Caveats

• Only two health-check mechanisms (ICMP ping and TCP socket open)
• No higher-layer persistence mechanisms (Sticky IP only)
• No “sorry-server” mechanism if all servers in group are not responding
• No “round robin with persistence” mechanism
• No “weighted round robin” mechanism
• No method for detecting if resource is strained

While there is no limit to the number of internal resources that the SonicWall network security appliance can load-balance to and there is no limit to the number of hosts it can monitor, abnormally large load-balancing groups (25+ resources) might impact performance.
