Is there a limit on the number of oss servers you can have in a single filesystem? is there one for ost's?
I'm curious of the performance implications between two different configurations (this is just theory mind you)... 1000 oss with 1 ost each vs 100 oss with 10 ost each one could scale this up further 2000, 5000, 10000 oss's with 1 single ost each i did note two references one from 2012 by Oleg Drokin that tested 1300 OST's at ornl which "mostly worked" and a note from Andreas last year that quoted 2000 OST's before scaling issues. I'm curious if there's a fundamental issue with scaling lustre, which might be based on the presumption that oss's are typically fatter nodes (getting fatter everyday) rather than large quantities of skinny nodes I'm also curious if there is still a 160 OST limit for file striping as well. _______________________________________________ lustre-discuss mailing list [email protected] http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
