Cloud Storage--The new blue Sea of telecom operators

Best Incubator platform for new telecom business

Cloud storage is a concept that extends and develops on the basis of cloud computing, refers to the use of cluster applications, grid technology or Distributed file system functions, the network of a large number of different types of storage devices, through the application software together to work together to provide data storage and business access functions of a system. When the core of cloud computing system operation and processing is large amount of data storage and management, cloud computing system needs to configure a large number of storage devices, then cloud computing system into a cloud storage system, so cloud storage is a data storage and management as the core of the cloud computing system. Let's look at what new services cloud storage can bring to operators.

Storage Resource Pool Leasing Service

Using cloud storage, you can build a storage space leasing service similar to Amazon S3, providing flexible storage services on demand for individuals and enterprise users. When users purchase storage resources on demand from a resource pool operator, they can access and use the storage resources through a web-based protocol without purchasing and transporting the storage devices. At the same time, the Multi-Tenant model can isolate data from different users to ensure data security for users.

Network Disk Application

On the basis of a large cloud storage resource pool, a graphical user interface (GUI) is used to encapsulate the object storage resources, which can provide the user with a network disk business similar to the drop box. Users can upload, download, manage and share data through PC client, mobile client and Web page. With the help of the network disk, personal and home users can achieve a lasting data storage and data synchronization between different terminals, enterprise users can achieve more efficient information sharing, collaborative office and unstructured data management, while the enterprise network disk can also achieve low-cost Windows Remote Backup to ensure enterprise data security.

Data backup Services

For enterprise users, cloud storage, combined with backup software, provides a more cost-effective, lower TCO centralized backup scenario. In contrast to backup scenarios such as the original tape library or virtual tape library, the De-duplication feature can help users reduce device purchases, and intelligent management features make backup systems unnecessary for immediate maintenance, reducing capex and opex; the huge throughput and online/ Near-line storage mode can effectively reduce RTO and RPO.

Archiving and tiered storage

With archiving software, tiered storage software, cloud storage can seamlessly archive/classify data in an online system to object storage and release online system storage resources. Object storage has nearly unlimited capacity, intelligent management capabilities, and can help users reduce the TCO of mass data archiving; object archiving uses active archive mode to enable archived data to be accessed on demand without long waiting and latency.

Based on the above 4 basic services, cloud storage can also derive rich applications such as business data automatic backup, home data synchronous sharing, mobile phone instant transmission, multi-screen access interaction and so on. One feature of these businesses and applications is that the business experience is associated with a strong data transfer speed. In other words, only in the High-quality network support, these businesses can bring users a quality experience, and the core advantages of telecom operators in the network quality. Therefore, cloud storage will undoubtedly become the optimal platform for operators to exert innate advantages, develop new markets and realize business transformation.

UDs Innovation Concept

The advantages of cloud storage for operators are self-evident, so what should be paid attention to in the choice of cloud storage platform? The industry generally believes that the cloud storage platform should meet the requirements of massive business data capacity, while ensuring data security and reliability.

Huawei released the cloud-oriented uds (Universal distributed Storage) mass storage System in 2012, with an endless, secure, and trusted storage concept, with an innovative technology architecture that delivers high reliability, high scalability, and low-cost mass storage solutions. The scheme adopts a new smartdisk design concept, and in the storage industry, it first adopts a central architecture to establish a multi-level data protection system.

Skillfully constructing the basic--DHT ring technology

It is predicted that the total amount of human storage data will double every two years between now and 2020, so in order to maximize the protection of investment and maintain continuity of business development, operators must carefully consider the capacity expansion of the platform before choosing a cloud storage platform. UDs are based on DHT (distributed hash Table, distributed hashing algorithm), the address space of all storage units are partitioned and unified to map to the DHT ring, each storage cell partition is responsible for a small range of address space routing, and is responsible for storing a small number of data. Thus, the reading and writing of each object can be addressed to the corresponding storage unit partition at a time by hashing, thus enabling the entire system to be addressed and stored.

Because the address space of DHT ring is close to infinity, it can make the DHT ring scalable by the partition size adjustment and even partition number fission, which can theoretically support the infinite increase of the storage unit, and construct the foundation of EB-level capacity expansion.

Go to the centralized architecture--full peer Peer-to-peer access to reduce node indexing query delay

With the increase of capacity, the delay of querying data of traditional storage system is gradually exposed. A uds with an innovative architecture solves this problem well. The uds is logically divided into two main tiers, namely, the control node cluster and the storage node cluster. The control node is the access point of object Storage Service, the main functions include processing client request, establishing object transmission channel, realizing access control to client request, managing meta data. Storage nodes realize data and metadata storage, replication, consistency and other functions.

Under the DHT algorithm rule, the UDs control node cluster and storage node cluster, all Peer-to-peer data access is presented, that is, the control node can address the storage node directly and read and write the data, there is no central node in the traditional storage architecture in the system, which reduces the indexing query delay and avoids the corresponding bottleneck problem.

Smart hard disk--------realize node-level granular capacity expansion, throughput linear growth with capacity

With the new business on the line, the cloud storage platform will be in a continuous expansion of the state, and the expansion of the size of the carrier will have a significant impact on the cost of construction. The UDs storage node is also known as the smart hard disk, which consists of a single hard drive plus a low-power arm chip, a small capacity memory, and an Ethernet interface. Each smart hard disk with a separate IP address access to the switch, the composition of a distributed full cross-internet, by increasing the number of smart hard disk can achieve the most fine-grained size of the disk expansion.

Because each intelligent hard disk provides the established access throughput, the total throughput of the system will increase linearly with the expansion of the capacity, which can help the operators to achieve the perfect match between business and investment.

Multi-data centers to unify resource pools across geographies and improve operational performance

For business near line, geographical disaster and other aspects of consideration, multiple data centers are operators generally adopted the layout and strategy. UDs supports multiple data centers across geographically unified scheduling and flexible management, from TB to EB-level on-demand capacity to meet the different needs of users of different sizes.

In the case of multi data Center deployment, the system can support cross-regional synchronization, replica number strategy with flexible customization with SLA and the nearest access service, and further consolidate the construction, deployment and application of EB-level mass storage system from scalability, reliability and operational dimensions.

Huawei is based on scalable, one-address DHT ring algorithm technology, through the central architecture, intelligent hard disk interconnection technology, stateless control node cluster technology, metadata hashing storage technology, multi-data center, cross-regional deployment technology, such as accumulate thick builder, Build the UDs, a massive object storage infrastructure platform that can easily be extended to EB-level capacity.

UDs mass Storage System can provide users with on-demand storage capacity, and scalable to achieve high scalability, for the initial volume of business users, the choice of uds can reduce the initial cost of input, while reserving the business to flourish when the system smooth expansion capacity. For users running multiple business systems that require large storage capacity, choosing a uds can serve the business system in the form of a mass storage resource pool, effectively reducing TCO.
