Storage virtualizationProviding to a computer system a logical view of physical storage 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.
Disk storageDisk storage (also sometimes called drive storage) is a data storage mechanism based on a rotating disk. The recording employs various electronic, magnetic, optical, or mechanical changes to the disk's surface layer. A disk drive is a device implementing such a storage mechanism.
Single point of failureA single point of failure (SPOF) is a part of a system that would stop the entire system from working if it were to fail. The term single point of failure implies that there is no backup or redundant option that would enable the system to continue to function without it. SPOFs are undesirable in any system with a goal of high availability or reliability, be it a business practice, software application, or other industrial system.
Cache (computing)In computing, a cache ( ) is a hardware or software component that stores data so that future requests for that data can be served faster; the data stored in a cache might be the result of an earlier computation or a copy of data stored elsewhere. A cache hit occurs when the requested data can be found in a cache, while a cache miss occurs when it cannot.
Data deduplicationIn computing, data deduplication is a technique for eliminating duplicate copies of repeating data. Successful implementation of the technique can improve storage utilization, which may in turn lower capital expenditure by reducing the overall amount of storage media required to meet storage capacity needs. It can also be applied to network data transfers to reduce the number of bytes that must be sent.Disk enclosureA disk enclosure or desktop hard drive is a specialized casing designed to hold and power hard disk drives or solid-state drives while providing a mechanism to allow them to communicate to one or more separate computers. Drive enclosures provide power to the drives therein and convert the data sent across their native data bus into a format usable by an external connection on the computer to which it is connected.Hot swappingHot swapping is the replacement or addition of components to a computer system without stopping, shutting down, or rebooting the system. Hot plugging describes only the addition of components to a running computer system. Components which have such functionality are said to be hot-swappable or hot-pluggable; likewise, components which do not are cold-swappable or cold-pluggable.
DataDirect NetworksDataDirect Networks (DDN) is a privately held data storage company, and is headquartered in Chatsworth, California, USA. SummaryDDN provides storage systems for unstructured data and big data, like AI, analytics and high performance computing (HPC) environments, in enterprise, government and academia sectors. Although privately held, DDN announced that it had achieved annual revenue of $400 million and its highest profitability in 2020.
Coraid, Inc.Coraid, Inc. is a computer data storage vendor that provides storage area network (SAN) products that use Ethernet, headquartered in Athens, Georgia. HistoryThe company was founded by Brantley Coile, who previously worked on the Cisco PIX firewall and Cisco LocalDirector products.
EncryptionIn cryptography, encryption is the process of transforming information in a way that, ideally, only authorized parties can decode. This process converts the original representation of the information, known as plaintext, into an alternative form known as ciphertext. Encryption does not itself prevent interference but denies the intelligible content to a would-be interceptor.
RAIDRAID (Redundant Array of Independent Disks) is an orchestrated approach to computer data storage in which data is written to more than one secondary storage device. Instead of storing all data in a single hard disk drive or solid-state drive, RAID coordinates two or more such devices into a disk array. When the computer writes data to secondary storage, the RAID system distributes the data across the array.
EMC CorporationEMC Corporation (stylized as EMC²) was an American multinational corporation headquartered in Hopkinton, Massachusetts, which sold data storage, information security, virtualization, analytics, cloud computing and other products and services that enabled organizations to store, manage, protect, and analyze data. EMC's target markets included large companies and small- and medium-sized businesses across various vertical markets.*As an Amazon Associate I earn from qualifying purchases.
