[Lustre-discuss] stata_mv mv_stata which is better?

[Mike Berg]

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.
