Attach iSCSI hosts to the storage system
Perform the following steps to attach iSCSI hosts to the storage system:
1. Ensure that all network adapters have the latest supported firmware and drivers as described on the Dell Support portal.
NOTE: The Dell EMC PowerVault ME4 Series storage system supports only software iSCSI adapters.
2. Use the iSCSI cabling diagrams to cable the host servers either by using switches or attaching them directly to the storage system
using one-to-one mode. Record the two different IP address ranges for each storage system controller. For example: 172.2.15.x,
172.3.20.x .
3. If the host servers are connected to the storage system by iSCSI switches, configure the switches to use two different IP address
ranges/subnets.
Configuring the switches with two different IP address ranges/subnets enables high availability.
Configure the VMware ESXi VMkernel
Perform the following steps to configure the VMware ESXi VMkernel:
1. From the VMWare VSphere web client, click Configure > Networking > Physical adapters.
2. Locate and document the device name for the NICs used for iSCSI traffic.
3. Click the VMkernel adapters, then click the plus (+) icon to create a VMkernel adapter.
4. On the Select Connection Type page, select VMkernel Network Adapter > Next.
5. On the Select Target Device page, select New standard switch > Next.
6. On the Create Standard Switch page, click the plus (+) icon, then select vmnic > OK to connect to the subnet defined in step 4 of
the “Attach hosts to the storage system” procedure.
7. Click Next.
8. Provide a network label, then update the port properties.
9. On the IPv4 settings page, select Static IP and assign an IP using your planning worksheet.
10. Click Next.
11. On the Ready to complete page, review the settings and then click Finish.
12. Repeat steps 1–11 for each NIC to use for iSCSI traffic.
NOTE:
If you are using jumbo frames, they must be enabled and configured on all devices in the data path, adapter
ports, switches, and storage system.
