Intel NICs don't have "hardware iSCSI offloading", broadcom NICs do have it (using bnx2i driver). MPIO on Linux is *often* done using the Linux kernel device mapper dm-multipath driver. It doesn't require anything special from the NICs/drivers. It doesn't even require iSCSI actually, it works pretty much for any SCSI device (iSCSI, FC, FCoE, SAS, etc). So yes, you can do multipathing with iSCSI using Intel nics with the default RHEL kernel modules. -- Pasi _______________________________________________ rhelv5-list mailing list [email protected] https://www.redhat.com/mailman/listinfo/rhelv5-list
