6500 Redundancy Question

Hello,

I have a question with regards to 6500 Redundancy. We currently have only one in our DC, it has 2 SUP 720s, two FWSMS, and multiple switchport blades. My question is is this fully redundant? and if not what is it that can fail, so I can look into adding that extra layer of redundancy. Any advice would be greatly appreciated. Thank You!

No, you have a single point of failure. If you lose the chassis, no matter how many supervisors you have - you have an outage. I recommend getting another chassis with similar modules and dual-home every single device.

Just wanted to expand on Edison's post, if you go the dual homed approach, "similar" doesn't have to mean identical.  Much depends on whether fail over has to offer same performance as before failure.

Also, with dual chassis, you might be able to migrate your 2nd sup to 2nd chassis and save some $.
