We are going to need more 100Gbps data centre switching in other PoP's 
in the coming months, and we like the 7508E for this, even if Arista 
have EoL'ed it. So for those builds, we'll grab them off the open 
market, and cold spare with a full chassis in copy. Way cheaper than 
when we bought them from Arista, even with the ongoing mark-up on the 
pre-owned space.

Arista are also not developing anymore new or maintenance code for the 
supervisor that runs on the 7508E, but we are fine with that because 
this is not an Internet-facing box, and is only doing Layer 2 with 
features that will never change (802.1Q and LACP is about as advanced as 
it gets, for us).
