Has there been any testing or conclusions regarding the use of virtualization and Lustre, or is this even possible considering how Lustre is coded? I''ve gotten used to the idea of virtualization for all our other servers, where it is great to know we can mount the image on another host very quickly if a hardware problem brings down a machine, and it seems the same would be nice with Lustre...

Just took the xen kernel and applied the patches and built rpms like it is described in the manual. My OSS servers are configured with lustre failover on physical machines, managed by pacemaker. cheers, Sebastian

Should be no issues. In fact, use of KVM/VMware/Virtual box for local testing is quite common among Lustre devs. However, we really like to be close to the metal for performance reasons. I would not use visualization in a production environment where performance was crucial. I am also not certain how well high-performance networking does in a virtual server - we make heavy use of RDMA when available. cliffw> > > _______________________________________________ > Lustre-discuss mailing list > Lustre-discuss at lists.lustre.org > http://lists.lustre.org/mailman/listinfo/lustre-discuss
