Small companies with really tight purse strings may seem fine this week, then suddenly fold next week, everyone loses their jobs in the process. >> Get yourself an Adaptec 8 port PCIe x8 RAID card kit for $250: >> http://www.newegg.com/Product/Product.aspx?Item=N82E16816103231 > I'm gonna try to persuade my boss to buy one and in case he agrees and It's the least expensive real RAID card w/8 ports on the market, and a high quality one at that.

That's hard to believe given the worldwide penetration Adaptec has, and the fact UPS/FedEx ship worldwide. What country are you in? > What about something like this: > http://ark.intel.com/products/35340/Intel-RAID-Controller-SASMF8I This Intel HBA with software assisted RAID is not a real RAID card. And it uses the LSI1068 chip so it probably doesn't support 3TB drives. In fact it does not, only 2TB: http://www.intel.com/support/motherboards/server/sb/CS-032920.htm > If not, how to find appropriate one? One with 8 supported devices, > hardware RAID10? What else to look for? There are many cards with the features you need. I simply mentioned the least expensive one. Surely there is an international distributor in your region that carries it. If you're in Antarctica and you're limiting yourself to local suppliers, you're out of luck. Again, if you tell us where you are it would make assisting you easier. > There is something that is not clear to me. You recommended hardware > RAID as superior solution.

This depends entirely on the system BIOS, its limitations, and how you have device boot order configured. For it to work seamlessly you must manually configure it that way. And you must make sure any/every time you run lilo or grub that it targets both drives in the mirror pair, assuming you've installed lilo/grub in the MBR. Using a hardware RAID controller avoids all the nonsense above. You simply tell the system BIOS to boot from "SCSI" or "external device", whatever the manual calls it. > In case I don't get that card, > should I remove /boot from RAID1? Post the output of ~$ cat /proc/mdstat I was under the impression you didn't have this system built and running yet. Apparently you do. Are the 4x 3TB drives the only drives in this system? -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
