The 256 is per storage port, you only have one host connection per host per storage port so more like 256 hosts.
Also you can split hosts across node pairs, host1 on node 0+1, host2 on node 2+3 if lower IO.
Personally I consider the 256 limit as being a hard limit rather then a target to aim for in production, it might be fine in a test lab where non of the servers do anything but in real world I'd look more towards 64 or 128 depending on load.
Same here, i don't go by the maximum number of hosts I could connect, its all based on the bandwidth they consume. Also keep in mind to stay below the threshold needed for failover. if a port is 100% saturated and the peer port fails, it won't be able to accept the additional traffic needed.
