Basically all machines: - connected by a 1 GBit link. - All clients doing a dd write of 8GB file from /dev/zero - 3of8 is the special raid-groups arrangement of exofs && objlayout where out of 8 devices each file is striped over 3 devices in a round robin fashion. (*With a small dirty trick) [single client] 1 - osds 40MB 2 - osds 80MB 4 - osds 114MB (saturation point of the 1 Gbit link) 8 - osds 114MB [2 clients 8of8 osds] 226 MBs [4 clients 8of8 osds] 263 MBs [8 clients 8of8 osds] 252 MBs [1 clients 3of8 osds] 114 MBs [2 clients 3of8 osds *] 226 MBs [4 clients 3of8 osds *] 417 MBs [8 clients 3of8 osds] 405 MBs Boaz
