..and this also means they have the downside that you have problems
monitoring the disk healthstatus from Linux.  The vendor wants to
settle on your system with his non open code (and maybe even kernel
modules) to inform on disk problems.

For most hardware raids small, mostly open userland tools exist to do that.
Never understood why almost noone transports that information directly
via driver and informs linux on problems.
