Backplanes still used? What is the modern equivalent?

[2002rover]

Are backplanes still in use? Is it that these functions are now on the motherboard?

What is the modern day equivalent to the backplane?

Thanks

They still use backplanes in blade servers. Many of the higher end iSeries do the same thing. The Cisco chassis switches are backplane based.

A lot of rack servers still use backplanes too. But the backplanes don't really do any functions besides providing connection to the rest of the server.

A backplane is a circuit board containing [only] a bus. If you don't require the bracketed word in your definition, a motherboard is a backplane. If you do, that's the difference.
