Does Linux support Intel Smart Response Technology?

I know this is not the correct place to ask, but I hope someone here will
know.

Does Linux support the Intel Smart Response Technology?

I am building a new computer and will have two 2TB disks and a 64 or 120 GB
SSD.  I am hoping to use the SSD cache feature.  I think I would configure a
bios RAID with 1 disk and the SSD as a cache, then use Linux to mirror that
with the second 2TB disk using the write mostly feature of MD.  But would it
be better to create a bios RAID1 with both disks and the ssd cache?

If I can't use that feature, does anyone have any tips on using two 2TB
disks and 1 SSD?  The best I can figure is to create a 3 way mirror using
all disks and set the hard disks to write mostly, and putting the OS and
/home on the 3 way mirror(s) then a 2 way mirror with the remaining space
for non-OS stuff (home movies, pictures, iso, whatever).

Thanks for any help,
Guy

Why not start with a brief summary of WTF is "Intel Smart Response Technology".

If you are looking to use SSD as a cache to HDDs, check out bcache

No, it does not. Server versions of IMSM do not support it. Client does: there is windows version only.
