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).
