Lenovo 42U 1200mm Deep RacksProduct Guide
Lenovo 42U 1200 mm Deep Rack offerings are industry-standard 19-inch server cabinets that are designed for high availability server environments. They are optimized to help maximize floor space, expedite installation, simplify cable management, and increase accessibility for improved serviceability. With a depth of 1200 mm (approximately 47 inches), these racks offer expansive rear channels with tool-less button mounts for virtually effortless installation of up to six 0U vertical rack strip power distribution units (PDU) or can easily accommodate vertical cable organizers or mounting other equipment.
Server Rack Height
Illustration of rack unit spacing
Server rack height is one of the more popular ways to classify a server. People often label their rack by its specific height, such as “42U server racks” or, much more informal, “7-foot racks.”
the “U” in “42U” is stands for “rack units,” or “U-spaces,” which equal 1.75 inches. If you are investing in data center racks, the standard height is 48U (“7-foot rack”) or, on some occasions, 42U. The reason this has become “standard” is because it is large enough to allow room for growth and small enough to access equipment easily. For rack enclosures, you might also encounter 22U and 27U racks. In the data center industry, you would consider this a standard “half-rack.”
Plenty of people in the rack infrastructure business build non-standard sizes. This is especially true for open-frame racks. Because of their lighter weight and versatility, open-frame racks can reach heights of up to 70U. At the same time, they can be as small as 5U. Server rack cabinet enclosures, on the other hand, can be a non-standard 18U or 37U.
Изобретение особой единицы измерения «юнит» – это вторая волна глобальной (буквально всемирной) стандартизации. Первая была связана с повсеместным внедрением метрической резьбы, что позволило поставить на конвейер сборку машин и изготовление взаимозаменяемых деталей для них.
Сейчас никого не удивляет, что гайку от карьерного грузовика можно использовать на легковом автомобиле, хотя еще в начале прошлого века каждая деталь могла быть уникальной..
То же самое произошло в конце века XX, когда IT-технологии перестали быть уделом узкого круга профессионалов и стали достоянием миллионов. Оказалось, что единственно возможным способом расположить на единице площади максимально большое количество блоков аппаратуры является их размещение «в стопочку» и формирование аппаратных стоек.
Кто изобрел единицу измерения высоты аппаратного блока, и почему он избрал именно такой размер – достоверно неизвестно. Но благодаря этому человеку компьютерный блок, произведенный на Тайване, без проблем встает в аппаратную стойку в Москве, Нью-Йорке или на исследовательской станции в Антарктиде.

Step 6: Choose a Material and Finish to Suit Your Room
Finally, we’re at the fun step! The last part of your journey to finding the perfect entertainment unit is deciding what material, finish and overall aesthetic will suit your space the best. There are heaps of different TV cabinet and unit options available in a range of unique styles.
When it comes to seamlessly integrating your new piece of furniture into your existing room, one thing you might want to consider is the material it’s made out of. If your room currently includes lots of wood in a particular tone, it might be worthwhile to select something that matches. In a sleeker, more industrial apartment, you could opt for something made of metal or a wood in white or black. Coordination is the key to a curated, cohesive home.
The material and finish of your entertainment unit will also determine its wear and tear over time. Stone, marble and quality wood will last longer, but set you back a little more, whereas vinyl and lesser quality woods may be cheaper but less durable. Metal is usually an affordable option with great lasting power, but doesn’t suit all spaces. It’s up to you to decide what is most important in your new TV unit and go from there!
Here are a few of our favourite entertainment unit styles:
- Scandinavian – simple yet chic, Scandi style blends minimalism, clean lines and light colours. Achieve this effortless look by opting for an entertainment unit that’s no frills yet doesn’t compromise on functionality or flair. We think the Mia Large Entertainment Unit would suit a Scandi home perfectly.
- Coastal – rattan is somehow both timeless and trendy, having made a huge resurgence in recent years. Bring the relaxed, beachy vibes to your home with a coastal-inspired TV unit in a gorgeous rattan material, such as the Caledonia Rattan Entertainment Unit .
- Hamptons – we all know the enviable luxury of Hamptons-style interiors. Light, clean and bright, Hamptons furnishings will make you feel as if you’re living in a beach house year-round. For that airy Hamptons look, opt for light or white wood, a sturdier frame and pretty embellishments. Our go-to is the Monterey Hamptons Style Compact Entertainment Unit .
- Mid-century Modern – take things back to an era long past by adding some mid-century modern furnishings to your digs. Known for dark woods, organic shapes, bright colours and clean lines, mid-century homes are kryptonite to vintage lovers. The Frank Entertainment Unit will make your living room look straight outta the 60s, despite the ultra-modern TV sitting atop it .
- Contemporary – lean into modernity with a contemporary inspired living room, featuring a monochrome colour scheme, materials such as metal, chrome and marble, and simple shapes. Something like the ultra-sleek Slim Large Entertainment Unit in black will bring dimension and visual interest to a contemporary-style room.
- Traditional – finally, if you’re all about ‘if it’s broke, don’t fix it,’ then perhaps traditional furnishings are your style. Always en vogue, classic traditional style is characterised by simplicity, classic shapes and neutral colours. The Enzo Entertainment Unit is the perfect fit for a traditional home.
