You can prevent performance issues for mirrored workloads in a MetroCluster configuration by ensuring that the MetroCluster configuration is set up correctly. You can also improve workload performance by changing the configuration or upgrading software or hardware components.
The MetroCluster Installation and Configuration Guide provides instructions for setting up the clusters in the MetroCluster configuration, including the Fibre Channel (FC) switches, cables, and inter-switch links (ISLs). It also helps you configure the MetroCluster software so that the local and remote clusters can communicate with mirror volume data.
For information about replacing or upgrading MetroCluster components, see the MetroCluster Service Guide.
