Three storage virtualization methods currently available storage virtualization is a collection of physical storage that aggregates multiple networked storage devices into one storage device, simplifying storage management. People are talking about the best way to implement storage virtualization, but there is no way to apply it to any environment. In fact, many companies use different architectural approaches based on specific requirements. You need to compare the various methods and then choose the appropriate storage virtualization approach to your needs. The following is a simple introduction to In-band, Out-of-band, and isolated path storage virtualization methods: In-band (In-b ...).

Cloud Terminal, the next generation PC called "Cloud Terminal", it no longer needs the central processing unit, hard disk, video card, even operating system and application software, because all of these functions are done by the public cloud server, it is a small set-top box, or directly built into the monitor. "The price is only 500 yuan." "Cloud terminal, not necessarily mobile device, this concept and notebook, netbook, tablet computer distinguish, they are not a class of devices, can not do comparisons." The future cloud terminal may be a sign of a signpost, dot ...

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 first thing to understand is that cloud computing is a concept that was put forward n years ago and is not a new technology. 　　Only over the years, Intel, IBM, HP and other IT producers have joined together to fire the concept of cloud computing. The core technology of cloud computing is virtualization, network virtualization, storage virtualization and so on. The current mainstream cloud platform such as Openstack,cloudstack,opennebula, they developed their own suite, through the Web browser, can easily manage virtualization, such as creating, deleting, cloning virtual ...

Since 2006, when Google introduced the concept of cloud computing, as a new technology and business model, the concept of divergent views. Various agencies and experts in related fields have defined cloud computing from different perspectives, such as some from the application scenario, and some from the resource angle. Among them, the September 2009 U.S. National Institute of Standards and Technology (NIST) proposed the definition of cloud computing, is very representative, has been widely accepted by the industry: "Cloud computing is a convenient access to a shared pool of resources, on-demand computing resources (these resources include network ...).
