Editor's Notes
- #2: Start with the coffee cup / vnx fiber issue story
- #22: Cpu architecture Uncore is a collection of components of a CPU that do not carry out core computational tasks but are essential for core performance, such as power management, interface to I/O devices, and memory controller. L3 cache, or last level cache, is shared between all of the active cores.
