i (used to) use this target... it just isn't very fast at all. linear, single threaded 4k iops to a 8 disk raid5, reading just over 3000 iops. not very interesting. single-sata-attached can get >6000 for example. however, with good readahead, if you are doing bulk transfers (backups, dd, etc) then you should get closer to wirespeed. blockdev --setra 4096 should be enough, but you could go 2x or 4x more. this is basicly true of any iscsi target though. i never did any extensive write testing. there are plenty of tuning threads and details floating around, IET mailing list probably has the most discussion in this area, so it is a good place to look. other main complaint about this box is severe limit of logical units. 25 per volume... -benjamin --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "open-iscsi" group.
