choosing a switch.... cat6500 vs cat6800

[Eli Kagan]

Hi everybody,


Need your opinion on choosing a switch for an upgrade. I got a bunch of cat4507 sup7-e running right now thatneed to be replaced very soon.  I can’tseem to pick the right platform to replace it with. Cisco is being as confusing as always.
My requirements are pretty bland. The switch has to be highly reliable (banking environment), mature code and hardware. Should not end up with no more software updates in the next 5 years (PCI compliance). Should do VRFs, MACsec, VPC or VSS (quad sup VSS is better). No 10Gig is required as of today.
My options so far:1.       Cat6807, sup6T  -- would be my first choice but other techies have no experience with it and are reluctant to agree.

2.       Cat6506-E.  sup2T  --  7 years old, perhaps will be EoL shortly otherwise will do.
3.       Cat4507R+E, sup9 -- good on paper but I had too manyhardware and software issues with the existing cat4500 for me to be comfortablewith this option. On top of that, Cisco is “encouraging” to go to Cat9400instead 
4.       Cat9400 7-slot  --  I know nothing about that thing. Does it support quad sup VSS or similar? Is it too cutting edge for a financial client? Is the code stable enough?


5.       Nexus 7700 6-slot   or    Nexus 9504   --  both are expensive ashell.
Any insight would be highlyappreciated.

 

 
Thanks,

Eli
