DRBD Users, 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 ?
TIA, -JAC
