RE: hardware raid
If you are looking for Ultra 160 SCSI, the Mylex AcceleRAID 170 may be something that you want. I recent purchased about 30 of these cards for a RAID 1 solution for some rack servers. They work pretty good. RAID0, RAID1, Spanning (JBOD), RAID5. You can backup and restore the controller configuration to a floppy disk, the BIOS interface is fairly nice and simple. Rebuilding takes awhile, but no big deal. They also make an AcceleRAID 170LP, a low-profile PCI card. Pretty neat. AMI recently sold all of their RAID card business to LSI Logic, this making getting some of the AMI cards a bit difficult right now. Otherwise, I would also recommend the AMI Express 500. If you are looking for IDE, I have no comment there. # Jesse Molina lanner, Snow # Network Engineer Maximum Charisma Studios Inc. # [EMAIL PROTECTED] 1.303.432.0286 # end of sig -Original Message- From: Andrew Kaplan [mailto:[EMAIL PROTECTED] Sent: Monday, November 05, 2001 3:20 PM To: Debian-Isp Subject: hardware raid I'm looking for a good hardware raid 1 (mirroring) solution for Debian.

Re: Hardware RAID
I know its been some time since this post, im primarily responding for the archives, maybe someone will find the info usefulll.. i was looking for the exact same thing, an inexpensive hardware RAID controller. (something in the hundreds of dollars as apposed to the thousands). What i wfound was the AAA-13x card, its an adaptec hardware raid. and i looked on the hardware compatability list and it was listed etc. however... I got the card working, booted up off its cmos disk to flash the cards rom with the settings, and set it up as a RAID-1 ( i had 2 26 gig drives and just wanted mirroring). and the card was detected and all i had no problems as far as that was concerned and I even 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!

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.
