Dell MD Storage Array vCenter Plug-in | 24

ESX Host SAN Configuration

This vCenter Plug-in allows for an ESX host to be automatically configured to use a Dell MD Storage Array

by detecting the installed Host Bus Adapters (HBAs) within the ESX host and configuring new hosts on the

storage array with the Worldwide Names (WWNs) of the HBAs from the ESX host. The default ESX

multipathing mode for Dell MD Storage Arrays is Most Recently Used (MRU). To ensure optimum

performance for the ESX host with more than two HBAs, the ESX host should be configured to use the storage

array in pairs of HBAs. This method allows for the maximum I/O throughput from the ESX host to the storage

array. Using this method requires proper SAN configuration and balancing of LUNs between hosts/host groups.

Figure 20

shows a properly configured two HBA port ESX host SAN configuration utilizing two fabric

switches and a dual controller storage array.
