Btier is not a cache but tiered storage that automatically moves frequently accessible data to fast(er) device.
wget http://sourceforge.net/projects/tier/files/STABLE_PRODUCTION/btier-1.3.11.tar.gz
tar -xvf btier-1.3.11.tar.gz -C /usr/src
dkms add -m btier/1.3.11
dkms build -m btier/1.3.11
dkms install -m btier/1.3.11
modprobe btier
#dkms remove -m btier/1.3.11 –all # You can remove if build was not successful
