[DRBD-user] Practical limit on number of paired devices on 2 hosts

Looking for some advise on performance implications as the number of drbd
devices on a host increases. What is the trade off between:-
1. Having a large number of small drbd devices (100s GB) v/s a small number
of large devices (0.5 to 1 TB)
2. Is there a limit on the number of drbd devices on a host - can it be in
the 200-300 range ? or more..
3. Is there an increased overhead and the number of devices increases - or
is it largely a function of the rate of data change ?
4. Does it matter if 100s of drbds are paired between 2 hosts ?
