In rack mount chassis, do the cages that house the hard disks have the following feature?

Does these bays have a connector (+ cable) that is connected to the motherboard or RAID card to control the HDD LEDs in the bay? (sorry if this appears basic but I have no experience with such hardware)
They have sleds. You screw a std. drive into one, and shove it in - literally, that's all there is to it.
(b) The failed HDD can be swapped.
If they are in hotswap bays, yes. if they aren't, no.
Are the hot swap bays compatible with Linux mdadm RAID? i.e. Upon detection of disk failure, the respective HDD LED on the bay can be turned ON?
Everything understands hot swap bays these days, and certainly Linux, like every other version of Unix, does. Let's see, I have well over a hundred rackmounts in our server rooms and the data center, all have hot swap, and 90% are running CentOS (and a very few RHEL, and a couple of odd things, and there are the few WinDoze servers (they have hot swap, also). <snip>
The 2U system is for an appliance that I am building and it will be a commercial product. I plan to order the "integrated" system from "value add" SIs of Supremicro/Tyan (whover is able to satisfy the h/w spec.). My storage requirement is 2TB (4X1TB disks), a 6 disk bay should be sufficient (or whatever is the lowest denominator).
You absolutely do *NOT* want anything but hot swap. Take a look at the Dell R[468]10's. <snip> mark
