Yes, and how is the further design? In others words: The provided list can read as One physical computer with fibre channel disk hosts all the VMs. If it is so, then tell so. Otherwise eloborate the setup, the design. > One question: can vmware tools have any influence in this case? From what I > know vmware tools is mainly for better graphics performance isn't it?

( Which tool was used to read that performance valule? ) I would like to see the output of vmstat 2 5 during non-back-up-time and also the output of vmstat 2 5 during back-up-time. Thing I'm interrested in, are the CPU columns. Especial the colums "system" and "wait". <screenshot> $ vmstat 2 3 procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free buff cache si so bi bo in cs us sy id wa 0 0 6712 11360 192584 159120 0 0 5 4 6 11 5 6 90 0 0 0 6712 11344 192584 159120 0 0 0 0 67 342 7 15 79 0 0 0 6712 11344 192584 159120 0 0 0 0 65 340 8 14 78 0 </screenshot> And to avoid an extra e-mail exchange: I'm asking for 2 to the power 3, so 8 measurements. So 2 moments (during backup or outside backup) on 2 Bacula compoments ( storage deamon and file deamon ) on the VMs on 2 physical hosts. Yes, that means that I assume the VMware hosts have a 'vmstat' command. That is because I'm not familair with VMware, I'm from the Xen world :-) Cheers Geert Stappers -- http://www.vanadcimplicity.com/ ------------------------------------------------------------------------------ Got visibility?
