We're largely moving our data center operations to a colo facility, but we still have some that's going to hang around for a while. It is time to upgrade the networking gear. I'm looking for pizza box options (not chassis) and I'm having a hard time figuring out the differences between platforms.
Like, how is the QFX line different from the Nexus line? Should I be considering Arista as well?
This new core will be largely collapsed and catch all of our site-to-site connections (mostly dark fiber, some managed services) and will need to run OSPF to support these connections. It will also connect the new servers and new SANs. I'm pushing for using 10G SFP for the new servers and SANs, but we'll see. The new switches need to be 10G/1G capable in a potential mix of fiber and copper, multi and single mode. I specify the multi and single mode because I've noticed that some boxes seem to come with lc interfaces, and I'm not sure if they support one or both.
We're adding two servers and one SAN, and will need to support some legacy servers for a period of time.
