Storage path selection plugins
Multipathing allows more than one physical path to be used to transfer data between the ESXi hosts and the storage array. In the event of a failure in a storage path, the host or hosts can switch to another available path. Multipathing also provides load balancing by distributing the storage IO across multiple physical paths.
How to do it...
To determine the multipathing policy, we perform the following steps:
Identify the different native multipathing policies available and the capabilities of each policy.
Select a multipathing policy based on the number of paths and the array type used.
Change the default multipathing policy using the
esxclicommand.Configure the multipathing policy on the storage devices presented to the ESXi host.
How it works...
The VMware Native Multipathing Plugin (NMP) supports storage arrays listed on the VMware Hardware Compatibility List (HCL). NMP provides path selection based on the array type by associating a set of physical paths with...
