Can future data Center architecture replace minicomputer mode?

With the advent of the software definition era, business is growing, data volume and the pressure of the system also follow. From the traditional relational database to the dedicated data warehouse, from the minicomputer to the current popular x86 server, the technical architecture has changed greatly. Users need to focus on not just a single server or storage node, but the entire IT system, including the performance, security, and reliability of the overall system architecture. According to the traditional concept, users may be more inclined to choose minicomputer when they build enterprise data center, and now x86 server has made a qualitative leap regardless of performance, reliability and security. It is in this context that the integrated machine solution based on x86 architecture emerges. Integrated machine with high integration, fast deployment, easy maintenance, cost-effective and high characteristics. Can an All-in-one architecture replace the minicomputer architecture model in the future data center?

The bottleneck of minicomputer

Minicomputer has obvious advantages in single machine processing ability. This advantage enables it to perform better when dealing with a single application. But as the system scale increases, the traditional database architecture based on minicomputer faces various bottlenecks:

Server layer: Receive too much data for processing, memory advantages can not play;

Network layer: Insufficient transmission bandwidth, can not quickly transfer a large number of data to the server;

Storage layer: The volume of data is increasing, which brings IO bottleneck, and the data distribution is uneven with the data running for a long time.

The traditional and most effective way to solve the above problems is to expand the system to increase the number of channels and improve the processing capacity of the system, such as increasing the processor, memory, or increase network transmission bandwidth. However, the scalability of minicomputer is limited and the upgrade cost is high. In addition, minicomputer components are proprietary components, the price is more expensive, and poor performance.

One machine instead of minicomputer

One machine is a data warehouse device. In database application, the biggest advantage of one machine architecture is that it has excellent data processing ability. It separates the database from the storage. This separation is not simply physical separation, but the original database processing, part of the transfer to the storage server to deal with, in order to reduce the pressure on the database server, which is tantamount to adding hardware to provide processing power. With the development of technology, x86 server from the performance, reliability, availability and so on, with a higher capacity of minicomputer, the cluster model based on High-performance X86 server to replace the model based on minicomputer has become a trend of development. Many domestic users have begun to "go to IoE" process, including some large internet manufacturers and financial, telecommunications and other industries users.

The advantages of the integrated machine

Nanjing Titan Company's All-in-one machine including the Cloud Bridge database one machine and the Cloud Bridge application one machine two kinds.

Cloud Bridge Database Integrated machine, based on the x86 processor, using a clustered architecture, Oracle, MySQL and other databases and InfiniBand network, Cloud Bridge storage, as well as cache technology, and adapt to optimize, so that a good solution to capacity scalability, Issues such as stability and storage resource utilization. Stender deputy general Manager and technical director Cho Hao said: "The Cloud Bridge Database integrated machine simplifies the deployment, debugging process, so that users can in the shortest time possible to build an efficient and stable database operating environment." ”

Cloud Bridge application integration of computing, storage, network and other hardware, as well as virtualization platform, cloud computing platform, cloud management, cloud applications and other software, in the integration, automated deployment and efficient operation and maintenance on the basis of the user to provide efficient cloud business application services. It is a data storage, processing, display a full link, software and hardware integration of the solution, is the enterprise and institutions to build cloud business application platform is one of the ideal choice. One of the features of the Cloud Bridge application is to support desktop virtualization and server virtualization.

Stander Bridge is a major feature of the use of InfiniBand technology, through the InfiniBand network, in the database node and storage nodes to transmit data, the switch can provide 40G per second throughput, which greatly improve the network transmission capacity, solve the problem of network bottlenecks. If the user has already widely used Ethernet technology, then can InfiniBand still play its role? With this in mind, the--infiniband and IP protocol conversion technology, which is developed by Titan, allows InfiniBand and Ethernet to "coexist harmoniously", So that the two technologies in their respective areas of expertise to fully play their role, thereby eliminating the user's concerns.

1. Bandwidth Advantage

In the transmission bandwidth, the most common minicomputer can use the HBA card for 4Gb, so the theoretical IO bandwidth is 4Gb. With the Oracle RAC Parallel Processing mechanism, the InfiniBand technology can be used between compute node and storage node, the single node is up to 56gb/s transmission bandwidth, and the x86 architecture Oracle RAC Server has more concurrent processing capability and greater IO bandwidth.

2. Price/Performance Advantage

In estimating the cost of a system, enterprises should consider the following aspects: The cost of the system hardware investment, the management and maintenance of the system, and the scalability of the system.

From the point of view of system hardware investment, the scheme of minicomputer is much higher than that of domestic manufacturer database cluster.

From the management and maintenance of the system, the maintenance of the minicomputer system every year, the need to buy a factory service every year, only the factory fees in hundreds of thousands of yuan to millions of dollars. The open architecture of the integrated system, compared to the closed architecture of the small machine system, the technical requirements of managers are relatively lower.

From the expansion of the system, the expansion of the minicomputer system can only be expanded by the way of accessories, such as upgrading the CPU, and according to the Law of computer technology development, the feasibility of expanding equipment accessories is very low. The integration system supports both vertical and horizontal extensions. The so-called portrait, refers to the increase of a single server configuration, such as CPU frequency, the number of upgrades. Horizontal refers to the increase in the number of devices, such as the database node with 4, the latter can be extended to 6, 8.

Stander Bridge adopts a scalable architecture to host database servers and storage servers, balancing CPU, I/O and network throughput, and avoiding bottlenecks. As the volume of business grows, users can add database CPUs, storage, and networks in a balanced way, ensuring scalability without creating bottlenecks.

The Scale-out architecture is adaptable to any scale of load, allowing for seamless scaling from small configurations to large-scale configurations, while avoiding performance bottlenecks and single points of failure.

Dr Cho Hao, technical director of the company, has summed up the technical features of the Cloud Bridge series: Support for HA (availability), dynamic resource allocation, failover and reconstruction, support fast flash memory technology, IOPS up to 1 million (database integration machine), the system has been completed before the installation and pre-configured, delivery can be used; can support at the same time more than 1000 daily Office virtual Desktop (application integrated machine), with a large amount of security storage capacity, capacity can be extended to PB-class.
