Hi DRBD users,
How do you have set up your DRBD cluster? I can come up with the
following setups:
1:1
For each productive host there is one hot standby host. This means
double hardware cost.
n:1
There are multiple productive hosts for a single hot standby host. For
3:1 this only increases hardware cost by about 50% (you still need
diskspace for each productive system). When it comes to a failure, the
other productive hosts must not fail too until the failed host is back
up again and productive.
For the n:1 situation: Anybody here who utilizes such a setup? What kind
of disk system do you use? Thanks for sharing!
Michael
