Universal Storage Platform
Universal Storage Platform (USP) was the brand name for an Hitachi Data Systems line of computer data storage disk arrays circa 2004 to 2010. History The Hitachi Universal Storage Platform was first introduced in 2004. An entry-level enterprise and high-end midrange model, the Network Storage Controller was introduced in 2005. The Universal Storage Platform was one of the first disk arrays to virtualize other disk arrays in the appliance instead of in the network. The second generation Universal Storage Platform V replaced the original Universal Storage Platform in 2007 and the Universal Storage Platform VM replacing the original Network Storage Controller also in 2007. Architecture At the core of the Universal Storage Platform V and VM is a fully fault tolerant, high performance, non-blocking, silicon based switched architecture designed to provide the bandwidth needed to support infrastructure consolidation of enterprise file and block-based storage services on and beh ...

Storage Server
In computing, a file server (or fileserver) is a computer attached to a network that provides a location for shared disk access, i.e. storage of computer files (such as text, image, sound, video) that can be accessed by workstations within a computer network. The term server highlights the role of the machine in the traditional client–server scheme, where the clients are the workstations using the storage. A file server does not normally perform computational tasks or run programs on behalf of its client workstations (in other words, it is different from e.g. an application server, which is another type of server). File servers are commonly found in schools and offices, where users use a local area network to connect their client computers. Types of file servers A file server may be dedicated or non-dedicated. A dedicated server is designed specifically for use as a file server, with workstations attached for reading and writing files and databases. File servers may also be ...

Hitachi Data Systems
Hitachi Data Systems (HDS) was a provider of modular mid-range and high-end computer data storage systems, software, and services. Its operations are now a part of Hitachi Vantara. In 2010, Hitachi Data Systems sold through direct and indirect channels in more than 170 countries and regions, with customers that included over half of the Fortune 100 companies at the time. It was a subsidiary of Hitachi and part of the Hitachi Information Systems & Telecommunications Division until 2017. In 2017, it merged with Pentaho and Hitachi Insight Group to form Hitachi Vantara. History Origin as Itel Itel was founded in 1967 by Peter Redfield and Gary Friedman as an equipment leasing company and initially focused on leasing IBM mainframes. Through creative financial arrangements and investments, Itel began to lease IBM mainframes to customers at lower costs, which led to Itel ranking second to IBM in revenues. In 1977, a joint venture between National Semiconductor and Hitachi formed ...

Virtual Storage Platform
Virtual Storage Platform (VSP) is the brand name for a Hitachi Data Systems line of computer data storage systems for data centers. Model numbers include G200, G400, G600, G800, G1000, G1500 and G5500 History Hitachi Virtual Storage Platform, also known as VSP was first introduced in September, 2010. This storage platform builds on the design of Universal Storage Platform V, originally released in 2007. Architecture At the heart of the system is the HiStar E-Network, a network crossbar switch matrix. This storage platform is made up of different technologies than USP and USP V. The connectivity to back-end disks is via 6 Gbit/s SAS links instead of 4 Gbit/s Fibre Channel loop. The internal processors are now Intel multi-core processors, and in addition to 3.5-inch drives support has been added for 2.5 inch small-form factor HDDs. The VSP supports SSD, SAS and SATA drives. Features included: *The ability for growth in three ways: ** Scale up to meet increas ...

Computer Data Storage
Computer data storage or digital data storage is a technology consisting of computer components and Data storage, recording media that are used to retain digital data. It is a core function and fundamental component of computers. The central processing unit (CPU) of a computer is what manipulates data by performing computations. In practice, almost all computers use a storage hierarchy, which puts fast but expensive and small storage options close to the CPU and slower but less expensive and larger options further away. Generally, the fast technologies are referred to as "memory", while slower persistent technologies are referred to as "storage". Even the first computer designs, Charles Babbage's Analytical Engine and Percy Ludgate's Analytical Machine, clearly distinguished between processing and memory (Babbage stored numbers as rotations of gears, while Ludgate stored numbers as displacements of rods in shuttles). This distinction was extended in the Von Neumann archite ...

Disk Array
A disk array is a disk storage system which contains multiple disk drives. It is differentiated from a disk enclosure, in that an array has cache (computing), cache memory and advanced functionality, like redundant array of independent disks, RAID, Data deduplication, deduplication, encryption and Storage virtualization, virtualization. Components of a disk array include: * Disk array controllers * Cache (computing), Cache in form of both volatile random-access memory and Non-volatile memory, non-volatile flash memory. * Disk enclosures for both Magnetic storage, magnetic rotational hard disk drives and electronic solid-state drives. * Power supply, Power supplies Typically a disk array provides increased availability, resiliency, and maintainability by using additional redundant components (controllers, power supplies, fans, etc.), often up to the point where all single point of failure, single points of failure (SPOFs) are eliminated from the design. Additionally, disk array com ...

Storage Virtualization
In computer science, storage virtualization is "the process of presenting a logical view of the physical storage resources to" a host computer system, "treating all storage media (hard disk, optical disk, tape, etc.) in the enterprise as a single pool of storage." A "storage system" is also known as a storage array, disk array, or ''filer''. Storage systems typically use special hardware and software along with disk drives in order to provide very fast and reliable storage for computing and data processing. Storage systems are complex, and may be thought of as a special purpose computer designed to provide storage capacity along with advanced data protection features. Disk drives are only one element within a storage system, along with hardware and special purpose embedded software within the system. Storage systems can provide either block accessed storage, or file accessed storage. Block access is typically delivered over Fibre Channel, iSCSI, SAS, FICON or other prot ...

Thin Provisioning
In computing, thin provisioning involves using virtualization technology to give the appearance of having more physical resources than are actually available. If a system always has enough resource to simultaneously support all of the virtualized resources, then it is not thin provisioned. The term thin provisioning is applied to disk layer in this article, but could refer to an allocation scheme for any resource. For example, real memory in a computer is typically thin-provisioned to running tasks with some form of address translation technology doing the virtualization. Each task acts as if it has real memory allocated. The sum of the allocated virtual memory assigned to tasks typically exceeds the total of real memory. The efficiency of thin or thick/fat provisioning is a function of the use case, not of the technology. Thick provisioning is typically more efficient when the amount of resource used very closely approximates to the amount of resource allocated. Thin provisio ...
