Some thoughts on the subject. * Not installing an external ibstack is quite attractive imo. RHEL/CentOS stack (not based on any direct OFED version) works fine for us. It simplifies cluster maintenance (kernel updates etc.). * If you use an external IB-stack consider the constraints it may put on your update plans (for example, you want to update to CentOS-7.3 but your OFED only supports 7.2...). * Also consider updates for the stack itself wrt. security. Upstream OFED has been quite good at patching security bus but they DO NOT maintain older releases (-> you may have to run a nightly build of latest). Mellanox has patched when poked at but also only for latest version. Intel does not seem to do security afaict and with a dist stack it's covered by the normal dist updates. /Peter K
