Yes. If you find a sure way NOT to loose data, can you keep your files on two different drives, on different servers. Hint: both devices must have the same names, on both machines, and the same mountpoints. (i.e. /dev/sdb1, mounted under /failsafe ) > Do we need to have special NIC's to get a ip different ip address for every > resource or do we need as many NICs as we have resources ? No. On a NIC can you define more than one IP Address. i.e. : eth0 10.10.10.1, eth0:0 10.10.10.33, eth0:1 10.10.10.167 ... and so on. Then, all pings on further definied IP's comes ever on eth0 device. Bye, mpr. -- Marcin Przyczyna | Net & Sys Admin, | citiworks AG | [email protected] | +49 89 9925 75356 |
