1. Box Model
When CSS processes webpage content, it puts every element in a box, the so-called box model.
The box model consists of four parts: content, padding, border, and margin)

There is a pitfall in the box model, that is, when taking the height and width of an element, you can specify the heig
, with a port number ranging from 16 to 256 per chassis. Because building a large storage network requires not only high port density.
As a result, Cisco has introduced many new features, making the multi-layer storage network a reality. Virtual SAN, advanced traffic management, hardware maintainability, and comprehensive security make the Cisco MDS 9000 Series A preferred platform for enterprises and provide them with the highest scalability and lowest TCO.
