He probably is referring to the userland tools for managing the controllers, which are useless on most distros. Which makes the hardware much less valuable, since you have to down the system and get into the adaptor's BIOS just to look at it, let alone adjust it. See for example *any* HP storage or system-management product. The tools will not even load -- they depend on versions of libstdc++ that do not and will never exist in most distros. The megaraid (and cciss) drivers *have* been in-kernel for a long time now and *do* work well -- once you get the adaptor set up from BIOS. As long as you're happy to set-and-forget, they are good choices. --=20 Mark H.
