Re: Hardware RAID

I must have missed this the first time around, but we just went with
hardware raid solution as well. We installed the ICP-Vortex card, we paid
about $590 or so for it from www.thelinuxstore.com with 32MB of RAM. It
takes standard PC100 SDRAM. The card comes with linux drivers, and linux
software so you can actually setup the RAID settings REMOTELY! That's
right, you can do it from a telnet/ssh window if you want to, anything
that supports ncurses...

www.icp-vortex.com is the address, so far, we havent had any issues with
it, and it works as advertised.

|   saw as i was installing debian both drives were active when it was 
|  installing to just the first drive "great" i thought. but the more i
|  read the manual and stuff the more it seemed like in order to restore
|  the secondary drive to use as a primary (if the original primary failed) was
|  to use their proprietary windows software to rebuild the array. the disk
|  they provide to setup the array (that you boot off) didnt have any
|  rebuild features. so when it came down to it... i realized i could not
|  use the hardware raid without the software program utilities. 
| the cost was about the price of two adaptec 2940's and in the end. i ended
| up removing the array completely, and using the controller as just a
| scsi controller and wasting the RAID features. so now i have two drives.
| and i dd'd the contents of th first to the second.. and run a script
| that diffs the specified files that i want to back up and overwrites
| the newer file onto the second hard drive whenever its been updated.
| so if there is a problem with the first drive, i can just put the
| secondary in the primary slot and boot right up on it no problem.
| kind of a hacked raid-1 i guess. it works good and i dont have to worry
| about rebuilding arrays or whatever.
| hope this helps someone about to make the same mistake, or maybe someone
| has had bette rluck with the same card, if so please tell me all about it!
