Converged Ethernet Adapter X520-DA2 support for active direct attached cables

Jump to solution

Hello,

We want to update our network infrastructure to 10GB/s. Therefor we have to buy new networkcards for our existing servers.

The distance between server and networkswitch is more than 7meter. So we want to use 10m active direct attached cables.

On the support site of the X520 (https://www.intel.com/content/www/us/en/support/articles/000005528/network-and-i-o/ethernet-products... SFP+ Modules, SFP Modules, and Cables Compatible with Intel® Ethernet... ) we saw that active cables are supported:

Are active and passive direct attach cables both supported on the Intel® Ethernet Converged Network Adapter X520 Series?

  • Both passive and active cables are supported.
  • Active cables require Intel® Network Connections software version 15.3 or later.

But when I looked closer to the readme of the driver it say´s active cables are not supportetd. (https://downloadmirror.intel.com/14687/eng/readme.txt https://downloadmirror.intel.com/14687/eng/readme.txt )

Active direct attach cables are not supported.

What is the truth now? Does any one has experience with X520 and active direct attached cables?

Regards,

manuel

Hi Manuel1.

 

 

Thank you for posting in Wired Communities. If you are referring to this statement

 

"82598-based adapters support all passive direct attach cables that comply with

 

SFF-8431 v4.1 and SFF-8472 v10.4 specifications. Active direct attach cables

 

are not supported." in the README file. This is referring to the network adapter that used 82598 ethernet controller not X520 series network adapter.

 

 

X520 series network adapter used 82599 ethernet controller,here is the product brief for your reference:

 

https://www.intel.com/content/www/us/en/ethernet-products/converged-network-adapters/ethernet-x520-s...

 

 

You can just refer to this website about the cable for X520 series network adapter

 

https://www.intel.com/content/www/us/en/support/articles/000005528/network-and-i-o/ethernet-products...

 

 

In case you are interested to purchase, you may try contacting our Intel authorized resellers which can be located at http://locate.intel.com,

 

 

Hope the above information help. Thank you.

 

 

Regards,
