Hierarchical storage management (HSM), also known as tiered storage, [1] is a data storage and data management technique that automatically moves data between high-cost and low-cost storage media. HSM systems exist because high-speed storage devices, such as solid-state drive arrays, are more expensive (per byte stored) than slower devices ...
Minidisks can correspond to physical disk drives, but more typically refer to logical drives, which are mapped automatically onto shared devices by the operating system as sets of virtual cylinders. CP/CMS inspired numerous other operating systems, including the CP/M microcomputer operating system, which uses a drive letter to specify a ...
VTOC (Volume Table Of Contents) - Data structure on IBM mainframe direct-access storage devices (DASD) such as disk drives that provides a way of locating the data sets that reside on the DASD volume. XFS – Used on SGI IRIX and Linux systems; zFS – z/OS File System; not to be confused with other file systems named zFS or ZFS.
The CP/M operating system uses a flat file system, with a directory containing information on a maximum of 64 files—adequate when a floppy disk held only 128 KB. IBM PC DOS and MS-DOS 1.0 inherited the same structure. DOS 2.0, which supported hard disk drives, introduced a hierarchical file system. The hierarchical file system was used ...
DiskStation Manager (DSM) is a Linux-based operating system developed by Synology for its NAS products. Synology's software architecture allows for third-party add-on application integration. Hundreds of third-party applications are available in addition to Synology's own catalog. Command line access via SSH or Telnet is available.
Amazon S3 Glacier is an online file storage web service that provides storage for data archiving and backup. [ 2 ] Glacier is part of the Amazon Web Services suite of cloud computing services, and is designed for long-term storage of data that is infrequently accessed and for which retrieval latency times of 3 to 5 hours are acceptable.
In computer architecture, the memory hierarchy separates computer storage into a hierarchy based on response time. Since response time, complexity , and capacity are related, the levels may also be distinguished by their performance and controlling technologies. [ 1 ]
Essential system binaries (e.g., fsck, init, route). /srv: Site-specific data served by this system, such as data and scripts for web servers, data offered by FTP servers, and repositories for version control systems (appeared in FHS-2.3 in 2004). /sys: Contains information about devices, drivers, and some kernel features.
