So these cards are just plug n play? Just plug them in, no software or drivers required, all mirroring is managed by firmware built into the card RAID card itself?Drivers are required for all storage adapters(RAID or not). 3Ware handles raid in hardware, not in software, it has a bios which you'd typically use to configure the array, you can boot off of the array, etc. 3Ware also offers a management tool for linux (CLI and/or web based) which allows for monitoring, and controlling the adapter's configuration settings. 3Ware has had their linux drivers in the kernel for at least... 8 years now? maybe longer. So any linux distro should have no trouble detecting the card. The latest 9650 cards are pretty new and use a new driver, which may or may not be supported, CentOS 5.1 should work with it fine though(support for CentOS 4 was added almost a year ago, I think with v4.5) They also support hot swap, provided the interface to the disk supports it(typically a hot swap backplane).Great thanks for that info Nate, I just checked out their web site, looks like the 9500S-4LP would suit my needs for a desktop machine.I've been leary about desktop RAID cards because a few years ago, I bought an adaptec 1210SA RAID card which supposedly does RAID 1 I never could get the darn thing to work in my old windows machine and years later found out it is really a fake raid card. It's been collecting dust ever since may as well throw it out. The drivers it required never worked with W2K. But the Centos server I use has adaptec SCSI RAID controller in it, I guess on the high end for SCSI RAID, adaptec is known for good raid cards, but the one I bought sure did nothing for me for my desktop. _________________________________________________________________
Adaptec makes both true HW raid and re-sells fakeraid cards. I guess they wanted a piece of both pies. But 3ware only makes HW raid cards AFAIK.
