Commodity Storage
Data storage is a specialized technical system for electronic data storage.
The data warehouse consists of the following components:
The data storage facility defines the requirements for the storage facility ' s hardware and software and thus forms the basis for the classification of data warehouses.
The lecture will address the following issues related to data carriers and repositories:
Types of data carriers
Main types of physical hosts used for data storage:
Magnetic discs (HDD, Hard Disk Drive)
Main data storage reservoir. The possibility of merging both external and internal, hot replacement of launchers in the mass. The changeable host is in its essence, so it is ideal for the rapid storage of any type of data.
Perfect for ongoing work and rapid data storage.
Optical disk (MO, DVD)
CDs in this course are not regarded as derogating DVD on any parameters in the archival storage tasks.
When used in robotic reservoirs, it is ideal for long-term archival storage of large quantities of data (fail, e-mail, Oracle read-only tablespaces) and for the expansion of hard drives and volumes. The physical properties of these launchers, as well as the mechanisms for monitoring the recording and diagnosis of the state of optical disk, ensure the safe storage of valuable data for decades.
Use of single-record technology with data protection from disposal and modification
