Part IV: Hyperconvergence

1, hyper-convergence is a product form of the post-virtualization era

2000 ~ 2010 belongs to the "pre-virtualization era", the core features are: based on the widespread use of x86 servers, server virtualization is the main line. Business level cloud computing concept from the proposed, development to the gradual landing, the underlying IT architecture of the data center is also constantly upgraded. Among them, with the intensive integration of computing resources, the bottleneck of the storage subsystem is becoming more and more obvious, and a new technology/architecture is needed to meet the rapidly growing demand, so the concept of software-defined data centers appeared, followed by software-defined networks, software-defined storage and other technologies gradually appeared.

Around 2010, we entered the "Post-Virtualization Era", where the underlying IT architecture moved from server virtualization to storage and network virtualization, and new cloud computing companies such as Pure Storage and Nutanix began to enter the field of vision, proposing hyper-converged solutions, starting with storage virtualization. The solution is to make sure that you have the best possible solution for your business.

2. The core function of hyper-convergence is a distributed storage system (storage virtualization) and a unified resource management platform

The first breakthrough in hyper-convergence is the realization of storage virtualization. The original SAN and NAS have higher requirements for architecture design and later operation and maintenance. Hyper-convergence is a simple storage virtualization solution that is highly scalable.

The second breakthrough in hyper-convergence is the realization of unified management of resources. Hyper-convergence is suitable for virtualization scenarios, VMware and other virtualization of computing, distributed storage to achieve storage virtualization, and even through NFV to achieve virtualization of the network, virtualization can be through the control surface platform for flexible deployment of resources. Hyper-converged vendors not only integrate and virtualize hardware, but also provide intuitive and easy configuration and management tools.

3, hyper-convergence to provide business-oriented integrated IT infrastructure solutions

Data center IT deployment of the technical evolution: traditional information technology architecture (computing, storage, network discrete) - & gt; ultra-large-scale Scale-out architecture (computing virtualization, software-defined storage, the design and deployment of maintenance of a more responsible) - & gt; Hyper-convergence? (There are currently some attempts)

The technological evolution of enterprise digital IT deployment: traditional information technology architecture - > integrated all-in-one (still the traditional discrete architecture, but the vendor integrated servers, storage, switches into a cabinet) - > hyper-convergence (business-centric, flexible scalability, easy to maintain)

4, hyper-converged application scenarios

p> Hyper-convergence four types of typical applications: (1) VDI (2) big data platform (3) ROBO (4) disaster recovery and backup

Desktop cloud / VDI : an organization using a period of seven nodes, used to support the migration and deployment of 400 VDI desktop; the second phase of the new 14 XC nodes, some of which are used for VDI expansion, part of which is used for the virtualization of the application servers, including the mobile securities

Big Data is a new generation of VDI desktops.

Big data platform: many domestic hadoop as big data storage (originally hadoop is to do big data computing), hyper-convergence happens to be a good storage solution. An organization using eight all-flash nodes, one of the core module quantitative analysis.

ROBO : Unified deployment of remote/branch offices, especially the global management of different server rooms in different regions, using Prism products as the management interface and interface. An organization deployed 120 nodes.

Disaster recovery and backup ：

二、Hyper-convergence main players and differentiation?

1, DELL EMC : 2015 nutanix and vmware is a very good partner, to 2015 after vmare launched vsan hyperconvergence software, nutanix also launched its own virtualization software AHV (using nutanix customers in 33% of the use of AHV). 2018 began the two sides of the cooperation is basically ended. From DELL EMC itself, the importance of hyper-convergence is gradually increasing, and in the future it may focus more on the expansion of large customers.

2, Deep Reliance: Deep Reliance has its own virtualization products and distributed storage systems, which should be developed based on open source software. Deep Conviction is responsible for hyper-convergence of the technical leader is the original vmware. The main advantages of DeepCloud's products mainly include network virtualization, network security, and a more friendly management interface. Compared to overseas vendors, the integrated network functions, especially security functions, are the core differences.

3, Xinhua three: integrated network virtualization features, Xinhua three software licensing cost control is very flexible, mainly through hardware sales profit.

4, Huawei: Huawei is more interesting, to the user first push storage series products, if the user has a hyper-convergence needs and then promote hyper-convergence. At present, Huawei's fusioncube has not yet integrated network functions, but if needed, it can also be quickly integrated.

5, wave: with vmware talked about a cooperation, in addition to wave is also with nutanix in the discussion of cooperation. For example, the bank has a project, Wave has been shortlisted, plus nutanix software can be used as a special model of Wave.

6, Lenovo: software strength is weak mainly OEM, and nutanix have cooperation.

Three, hyper-converged future trends?

1, Nutanix's future planning

nutanix planning for three stages:

(1) infrastructure hyper-convergence;

(2) hyper-convergence stage 2.0, in addition to hyper-convergence in addition to providing a management interface to connect to other infrastructures (hyper-convergence, public cloud, private cloud);

(3) Enterprise Cloud, in addition to doing the underlying resources, can do application delivery, and currently also acquired some projects to do enterprise applications.

2. Relationship with public and private clouds

The biggest competitor of hyper-convergence is the public cloud. But public cloud storage is generally running unstructured data (such as images, video), hyper-convergence is mainly for structured data. In addition, most C-suite services use the public cloud, but internal management and some production systems tend to use hyperconverged/private clouds.

Hyperconvergence can be seen as a form of private cloud. Customers who have a need for virtualization generally use hyper-convergence. From this perspective, hyper-converged architectures probably account for more than half of the overall enterprise cloud market. As far as banking customers are concerned, they are less willing to adopt the infrastructure of Ali and Tencent, and generally use Paas layer services (such as Baxin Bank, the big data analytics model provided by Tencent), but the IT infrastructure is built by themselves.

3, Nutanix why not do network virtualization?

Network open source software is openswitch, then openswitch was acquired by vmware, the market new entrants can not find the right network open source technology.
