I need to sum from ssd20 and ssd30 of second block in new line and sum from sd1 to sd8 in another line.

This acts exactly as you have specified:
Code:
awk     'BEGIN {f[1,1]="ONE"; f[2,1]="TWO"; OFS="\t"}
        /^sd[1-8]/       {for (i=2;i<NF;i++) f[1,i]+=$i}
        /^ssd[23][0-9]/  {for (i=2;i<NF;i++) f[2,i]+=$i}
        $1=$1
        END {for (i=1;i<=2;i++) {printf "%s ",f[i,1]; for (j=2;j<=10;j++) printf "\t%3.1f", f[i,j]; print ""}}
        '

OK, use "tail" and exclude first block and sum the specific column.
thanks
