Dell Storage Center SCv2000 and SCv2020 Storage System Deployment Guide

Install the iSCSI host bus adapters (HBAs) or iSCSI network adapters, install the drivers, and make sure that the latest supported firmware is installed.

• If the host server is a Windows or Linux host:
  1. 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 same server.
  2. Install supported drivers for the HBAs or network adapters and make sure that the HBAs or network adapter have the latest supported firmware.
  3. Use the host operating system to assign IP addresses for each iSCSI port. The IP addresses must match the subnets for each fault domain.
     • CAUTION: Correctly assign IP addresses to the HBAs or network adapters. Assigning IP addresses to the wrong ports can cause connectivity issues.
     • NOTE: If using jumbo frames, they must be enabled and configured on all devices in the data path, adapter ports, switches, and storage system.
  4. Use the iSCSI cabling diagrams to cable the host servers to the switches. Connecting host servers directly to the storage system without using Ethernet switches is not supported.
• If the host server is a vSphere host:
  1. Install the iSCSI HBAs or network adapters dedicated for iSCSI traffic in the host servers.
  2. Install supported drivers for the HBAs or network adapters and make sure that the HBAs or network adapter have the latest supported firmware.
  3. If the host uses network adapters for iSCSI traffic, create a VMkernel port for each network adapter (1 VMkernel per vSwitch).
  4. Use the host operating system to assign IP addresses for each iSCSI port. The IP addresses must match the subnets for each fault domain.
     • CAUTION: Correctly assign IP addresses to the HBAs or network adapters. Assigning IP addresses to the wrong ports can cause connectivity issues.
     • NOTE: If using jumbo frames, they must be enabled and configured on all devices in the data path, adapter ports, switches, and storage system.
  5. If the host uses network adapters for iSCSI traffic, add the VMkernel ports to the iSCSI software initiator.
  6. Use the iSCSI cabling diagrams to cable the host servers to the switches. Connecting host servers directly to the storage system without using Ethernet switches is not supported.
