Why cloud storage is slow

Complex system, lack of complete industrial chain someone

From 2002 onwards, 3PAR Company began to advocate the concept of public storage. Cloud storage is built on the basis of public storage. A public store is a pooled storage resource that integrates all of the NAS, San, and so on. "In some ways, public stores can be equated with cloud storage. "The public store has three characteristics: self-management, high efficiency, can be applied to different environments and has good elasticity," said Craig Nunes, vice president of the 3PAR marketing company. ”

By May 1999, 3PAR had keenly observed the emergence of new IT architectures-public computing. Today, public computing enables IT organizations to provide service software (Software as a service) and serviced hardware (hardware as a services) through server and storage virtualization. On the common computing platform, enterprises can realize the application of public service, cloud computing and next generation service Oriented architecture. Conceptually, cloud computing is a service enterprise it that is offered on the Internet by external business-to-business or Business-to-consumer service providers. Cloud computing is a service or service hardware that is distributed through hyperlinks. "3PAR Public Storage is the storage foundation of common computing, and with server virtualization technology, you can create a complete public computing environment," says Craig Nunes. 3PAR's highly virtualized, public-based storage enables data centers and IT organizations to completely discard traditional single arrays. ”

"There are three reasons why cloud storage cannot be quickly popularized: system resource utilization is not high, system management is still very complex and business development is unpredictable." "One prerequisite for the popularity of cloud storage is the need to form a complete ecosystem," says Craig Nunes. 3PAR has made a useful exploration in this respect. At the end of 2007, 3PAR combined HP and VMware launched a program called 3cV that integrates 3PAR inserv storage servers, HP Blade Systems C-class, and VMware virtualization architectures to provide users with a complete public computing solution. Once launched, this scenario was successfully deployed at Deutsche Bank, helping users halve the cost of servers, storage, and operations while gaining greater storage agility. The common storage, virtualization architecture and Blade Server system constitute a complete ecosystem of cloud storage applications.

According to Gartner, in the North American cloud storage market, 3PAR is ranked second in the market share. 3PAR Cloud storage solutions are successfully applied across multiple sites. such as the MySpace site has chosen 3PAR storage platform, the highest can achieve 2 million people at the same time online. "In terms of cloud storage, 3PAR differs from IBM and EMC in that IBM and EMC provide the relevant cloud storage services themselves, while 3PAR only provides cloud storage solutions and does not provide related services," says Craig Nunes. ”??

Two types of services that are easily overlooked

"Figuring out what cloud storage is is not as important as knowing what cloud storage can do." "Now, there is no unified concept of cloud storage in the industry," said Cui Uit, vice president of the company. To put it simply, cloud storage is a service based on the Internet, with the basic features of mass storage, random reading, Real time expansion, SaaS, unified management, super security and resource sharing. ”

As Cui has said, Uit is a practical representative of cloud storage applications, and its cloud storage solution Webdisk has been launched 4. 1 version. Webdisk is a network form of file management system, that is, network hard disk. Its main feature is to allow users to manage files anytime, anywhere. Whether you are at home, in your organization, or anywhere else, users can manage files stored on remote Webdisk systems as long as they can connect to the Internet, and even share their files with others, just as you can manage files stored locally. Webdisk's core is file transfer, policy customization and space management, its main functions include: File upload and download, audio and video files online playback, breakpoint transmission, policy-based automated transmission, transmission task Queue management, System management, space management, user management, web-based access, Based on the client access mode, System alarm function, System report function.

Cui has introduced two features of Webdisk, Peer-to-peer and duplicate data deletion. Network bandwidth is a major bottleneck in providing cloud storage services. Because Webdisk adopts Peer-to-peer technology, it can greatly improve the ability of large file transfer in narrowband environment. Webdisk can support the transfer of 50GB large files. According to the introduction, Webdisk 4. The 1 version can improve the performance of the network transmission 3~5 times. Webdisk also uses UIT's patented data deduplication technology. The technology can eliminate redundant data and save storage space, on the other hand, the same data is no longer uploaded for remote data transfer, which can speed up the transmission.

Uit that cloud storage services behave in two different ways: first, through the Internet, for personal end users to provide storage services, this has become popular in Europe and America; second, the enterprise can also implement cloud storage services, through virtualization and other related technologies, the company's headquarters and branches together to form a virtual enterprise, Information that is dispersed across the enterprise can be uniformly protected and shared. Uit is trying to collaborate with some domestic telecom operators on cloud storage services. "Over the past two or three years, cloud storage has grown rapidly in the U.S. market, and Amazon has done very well," he said. "From 2009 onwards, cloud storage is likely to mature around the world," Cui said. ”
