How many clustered databases can you have on a server?
I was asked about a theoretical limitation on databases on a Domino cluster based on some (apparently) archived information suggesting a limitation of about 8,000. I found that in older releases, it was necessary to use the CLUSTER_DIRECTORY_MAX_POOLSIZE_MB notes.ini parameter to increase the default 16 MB memory pool for the cluster directory. This was changed in 7.0.3 and 8.0 to be dynamically sized up to 250 MB, theoretically allowing for about 125,000 databases. Additional memory pools like RTR_MAX_POOLSIZE_MB and DIRMAN_POOLSIZE_MB would also come into play, along with many other practical limitations.

Hi!
We have 30.000 clustered databases on one Domino 7.0.2 server pair,
no CLUSTER_DIRECTORY_MAX_POOLSIZE_MB setting and did not recognized
any limitation yet. Could you pleas tell us what we have to look
for?
Thanks

@1 Are you experiencing any issues with some databases not being cluster replicated?
