Lustre devel - Dec 2006 - pvfs and lustre comparisons

I''m looking for some feedback from the luster users.  I am leaning
toward luster, but I wonder how pvfs would contend?

 

I''m interested in any thoughts on why one would go to luster or pvfs
for
their hpc file system needs.

 

What fundamentally makes luster different from pvfs?

 

I realize that one may claim (that for specific requirements) luster or
pvfs may be more suitable or better.

So....I''d like to know which requirement(s) led you to luster or pvfs?

 

I would definitely like to know any limitations you''ve seen in either
fs.  Installation complications? Scalabilty. Reliability. Speed.

 

I really appreciate your feedback.

 

Thanks,

Hi Bill

You are asking good questions.  I suspect you will get lots of
information about Lustre from the list subscribers.  

I would encourage you, since you are curious about PVFS, to also ask
this question on the PVFS list (pvfs2-users@beowulf-underground.org) 

Thanks
