Software Defined Storage, Distributed Storage or Hyperconverged Appliance?

Definitely choose distributed storage, which emphasizes data security, and can avoid many common data loss risks such as hard disks, server damage, and silent data corruption. If it is an ordinary small and medium-sized enterprise, mainly deploying some static **, the storage demand is not large, the data security requirements are not high, and the risk of data loss can be tolerated, you can use the hyper-converged all-in-one machine. Our company is responsible for IT for about 10 people, using the VMware virtual machine plus yuan core cloud distributed unified storage solution.

Hyperconvergence refers to the convergence of compute, storage, and networking.

Computing generally refers to virtualization, storage generally refers to distributed storage, and network generally refers to SDN. Distributed storage doesn't have to be a distributed file system, but it can also be distributed block storage. In hyper-converged scenarios, what users see is generally distributed block storage

That is, for each compute unit (virtual machine).

Provides distributed storage of virtual hard disks (block devices).

When a customer's IT budget is limited and IT capabilities are limited, they will tend to hyperconverge because buying one thing solves all the problems.

However, when the customer's IT environment becomes larger and more complex, the service requirements of hyper-convergence are reflected, for example, when expanding the hyper-converged business, Shenzhou Cloud Technology adopts the method of providing user testing machines first, on the one hand, to help users understand what kind of solutions are needed to cooperate in different needs and application environments in order to maximize the benefits of users.

On the other hand, through the test of actual use scenarios, the pre-sales engineers of China Cloud Technology work with users to jointly design a more intelligent, friendly, scalable, and cost-effective hyper-converged solution. To this end, Shenzhou Yunke proposes a service"Three first-class"Commitment, first-class technical ability, first-class response time, first-class service attitude"Therefore, Shenzhou Yunke can smoothly enter multiple hyper-converged application fields such as finance, medical care, education, manufacturing, and security.

The concept of hyper-convergence is mainly embodied in the hyper-converged all-in-one machine, which combines computing and storage, connects them through software-defined form, and then centralizes them in one machine to provide services to customers.

Hyper-convergence is more suitable for small and medium-sized enterprises with small business volume and limited space, and a small number of hyper-converged all-in-one machines can provide small and medium-sized enterprises with sufficient network, computing, storage and other services. However, with the development of the enterprise's business, when the proportion of computing, network, and storage consumption shifts greatly, and the enterprise has more storage and computing than the service requirements provided by the original hyper-converged all-in-one, the purchase of hyper-converged all-in-one will cause a waste of other resources in the hyper-converged all-in-one. This necessitates the purchase of independent distributed storage to solve the storage problem, or the independent machine to solve the computing needs.

However, some hyper-converged appliances do not support separately purchased distributed storage systems, which makes the contradiction of enterprise resources more serious. At the same time, hyper-converged all-in-one machine manufacturers have to take into account multiple storage and computing services, so there will be a certain gap between the professionalism and reliability of storage products and the storage products of companies specializing in storage.

Therefore, with the development of enterprises, it is an inevitable trend to move from hyper-converged architecture to non-hyper-converged architecture.
