Why each option
The NetApp CN1610 cluster interconnect switch supports a maximum of 12 cluster nodes when running ONTAP 8.2.
4 nodes is far below the CN1610's documented maximum capacity in ONTAP 8.2 - the switch was designed to support multi-node enterprise clusters.
8 nodes does not match the documented and validated maximum node count for the CN1610 switch in ONTAP 8.2.
The CN1610 is a 16-port 10GbE switch where each cluster node requires two dedicated interconnect ports, and in ONTAP 8.2 the validated maximum is 12 nodes - the remaining ports are reserved for inter-switch links in two-switch configurations and future capacity.
16 nodes exceeds the CN1610's supported limit in ONTAP 8.2 - port count constraints and inter-switch link requirements cap the maximum at 12 nodes.
24 nodes far exceeds the physical and validated capacity of the CN1610 in ONTAP 8.2 and would require a higher-density cluster interconnect platform.
