IBM Tivoli Storage Manager
IBM Spectrum Protect (Tivoli Storage Manager) is a data protection platform that gives enterprises a single point of control and administration for backup and recovery. It is the flagship product in the IBM Spectrum Protect (Tivoli Storage Manager) family. It enables backups and recovery for virtual, physical and cloud environments of all sizes. This product is part of the IBM Spectrum Software Defined Storage suite of products and is unrelated to the Tivoli Management Framework. History TSM descended from a project done at IBM's Almaden Research Center around 1988 to back up VM/CMS systems. The first product that emerged was ''Workstation Data Save Facility'' (WDSF). WDSF's original purpose was to back up PC/DOS, OS/2, and AIX workstation data onto a VM/CMS (and later MVS) server. WDSF morphed into ''ADSTAR Distributed Storage Manager'' (ADSM) and was re-branded Tivoli Storage Manager in 1999. The TSM database (through release 5.5) was a bespoke B+ tree database; al ...

Cross-platform
In computing, cross-platform software (also called multi-platform software, platform-agnostic software, or platform-independent software) is computer software that is designed to work in several computing platforms. Some cross-platform software requires a separate build for each platform, but some can be directly run on any platform without special preparation, being written in an interpreted language or compiled to portable bytecode for which the interpreters or run-time packages are common or standard components of all supported platforms. For example, a cross-platform application may run on Microsoft Windows, Linux, and macOS. Cross-platform software may run on many platforms, or as few as two. Some frameworks for cross-platform development are Codename One, Kivy, Qt, Flutter, NativeScript, Xamarin, Phonegap, Ionic, and React Native. Platforms ''Platform'' can refer to the type of processor (CPU) or other hardware on which an operating system (OS) or application runs ...

DMAPI
Data Management API (DMAPI) is the interface defined in the X/Open document "Systems Management: Data Storage Management (XDSM) API" dated February 1997. XFS, IBM JFS, VxFS, AdvFS, StorNext and IBM Spectrum Scale file systems support DMAPI for Hierarchical Storage Management Hierarchical storage management (HSM), also known as Tiered storage, is a data storage and Data management technique that automatically moves data between high-cost and low-cost storage media.

FlashCopy Manager
FlashCopy is an IBM feature supported on various IBM storage devices that made it possible to create, nearly instantaneously, point-in-time snapshot copies of entire logical volumes or data sets. The Hitachi Data Systems implementation providing similar function was branded as ShadowImage. Using either implementation, the copies are immediately available for both read and write access. Implementations Version 1 The first implementation of FlashCopy, Version 1 allowed entire volumes to be instantaneously “copied” to another volume by using the facilities of the newer Enterprise Storage Subsystems (ESS). Version 1 of FlashCopy had limitations however. Although the copy or “flash” of a volume occurred instantaneously, the FlashCopy commands were issued sequentially and the ESS required a brief moment to establish the new pointers. Because of this minute processing delay, the data residing on two volumes that were FlashCopied are not exactly time consistent. Version 2 FlashC ...

Snapshot (computer Storage)
In computer systems, a snapshot is the state of a system at a particular point in time. The term was coined as an analogy to that in photography. It can refer to an actual copy of the state of a system or to a capability provided by certain systems. Rationale A full backup of a large data set may take a long time to complete. On multi-tasking or multi-user systems, there may be writes to that data while it is being backed up. This prevents the backup from being atomic and introduces a version skew that may result in data corruption. For example, if a user moves a file into a directory that has already been backed up, then that file would be completely missing on the backup media, since the backup operation had already taken place before the addition of the file. Version skew may also cause corruption with files which change their size or contents underfoot while being read. One approach to safely backing up live data is to temporarily disable write access to data during th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

NetApp Filer
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] |
Network Attached Storage
Network-attached storage (NAS) is a file-level (as opposed to block-level storage) computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. The term "NAS" can refer to both the technology and systems involved, or a specialized device built for such functionality (as unlike tangentially related technologies such as local area networks, a NAS device is often a singular unit). A NAS device is optimised for serving files either by its hardware, software, or configuration. It is often manufactured as a computer appliance a purpose-built specialized computer. NAS systems are networked appliances that contain one or more storage drives, often arranged into logical, redundant storage containers or RAID. Network-attached storage typically provide access to files using network file sharing protocols such as NFS, SMB, or AFP. From the mid-1990s, NAS devices began gaining popularity as a convenient method of sharing files a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NDMP
NDMP, or Network Data Management Protocol, is a protocol meant to transport data between network attached storage (NAS) devices and backup devices. This removes the need for transporting the data through the backup server itself, thus enhancing speed and removing load from the backup server. It was originally invented by NetApp and Intelliguard, acquired by Legato and then EMC Corporation. Currently, the Storage Networking Industry Association (SNIA) oversees the development of the protocol. Most contemporary multi-platform backup software Backup software are computer programs used to perform a backup; they create supplementary exact copies of files, databases or entire computers. These programs may later use the supplementary copies to restore the original contents in the event of d ... support this protocol.

Infiniband
InfiniBand (IB) is a computer networking communications standard used in high-performance computing that features very high throughput and very low latency. It is used for data interconnect both among and within computers. InfiniBand is also used as either a direct or switched interconnect between servers and storage systems, as well as an interconnect between storage systems. It is designed to be scalable and uses a switched fabric network topology. By 2014, it was the most commonly used interconnect in the TOP500 list of supercomputers, until about 2016. Mellanox (acquired by Nvidia) manufactures InfiniBand host bus adapters and network switches, which are used by large computer system and database vendors in their product lines. As a computer cluster interconnect, IB competes with Ethernet, Fibre Channel, and Intel Omni-Path. The technology is promoted by the InfiniBand Trade Association. History InfiniBand originated in 1999 from the merger of two competing designs: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
