Hi Johan
Got two ZFS boxes (ZFS00 recv, ZFS10 send), both with IB and all configured and views made for vSphere which works just fine..
What I can't figure out is how to share a LUN with the other zfs box... see pasted info below...
ZFS00: (the box I want to receive my zfs snapshot)
The below are all ESX servers, cannot see the other ZFS box

Sounds sensible, how do I do that?
I tried creating a view for a thin lu with my other zfs box, but how do I detect it?
First of all, if you run IB, forget the iscsi stuff, it's only creating un unnecessary IP layer that you don't need, and adds latency to your application.
Did you create SRP target service using COMSTAR?
# svcadm enable -r ibsrp/target
What's the output of "srptadm list-target" ?(on storage box), or you can also use "stmfadm list-target -v"
Do you got all necessary IB stuff, like a storage manager(OpenSM), in place? HCA ports shows up in dladm show-link?
If so, your host system should discover it as a local disk, just with "format", if you have created a view with the right eui.xxxxxxxxxxxx for the initiator HCA.

I also stumbled across something else interesting, wondering if its possible to set up two identical boxes and create a pool with local/remote disks as per this article http://www.ssec.wisc.edu/~scottn/Lustre_ZFS_notes/lustre_zfs_srp_mirror.html

I usually mount a iSer target and perform ZFS send to the target. This was the best way to exploit the rdma bandwidth to its full potential.

Hi all,
Is it possible to do zfs send/recv via SRP or some other RMDA enabled protocol? IPoIB is really slow, about 50 MB/sec between two boxes, no disks are more than 10-15% busy.
If not, is there a way I can aggregate say 8 or 16 IPoIB partitions and push throughput to a more reasonable speed…
Br,
Rune
