If your controller includes a connection for NVMe over
RoCE (RDMA over Converged Ethernet), you can configure the NVMe port
settings from the Hardware page.
Before
you begin
Your controller must
include an NVMe over RoCE host port; otherwise, the NVMe over RoCE
settings are not available in System Manager.
You must know the IP
address of the host connection.
Select Hardware .
If the graphic shows the
drives, click Show back of shelf .
The graphic changes to show the controllers instead of
the drives.
Click the controller
with the NVMe over RoCE port you want to configure.
The controller's context menu appears.
Select Configure NVMe over RoCE ports.
The Configure NVMe over RoCE Ports dialog box opens.
In the drop-down
list, select the HIC port you want to configure.
Click Next.
To see all port settings, click the Show more port
settings link on the right of the dialog box.
Table 1. Field Details
Port Setting
Description
Configured ethernet port speed
Select the speed that matches the speed capability
of the SFP on the port.
Enable IPv4 / Enable IPv6
Select one or both options to enable support
for IPv4 and IPv6 networks.
Note: If you want to disable
port access, deselect both check boxes.
MTU size
(Available by clicking Show more port settings.)
If necessary, enter a new size in bytes
for the Maximum Transmission Unit (MTU).
The default Maximum
Transmission Unit (MTU) size is 1500 bytes per frame. NVMe over RoCE
has a maximum MTU of 4200. Any MTU size over that provides no benefit.
If you selected Enable IPv4, a
dialog box opens for selecting IPv4 settings after you click Next. If you selected Enable IPv6, a dialog box opens for selecting IPv6 settings after you click Next. If you selected both options, the dialog box for
IPv4 settings opens first, and then after you click Next, the dialog box for IPv6 settings opens.
Configure the
IPv4 and/or IPv6 settings, either automatically or manually.
