ONTAP
ONTAP, Data ONTAP, Clustered Data ONTAP (cDOT), or Data ONTAP 7-Mode is NetApp's proprietary operating system used in storage disk arrays such as NetApp FAS and AFF, ONTAP Select, and Cloud Volumes ONTAP. With the release of version 9.0, NetApp decided to simplify the Data ONTAP name and removed the word "Data" from it, removed the 7-Mode image, therefore, ONTAP 9 is the successor of Clustered Data ONTAP 8. ONTAP includes code from BSD ''Net/2'' and ''4.4BSD-Lite'', Spinnaker Networks technology, and other operating systems. ONTAP originally only supported NFS, but later added support for Server Message Block, SMB, iSCSI, and Fibre Channel Protocol (including Fibre Channel over Ethernet and NVM Express#NVMeOF, FC-NVMe). On June 16, 2006, NetApp released two variants of Data ONTAP, namely Data ONTAP 7G and, with nearly a complete rewrite, Data ONTAP GX. Data ONTAP GX was based on grid technology acquired from Spinnaker Networks. In 2010 these software product lines merged into on ...

NetApp FAS
A NetApp FAS is a computer storage product by NetApp running the ONTAP operating system; the terms ONTAP, AFF, ASA, FAS are often used as synonyms. "Filer" is also used as a synonym although this is not an official name. There are three types of FAS systems: ''Hybrid'', ''All-Flash'', and ''All SAN Array'': # NetApp proprietary custom-build hardware appliances with HDD or SSD drives called hybrid Fabric-Attached Storage (or simply FAS) # NetApp proprietary custom-build hardware appliances with only SSD drives and optimized ONTAP for low latency called ALL-Flash FAS (or simply AFF) # All SAN Array build on top of AFF platform, and provide only SAN-based data protocol connectivity. ONTAP can serve storage over a network using file-based protocols such as NFS and SMB, also block-based protocols, such as the SCSI over the Fibre Channel Protocol on a Fibre Channel network, Fibre Channel over Ethernet (FCoE), iSCSI, and FC-NVMe transport layer. ONTAP-based systems that can serve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

FreeBSD
FreeBSD is a free-software Unix-like operating system descended from the Berkeley Software Distribution (BSD). The first version was released in 1993 developed from 386BSD, one of the first fully functional and free Unix clones on affordable home-class hardware, and has since continuously been the most commonly used BSD-derived operating system. FreeBSD maintains a complete system, delivering a kernel, device drivers, userland utilities, and documentation, as opposed to Linux only delivering a kernel and drivers, and relying on third-parties such as GNU for system software. The FreeBSD source code is generally released under a permissive BSD license, as opposed to the copyleft GPL used by Linux. The project includes a security team overseeing all software shipped in the base distribution. Third-party applications may be installed using the pkg package management system or from source via FreeBSD Ports. The project is supported and promoted by the FreeBSD Foundation ...

NVM Express
NVM Express (NVMe) or Non-Volatile Memory Host Controller Interface Specification (NVMHCIS) is an open, logical-device interface functional specification, specification for accessing a computer's non-volatile storage media usually attached via the PCI Express bus. The initial ''NVM'' stands for ''non-volatile memory'', which is often NAND flash memory that comes in several physical form factors, including solid-state drives (SSDs), PCIe add-in cards, and M.2 cards, the successor to mSATA cards. NVM Express, as a logical-device interface, has been designed to capitalize on the low Hard disk drive performance characteristics#Access time, latency and internal parallelism of solid-state storage devices. Architecturally, the logic for NVMe is physically stored within and executed by the NVMe controller chip that is physically co-located with the storage media, usually an SSD. Version changes for NVMe, e.g., 1.3 to 1.4, are incorporated within the storage media, and do not affect PCIe-c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PowerShell
PowerShell is a shell program developed by Microsoft for task automation and configuration management. As is typical for a shell, it provides a command-line interpreter for interactive use and a script interpreter for automation via a language defined for it. Originally only for Windows, known as Windows PowerShell, it was made open-source and cross-platform on August 18, 2016, with the introduction of PowerShell Core. The former is built on the .NET Framework; the latter on .NET (previously .NET Core). PowerShell is bundled with current versions of Windows and can be installed on macOS and Linux. Since Windows 10 build 14971, PowerShell replaced Command Prompt as the default command shell exposed by File Explorer. In PowerShell, administrative tasks are generally performed via ''cmdlets'' (pronounced ''command-lets''), which are specialized .NET classes implementing a particular operation. These work by accessing data in different data stores, like the file system ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISCSI
Internet Small Computer Systems Interface or iSCSI ( ) is an Internet Protocol-based storage networking standard for linking data storage facilities. iSCSI provides block-level access to storage devices by carrying SCSI commands over a TCP/IP network. iSCSI facilitates data transfers over intranets and to manage storage over long distances. It can be used to transmit data over local area networks (LANs), wide area networks (WANs), or the Internet and can enable location-independent data storage and retrieval. The protocol allows clients (called ''initiators'') to send SCSI commands (''CDBs'') to storage devices (''targets'') on remote servers. It is a storage area network (SAN) protocol, allowing organizations to consolidate storage into storage arrays while providing clients (such as database and web servers) with the illusion of locally attached SCSI disks. It mainly competes with Fibre Channel, but unlike traditional Fibre Channel which usually requires dedicated cabling ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fibre Channel Protocol
Fibre Channel Protocol (FCP) is the SCSI interface protocol utilising an underlying Fibre Channel connection. The Fibre Channel standards define a high-speed data transfer mechanism that can be used to connect workstations, mainframes, supercomputers, storage devices and displays. FCP addresses the need for very fast transfers of large volumes of information and could relieve system manufacturers from the burden of supporting a variety of channels and networks, as it provides one standard for networking, storage and data transfer. Some Fibre Channel characteristics are: *Performance from 266 megabits/second to 16 gigabits/second *Support both optical and copper media, with distances up to 10 km. * Small connectors ( sfp+ are most common) * High-bandwidth utilisation with distance insensitivity * Support for multiple cost/performance levels, from small systems to supercomputers * Ability to carry multiple existing interface command sets, including Internet Protocol (IP), S ...

Fibre Channel Over Ethernet
Fibre Channel over Ethernet (FCoE) is a computer network technology that encapsulates Fibre Channel frames over Ethernet networks. This allows Fibre Channel to use 10 Gigabit Ethernet networks (or higher speeds) while preserving the Fibre Channel protocol. The specification was part of the International Committee for Information Technology Standards T11 FC-BB-5 standard published in 2009. FCoE did not see widespread adoption. Functionality FCoE transports Fibre Channel directly over Ethernet while being independent of the Ethernet forwarding scheme. The FCoE protocol specification replaces the FC0 and FC1 layers of the Fibre Channel stack with Ethernet. By retaining the native Fibre Channel constructs, FCoE was meant to integrate with existing Fibre Channel networks and management software. Traditionally, data centers used both Ethernet for TCP/IP networks and Fibre Channel for SANs, each having different and mostly incompatible interfaces/connections and interconnects/wiri ...

Proprietary Software
Proprietary software is computer software, software that grants its creator, publisher, or other rightsholder or rightsholder partner a legal monopoly by modern copyright and intellectual property law to exclude the recipient from freely sharing the software or modifying it, and—in some cases, as is the case with some patent-encumbered and EULA-bound software—from making use of the software on their own, thereby restricting their freedoms. Proprietary software is a subset of non-free software, a term defined in contrast to free and open-source software; non-commercial licenses such as CC BY-NC are not deemed proprietary, but are non-free. Proprietary software may either be closed-source software or source-available software. Types Origin Until the late 1960s, computers—especially large and expensive mainframe computers, machines in specially air-conditioned computer rooms—were usually leased to customers rather than Sales, sold. Service and all software available ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unix-like
A Unix-like (sometimes referred to as UN*X, *nix or *NIX) operating system is one that behaves in a manner similar to a Unix system, although not necessarily conforming to or being certified to any version of the Single UNIX Specification. A Unix-like Application software, application is one that behaves like the corresponding List of POSIX commands, Unix command or Unix shell, shell. Although there are general Unix philosophy, philosophies for Unix design, there is no technical standard defining the term, and opinions can differ about the degree to which a particular operating system or application is Unix-like. Some well-known examples of Unix-like operating systems include Linux, FreeBSD and OpenBSD. These systems are often used on servers as well as on personal computers and other devices. Many popular applications, such as the Apache HTTP Server, Apache web server and the Bash (Unix shell), Bash shell, are also designed to be used on Unix-like systems. Definition The Open ...

Non-volatile Random-access Memory
Non-volatile random-access memory (NVRAM) is random-access memory that retains data without applied power. This is in contrast to dynamic random-access memory (DRAM) and static random-access memory (SRAM), which both maintain data only for as long as power is applied, or forms of Sequential access memory, sequential-access memory such as magnetic tape, which cannot be randomly accessed but which retains data indefinitely without electric power. Read-only memory devices can be used to store system firmware in embedded systems such as an automotive ignition system control or home appliance. They are also used to hold the initial processor instructions required to Bootstrapping, bootstrap a computer system. Read-write memory such as NVRAM can be used to store calibration constants, passwords, or setup information, and may be integrated into a microcontroller. If the main memory of a computer system were non-volatile, it would greatly reduce the time required to start a system afte ...
