Hi Greg,
I'm rather curious about your srp difficulties (not to get too off
topic). Is it an issue with srp by itself or the interaction of srp with
the SRIOV IB HCA? We've used SRP quite a bit both virtualized and not
and have seen good results both in terms of stability and performance.

We use KVM running on a Debian host, with CentOS guests. Storage is
zoned from our DDN Infiniband array to the host and then passed through
to the guests. We would like to zone it directly to the guests SRIOV IB
HCA, but srp seems to be a bit of dead code tree. We had to do a bit of
work to get it working with Debian and haven’t as yet spent the time on
getting it going with CentOS.
We also run Spectrum Archive on the guest with tape drives and libraries
zoned to the guest’s PCIe HBAs which are passed through from the host.
We are working towards going production with this setup.
Xen was a bit a failure for us so we switched to KVM.
Cheers,
Greg

Anyone running SpectrumScale on Virtual Machines (intel)? I’m curious
how you manage disks? Do you use RDM’s? Does this even make sense to
do? If you have a 2-3 node cluster how do you share the disks across?
Do you have VM’s with their own VMDK’s (if not RDM) in each node or is
there some way to share access to the same VMDK’s? What are the
advantages doing this other than existing HW use? Seems to me for a lab
environment or very small nonperformance focused implementation this may
be a viable option.
Thanks
Mark
