Dell EMC PowerVault ME4 Series and Citrix XenServer | H18237
4.2 Multipath with dual subnets
Using XenServer Open-iSCSI multipathing with dual subnets to properly connect to Dell EMC
PowerVault ME4 Series storage requires the following:
• XenServer 7.6 or later
• iSCSI using two unique, dedicated storage NICs and subnets. The two subnets should be different
from the XenServer management network to comply with Citrix best practices
• Multipathing enabled on all XenServer hosts in the pool
• iSCSI target IP addresses for the Dell EMC PowerVault ME4 Series storage Front End control
ports. For the example included in this document, the iSCSI FE control ports on Dell EMC
PowerVault ME4 Series storage are assigned IP addresses 10.10.10.100/24 and
10.10.11.100/24
In this configuration, the Dell EMC PowerVault ME4 Series storage is configured with the iSCSI Front End ports
on two separate subnets, different from the management interface. The Dell EMC PowerVault ME4 Series
storage is configured with two control ports, one on each subnet. Multipathing is controlled through MPIO.
