ok i have managed to get 101mb/s with iometer with both read and write. turns out my storsave profile for the 3ware was set to protection (which disables WB cache and forces data written to disk to be verified).
its really interesting because i have a FAS270 im comparing it to and its losing in the 4-512 range but killing the fas270 in anything larger (1024-16384). may be acceptable due to the 65k difference in price! not to mention this is 15k FC drives vs 7.2k Sata
the only thing not OOB so far is that i have changed the "receive descriptors" to 2048. soon i will be able to jumbo up the MTU but i predict ill just get better performance on the top end than im already getting.
i think that there is more tweaking that can be done at the ietd.conf level.
is the open-e iscsi target file based or blockio? if its file based what filesystem is being used?
and why does open-e not like iscsi-r3 as much as they like dss! (no update in the ftp folder yet).
New release for iSCSI-R3 will have BlockIO. Please be patient all updates follow DSS. The reason is that once DSS is completed then the iSCSI-R3 and NAS-R3 follows, as the R-3 family is DSS combined. We hope to have this ready next week.
Please remember that if you have iSCSI Logical Volumes in pre-release and you want to use the new version that is blockIO, you will need to create new iSCSI Logical Volumes and delete the existing iSCSI volumes.
Also for Replication as well you cannot have mixed versions for replication.
