I am listening training FAS3200 Series Troubleshooting and slide 15 of module 1 has quite interesting statement:
the switch and cable must come from the same vendor
Is it really hard requirement? Is it specified anywhere else? Ot is it just my English (I interpret "must" as hard requirement; while slide itself is titled "Best practices", so IMHO "should" would be more appropriate).
I believe that is correct. We have seen in some cases where twinax cables appear to run some microcode or something similar on them that check the vendor of the switch and will fail if it is not as expected. This is not to say that someone out there doesn't make a cable that plays well with others, but we have not seen them. The key here though is to remember that NetApp Global Support may require certain cables and switch combinations depending on the devices and configurations using them, else you risk being unsupported. Be sure to check the compatibility guide and follow the current requirements for all of your configurations and designs.
We ordered two Brocade TX24 10GbE switches along with plenty of Brocade cables. (We distribute Brocade)
Installed with NetApp FAS3140A with 10GbE adapters, and HP Servers with HP 10GbE cards - HP Servers refused to bring up connection, ended up having to order HP Twinax cables to get the solution working.
Brocade switch does not seem to be affected. FAS to Brocade switch with Brocade cable is OK.
A reseller of ours was trying to connect an IBM Blade Center to a 10GbE CISCO environment with the IBM CNA (believe its a re-badged Brocade) with CISCO cables - would not work - sent them a couple of Brocade cables and they worked.
Have not been able to find any definitive document that explains what goes with what yet
If you add a 10GbE Adapter in Partner Edge, it now asks you to specify if you want CISCO or Brocade cables.
