The people around us it
- In life it
Including but not limited to the following , For example, baidu cloud , Cloud notes , Online music app All belong to cloud !
Or it can be understood as , As long as the storage is not local , It's called ” cloud “ turn . - At work it
The definition of Cloud Computing
- National institute of standards and technology (NIST) Definition :
Cloud computing is a model , It can realize anytime, anywhere , Conveniently , Get the required resources on demand from the configurable computing resource sharing pool ( for example , The Internet 、 The server 、 Storage 、 application 、 And services ), Resources can be quickly supplied and released , Minimize the workload of managing resources and interaction with service providers .
Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction. - Generally speaking , cloud , It's the Internet 、 A metaphor for the Internet , That is, the abstraction of the Internet and the underlying infrastructure needed to establish the Internet .“ Calculation ” It refers to the computing services provided by a sufficiently powerful computer ( Including various functions , resources , Storage ).“ Cloud computing ” It can be understood as : Through the Internet, you can use a sufficiently powerful computer to provide services for users , The usage of this service can be described in a unified unit .
Five basic characteristics of Cloud Computing
- 1、 Self service on demand (On-demand Self-service)
I don't know you know “ cloud ” no , For example, Hua Weiyun , Alicloud and so on , You can buy virtual machines in it , And then the memory 、cpu、 Storage can be dynamically expanded or shrunk , This is called on-demand self-service . - 2、 Extensive network access (Broad Network Access)
such as 4G,5G etc. . - 3、 Pooling resources (Resource Pooling)
Does the server have a concept ? Set up the server as a cluster , Such as openstack,VMware And other virtualization functions . - 4、 Fast flex (Rapid Elasticity)
Whether it's self-service , Or what we said in resource pooling , Can achieve this function , Elastic expansion mainly refers to : Memory 、cpu、 Storage 、 The Internet - 5、 Measurable Services (Measured Service)
1 Self service in , You need money , Then money is provided by measurement services , For example, how much is the virtual machine you configure for an hour, a day, and a month .
Cloud computing 4 Class deployment mode
Private cloud (Private Cloud)
Enterprises use their own or leased infrastructure resources to build their own cloud ;
Community cloud / Industry Cloud (Community cloud)
A cloud of shared infrastructure built for a specific community or industry ;
Public cloud (Public cloud)
The cloud of large infrastructure leased to the public ;
A hybrid cloud (Hybrid cloud)
A cloud consisting of two or more deployment patterns ;
Cloud computing 3 Service modes
- 3 Service concept
- Detailed correspondence
Cloud infrastructure as a service (IaaS)
Rental processing capacity 、 Storage space 、 Basic computing resources such as network capacity ;
Cloud platform is service (PaaS)
Provide a deployable cloud environment for customer developed applications ;
Cloud software as a service (SaaS)
Provide applications on the network that can directly make ;
Cloud computing 8 Common points
- On a large scale (Massive scale)
- Homogenization (Homogeneity)
- virtualization (Virtualization)
- Elastic calculation (Resilient computing)
- Low cost software (Low cost software)
- geographical distribution (Geographic distribution)
- Service orientation (Service orientation)
- Advanced safety technology (Advanced security technologies)

Huawei products
- Since it belongs to Huawei cloud Series certification , Of course, you need to know where Huawei products are purchased ~
In these years of work, I have encountered almost all manufacturer servers 【 Including minicomputers 】, Others don't say , Simply take management mouth as an example , I think Huawei is the most user-friendly management interface , Not one of them. . As for why , In the future, you can contact Huawei's servers , And there are servers from other manufacturers , You will know what I mean when you enter the management port . - Official website address : Huawei cloud official website
Huawei cloud account and Huawei account are shared , So you can log in directly with Huawei account .
Huawei cloud computing products
- Cloud computing is what we often call virtual machine , If you need it, you can buy it directly on this interface
- Domestic and foreign network requirements need to be filed , The advantage is that it's cheap .
- Abroad The external network does not need to be filed , The disadvantage is that the price is too expensive .
Huawei enterprise product description
- Huawei's various scene websites are different , But the account number is universal , Here you can also log in directly with your existing Huawei account .
Official website address : Huawei enterprise products
Huawei server description
Server introduction official website address : Computing products 3D Exhibition
notes : Huawei is no longer selling x86 Architecture server , main
arm framework
Server for , So you can see , It's basically arm Server model of the architecture .
Such as :TaiShan And Kunpeng series servers .
Server model introduction 、DDR Channel configuration description
The name is usually xxxx Format , Such as :TaiShan Series of 2280 Server model decomposition :
2280:
- 2: 2U 【 Server size , Server cabinets are all based on U Unit 】
- 2: Physics cpu Number 【 commonly 1 individual cpu Corresponding 4 passageway 16 Memory modules ( A passage 4 Memory modules )】
- 8:DDR passageway 【 Number of memory 】
- 0: Not specifically 【 commonly :8 finger x86 framework ,0 finger arm framework 】
DDR Access map
- cpu The name is cpu0 and cpu1【 That is from 0 Start on the th 】
- DDR Meaning of existence : without DDR Only one memory module can be transferred at a time 【 No matter how many memory modules you have 】
- But with DDR Then what? , Memory modules cannot be inserted randomly , Otherwise, the power on self-test cannot be passed, resulting in failure to power on , Or the performance is not optimal .
DDR To configure , We can go to the tools section of the official website 【 Basically, all the problems you can think of can be found here , Therefore, Huawei has done very well in this regard 】
What we need here is to calculate the memory configuration , So click : Intelligent Computing - Only the product memory configuration assistant can be calculated
We take Mount Tai as mentioned above 200 Series server as an exampleEnlarge the picture and DIMM explain , Such as :
DIMM110
- 1: That one CPU
- 1:CPU The number of DDR passageway
- 0:DDR Which memory module of the channel
There is nothing to say
As I do 14 root , Will be empty 2 Come out of a position , Pictured , Anyway, how many memory modules do you have , You can get as many as you want , Just plug in ok
Memory above cpu In short , So storage , The data stored in the server must be stored in the hard disk , But the hard disk of the server and we pc Your hard disk is similar , But there's a difference in how it's used , The server will do for the hard disk raid, About raid, My previous article explained , You can get to know :
RAID0、1、3、5、6、10、50 And hot spare ultra detailed description
