How do I set up a raid 0+1 with a pci card?

How do I set up a raid 0+1 with one drive to the motherboard and the other two to the raid card? Set up in bios but it keeps telling me to copy the sata directory to the floppy disc but I can't find it anywhere and isn't in the software that came with the card. The software is no help whatsoever. when I hook up the drives to the card they won't raid but will if connected to the motherboard. I haven't loaded the drivers for it because it says to copy that info to a floppy. It then tells me to verify the driver was loaded after loading the info to the floppy disc.  I am new to this and need some guidance.

Your not going to be able to set it up that way, first problem is raid 0+1 requires 4 hdds, and 2nd problem is of you want all the drives in the same array they will need to be attached to the same raid controller, either all 4 on the motherboard or all 4 to the pci raid controller. To hlp you get it setup on the pci raid controller I need to know first, What model is the pci raid controller? What model are the hdds your trying to create the array with?

I was told that I could have my OS on one drive connected to the motherboard and two other drives to the controller card. The pci raid controller is SATA 150 Raid controller card: MERCURY
Dell dimension 5100, 3.2 pentium h, 1 GB. I have three SATA drives all 160GB(2 seagate, 1 western digital) All exactly the same except the brand. What would be the best thing for me to do. I video edit a lot and definately need the performance but also need a back up in case something goes bad. (which will happen with a DELL computer) Thank you!!!

You're really going to need 5 drives: an OS drive to boot up with (this can be a small 40GB drive, but perhaps high performance), and 4 drives arranged in a RAID 0+1 array on the PCI RAID controller to provide both speed and backup.  Does your card support RAID 0+1?

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

YEs, it supports 0+1. I don't think my dell can handle 5 drives. There are two sata connections on the motherboard. There are two sata connections on the controller card. Where would I hook up so many drives?

If the card only has 2 sata ports it most likely only supports raid 0 and 1, all the mercury sata raid controllers i could find that only had 2 ports only supported raid 0 and 1, none supported 0+1 unless it had 4 ports. also you may have a problem fitting 4 drives into the 5100 it was only designed to hold 2 hdds.

The mercury box states states
1. provides 2 sata 150 channels
2. raid level 0
3. raid lever 1
4. raid level 0+1
5. supports 150 rates of up to 1.5 gbps
6. silicon image chipset
so, I would need 4 ports on the card? Why would they say 0+1 if it only has two ports? I couldn't raid two drives from my motherboard. I had to use the card but they aren't connected to the card but the motherboard which seems odd to me. What can I do with what I have? Can I do anything with 3 drives? This tech guy told me to run my os from the motherboard and raid the other two from the card. He said that was 0+1. I guess I can't do that from what I am hearing. Do you know a good site that gives exact specifics on how to do this? Thanks!!!

Sounds like that tech guy wasnt quite sure what he was doing, you can plug 1 drive (non raid) into the motherboard and install your os on it, and have 2 hdds plugged into the raid controller and create a raid 1 mirror(redundancy) or 0 striping(performance). I think the way the controller supports a raid 0+1 is it creates 2 logical disks on each hdd (for a total of 4 logical drives) then stripes the 2 logical disks on each hdd (creating 2 logical raid 0 drives) then mirrors the 2 logical drives creating the raid 0+1, and your not going to get any performance increase this way like you would with an actual 4 disk raid 0+1 setup. So what your probaly going to want to do is  attach the western digital hdd to the motherboard for the os, and attach the 2 seagates drives to to raid controller and create either a raid 1 or 0.

Would it be better to raid 1 or o? I guess I need bigger drives? The OS drive to the motherboard what about the jumper? And the two to the raid card, jumpers? Not exactly sure how they should be set. Would the OS be the master? do the two seagates need to be completely empty? Do I use the bios to configure the raid or windows? The directions that came with the card absolutely suck!!!!!!!!!

The directions tell me to make a floppy and copy the sata directory. Do you know where I might find that because for the life of me I can't.

sata hdds dont require jumpers, the only exception i have heard of is certain sata 2 hdds being hooked to a sata 1 controller. To setup the raid on the controller you will need to go into the controller bios, not sure what keys to press on a mecury card not familiar with them but it should say in the manual for the card (i cant find a website for manufacture of the card is mercury the model or the manufacture?). Now to install xp it should recognize the hdd plugged into the motherboard (the hdds attached to the pci raid controller will require a driver be installed for the card before they are recognized but you can do that after the os installation). If it doesnt you may be using an older version of xp (pre sp1 didnt have driver for ahci sata controllers), if so you will need to boot into the bios and change the sata operation to combination then xp setup should recognize the hdd, once you get xp upto date you should be able to change it back(ahci will offer better performance). The ? if you want raid 0 or 1 depends on what you want. Raid 0 is performace raid if you have 2 160gb hdds it will create 320gb array and offer better performance than a single hdd but has no redundancy if 1 hdd fails the data is lost. Raid 1 is a mirror, so 2 160gb hdds would create 1 160gb array and if 1 hdds fails the data will be fine and this performs the same as a single hdd.

If I do a raid 0 can I back up the info to a external drive in case of a hdd failure or use power quest drive image?

jamietonerCommented:
yes, the data on the array could be backed up to an external drive

So, I hook up the OS drive to the motherboard and the other two to the controller card? When I go into the bios should I use the auto configuration? There is a manual config but it's asking for things that I don't know anything about. The manual for the card is a tiny little ting with 8 pages and doesn't help at all.
I believe the manufacturer is Manhatten for the mercury card.
Can I already have the OS on the drive? Do the other drives need to be completely empty?  I have xp media center edition 2005 in case you needed to know that.
I am going to raid 0 so I can have better performance and just back it up with powerquest to an external just in case.
one drive is empty but the other two are partioned. Do I need to copy that drive and just reformat it? The one with the os has three partions on it. What do I do about that one?

if the drives (that are going to be in the raid) arent empty they will be when you put them in the raid because the data on them will be erased. The os disk wont be affected since its attached to a different controller. i looked at the manufactures site and they dont have an online manual or any type of support documentation, but with most auto configs you should be able to choose raid 0 and it will set it up, once the raid is created install the driver for the controller and then go into disk managment and you will be able to partiotion and format the new disk created by the raid 0.
