Hello Is there any experiences about using the Infiniband technologies with XEN? Thank you -- Houssem MEDHIOUB _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
I use it for DRBD disk cloning and with IPOIB for Migrations. I have requested RDMA Migration support for Xen 4.0 which would allow VERY fast VM migration over Infiniband. What were you looking at using Infiniband for with Xen, Storage?, Cluster Interconnect? Migration? General TCP/IP?

DRBD does not have RDMA support so IPoIB is used. IBoIP is faster then gig eth, but would be great to have native RDMA support in xen for migration.><>Nathan Stratton CTO, BlinkMind, Inc. nathan at robotics.net nathan at blinkmind.com http://www.robotics.net http://www.blinkmind.com _______________________________________________ Xen-users mailing list Xen-users@lists.xensource.com http://lists.xensource.com/xen-users
Hello Thank you for your answer I am looking for the Infiniband for the cluster Interconnect and more especially for the Virtual machines migration.

Hi Houssem, I think Infiniband passthrough support is already pretty good under Xen which should allow for reasonably efficient cluster interconnect but I have not tried it; I''m sure some one else more knowledgeable can answer more accurately on this. Currently machine migration is by TCP/IP only. I use IPOIB (IP Over Infiniband) with Xen migration and it works well (Performance is about the same as 10Gb Ethernet). If RDMA migration support is added migration performance would be approx 2 to 4 times faster, it might get considered for Xen 4.0 (I have already asked), if you would like RDMA migration support then let Stephen Spector know: stephen.spector@citrix.com You might get very knowledgeable responses on infiniband specific questions here general@lists.openfabrics.org (Avoid asking very generalised questions, research first!)
