I am new to this raid thing (actually, my raid hardware is only on its way) and have a basic question.

I know i can do this with the software raid in w2k but can the following be done with integated highpoint controllers:

Over two 40GB disks have one 60GB raid0 stripe and with the remainng space on each harddrive have have a 10GB non-raid partition for a total of three logical drives? This would be to make some temporary back-up space, the idea being that the two 10gb partitions would contain redundant information which would be a backup of data in the raid partition. I am asuing that if one disk did fail, that even though the raid would be broken the non-raid (backup) partition would be accesible. Is this thinking correct?

thanks all!

heres what i think.

I dont think it is possible for the fact that urcontroller sets the raid0 up with the disks, not the partitions. U can set up different partitions on that array, but not mirror anything for backup. This is becuase the system sees them as 1 drive always.

If u are looking to backup your raid0, then u wud have to get 2 more disks to mirror the other 2 in raid0. raid0+1.

i have read of a way to "see" the drives seperately, but its in dos i think. U'd be better off just gettn a small hd and putting it on a ide channel and backing stuff up to it. Or u cud just buy 2 small drives for the raid0, just for the programs, and buy a big drive for the ide channel to save everything. Basically just using the raid0 for loading and running apps.

Thanks for the input.
I'm not trying to accomplish real-time redundancy or anything. My thought was to set up a system where, when the system was idle, it would make a copy to each of the drives just to increase the amount of comfortable time between cd backups. you're right in that i could do the same thing with an old ide drive... but i plan on watercooling them and don't want to add a third. oh well.

cool, sounds like a sweet set up.

I hope some else reply's also, cuz im not a 100% sure, but i think 2 disks on raid0 boils down to 2 disks on raid0, no way around it.

No this is not possible! You can partition the array as if it were an 80 GIG drive (60, 20) but if a drive fails, your array is toast and there is not a thing you can do about it, except cry. The best solution for you would be to raid0 the 2 40 GIGers and get an 80GIG for backup.
