Wherever or where ever?

Which is correct?
_________ a virtual server runs, its storage volumes should be accessible.
a. Wherever
b. Where ever

Answer: a.

Explanation:
Wherever is the approved MLA, AP and APA style. I suspect the same holds true for whenever and whatever.

I did a quick Google poll on these:
wherever: 57,800,000 hits
where ever: 4,020,000 hits

Just for fun, I threw in “whereever” and got 78,000 hits. Not close to 57,800,000 but still a significant number. And among the prominent results were references to song titles by Metallica and Shakira and, um, “Brayan” Adams. I don’t like to cast aspersions on the spelling ability of Shakira and Metallica fans but… they say Google doesn’t lie.
