It isn’t that obscure. A HPE C7000 rack with 8 x BL860c Ithanium sever and Infinband module. Half of the server still running a rhel4 like single system image cluster (but totally outdated) but at least with 20 GBit HBAs (Mellanox) for a fast cluster file system. Ideal for the most kind of system services (mail …) because of the intrinsic loadbalance of the cluster. Here the Infiniband still works with ofed 1.4 On the other hand my attempt to replace it with a up to day system (gentoo). I have corosync and pacemaker (and crmsh) to cluster it and the Infiniband problem is the only thing missing.
