Can anyone provide an example of a best-case iSCSI Target configuration? Preferably with accompanying performance data.
Right now I'm really stuck. I need to put iSCSI into production. I've got a 24TB, 4 Core 2.4Ghz Opteron, 16GB RAM Thumper sitting here as a target and an X4100 4 Core 2.4Ghz Opteron 16GB as an initiator. The Thumper was loaded fresh with B49 this morning, the X4100 is running B43. I push the ZFS pool in excess of 400MB/s local... I can't eek more than 30MB/s out of it via iSCSI despite the fact that I've got 2 gigabit (e1000g) ports aggregated. I can push NFSv3 above 100MB/s without tuning so long as I disable ZIL. The only place I'm guilty for the moment is that I'm not using JumboFrames. I'll enable those in the next couples days. Based on an earlier post that might be whats killing me. Is that possible? I never used JumboFrames with NetApp Filers and performance was excellent. If this config can't pull big numbers of out the iSCSI Target I don't know what can. Suggestions on how to make this thing sing would be helpful. The follow up is with regards to memory consumption. I created a 100GB ZVol for backing store and ran some benchmarks against it... the target RSS went above 7GB. benr. _______________________________________________ storage-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/storage-discuss
