For information, see Dell EMC Knowledge Article 000196316 (PowerStore: After increasing the MTU...). ● When using iSCSI software initiator with ESXi and PowerStore storage, it is recommended to use only lower case characters in the IQN to correctly present the PowerStore volumes to ESXi.

NVMe/TCP Configuration This section describes the recommended configuration that should be applied when attaching hosts to a PowerStore cluster using NVMe/TCP. NOTE: This section applies only to NVMe/TCP. If you are using any other protocol with ESX, see the relevant configuration section. Pre-Requisites The following pre-requisites should be met before attaching hosts to a PowerStore cluster using NVMe/TCP: ● Review NVMe over TCP (NVMe/TCP) SAN Guidelines before you proceed. ● See the E-Lab NVMe/TCP Host/Storage Interoperability Simple Support Matrix for supported NIC/HBA models and drivers with NVMe/TCP and known limits. ● Verify that all HBAs have supported driver, firmware, and BIOS versions. ● Follow the operating system recommendations for installation and setup of the appropriate NIC/iSCSI HBA for your host. ● It is recommended to install the latest driver version (patch), as described in the VMware support site for each specific NIC/iSCSI HBA. ● TCP ports 4420 and 8009 are open between each host interface and PowerStore subsystem port. These ports should be open on the interfaces where NVMe/TCP is running. ● Review the VMware vSphere Storage document for the vSphere version running on the ESXi hosts, a requirement list, limitations, and other configuration considerations. For example, for vSphere 7.0u3, see VMware vSpere Storage. Setting the ESXi Host NVMe Qualified Name Prerequisites You can configure the host NVMe Qualified Name (NQN) using either Hostname or UUID. For visibility and simplicity, it is recommended to use Hostname. Steps 1. Connect to the ESXi host as root. 2. Run the following esxcli command for the Host NQN to be based on the hostname and verify that the setting is changed. $ esxcli system module parameters set -m vmknvme -p vmknvme_hostnqn_format=1 Host Configuration for VMware vSphere ESXi 33

NVMe/TCP Configuration
This section describes the recommended configuration that should be applied when attaching hosts to a PowerStore cluster
using NVMe/TCP.
NOTE:
This section applies only to NVMe/TCP. If you are using any other protocol with ESX, see the relevant configuration
section.
Pre-Requisites
The following pre-requisites should be met before attaching hosts to a PowerStore cluster using NVMe/TCP:
●
Review
NVMe over TCP (NVMe/TCP) SAN Guidelines
before you proceed.
●
See the
E-Lab NVMe/TCP Host/Storage Interoperability Simple Support Matrix
for supported NIC/HBA models and drivers
with NVMe/TCP and known limits.
●
Verify that all HBAs have supported driver, firmware, and BIOS versions.
●
Follow the operating system recommendations for installation and setup of the appropriate NIC/iSCSI HBA for your host.
●
It is recommended to install the latest driver version (patch), as described in the VMware support site for each specific
NIC/iSCSI HBA.
●
TCP ports 4420 and 8009 are open between each host interface and PowerStore subsystem port. These ports should be
open on the interfaces where NVMe/TCP is running.
●

VMware vSphere Storage
document for the vSphere version running on the ESXi hosts, a requirement list,
limitations, and other configuration considerations. For example, for vSphere 7.0u3, see
