IntelliFlash

IntelliFlash is a computer science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand IntelliFlash rather than just read about it. In short: IntelliFlash is a brand of DataDirect Networks (DDN) based in San Jose that manufactures flash storage arrays. The company, then known as Tegile Systems, was acquired by Western Digital in 2017 and by DDN in September 2019.

Key takeaways

IntelliFlash belongs to computer science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect IntelliFlash to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of IntelliFlash from memory before moving on to harder problems.

Reference excerpt

IntelliFlash is a brand of DataDirect Networks (DDN) based in San Jose that manufactures flash storage arrays. The company, then known as Tegile Systems, was acquired by Western Digital in 2017 and by DDN in September 2019.

History Tegile Systems was founded in 2010 by Rohit Kshetrapal, Rajesh Nair, Justin Cheen, and Alok Agrawal. In February 2012, Tegile came out of stealth mode when it announced a product line called Zebi. In 2013, a $32 million investment led by Meritech Capital Partners, which included a corporate venture capital investment led by Alex Lam from SanDisk Ventures. In May 2015, a round of $70 million was announced, with additional investors Capricorn Investment Group, Cross Creek Advisors and Pine River Capital Management. By the end of 2015, Tegile had an estimated 360 employees. In 2017 Western Digital bought Tegile Systems and then rebranded it as IntelliFlash. Western Digital sold IntelliFlash to DDN in September 2019.

Technology Tegile developed what the company calls IntelliFlash Metadata Acceleration, which is a way to store metadata on high speed solid state disks, apart from the underlying data. Some competitors are noted as Nimble Storage and Tintri.

Worked examples

Example 1 — a first encounter with IntelliFlash

Start with the simplest possible case. Write down what IntelliFlash 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 IntelliFlash 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 IntelliFlash 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 IntelliFlash

In research: IntelliFlash 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 IntelliFlash 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: IntelliFlash is common in secondary-school and first-year university syllabi. It links to neighbouring topics 2010 establishments in California, 2017 mergers and acquisitions, 2019 mergers and acquisitions, so understanding it makes those chapters shorter.
In everyday life: Look for IntelliFlash 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.

Frequently asked questions

What is IntelliFlash in simple terms?

Why does IntelliFlash matter?

Because it connects several computer science ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study IntelliFlash?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
