Hello. I have a fairly simple question. What is the fastest single-client, single-thread, single-file read performance anyone has ever observed using PVFS2, and what hardware did it use?
I need to be able to read 500 megabytes/second, sustained, from a single file using a single thread. I have achieved such speeds and higher, reading 200+ gigabytes sequentially, using a fast RAID and XFS (i.e., local storage). I would like to replace that design with something more networked and scalable. But my individual clients still require 500+ megabyte/second reads. If I tie together a half dozen fast OrangeFS servers with 10GigE, will I be able to serve another half dozen 10GigE clients at 500MB/sec each? (Again, assuming single-file, single-thread on each client. Also assume each server can read/write its local store at ~1000 MB/sec sustained.) Finally, and perhaps off-topic for this list... If OrangeFS cannot do this sort of thing, are there any distributed Linux file systems that can? Thanks. - Pat _______________________________________________ Pvfs2-users mailing list [email protected] http://www.beowulf-underground.org/mailman/listinfo/pvfs2-users
