Enterprise Data Center change: from cloud computing to cloud storage

Cloud storage products with the landing of the cloud, has been the support and attention of many vendors, cloud storage is the concept of cloud computing in the derivation and development of a new technology or services, cloud computing is distributed processing, parallel processing, network computing with each other, through the network to automatically split the computer processing program into No A number of smaller subroutines and a large system composed of multiple servers are calculated and analyzed to return the results to the user. Cloud storage is a system that brings together all kinds of storage devices in the network through the application software, and provides data storage and business access function externally.

What is cloud storage

Cloud storage is composed of 4 layers: storage layer, base management layer, application interface layer, Access layer.

The storage layer is the most basic part of cloud storage. Each storage device is connected by a variety of network devices, which can be FC Fibre Channel storage devices, IP storage devices such as NAS and iSCSI, or DAS storage devices such as SCSI or SAS. Above the storage device is a unified storage device management system, which can realize the logical virtualization management of storage devices, Multilink redundancy management, and the condition monitoring and fault maintenance of hardware devices.

The base management layer is the core part of cloud storage and the most difficult part of cloud storage. Through clustering, distributed file system and Grid computing, the basic management realizes the collaborative work among multiple storage devices in cloud storage, so that multiple storage devices can provide the same service externally, and provide greater and stronger data access performance. CDN Content distribution System, data encryption technology to ensure that the data in the cloud storage will not be accessed by unauthorized users, at the same time, through a variety of data backup and disaster-tolerant technology and measures to ensure that the data in the cloud storage will not be lost, to ensure the security and stability of the cloud storage.

Application interface layer: Different cloud storage operating units can develop different application service interfaces and provide different application services according to the actual business type. such as video surveillance application platform, IPTV and video-on-demand application platform, network hard disk reference platform, remote data backup application platform.

Access layer: Any authorized user can login to the cloud storage system through the standard common application interface and enjoy the cloud storage service. Cloud storage operates in different units, and cloud storage provides different types of access and means of access.

When the enterprise is deploying cloud storage, it must understand the following points

1. Whether to choose a private cloud or a public cloud

Like cloud computing, cloud storage also has a private cloud and public cloud, a common cloud that can store your information and run applications on the Internet, and private cloud, which has more flexibility, control, and security than the private cloud in the intranet.

2. Virtualization strategy for enterprise data centers

Cloud storage, like cloud computing, is built on virtualization, and when the enterprise determines the direction of implementation, it needs to deploy a more comprehensive virtualization strategy and select the most appropriate location for the datacenter. Virtual computing power and storage resources are key to making the cloud truly operational. The industry considers primarily virtualized servers, but it data centers also need virtualized storage, and implementing cloud computing on the server will greatly increase the enterprise's ability to do at the application level.

3. Must choose the best service according to the Enterprise's own point of reference

After the cloud is deployed in the enterprise's data center, it is necessary to choose the most economical way according to the Enterprise's own mode of operation. The advantage of a private cloud is deployment speed and security benefits, a private storage cloud built on virtualization technology that can be compatible with a variety of server and desktop virtualization platforms. If an enterprise needs to reduce risk, it can choose to apply it to a public cloud on a third-party company platform.

4. Enterprises Choose Storage Architecture choose to be cautious

Identify your company's data storage solution to meet the need for fast, unplanned data growth. Choose a storage architecture that allows for a reasonable and orderly increase or decrease in any direction. First ask yourself: What do you need to add to the San? If not only to downtime, but also a lot of staff attention and maintenance. So, from this system, you may not have the best application value.

5. Enterprise three kinds of environment suitable for using cloud storage

First, determine whether there is such a correlation, that is, the cost of hardware and software upgrades and the system "unlimited" scalability is closely related. Be aware at this point: when the system's capabilities are limited, some architectures imply a staggering amount of certification fees. For example: Are you bothered by software license fees? When you have to increase the number of drives or storage arrays again, this practice has actually exceeded the marginal optimal cost.

Second, verify that the storage environment is online and the data is available during system maintenance or when hardware and software are reconfigured. including hardware and software, all storage systems may need to be upgraded at any time. When updating, be sure to know what impact it will have on the system.

Finally, if you select data and disaster backup products, such as automatic snapshot and replication. But to be reminded, beware of some hidden costs, such as bandwidth requirements. It may limit the number of snapshots or replication (that is, the capacity to change each time or the entire replication).

Cloud storage products for mainstream manufacturers

At present, many manufacturers have launched a cloud storage products, more famous is EMC's Atmos cloud storage infrastructure solution, Atmos is a policy-based management system that provides the ability to build different types of cloud storage, for example, to create two copies of files for non-paying users. and stored in different locations around the world, and for paid users to create 5~10 backups for storage, and to provide their access to files around the world with higher reliability and faster access. In software systems, Atmos includes data services, such as replication, data compression, and data de-duplication, to obtain hundreds of TB of hard disk storage space through inexpensive standard x86 servers. EMC promises that it has the ability to automatically configure new storage space and adapt to hardware failures. Also allows users to manage and read using Web service protocols. Currently there are three versions of Atmos, with system capacity of 120TB, 240TB, and 360TB, all based on x86 servers and support gigabit or 10GbE Ethernet connections.

For IBM, XIV is a new generation of storage products offered by IBM. It uses grid technology, which greatly improves the reliability of data, the scalability of capacity, and the manageability of the system. XIV is upgraded over traditional storage devices. It has a mass storage device + Large capacity file system + High throughput Internet Data access interface + Management system design features. XIV because of its unique design, so that it is born with a huge amount of storage capacity and strong scalability, to meet the needs of a variety of Web2.0 applications, is an ideal product to achieve cloud storage.

"XIV products with IBM Information Management, protection, archiving and other important functions, is the IBM information infrastructure and storage key components, but also IBM can redefine the concept of storage products." "IBM Systems and Technology division of Greater China Product Department general manager Hou said."
