is recommended that mv_sata is used on the x4500.
It has been a while since I have built this up myself and a few Lustre
releases back but I do understand the pain. I hope that with Lustre
1.6.5.1 on RHEL 4.5 you can just build mv_sata against the provided
Lustre kernel and alias it accordingly in modprobe.conf and create a
new initrd, then update grub. I don't have gear handy to give it try
unfortunately. Please let me know your experiences with this if you
pursue it.
Enclosed is a somewhat dated document on what we have found to be the
best configuration of the x4500 for use with Lustre. Ignore the N1SM
parts. We optimized for performance and RAS with some sacrifices on
capacity. Hopefully this is a useful reference.

stata_mv from RHEL4 does not appear to show some of the stability
problems discussed online before.
I am curious because the build system sun provides with the driver
does not play nicely with the lustre kernel source packaging.
If it is worth all the pain, if others have already figured it out.
Any help would be grateful.
