Understanding vSphere Active Memory

Understanding vSphere Active Memory

“Many people wrongfully assume that since active memory is not really changing, that the virtual machine is only using that amount of memory. “

Critical point here.  Although you might have a VM that (e.g.) averages 50% active memory, there is no guarantee that it’s the _same_ 50% from polling interval to polling interval (20s for “Real-Time”.)

IOW, you can’t…

Mysterious Coin-Covered Wishing Trees

The strange phenomenon of gnarled old trees with coins embedded all over their bark has been spotted from the Peak District to the Scottish Highlands in the United Kingdom. One of the larger collections can be seen in the picturesque village of Portmeirion in Wales where there are seven felled tree trunks with coins pushed into them.

The coins are usually knocked into the tree trunks using stones by passers-by, who hope it will bring them good fortune. These fascinating spectacles often have coins from centuries ago buried deep in their bark, warped from the passage of time.

The tradition of making offerings to deities at wishing trees dates back hundreds of years and is similar to the concept of a “wishing well”, where one tosses a coin in for good luck. The “wishing trees” date back to the early 1700s in Scotland where ill people stuck florins into trees with the idea that the trees would take any any illness. However if someone were to take away any of the coins, legend states that they will become ill instead.

Duodecuple!

According to Wikipedia, the latin name for a grouping of 12 is a duodecuple.  Duodecuplecore (duodecore?) doesn’t exactly roll of the tongue like hexcore or octocore does it?

Well, get used to it because Intel is rolling out new 12 Core Xeon (E5)…
