Storage Efficiency
Storage efficiency is the ability to store and manage data that consumes the least amount of space with little to no impact on performance; resulting in a lower total operational cost. Efficiency addresses the real-world demands of managing costs, reducing complexity and limiting risk. The Storage Networking Industry Association (SNIA) defines storage efficiency in the SNIA Dictionary as follows: : \text = \frac. The efficiency of an empty enterprise level system is commonly in the 40–70% range, depending on what combination of RAID, mirroring and other data protection technologies are deployed, and may be even lower for highly redundant remotely mirrored systems. As data is stored on the system, technologies such as deduplication and compression may store data at a greater than 1-to-1 data size-to-space consumed ratio, and efficiency rises, often to over 100% for primary data, and thousands of percent for backup data. Technologies Different technologies exist at differe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Recovery Point Objective
Disaster recovery is the process of maintaining or reestablishing vital infrastructure and systems following a natural or human-induced disaster, such as a storm or battle.It employs policies, tools, and procedures. Disaster recovery focuses on the information technology (IT) or technology systems supporting critical business functions as opposed to business continuity. This involves keeping all essential aspects of a business functioning despite significant disruptive events; it can therefore be considered a subset of business continuity. Disaster recovery assumes that the primary site is not immediately recoverable and restores data and services to a secondary site. IT service continuity IT Service Continuity (ITSC) is a subset of business continuity planning (BCP) that focuses on Recovery Point Objective (RPO) and Recovery Time Objective (RTO). It encompasses IT disaster recovery planning and wider IT resilience planning. It also incorporates IT infrastructure and services re ...

Dell EMC (EMC Corporation until 2016) is an American multinational corporation headquartered in Hopkinton, Massachusetts and Round Rock, Texas, United States. Dell EMC sells data storage, information security, virtualization, analytics, cloud computing and other products and services that enable organizations to store, manage, protect, and analyze data. Dell EMC's target markets include large companies and small- and medium-sized businesses across various vertical markets. The company's stock (as EMC Corporation) was added to the New York Stock Exchange on April 6, 1986, and was also listed on the S&P 500 index. EMC was acquired by Dell in 2016; at that time, Forbes noted EMC's "focus on developing and selling data storage and data management hardware and software and convincing its customers to buy its products independent of their other IT buying decisions" based on "best-of-breed." It was later renamed to Dell EMC. Dell uses the EMC name with some of its products. Prior to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NetApp
NetApp, Inc. is an American hybrid cloud data services and data management company headquartered in San Jose, California. It has ranked in the Fortune 500 from 2012–2021. Founded in 1992 with an IPO in 1995, NetApp offers cloud data services for management of applications and data both online and physically. History NetApp was founded in 1992 by David Hitz, James Lau, and Michael Malcolm as Network Appliance, Inc. At the time, its major competitor was Auspex Systems. In 1994, NetApp received venture capital funding from Sequoia Capital. It had its initial public offering in 1995. NetApp thrived in the internet bubble years of the mid 1990s to 2001, during which the company grew to $1 billion in annual revenue. After the bubble burst, NetApp's revenues quickly declined to $800 million in its fiscal year 2002. Since then, the company's revenue has steadily climbed. In 2006, NetApp sold the NetCache product line to Blue Coat Systems. In 2008, Network Appliance offic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operating System
An operating system (OS) is system software that manages computer hardware, software resources, and provides common services for computer programs. Time-sharing operating systems schedule tasks for efficient use of the system and may also include accounting software for cost allocation of processor time, mass storage, printing, and other resources. For hardware functions such as input and output and memory allocation, the operating system acts as an intermediary between programs and the computer hardware, although the application code is usually executed directly by the hardware and frequently makes system calls to an OS function or is interrupted by it. Operating systems are found on many devices that contain a computer from cellular phones and video game consoles to web servers and supercomputers. The dominant general-purpose personal computer operating system is Microsoft Windows with a market share of around 74.99%. macOS by Apple Inc. is in second place (14.84%), and ...

Test Data
Test data is data which has been specifically identified for use in tests, typically of a computer program. Background Some data may be used in a confirmatory way, typically to verify that a given set of input to a given function produces some expected result. Other data may be used in order to challenge the ability of the program to respond to unusual, extreme, exceptional, or unexpected input. Test data may be produced in a focused or systematic way (as is typically the case in domain testing), or by using other, less-focused approaches (as is typically the case in high-volume randomized automated tests). Test data may be produced by the tester, or by a program or function that aids the tester. Test data may be recorded for re-use or used only once. Test data can be created manually, by using data generation tools, or be retrieved from an existing production environment. The data set can consist of synthetic (fake) data, but preferably it consists of representative (real) data. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gmail
Gmail is a free email service provided by Google. As of 2019, it had 1.5 billion active users worldwide. A user typically accesses Gmail in a web browser or the official mobile app. Google also supports the use of email clients via the POP and IMAP protocols. At its launch in 2004, Gmail provided a storage capacity of one gigabyte per user, which was significantly higher than its competitors offered at the time. Today, the service comes with 15 gigabytes of storage. Users can receive emails up to 50 megabytes in size, including attachments, while they can send emails up to 25 megabytes. In order to send larger files, users can insert files from Google Drive into the message. Gmail has a search-oriented interface and a "conversation view" similar to an Internet forum. The service is notable among website developers for its early adoption of Ajax. Google's mail servers automatically scan emails for multiple purposes, including to filter spam and malware, and to add context-s ...

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 ...
