If I''m wrong please let me know, but my understanding of how lustre 1.8 works is metadata is only accessible from a single host. So should there be alot of activity, the metadata server becomes a bottleneck. But I''ve heard that in ver 2.x that we''ll be able to setup multiple machines for metadata just like for the OSSs, and that should cut down on a bottleneck when accessing metadata information. -- Personally, I liked the university. They gave us money and facilities, we didn''t have to produce anything! You''ve never been out of college! You don''t know what it''s like out there! I''ve worked in the private sector. They expect results. -Ray Ghostbusters
I believe that was the *goal* of 2.0, but unfortunately, that lofty goal was not met, the timeline of which seemed to stretch from when Sun purchased Lustre until some time in the far future.
