Sounds like a question for resellers.

I can tell you that I just bought Cisco 4500-X core with 3650 aggregation switches, but I needed fewer 10G ports than you do. I also was more interested in having the enterprise feature set that comes with IOS vs the datacenter features from the nexus line. We almost got a pair of Nexus 9372PX switches, which have 48 SFP+ ports and 6 40 GB ports. The Nexus line can be expanded via Nexus 2000 series fabric extenders, which are best thought of as external blades or line cards in a chassis based system. The N2K-C2348TQ has 48 100M/1G/10G BaseT copper ports, with 6 QSFP+ (40 GB) ports. The 2348UPQ has 48 SFP+ ports (2:1 oversubscribed) with 6 QSFP+ ports. You can combine all three of those models together to get you all of the copper and fiber ports you want. Pair up the Nexus 9K into VSS mode where both chassis act as a single switch, and they continue to forward and L2 and L3, even during upgrades or failures. Spanning tree won't block any links with this design. I expect that I will be able to do maintenance on my switches, including firmware updates without ever needing to take my servers offline (plug each server into to separate switches).

Of course, everything these days has hot swappable power and fans. Pick your airflow direction (front to back or back to front).

I found the Cisco solution to be very well priced, especially the Nexus solution.

I can't comment on Extreme, as they didn't have the features I needed.

Are you looking at HP, since you want to integrate with their management?

BTW, all enterprise vendors have hardware that should meet your requirements. I don't know how others handle in-service upgrades (ISSU) to avoid downtime when upgrading code.

Again, I suggest you contact separate Cisco and Extreme resellers.

I wonder if the 6800 series (replaced the 6500 series) Cisco switch would work for you.  You can get the routing module to do everything that you need.

The 6807-XL with the SUP-2T is what you need.
