Shulou(Shulou.com)06/01 Report--

Reopen a blog that has been abandoned for five years. When I came back, I found it was overgrown with barren grass.

It has been six years since the implementation of the Cisco datacentre program in 2010. The purpose of opening a blog is to record the process of preparing CCIE DC and HCIE DC, and to urge myself to summarize knowledge points every day.

Cisco CCIE DC has been updated to V2, adding the long-awaited VxLAN, and ACI. Also feel that the content of V1 is too simple, has not been to take the CCIE DC. This time, I'm going to do everything I can.

HCIE DC and CCIE DC are completely different exams. The content and method of the exam are completely different. Huawei's things have been criticized, they are too close to the market, close to users. Cisco always leads the technology and market, like a car made by a standardized process, stylish, rugged, and stereotyped. Huawei is like a small tricycle sold in supermarkets and handicrafts. Personalized, low profit and quick turnover. There are no advantages or disadvantages in technology, and users will pay if they can meet the needs of users. Huawei also uses the way of copycat phones at that time, with a large number of personalized and high-quality services to capture the market. Cisco follows iPhone's arrogant route and only does the best.

CCIE DC and HCIE DC are on my exam preparation schedule. Interested friends, join QQ group 105626233, let's do it together.

Preliminary plans by the end of the year:

Network part

Fabric concept

Trill concept (old stuff, hardly deployed, as an introduction to challenges in the data center)

Fabricpath (purely Cisco stuff)

The first draft of VxLAN (basic content, write whatever comes to mind, review and summarize a process)

EVN, E × × first draft (this is a new thing, write it in several times)

Storage part

1. Later, I will begin to prepare for the exam, and the storage part is only going to write FCOE.
