Actually "sa1" binary is part os "sar" toolkit (sysstat package). It
gathers system performance statistics and saves them to binary files
/var/log/sa<day number>.
Another binary from sar toolkit "sa2" which is run once per day
generates (based on /var/log/sa<day number> file) daily system
performance report which is then saved in  /var/log/sa/sar<day number>
file.

They're not neccessary for normal system operation and can be disabled
(whole sysstat package can be removed) but given the fact that sa1 and
sa2 programs are not resource consuming and the fact that sar reports
can be quite useful (i suggest storing them) - i would suggest not to
disable them.
