Can I go network card to network card (no switch) with 40g? I have 10g nics in my computers now and during large file copies I'm maxing out the 10g (no switch). I'm currently doing 10g over cat6a and it is maxed.
I was considering getting 2 of the XL710-QDA2 cards and a XLDACBL3 QSFP+ to QSFP+ Twinax Cable |
Sorry – one more question – is there a noticeable difference between the performance of DAC and fiber? I hear CAT6 has more collisions or overhead or latency on 10gigabit (not sure what is true) than fiber.
Complete Systems Design
With your intended setup of back-to-back connection within 3 meters, there should be no difference between using DAC and fiber. Also, the XLDACBL3 cable features low cross-talk and pair-to-pair skew that maintains signal integrity. For more information about the features of Intel QSFP+ cables, kindly visit the link below.
Please let us know if there's other assistance needed.
