That's a one node cluster. You can have as many realservers (in your case
sql1 and sql2) as you want, it still remains from a heartbeat point of view
a one-node (namely loadb1) cluster.
I want loadb1 to do loadbalancing the mysql load to two database
> servers without MASQ.
Okay, you want LVS-DR then, not LVS-NAT. Have you read the LVS-HOWTO on
LVS-DR?
One question is - it is possible topology?
Sure.

Wait. First of all, what did you *solve*? Second, you just said you didn't
want MASQ.

I suggest reading the HOWTO then. It's a very good 'education'. Start with
the mini-HOWTO and take the LVS-DR setup. Forget about heartbeat. Forget
about more nodes. Forget about databases. Forget about ldirectord. Just take
your loadb1, configure LVS-DR on it with ipvsadm. Take your sql1 and setup a
telnet server or whatever (ssh works too). Then get a connection from
client->loadb1->sql1 working. Once you get that working, set up ldirector so
it configures the LVS table for you.
Finally, you only need heartbeat if you plan on having more than 1
loadbalancer (director). Oh and read about the arp problem.
