VMware vSphere FC best practices

2012-09-29 12:57 141 查看
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.
