swap mirror

[Stefano_1]

which is the sense of mirror the swap?
And which is the right configuration for the Mirror Write Cache and the Consistency Recovery mechanism??

My understanding is that you can't mirror swap on Linux.

You can stripe swap for increased swap performance, however. Create multpile swap areas on multiple disks and set them all at the same priority in the /etc/fstab and the OS will stripe the information.

Whoops.. I retract that. Seems that you can with kernel levels in the upper 2.3s or any 2.4.

See http://www.linux.com/howto/Software-RAID-HOWTO-2.html#ss2.4

Although it's noted that this is not for performance reasons, only high availbility, and there is a caveat or two.
