大学

香港大学孙教授的一段话：

大学，就应该是早起吃点早餐；跑跑步；专业课认真听；公共课看看自己喜欢的杂志；中午小睡一会儿；下午参加个社团活动或打打篮球；晚上陪着喜欢的人散散步；或去自习室安安静静地看看书……

社会不需要学霸，也不认什么学生会主席，更不希望看到学生放弃学业去创业。你只要能平稳完整滴读完大学，寻找到自己所爱的人和兴趣，多去没有目的的看些能丰富自己思想的书，认识几个好得不成样子的朋友，锻炼或是塑造自己的身体，学精自己想要从事事业的专业知识……

做到这些，平淡地度过大学这几年你就已经足够优秀了。

深以为然。

Converged Infrastructures (CI) vs. Hyperconverged Infrastructures (HCI)

• Converged infrastructure relies on hardware and employs building blocks. Hyperconverged infrastructure relies on software-defined. 
• The main difference between CI and HCI involves the rack system. A large, rack-scale platform that merges compute, storage, and networking into a turnkey product is CI, while HCI normally consists of a 1U or 2U (rack-unit) systems that consolidate one or more multi-core servers with a local storage array. 
• The architecture varies between the two approaches. “Converged architecture storage is attached directly to the physical server” and "the HCI architecture has a storage controller function that runs as a service on every node in the cluster."
• HCI shares storage to all compute and virtual machines (VMs), whereas CI does not. 
• HCI is often deployed on commodity components; providing a simplified scale out architecture with commodity servers. 
• HCI is more flexible, manoeuvrable, and scalable than CI. 
• HCI does not replace CI. They contain unique benefits.
