• If the host server is a Windows or Linux host:a. Install the iSCSI HBAs or network adapters dedicated for iSCSI traffic in the host servers.NOTE: Do not install iSCSI HBAs or network adapters from different vendors in the sameserver.b. Install supported drivers for the HBAs or network adapters and make sure that the HBAs ornetwork adapter have the latest supported firmware.c. Use the host operating system to assign IP addresses for each iSCSI port. The IP addresses mustmatch the subnets for each fault domain.CAUTION: Correctly assign IP addresses to the HBAs or network adapters. Assigning IPaddresses to the wrong ports can cause connectivity issues.NOTE: If using jumbo frames, they must be enabled and configured on all devices in the datapath, adapter ports, switches, and storage system.d. Use the iSCSI cabling diagrams to cable the host servers to the switches. Connecting host serversdirectly to the storage system without using Ethernet switches is not supported.• If the host server is a vSphere host:a. Install the iSCSI HBAs or network adapters dedicated for iSCSI traffic in the host servers.b. Install supported drivers for the HBAs or network adapters and make sure that the HBAs ornetwork adapter have the latest supported firmware.c. If the host uses network adapters for iSCSI traffic, create a VMkernel port for each network adapter(1 VMkernel per vSwitch).d. Use the host operating system to assign IP addresses for each iSCSI port. The IP addresses mustmatch the subnets for each fault domain.CAUTION: Correctly assign IP addresses to the HBAs or network adapters. Assigning IPaddresses to the wrong ports can cause connectivity issues.NOTE: If using jumbo frames, they must be enabled and configured on all devices in the datapath, adapter ports, switches, and storage system.e. If the host uses network adapters for iSCSI traffic, add the VMkernel ports to the iSCSI softwareinitiator.f. Use the iSCSI cabling diagrams to cable the host servers to the switches. Connecting host serversdirectly to the storage system without using Ethernet switches is not supported.Virtual Port Mode - Two iSCSI Networks with Dual 10 GbE 2–Port Storage ControllersUse two iSCSI networks with virtual port mode to prevent an unavailable port, switch, or storagecontroller from causing a loss of connectivity between the host servers and a storage system with dual 10GbE 2-port storage controllers.About this taskThis configuration includes two fault domains, two iSCSI networks, and two Ethernet switches. Thestorage controllers connect to each Ethernet switch using one iSCSI connection.• If a physical port or Ethernet switch becomes unavailable, the storage system is accessed from theswitch in the other fault domain.• If a storage controller becomes unavailable, the virtual ports on the offline storage controller move tothe physical ports on the other storage controller.Steps1. Connect each server to both iSCSI networks.2. Connect fault domain 1 (shown in orange) to iSCSI network 1.• Storage controller 1: port 1 to Ethernet switch 1Connect the Front-End Cabling 67
