Oracle 11.1.0.7.0 and cell physical IO interconnect byt-es

I've been playing around with 11.1.0.7.0 and noticed the system statistic "cell physical IO interconnect byt" in a statspack report. There are no references to this statistic on metalink whatsoever, however there is a reference on Kevin Closson's blog stating that this is an exadata related statistic, not that I dispute Kevin's information, but I'm not using exadata, this is something I'll try to bottom out with Oracle support.
