sentence on fault tolerance/mtbf doesn't make sense
This article currently says (in the lede): """At some point, the number of discrete systems in a cluster will be greater than the mean time between failures (MTBF) for any hardware platform, no matter how reliable, so fault tolerance must be built into the controlling software."""
The number of systems can't be "greater than" a time. (5 servers is greater than an hour? 10 servers is greater than a meter?)
There's 2 refs for that sentence atm and I wasn't able to read either of them. One is a journal article behind paywall and one is 404 (but might be available in wayback machine). Can't look any further right now, maybe later. --Jeremyb (talk) 21:29, 30 November 2013 (UTC)
