A large tape library, with tape cartridges placed on shelves in the front, and a robotic arm moving in the back.Visible height of the library is about 180 cm. The nearline storage system knows on which volume (cartridge) the data resides, and usually asks a robot to retrieve it from this physical location (usually: a tape library or optical jukebox) and put it into a tape drive or optical disc ...
Off-line bulk storage – Tertiary and Off-line storage. This is a general memory hierarchy structuring. Many other structures are useful. For example, a paging algorithm may be considered as a level for virtual memory when designing a computer architecture, and one can include a level of nearline storage between online and offline storage.
Computer data storage or digital data storage is a technology consisting of computer components and recording media that are used to retain digital data. It is a core function and fundamental component of computers. [1]: 15–16 The central processing unit (CPU) of a computer is what manipulates data by performing computations.
The four classes, Multi-Regional Storage, Regional Storage, Nearline Storage, and Coldline Storage, differ in their pricing, minimum storage durations, and availability. [5] Interoperability - Google Cloud Storage is interoperable with other cloud storage tools and libraries that work with services such as Amazon S3 and Eucalyptus Systems. [6]
Nearline storage is typically less accessible and less expensive than online storage, but still useful for backup data storage. A mechanical device is usually used to move media units from storage into a drive where the data can be read or written. Generally it has safety properties similar to on-line storage.
MAID (massive array of idle drives) is an architecture using hundreds to thousands of hard drives for providing nearline storage of data. MAID is designed for write once, read occasionally (WORO) applications. [14] [15] [16] Compared to RAID technology, MAID has increased storage density, and decreased cost, electrical power, and cooling ...
