Hot spares do not provide less downtime compared to a supported drive failure (ie. 2 disks on raid 6). they just reduce the mean time to repair. Handy if your disks are at a remote site or your dealing with very large arrays but likely a waste of spindles if your sitting next to your data all day.
- dspillett 15y agoNot hot spares (which you are right, don't reduce array repare downtime): hot swap (which can). If a hot spare gets used you still need to swap out the broken device (its replacement becoming a new hot spare). Wether you are swapping out a replacement for an active drive or swapping out a dead drive with what will be a new hot spare (a drive that was previously the spare now being an active drive in teh array) whether you have hot-swap or not makes a difference. Without, you have to power down the array for a short time which in an environment that needs availability to be as high as possible could be an issue.
- WettowelReactor 15y agoSorry I misread your post. I just couldn't fathom a storage solution without hot swappable drives.
