Reference excerpt

Quantum Corporation is a data storage, management, and protection company that provides technology to store, manage, archive, and protect video and unstructured data throughout the data life cycle. Their products are used by enterprises, media and entertainment companies, government agencies, data companies, and life science organizations. Quantum is headquartered in San Jose, California and has offices around the world. The company was dual-listed on the NASDAQ Global Market under the ticker symbol "QMCO", and on the Börse Frankfurt under the ticker symbol "QNT2".

History Quantum was founded in 1980 as Quantum Corp. By 1984, it led the market for mid-capacity 5.25-inch drives. That year, a subsidiary was launched called Plus Development to focus on the development of hardcards. Plus Development became a successful designer of 3.5-inch drives with Matsushita Kotobuki Electronics (now Panasonic) as the contract manufacturer. By 1989, Quantum led the compact drive market. The company had 11 new models of 3.5-inch and 2.5-inch drives, and had signed distribution agreements with Rein Elektronik in Germany and Inelco Peripheriques in France. It also merged its subsidiary Plus Development Corporation into its Commercial Products Division. Quantum was the largest drive producer worldwide in 1994. In 2000, Maxtor agreed to acquire Quantum's hard disk drive group. In 2004, Quantum became a member of the LTO Consortium after acquiring Certance. In 2012, Quantum announced Q-Cloud, which combines on-premise storage with cloud storage. In 2015, the company released a multi-tier storage product, StorNext 5.3, which supports Q-Cloud and powers the company's Xcellis workflow storage technology. In 2018, Jamie Lerner became CEO, and Quantum shifted focus from hard drives/tape to providing data storage, management, and protection for video and other unstructured data. In 2019, the company added a subscription for cloud-based device management and product, called Distributed Cloud Services. In 2020-2021 Quantum acquired technology to support the shift in focus including ActiveScale and CatDV. They also acquired video surveillance software from Pivot3. During the COVID-19 pandemic, Quantum was a recipient of a government loan of US$10 million as part of the Paycheck Protection Program (PPP). In October 2021, Quantum and IBM announced they would work together to develop LTO-10, the next generation of Linear Tape-Open (LTO) technology. In April 2023, Quantum announced a new scale-out unstructured data storage platform called Myriad. The solution is software-defined, initially running on Quantum-supplied hardware but capable of running on public cloud infrastructure.

Acquisitions 1998 – ATL Products, a manufacturer of automated tape libraries. 1999 – Meridian Data, a network-attached storage supplier. 2001 – M4 Data (Holdings) Ltd., a manufacturer of tape libraries. 2002 – Benchmark Storage Innovations, who manufactured the VStape product line under a Quantum license. 2005 – Certance, the former tape business of Seagate Technology, becoming a member of the LTO consortium. 2006 – Advanced Digital Information Corporation (ADIC), Scalar brand tape libraries, StorNext filesystem and de-duplication technology. 2011 – Pancetera Software, a specialist in data management and protection for virtual environments, for $12 million. 2020 – ActiveScale object storage business acquired from Western Digital. 2020 – UK-based Square Box Systems Ltd, maker of CatDV and a specialist in data cataloging, user collaboration, and digital asset management software. 2021 – Video surveillance assets from Pivot3, a hyperconverged infrastructure company. 2021 – EnCloudEn, a hyperconverged infrastructure (HCI) software company.

Products Quantum provides data storage, management, and protection for video and other unstructured data. The company's products, solutions and services include:

File system software

StorNext

Quantum's StorNext software enables video editing and management of large video and image datasets. StorNext software is a parallel file processing system providing fast streaming performance and data access, a shared file storage environment for MacOS, Microsoft Windows, and Linux workstations, and intelligent data management to protect data across its lifecycle. StorNext's storage arrays include the hybrid Quantum QXS-Series. StorNext is also integrated with tape storage and can assign infrequently used but important data to tape to create a large-scale active archive. In 2011, the company added the StorNext appliance offerings to its product family. In addition to the StorNext Archive Enabled Library (AEL), the company added a metadata controller (StorNext M330), a scale-out gateway appliance (G300), and several scalable storage systems (QM1200, QS1200 and QD6000). In February 2012, the company added the QS2400 Storage System, followed in May by the M660 metadata appliance. The HSeries is a line of high-performance storage arrays. In January 2021, Quantum introduced its H2000 series of hybrid arrays that provide on-premise storage for media production workflows and block storage arrays that provide an alternative to QXS. It includes the 2U H2012 and the H2024, which provides 307 TB after data reduction. The H4000 appliance series was released in late 2021. The series uses a converged infrastructure that runs file, block, and client services virtually on a single box. In April 2022, Quantum released the H4000 Essential. It is for small, independent creative teams and provides shared storage and automatic content indexing, discovery, and workflow collaboration by combining Quantum's CatDV asset management and the company's StorNext 7 shared storage software.

Worked examples

Example 1 — a first encounter with Quantum Corporation

Start with the simplest possible case. Write down what Quantum Corporation claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In computer science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Quantum Corporation before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Quantum Corporation ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Quantum Corporation

In research: Quantum Corporation appears in computer science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Quantum Corporation in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Quantum Corporation is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1980 establishments in California, Companies listed on the Frankfurt Stock Exchange, Companies listed on the Nasdaq, so understanding it makes those chapters shorter.
In everyday life: Look for Quantum Corporation outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
