虚拟化 超融合 优缺点(用超融合还是虚拟化)

The advantages of hyper-convergence are as follows:

1. Simplified management: The hyper-convergence platform integrates computing, storage and network, which means This allows users to manage all resources in a single management interface, greatly simplifying the IT management process.

2. High availability: In the event of physical hardware failure, the hyper-converged platform can automatically migrate data and applications to other healthy nodes, ensuring business continuity and high availability.

3. Flexible expansion: The design of the hyper-converged platform allows it to be flexibly expanded according to business needs. Whether it is adding nodes or increasing storage capacity, it can all be done online. , without interrupting business.

4. Improved performance: The hyper-converged platform tightly integrates computing and storage resources, allowing data access and computing to be performed more efficiently, improving overall performance.

5. Cost-effectiveness: Hyper-convergence technology reduces the total cost of ownership (TCO) of IT equipment by integrating hardware resources, improves resource utilization, and further reduces operating costs.

Applications of hyper-converged technology:

1. Virtualization environment: Hyper-converged technology can provide an efficient virtualization platform and support a variety of virtualization technologies, such as VMware, HyperV and KVM wait. It provides functions such as dynamic resource scheduling, data backup and recovery, and improves the availability and performance of virtualized environments.

2. Cloud services: Hyper-convergence technology can build private clouds or hybrid clouds, provide elastic computing, storage and network resources, and support a variety of cloud services, such as Infrastructure as a Service (IaaS) and Platform as a Service. Services (PaaS) and Software as a Service (SaaS), etc.

3. Big data analysis: Hyper-convergence technology can integrate big data analysis tools, such as Hadoop and Spark, to provide high-performance data processing and analysis capabilities. It can also support functions such as real-time data stream processing, data mining and visual analysis.

4. Containerized applications: Hyper-converged technology can be combined with container technology to provide a containerized application operating environment. It supports microservice architecture and DevOps processes, improving the efficiency of application development and deployment.

5. Backup and recovery: Hyper-convergence technology can provide reliable backup and recovery solutions and support data backup, recovery and disaster recovery. It also enables fast data retrieval and recovery, improving data security and availability.

1. What is hyperconvergence? What are the advantages?
Speaking of this, we have to first mention the product that hyper-convergence replaces: traditional IT architecture.
From the case descriptions of hyper-converged vendors such as Nutanix and VMware (vSAN) in foreign countries and SmartX in China, we can see that a large number of the products they replace are storage products from established storage vendors EMC, HDS and other companies. product.
Therefore, users purchasing hyper-convergence do not have to replace the original server brand (such as Dell) or virtualization brand (such as VMware), only the storage (such as EMC) must be replaced.
So the most significant difference is the storage architecture. Hyper-convergence uses distributed storage, which can build an easily scalable and highly reliable storage resource pool based on X86 servers. This is super The basis of integration is also the core technical point.
The difference and comparison between traditional IT architecture and hyper-converged architecture
Specifically, there are the following differences:
Physical convergence and management convergence : Hyper-converged architecture integrates servers, networks and storage, and installs them on a unified management platform for maintenance; while traditional architecture is all separated.
Storage architecture: Hyper-convergence uses distributed storage, while traditional architecture uses centralized storage.
Network: Hyper-convergence uses 10 Gigabit Ethernet, while traditional architecture mostly uses fiber-optic switches.
Reliability: It can be seen that in terms of reliability, the advantages of hyper-converged architecture are very great, but in fact, the advantages here are all distributed storage itself should have.
Performance: The architectural advantages of hyper-convergence in terms of performance are very obvious. Of course, the cost is the consumption of computing resources, so the consumption of computing resources is an important factor in testing the professionalism of hyper-convergence.
In terms of scalability: the hyper-converged architecture has strong scalability, simple and fast expansion, and system complexity will not increase with expansion.
In terms of deployment and operation and maintenance: compared with traditional architecture, hyper-converged layout, simple maintenance, and capable of intelligent operation and maintenance to a certain extent.
2. What are the benefits of hyper-converged all-in-one machine?
Hyper-converged all-in-one machine refers to an out-of-the-box, all-in-one machine delivery method that manufacturers provide users based on customer needs and their own product strategies. The all-in-one machine includes software and manufacturer selections. Customized and adapted x86 server.
It can be seen that it can be used out of the box and integrated delivery is its biggest advantage. The advantages are more obvious in terms of simplified deployment, maintenance, availability, and reliability.
The details are as follows:
1) Simplified deployment and accelerated business launch time
In the past, when enterprises deployed their own IT systems, they often needed Purchasing different equipment requires a long installation and debugging process, which may even affect the business launch time.
With hyper-converged all-in-one machines, enterprises only need to purchase one such product. The installation and debugging process is very convenient, which greatly simplifies the difficulty of deployment and speeds up the time for business to go online.
2) Reduces the difficulty and cost of operation and maintenance
In the past, as many different types of hardware equipment as the company had, it required as many different professional technicians to use hyper-converged all-in-one machines Finally, the difficulty of system management is reduced, and a technician can easily handle it, which reduces the difficulty and cost of operation and maintenance.
3) Improved equipment reliability and availability
Hyper-converged all-in-one machines are much less prone to equipment failures. Even if problems occur, they are relatively simple and fast to solve. , which greatly improves its reliability and availability.
4) Saves expenses
Compared with the purchase price of an IT system composed of multiple devices, the price of a hyper-converged all-in-one machine will be much lower.
3. How about Lenovo’s hyper-converged all-in-one machine?
The 2019 Gartner China Hyper-Converged Vendors Competitive Landscape Report lists nearly ten domestic hyper-converged vendors including SMARTX, which is a relatively good reference.

Hyper-convergence is inspired by the construction of large-scale data centers through software-defined technology, combining virtualization technology and enterprise IT scenarios to achieve scalable IT infrastructure for enterprises;

< p>The current domestic Lenovo hyper-converged all-in-one machine is an IT infrastructure that uses distributed storage and computing virtualization technology to integrate server clusters and provide computing, storage, network and other resources to the outside world. Help customers significantly reduce the complexity of data centers of all sizes.
