[j-nsp] EX4600 or QFX5110

[Alex Martino]

Hi,

I am seeking advices.

I am working on a L2/L3 DC setup. I have six racks spread across two locations. I need about 20 ports of 10 Gbps (*2 for redundancy) ports per rack and a low bandwidth between the two locations c.a. 1 Gbps. Nothing special here.

At first sight, the EX4600 seems like a perfect fit with Virtual Chassis feature in each rack to avoid spanning tree across all racks. Essentially, I would imagine one VC cluster of 6 switches per location and running spanning-tree for the two remote locations, where L3 is not possible.

I have been told to check the QFX5110 without much context, other than not do VC but only VCF with QFXs. As such and after doing my searches, my findings would suggest that the EX4600 is a good candidate for VC but does not support VCF, where the QFX5110 would be a good candidate for VCF but not for VC (although the feature seems to be supported). And I have been told to either use VC or VCF rather than MC-LAG.

Any suggestions?

Thanks,
Alex
