I guess many of you have been disappointed that you cannot get what you really need when using VXLAN:
You can do VXLAN routing but only at 10/40GbE, while you want to run 25/100GbE (without using a loopback cable…)
You use VXLAN as you need a scalable network but you are unable to support more than 128 ToRs because some ASICs are limited to not more than 128 remote VTEPs per VNI
You like the SFP form factor and would rather use a switch with SFP28 ports, rather than using break out cables
You need more bandwidth going up, and after using 2 ports for mLAG, 4 ports are not enough when using 25GbE NICs
You want a switch running Full line rate with ZeroPacketLoss
You want a switch with fair buffering as all cloud/Data center tenants should get the same service unless defined otherwise, and you want to deliver QoS to customers
With Mellanox Spectrum switches, running Cumulus 3.4, all these issues are solved, no need to choose between features, performance and scale. One ASIC can do it all and you don’t have to worry about all the hidden licenses you see from some vendors, it is all included, transparent and well tested.
