What is the maximum number of NFS server threads/clients
What is the maximum number of NFS server threads? NFS clients?
For ZFS Storage ZS5-2 , latest firmware...
What is the cost of a really high number, say 10,000?
What is the impact to CPU, memory and failover times? Is the limit per head or per cluster?
The NFS clients can be characterized as linux, very numerous but not very busy. The share must be mounted at all times.
There is no file contention between clients. All accessing the same share or a very few shares in unique directories per client.
Total load is reasonable, mostly writes.
