We don't have the (HW) resources to test with iSER so it's not something that anyone is looking at as far as I know. Plus, even if you RDMAed the data between the initiator and target, it wouldn't RDMA the data over to the OSD. Instead, it would be copied to and from LIO's UIO mmap region between kernel and userspace and then re-sent via librbd + librados. I'm also pretty confident that the current librados RDMA support involves yet another buffer copy as well. > Thanks > > Marc > _______________________________________________ > ceph-users mailing list -- ceph-users@xxxxxxx > To unsubscribe send an email to ceph-users-leave@xxxxxxx > -- Jason _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
