VMware vSphere FC best practices

  The following best practices are recommended:
  · To reduce broken links, insert several HBA cards in each server and use numerous storage array access paths.
  · Use load-balancing software, such as native ESXi Round Robin, or EMC PowerPath/Virtual Edition, to optimize path management between servers and storage.
  · Use ALUA-compliant storage arrays that are compatible with VMware’s VAAI APIs.
  · Use the same number of paths between all members of the cluster, and all host servers within a cluster should see the same volumes.
  · Comply with the connection compatibility matrix between the members of the ESXi cluster and storage.
  · Use the same speed of switches in all connections to avoid the creation of contention points in the SAN.
  · Check firmware levels on FC switches and HBAs, and follow instructions from the storage array manufacturer.
