Block virtualization used in this context refers to the abstraction (separation) of logical storage (partition) from physical storage so that it may be accessed without regard to physical storage or heterogeneous structure. This separation allows the administrators of the storage system greater flexibility in how they manage storage for end users.
software-defined storage (SDS), which includes storage virtualization, suggests a service interface to provision capacity and SLAs (Service Level Agreements) for storage, including performance and durability; management and automation software, enabling an administrator to provision, control, and manage all software-defined data-center ...
Health information technology (HIT) is "the application of information processing involving both computer hardware and software that deals with the storage, retrieval, sharing, and use of health care information, health data, and knowledge for communication and decision making". [8]
Data virtualization is an approach to data management that allows an application to retrieve and manipulate data without requiring technical details about the data, such as how it is formatted at source, or where it is physically located, [1] and can provide a single customer view (or single view of any other entity) of the overall data.
A VTL presents a storage component (usually hard disk storage) as tape libraries or tape drives for use with existing backup software. Virtualizing the disk storage as tape allows integration of VTLs with existing backup software and existing backup and recovery processes and policies. The benefits of such virtualization include storage ...
As with most other virtualization designs, "a primary driver behind file virtualization is the desire to shield users and administrators from the complexity of the underlying storage environment. Other goals include simplified management, more efficient capacity usage and allocation, and reduced management costs [ 1 ] ".
Cloud computing enables users to access scalable and on-demand computing resources via the internet, utilizing hardware and software virtualization. It is a rapidly evolving technology capable of delivering extensible services efficiently, supporting a wide range of applications from personal storage solutions to enterprise-level systems.
The primary difference between converged infrastructure and hyperconverged infrastructure is that in HCI both the storage area network and the underlying storage abstractions [clarification needed] are implemented virtually in software (at or via the hypervisor) rather than physically in hardware.
