A700 40g Breakout to 4x10Gb Ontap Config Question

[coreywanless]

I'm setting up our A700, and need to figure out how to convert e4e 40g to the e4e-h 10g ports. I have the breakout cabled up between the A700 and the end network switches. Where is the magic setting to make this happen?

Hey Corey,

You can convert the ports from 40 GbE to 10 GbE in maintenance mode. The command is

*> nicadmin convert –m [ 40G | 10G ] [ port ]

So if your 40g card is in slot 4, run

*> nicadmin convert -m 10G e4e

Converting e4e 40G port to four 10G ports

Halt the system, install/change the cable, and then reboot for conversion to take effect

I hope this helps! Let us know if this works for you.

Best regards,

Dirk

That was it. Thanks for the quick feedback.

Can you convert a single port to 4x10 10GBE and leave the other as a 40GBE ISL port?

If I understand you, yes, we have that configuration:

e4a Cluster Cluster up 9000 auto/40000 healthy false
e4e Default - up 9000 auto/10000 healthy false
e4f Default - up 9000 auto/10000 healthy false
e4g Default - down 1500 auto/10 - false
e4h Default - down 1500 auto/10 - false

e4a is the 40GB connection back to Cluster Switches

e4e and e4f (two of the 40g to 10g split are ran to our network switches) 

e4g and e4h are just hanging there on the other end. (Messy, but it is what it is)

If you are talking about the configuration on the other end (Where the 10g splitter connects into)  You will need to create a ifgrp on the Netapp side, and a port-channel side to bond them all together.

Hi,

Yes, that was the question. I should have provided more info but your answer is perfect despite my incomplete question.

Thanks

to follow up this thread, if I have two 40GbE ports, one is in slot 4, and the other is on onboard. If I want to setup 4x10GbE, should I just use all 4 split 10GbE from a single 40GbE port, or 2 x 10GbE from each 40GbE port should one of 40GbE port get failed, then the other 2x10GbE from the other 40GbE port would be still alive? I don't know enough about 40GbE port, could entire port go down at all?
