IPI (Intelligent Peripheral Interface)

IPI (Intelligent Peripheral Interface) IPI (Intelligent Peripheral Interface) is a high-bandwidth interface between a computer and a hard disk or a tape device. Devices using IPI can transfer data between the hard drive and RAM in the range between 3 and 25 megabytes per second.The latest version of IPI is IPI-3, which supports redundant array of independent disks. The official IPI standards are: ANSI/ISO 9318-3 Intelligent Peripheral Interface - Device Generic Command Set for Magnetic...

SSD (solid-state drive) Definition

SSD (solid-state drive) Definition An SSD (solid-state drive) is a type of nonvolatile storage media that stores persistent data on solid-state flash memory. Two key components make up an SSD: a flash controller and NAND flash memory chips. The architectural configuration of the SSD controller is optimized to deliver high read and write performance for both sequential and random data requests. SSDs are sometimes referred to as flash drives or solid-state disks. Unlike a hard disk dri...

Multisession CD Definition

Multisession CD Definition A multisession CD is a recordable CD format (like a CD-R) that allows the recording of a compact disk to be conducted in more than one recording session. If there is free space left on the CD after the first session, additional data can be written to it at a later date. Each session has its own lead in, program area, and lead out. This takes up about 20 megabytes of space, and therefore, is less efficient than recording data all at once. Multisession CDs ...

Optical Media Definition

Optical Media Definition Optical media - such as the compact disk (CD) - are storage media that hold content in digital form and that are written and read by a laser; these media include all the various CD and DVD variations, as well as optical jukeboxes and autochangers. Optical media have a number of advantages over magnetic media such as the floppy disk. Optical disk capacity ranges up to 6 gigabytes; that's 6 billion bytes compared to the 1.44 megabytes (MB) - 1,440,000 bytes - of the flo...

WORM (write once, read many) Definition

WORM (write once, read many) Definition In computer storage media, WORM (write once, read many) is a data storage technology that allows information to be written to a disc a single time and prevents the drive from erasing the data. The discs are intentionally not rewritable, because they are especially intended to store data that the user does not want to erase accidentally. Because of this feature, WORM devices have long been used for the archival purposes of organizations such as governm...

Common Internet File System (CIFS)

Common Internet File System (CIFS) Common Internet File System (CIFS): Short for Common Internet File System, a protocol that defines a standard for remote file access using millions of computers at a time. With CIFS, users with different platforms and computers can share files without having to install new software. CIFS runs over TCP/IP but uses the SMB (Server Message Block)protocol found in Microsoft Windows for file and printer access; therefore, CIFS will allow all applications, no...

Direct-Attached Storage (DAS)

Direct-Attached Storage (DAS) Stands for "Direct Attached Storage." DAS refers to any storage device connected directly to a computer. Examples include HDDs, SSDs, and optical drives. While DAS can refer to internal storage devices, it is most often describes external devices, such as an external hard drive. The term "DAS" was created to differentiate between network-attached storage (NAS) and direct-attached storage. Before NAS and storage area networks (SANs) were available, direct-att...

Network-Attached Storage (NAS)

Network-Attached Storage (NAS)       Network-attached storage (NAS) is a type of dedicated file storage device that provides local-area network local area network (LAN) nodes with file-based shared storagethrough a standard Ethernet connection. NAS devices, which typically do not have a keyboard or display, are configured and managed with a browser-based utility program. Each NAS resides on the LAN as an independent network node and has its own IP address. Netgea...

Storage Provisioning

Storage Provisioning Storage provisioning is the process of assigning storage, usually in the form of server disk drive space, in order to optimize the performance of a storage area network (SAN). Traditionally, this has been done by the SAN administrator, and it can be a tedious process.Storage provisioning is done in steps, which must be followed in a specific order. The storage must be configured for optimum SAN performance. Logical unit numbers (LUNs) must be assigned within the net...

Software-Defined Storage SDS

Software-Defined Storage SDS Software-Defined Storage SDS: Storage infrastructure that is managed and automated by intelligent software as opposed to by the storage hardware itself. In this way, the pooled storage infrastructure resources in a software-defined storage (SDS) environment can be automatically and efficiently allocated to match the application needs of an enterprise. Separating the Storage Hardware from the Software By separating the storage hardware from the software that ma...
