VMware vSphere settings
17 Dell EMC PowerVault ME4 Series and VMware vSphere | 3922-BP-VM
6 VMware vSphere settings
The following configuration settings are recommended for the VMware ESXi hosts.
6.1 Recommended iSCSI vSwitch configuration
To configure the VMware iSCSI software initiator for multipathing, see the VMware articles, Configuring
Software iSCSI Adapter and Setting Up iSCSI Network located at VMware Docs.
For users with previous experience configuring iSCSI for multipathing, here are a few key points for a
successful configuration:
• Create two VMkernel adaptors, one for each SAN fabric.
• Make sure each VMkernel adaptor is on its own vSwitch with a single vmnic (physical NIC adaptor).
• Remember if Jumbo frames is used, it must be enabled on both the VMkernel adaptors and the
vSwitches.
• Enable the software iSCSI initiator.
• Add an IP address from an iSCSI port on controller A to the software iSCSI imitator under dynamic
discovery.
• Add a second IP address from an iSCSI port on controller B to the software iSCSI initiator under
dynamic discovery.
• Ensure that each IP address used in the prior steps represents each of the subnets used in the SAN
fabric.
• Rescan the iSCSI software adapter.
