I''d like to try a bake-off of performance of Lustre vfs AFS with encryption turned on, but there seems to be no link to download the 1.8 version, which is referenced in the KerbLustre wiki page last updated in December, and there is only a 1.6 or so beta version available. I would also like to attempt to see if Lustre can come anywhere close to the 10 gigabits per second of disk read I can get to a single client with PVFS over infiniband *, but I''m not going to bother if I have to wait 6 months for the code to show up. * http://www.scl.ameslab.gov/~troy/ib-pvfs-joint-techs-07.pdf

Looking at this PDF, I don''t see anything that would be unsupported by Lustre, though it is best to use the PPC64 kernel with Lustre as our mixed 32- and 64-bit kernel/user support is lacking. We''d be happy to hear any results you could share with us. Cheers, Andreas -- Andreas Dilger Principal Software Engineer Cluster File Systems, Inc.
