Add an NVMe target (or SDT component) to
PowerFlex.
Steps
On the menu bar, click
Block > NVMe Targets.
Click
+ Add NVMe Target.
In the
Add NVMe Target dialog box, configure the following settings:
For
Target Name, enter a name for the NVMe target (or SDT component).
For
Protection Domain, select a protection domain.
Accept the default TCP ports, or modify them if necessary.
Storage Port listens for incoming connections from the MDM, and is only open on an IP address configured with the storage role. Default=12200
I/O Port listens for incoming connections for I/O, and is only open on an IP address configured with the host role. Default=4420 (which conforms to the NVMe over TCP standard)
Discovery Port listens for incoming discovery connections, and is only open on an IP address configured with the host role. Default=8009 (which conforms to the NVMe over TCP standard. Use zero to disable the discovery service.)
For
Target IPs, enter an IP address, and then select a role for the IP address from the
Target IPs Roles menu. Click Add Target IP, and repeat this step until all IP addresses are configured.
Click
Add.
Verify that the operation has finished and was successful, and click
Dismiss.
