Try `cat /dev/sda >/dev/zero` on the remote while running `dstat -tma`
in another terminal.
Also try with smaller files.

I tested it with a smaller file (2G) and the buffered memory was
returned as soon as the cat command finished. Then I tired with
/dev/sda (60G) and it went up until about 50MB free were reported and
stayed there (buff was 6.5GB) until I issued `echo 3
>/proc/sys/vm/drop_caches` then dropped to 2M.
