VMware LACP Disadvantages

Today, our experts are going to take us through some of the disadvantages of configuring LACP.

• Configuring LACP can be more complex than setting up a single network link. It requires coordination between the VMware environment and the network switches for proper configuration on both sides. Misconfigurations can lead to connectivity issues.
• Furthermore, the proper functioning of LACP relies on network switch support. Not all switches may support LACP. Additionally, there is a difference in how LACP is implemented across different switch vendors.
• LACP provides load balancing based on characteristics like source and destination MAC addresses or IP addresses. Sometimes, this may lead to suboptimal load balancing for individual virtual machines.
• The effectiveness of load balancing depends on the algorithm used and the traffic patterns. In certain situations, the load balancing algorithm may not evenly distribute traffic across all aggregated links, potentially leading to suboptimal utilization of available bandwidth.
• The negotiation and management of LACP connections lead to additional latency in some cases. This latency is more noticeable in environments with strict latency requirements.
• Workloads with low network utilization or those that don’t generate a high volume of traffic will not have a huge improvement in performance by using LACP.
• LACP configurations have to be consistent across all participating devices, including ESXi hosts and network switches. Misconfigurations can lead to connectivity issues.
• In environments with dynamic changes, there might be challenges in maintaining consistent LACP configurations.
• Applications that rely on a single network connection or stream will not benefit a lot from LACP.
