Object storage (also known as object-based storage [1] or blob storage) is a computer data storage approach that manages data as "blobs" or "objects", as opposed to other storage architectures like file systems, which manage data as a file hierarchy, and block storage, which manages data as blocks within sectors and tracks. [2]
Amazon EBS (elastic block store) is an example of a cloud block store. [2] Cloud block-level storage will usually offer facilities such as replication for reliability, or backup services. [3] Block-level storage is in contrast to an object store or 'bucket store', such as Amazon S3 (simple storage service), or to a database. These operate at a ...
Distributed block storage is a computer data storage architecture that the data is stored in volumes (known as blocks, a term dating back to Project Stretch [1]) across multiple physical servers, as opposed to other storage architectures like file systems which manages data as a file hierarchy, and object storage which manages data as objects.
DBMSes often use their own block I/O for improved performance and recoverability as compared to layering the DBMS on top of a file system. On Linux the default block size for most file systems is 4096 bytes. The stat command part of GNU Core Utilities can be used to check the block size. In Rust a block can be read with the read_exact method. [6]
This shows the typical layout of a simple computer's program memory with the text, various data, and stack and heap sections. Historically, BSS (from Block Started by Symbol) is a pseudo-operation in UA-SAP (United Aircraft Symbolic Assembly Program), the assembler developed in the mid-1950s for the IBM 704 by Roy Nutt, Walter Ramshaw, and others at United Aircraft Corporation.
Ceph (pronounced / ˈ s ɛ f /) is a free and open-source software-defined storage platform that provides object storage, [7] block storage, and file storage built on a common distributed cluster foundation. Ceph provides distributed operation without a single point of failure and scalability to the exabyte level.
The term closure is often used as a synonym for anonymous function, though strictly, an anonymous function is a function literal without a name, while a closure is an instance of a function, a value, whose non-local variables have been bound either to values or to storage locations (depending on the language; see the lexical environment section below).
A cache is a storage for a specific type of object, such as semaphores, process descriptors, file objects, etc. Slab: slab represents a contiguous piece of memory, usually made of several virtually contiguous pages. The slab is the actual container of data associated with objects of the specific kind of the containing cache.
