Nimble HF20 array connecting to Cisco Switch using copper DAC cables

Hi All,

We are going to implement a HF20 array with 10GbE connectivity using the Q8B89B 4x10GbE 2-Port NIC option. This will be connecting to a pair of Cisco 10GbE SFP+ switches.

Can we use Copper DAC cables to connect the array to the switches or do we have to use 10Gb transceiver modules and Fibre Cables. We would like to use DAC cables to save a bit of money.

Many thanks in advance

Steve

Dear Steve,

I've got a lot of performance trouble with DAC cable in the past and high rxErrors at tg1 and tg2.

I found Nimble KB-Artikel about compatiblity issue with DAC Cables from major vendors brands.

At the end of the day I moved to Optics /Fibre Cabels and everyting works like a charm.

Yes Optics are more expensive but more reliable.
