Data Center Bridging
« on: December 15, 2014, 09:58:33 AM »
Hi forum,

Is anyone have some good experience and/or documentation regarding DCB with Avaya switches ?

I'm currently asking a guy directly at Avaya, but I do want to see here on the forum if someone have some implementation of DCB.

We are looking to buy some VSP 7024XT and in the fact sheet it says they have support for DCB, but I need more specific information about the version of certain thing to make sure it will be fully compatible with our Equallogic SAN.

Because Dell have a "Dell Storage Compatibility Matrix" which they identify "compatible" switch with their Equallogic, which meen the others are "incompatible" as the like to say. But it's more "untested" :


The last model tested is the ERS 5510-48T... But they have plenty of Cisco / Brocade / Dell model tested and approved... In my opinion, it's way to push only certain brand... We are little worried to buy Avaya VSP 7024XT which we like a lot more, but being said that they are not compatible, when we'll call Dell for a problem not regarding the switches at all... They will have the easy answer : We do "not support" those switches.

The switch need to support at least these fonction :

◦Per Priority Flow Control (PFC) 
◦Enhanced Transmission Selection (ETS) 
◦Data Center Bridging Exchange (DCBx) 
◦iSCSI TLV (Enterprise iSCSI over DCB)

If there is no answer coming from someone in the forum, i'll keep my post updated when Avaya will give me the information.

DCB is supported on the VSP7k platform.
I have only done it with HP gear, but I would suggest that it also will work with Dell gear.

The best ressource is the Software-Defined SAN Solution Guide.
Hopefully it will answer most of your questions.


Itīs always the networks fault!
