Sun Blade

Sun Blade 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 Sun Blade rather than just read about it. In short: Sun Blade is a line of blade server computer systems sold by Sun Microsystems from 2006 onwards. In June 2006, Sun announced the AMD Opteron-based Sun Blade 8000 modular blade server system.

Key takeaways

Sun Blade 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 Sun Blade to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Sun Blade from memory before moving on to harder problems.

Reference excerpt

Sun Blade is a line of blade server computer systems sold by Sun Microsystems from 2006 onwards. In June 2006, Sun announced the AMD Opteron-based Sun Blade 8000 modular blade server system. The Sun Blade 8000 chassis can hold up to 10 Sun Blade X8420 or X8440 modules. In July 2007, Sun launched the Sun Blade 6000 Modular System. This allowed up to 10 mixed UltraSPARC and x64 architecture blades. The Sun Blade T6300 and T6320 modules run Solaris and use UltraSPARC T1 and UltraSPARC T2 processors respectively, while the Sun Blade X6220 and X6250 modules use AMD Opteron or Intel Xeon 5000-series processors respectively. In November 2007, Sun announced the Sun Blade 6048 Modular System, supporting up to 48 UltraSPARC, AMD Opteron and/or Intel Xeon blades. The X-series blades support Solaris, Oracle Linux, RHEL, SLES, Windows Server or VMware.

Worked examples

Example 1 — a first encounter with Sun Blade

Start with the simplest possible case. Write down what Sun Blade 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 Sun Blade 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 Sun Blade 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 Sun Blade

In research: Sun Blade 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 Sun Blade 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: Sun Blade is common in secondary-school and first-year university syllabi. It links to neighbouring topics Blade servers, Computer-related introductions in 2006, Computer hardware stubs, so understanding it makes those chapters shorter.
In everyday life: Look for Sun Blade 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 Sun Blade in simple terms?

Sun Blade is a line of blade server computer systems sold by Sun Microsystems from 2006 onwards. In June 2006, Sun announced the AMD Opteron-based Sun Blade 8000 modular blade server system.

Why does Sun Blade 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 Sun Blade?

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.
