A ramble on the technology of virtualization

With the extensive deployment of multi-core systems, clusters, grids and even cloud computing in recent years, virtualization technology has become more and more advantageous in business applications, not only reducing it costs, but also enhancing system security and reliability, and the concept of virtualization has gradually deepened into people's daily work and life. Aiming at the x86 platform, this paper first gives the basic concept and classification of virtualization technology, then expounds the realization principle and challenge of pure software virtualization, and finally introduces ...

Cloud Computing: Virtualization Technology (2)--Storage virtualization

Storage virtualization is spiraling upward as storage requirements grow, and the storage servers and arrays within the company multiply without exception. One solution to this storage-management dilemma is storage virtualization. Storage virtualization enables management programmers to identify, configure, and manage different storage as resources for a single collection.   Storage virtualization is an important part of storage consolidation that reduces management problems and improves storage utilization, which lowers the cost of new storage. Authoritative agency S N I A (Storage network industry association) gives ...

The composition and application of virtualization technology in deep analysis cloud storage

Storage Domain International Authority SNIa (Storage Network Industry Association) gives the definition of storage virtualization (Storagevirtualization): "By abstracting, hiding, or isolating the internal functions of the storage System/subsystem from applications, compute servers, network resources, Implement storage and data management independent of applications and networks. Storage virtualization technology is to abstract the underlying storage devices unified management, to the server layer to mask the specificity of storage equipment hardware, but only to retain their unified logic characteristics, so as to achieve the storage system ...

Virtualization Storage Interpretation

Compared with traditional storage, the advantages of virtualization storage are mainly reflected in: high disk utilization, traditional storage technology, disk utilization is generally only 30-70%, and the use of virtualization technology disk utilization up to 70-90%, storage flexibility, can adapt to different vendors, different types of heterogeneous storage platforms, Provides greater flexibility for storage resource management; Easy to manage, provides a centralized management of a large capacity storage system to avoid the management problems caused by the expansion of storage devices; better performance, virtualized storage systems can be well load-balanced, with each time data ...

Discussion on cloud security under the technology of virtualization

In recent years, cloud computing is a very popular research field, in fact, it is not a new technology, but a lot of technology integration, including distributed computing, dynamic and expansion of a variety of technology algorithms, and virtualization is the most important technology in cloud computing. Cloud security is a key and challenging issue in the development and application of cloud computing technology. Through the network of a large number of clients to Internet software behavior anomaly monitoring to obtain the Internet Trojan, malicious program of the latest information, pushed to the cloud server to automate the analysis and processing, and then the disease ...

Cloud computing provider Savvis Why "block-level storage"

Savvis uses compellent storage as a cloud storage platform in 28 global data center Enterprise cloud computing platforms, and Compellent's cloud storage configuration capacity reaches 3300TB. Compellent as the leader of "third generation" storage (block-level virtualization storage), its inherent resource virtualization advantage becomes the perfect choice for cloud storage platforms. Its advantages specific performance: ...

Performance comparison and tuning experience for Hadoop virtualization

Virtualization has injected unprecedented energy into Hadoop, from the perspective of it production management, as follows: · Deploying shared data centers with Hadoop and other applications that consume different types of resources increases overall resource utilization; • Flexible virtual machine operations enable users to dynamically create, expand their own Hadoop clusters based on datacenter resources, or reduce current clusters and release resources to support other applications if needed; With the HA, FT integration provided with the virtualization architecture, avoid ...

SME Server virtualization Deployment planning backup and disaster recovery

Server virtualization has gone deep into the mainstream of enterprise it. The efficiency and flexibility associated with virtualized server operations have been demonstrated many times in large enterprises. Server virtualization can increase server utilization, reduce power consumption, simplify it workload, and quickly meet changing business needs. More importantly, server virtualization enables organizations to run their applications to any qualified server, based on availability and actual need, without having to deliver the application to one or more servers. In other words, IT administrators can assign applications to ...

Virtio A common framework for I/O virtualization in a KVM virtual environment

Linux Kernel supports many Hypervisor, such as the KVM, Xen, and VMware VMI. Each Hypervisor has its own unique block, receptacle, console and other equipment models, device-driven diversification of the characteristics and optimization of the various platforms are less common, the need to provide a common framework and standard interface to reduce the Hypervisor The difference between virtualized devices, thereby reducing the burden of driving development. Virtual ...
