Connecting to iSCSI Host Servers
Choose the iSCSI connectivity option that best suits the front‐end redundancy requirements and network infrastructure.
Preparing Host Servers
Install the iSCSI host bus adapters (HBAs) or iSCSI network adapters, install the drivers, and make sure that the latest supported
firmware is installed.
• Contact your solution provider for a list of supported iSCSI HBAs.
• Refer to the Dell Storage Compatibility Matrix for a list of supported HBAs.
• 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 same server.
b. Install supported drivers for the HBAs or network adapters and make sure that the HBAs or network adapter have the latest
supported firmware.
c. 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.
d. 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:
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 or network 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 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.
