PowerStore 500T and NVMe/TCP with S5212F switches arquitecture
Hi.
I have a question about the design of a NVMe/TCP architecture for a PowerStore 500T with Firmware version 4.1.0. and a 4-port 25Gbe card.
I have experience with iSCSI on 1000T enclosures but this one is looking different to me .
I am reading the Networking guide documentation and I am getting more questions than clarifications.
For the sake of simplicity, I'll expose the configuration that I have done so far to see if it is correct and if I have interpreted the manuals correctly.
The switches are two Dell S5212F with VLT configured.
In the PowerStore:
Node A - P0 - SW1 - P1
Node B - P1 - SW1 - P2
Node A - P1 - SW2 - P1
Node B - P0 - SW2 - P2
With this configuration I have seen that for Node A and Node B I have created 2 Bond 0.
I configure a Storage Network where I indicate the VLAN 12 and 3 IPs, 10.10.12.33 as Discovery and 10.10.12.34-35 as the two IPs to assign, and these are associated to the Bond 0 where each of them acquires an IP.
In the Switch, 2 LACP aggregates have been configured, one for the ports of node A and one for the ports of Node B.
Is all this correct? I have in my head the concept of iSCSI, without LACPs, with one IP per port and I do not see it clear in the documentation.
Thank you very much in advance.

Hello sgiwt,
Which guide are you following to configure your Powerstore system? If you are using the PowerStore T and Q Networking Guide for Storage Services that is the guide you will want to follow. As a base configuration you will want to make sure that each powerstore controller has an active connection to each switch.
