Although i am sure Corona688s suggestion is working fine for reasons of maintainability and understandability my suggestion is to use arrays for this kind of data. If the number of paramter sets to cycle through increases it is easier to extend this way. Something like this:

Code:
BASE=/opt/SP/
server[1]="server1" ;    user[1]="user1"  ;     dom[1]="dom1"
server[2]="server2" ;    user[2]="user2"  ;     dom[2]="dom2"
server[3]="server3" ;    user[3]="user3"  ;     dom[3]="dom3"

(( i = 1 ))
while [ $i -le ${#server[@]} ] ; do
        ssh -t "${user[$i]}@${server[$i]}" "cd $BASE/${dom[$i]} ; exec bash"
        (( i += 1 ))
done

I hope this helps.
