hello pluggers, hardware architecture question:
i'm trying to connect 8 dvd writers to a desktop board (q35, 2.5ghz c2q, 8gb pc800) using up all 6 onboard sata ports, the ide port, one usb-ide (cdrking), and hoping to find a pci-sata card also using 2 atx powersupplies if i burn dvds at 4x only (~15 mins) how many more dvd writers can i add before maxing the io? which bus/bridge will be maxed out? (southbridge, northbridge, sata, pci) the harddisk is sata also, 7200rpm, and i'm writing an .iso image to all of the optical drives at the same time. will a ramdrive reduce read io from the harddisk? coz looks like linux isn't using up all free memory to for the disk cache? top - 07:49:55 up 1 day, 8:52, 2 users, load average: 12.24, 11.27, 9.61 Tasks: 180 total, 4 running, 176 sleeping, 0 stopped, 0 zombie Cpu0 : 1.7%us, 1.7%sy, 0.0%ni, 28.4%id, 67.5%wa, 0.3%hi, 0.3%si, 0.0%st Cpu1 : 2.0%us, 1.4%sy, 0.0%ni, 20.5%id, 75.9%wa, 0.0%hi, 0.3%si, 0.0%st Cpu2 : 4.4%us, 3.1%sy, 0.0%ni, 21.1%id, 71.4%wa, 0.0%hi, 0.0%si, 0.0%st Cpu3 : 4.4%us, 2.5%sy, 0.0%ni, 16.4%id, 76.7%wa, 0.0%hi, 0.0%si, 0.0%st Mem: 8109320k total, 1906644k used, 6202676k free, 240088k buffers Swap: 9815672k total, 0k used, 9815672k free, 526696k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 6530 root 20 0 495m 86m 9924 R 4 1.1 29:15.72 Xorg 13185 wingp 20 0 621m 180m 25m S 3 2.3 4:23.10 firefox 4289 wingp 20 0 46804 33m 1040 D 1 0.4 0:04.23 growisofs 6936 wingp 20 0 242m 28m 7996 S 1 0.4 3:20.65 compiz.real 4304 wingp 20 0 46804 33m 1040 D 1 0.4 0:01.51 growisofs 6874 wingp 20 0 376m 28m 14m S 1 0.4 0:45.81 gnome-panel 7036 wingp 20 0 139m 13m 7460 S 1 0.2 0:10.64 gtk-window-deco 7056 root 15 -5 0 0 0 D 1 0.0 0:23.66 usb-storage 7346 wingp 20 0 217m 21m 10m S 1 0.3 0:42.95 nautilus-cd-bur 4294 wingp 20 0 46804 33m 1040 D 0 0.4 0:01.51 growisofs 4296 wingp 20 0 46804 33m 1040 D 0 0.4 0:01.46 growisofs 4298 wingp 20 0 46804 33m 1040 D 0 0.4 0:01.50 growisofs 7153 wingp 20 0 262m 25m 11m S 0 0.3 1:59.32 gnome-terminal 7271 wingp 20 0 217m 21m 10m S 0 0.3 0:44.53 nautilus-cd-bur 7294 wingp 20 0 217m 21m 10m S 0 0.3 0:44.67 nautilus-cd-bur 7317 wingp 20 0 217m 21m 10m S 0 0.3 0:45.13 nautilus-cd-bur 7333 wingp 20 0 217m 21m 10m S 0 0.3 0:44.93 nautilus-cd-bur 7360 wingp 20 0 217m 21m 10m S 0 0.3 0:44.81 nautilus-cd-bur tnx _________________________________________________ Philippine Linux Users' Group (PLUG) Mailing List http://lists.linux.org.ph/mailman/listinfo/plug Searchable Archives: http://archives.free.net.ph
