You can connect another MD1000 to the other port on the PERC6. However, the PERC doesn't support mirroring an existing raid set (e.g. raid 5). You'd have to do this with software. However, running software raid on top of hardware raid is really not a good idea. The closest (full hardware raid) option is to set up a raid 10 where each half of each mirror is on a different enclosure. So, for example, if you build a 28-drive raid 10, it's made up of 14 2-drive-mirrors. You would pick the first drive in each mirror from the first enclosure, and the 2nd drive from the 2nd enclosure. If you lose a whole enclosure, you still have access to your data (but effectively as just a raid 0). One note; raid is NOT a substitute for a backup; data corruption can still wipe out your data, even if you mirror your data (on a block level) to another enclosure. Disasters like fire or flooding would also cause dataloss, making an 'offline' backup an requirement.
Hello, I have a problematic: I have a MD1000 powervault pluged on a R610 via a PERC6, I would like to make a backup of the MD1000 so i would like to know if is it possible to use the 2nd slot on the Perc Card to plug a another MD1000 and made a realtime mirror? maybe by specifing a sort of RAID-1 ? Best regards,
Mirror between 2 MD1000
