Quoted: • 4000 nodes
• 2 quad core Xeons @ 2.5ghz per node
• 4x1TB SATA disks per node
• 8G RAM per node
• 1 gigabit ethernet on each node
• 40 nodes per rack
• 4 gigabit ethernet uplinks from each rack to the core (unfortunately a misconfiguration, we usually do 8 uplinks)
• Red Hat Enterprise Linux AS release 4 (Nahant Update 5)
• Sun Java JDK 1.6.0_05-b13
• So that's well over 30,000 cores with nearly 16PB of raw disk!

Quoted: How is that the conclusion?! The conclusion should be: in small numbers of data points, there is bound to be enormous fluctuation. This is like saying: yesterday it was sunny, today it poured. Surely, some Fertility God disapproved of our elk sacrifice.
