RAID 0

[Dagk]

Is it possible to set up software RAID LEVEL 0 DISK STRIPING across 4 disks in NT 4.0 SP 6a without a hardware RAID card? Thanks in advance for any advice.

According to NT Disk Administrator, you can set up a Raid 0 set on any number of disks from 2 - 32. You specify all the disks and a size, and Disk Administrator creates equally sized unformatted partitions across all the reqiested disks. The following Help extract details the procedure. This method does not require Hardware Raid support.

"Select two or more areas of free space (on from 2 to 32 hard disks) by selecting the first area of free space on the first disk, and then pressing CTRL and clicking an additional area on each of the other hard disks."

Yes you can... using windows NT 4 Disk administrator. If you have not used Disk administrator, feel free to drop me an email: heptabyte@netscape.net.

Furher to previous post, please remember that Raid-0 provides performance, but no resilience. A logical disk made up of 4 physical disks in a Raid-0 Stripe Set is 4 time more likely to fail then a single disk, so dont use for system partition, and ensure regular backup.

If you are wanting to do this for redundancy or fault tolerance then it is not going to work. You can do it but why would you want to? I think that the performance gain in throughput would be offset by the added load on the system resources since NT is going to have to manage the I/O. It is better in the long (and short for that matter) run to use a seperate controller and let NT just write and read to one location. The Controllers are designed to take that load off of the OS. Let them.
