| 296747 | 2004-11-26 21:39:00 | Under Computer Management > Disk Management on my Xp Pro SP1 system there are two columns titled "Fault Tolerance" and "Overhead". What do they mean? Screenshot here (www.zu.co.nz). Thanks |

| 296748 | 2004-11-26 21:58:00 | Fault Tolerance refers to higher level RAID arrays and the like, where each disk has a tolerance (data is mirrored), and when that happens a significant Overhead is required, as the data is duplicated across multiple disks | godfather (25) | ||
| 296749 | 2004-11-26 21:59:00 | Fault tolerance is possibly to do with RAID configurations which use parity for error recovery which again may be related to overhead | Davesdad (923) | ||
| 296750 | 2004-11-26 22:02:00 | This is from the MS site.. For more info go to http://www.microsoft.com type in fault tolerance under search. Fault tolerance is the ability of a system to continue functioning when part of the system fails. Normally, fault tolerance is used in describing disk subsystems, but it can also apply to other parts of the system or the entire system. Fully fault-tolerant systems use redundant disk controllers and power supplies as well as fault-tolerant disk subsystems. You can also use an uninterruptible power supply (UPS) to safeguard against local power failure. Although the data is always available and current in a fault-tolerant system, you still need to make backups to protect the information on your disk subsystem against user errors and destructive events such as fire, earthquakes, tornadoes, and floods. Disk fault tolerance is not an alternative to a backup strategy with offsite storage. You can use dynamic storage to create volume-oriented disk systems that are fault tolerant. The new Disk Management architecture allows online changes without the need to restart your computer. To learn more about dynamic storage |
