[cs615asa] Meet up report exia

[Erte Xia]

Hello All,
For my meetup, I attended the New York SRE Tech Talks on April 26 at
Facebook's NYC Office.
The meet-up was divided into three parts:

I.G.I.G.E.E. Data-center network
The talker introduced "old" network topology and "New" approach topology
named CLOS topology. In other words, CLOS topology is every DCs connect to
all servers. In such topology, connections between servers do not depend on
the connections between DCs and the network will be still available even
though some of DCs go down.
