USB 3.0 Finally Arrives

When you're in front of your PC, waiting for something to transfer to removable media, that's when seconds feel like minutes, and minutes feel like hours. And data storage scenarios such as that one is where the new SuperSpeed USB 3.0's greatest impact will be felt first. As of CES, 17 SuperSpeed USB 3.0-certified products were introduced, including host controllers, adapter cards, motherboards, and hard drives (but no other consumer electronics devices). Still more uncertified USB 3.0 products are on the way, and they can't get here fast enough.

Wall-Plate Design and Installation Issues

Written by Julianus Yu

When you plan your cabling-system installation, you must be aware of a few wall-plate installation issues to make the most efficient installation. The majority of these installation issues come from compliance with the ANSI/TIA/EIA-570-A (for residential) and ANSI/TIA/EIA-568-B (for commercial installations) telecommunications Standards. You’ll have to make certain choices about how best to conform to these Standards based on the type of installation you are doing. These choices will dictate the different steps you’ll need to take during the installation of the different kinds of wall plates.

Manufacturer System

There is no “universal” wall plate. Hundreds of different wall plates are available, each with its design merits and drawbacks. The most important thing to remember about using a particular manufacturer’s wall-plate system in your structured-cabling system is that it is a system. Each component in a wall-plate system is designed to work with the other components and, generally speaking, can’t be used with components from other systems. When designing your cabling system, you must choose the manufacturer and wall-plate system that best suits your needs.

Data Center Essential Element

Written by Julianus Yu

Ramp

Constructing a ramp is the most common and practical way to get equipment in or out of a data center. The ramp must support the weight of the equipment, people, and mechanical devices used to lift the equipment (such as electrical powered pallet jacks).

Aisles

Aisles refer to the space between two rows of racks. Aisles and open space around corners and walls must be wide enough for moving racks and large, heavy equipment (movement that involves a forklift and few people). There must be enough space to remove and roll out a broken rack and roll in a new rack.

Guidelines for Planning a Data Center

Written by Julianus Yu

Following is a list of the key guidelines for design, construction, and deployment of a data center:

Plan in advance —The sooner you start planning, the quicker you will discover potential problems and have time to think of and implement solutions.

Plan for the worst—At least you will have thought of solutions to any impending problems.

Plan for growth —The data center most probably will be in use longer than originally planned. Relocation is cumbersome and companies do not relocate unless absolutely necessary.

Characteristics of an Outstanding Design

Written by Julianus Yu

A data center design that has these four characteristics will be less expensive and far easier to use, maintain, and expand.

Design must be simple —Simplicity makes it difficult to err. To make the work simpler for those using the facility, all cables, circuit breakers, servers, storage devices, network ports, and power outlets must be labeled. When tiles, ports, and outlets are all labeled, it is easy to install new equipment. It is also simple to service or replace existing hardware.

Separating Voice and Data Patch Panels

Written by Julianus Yu

Some installations of voice and data cabling will terminate the cabling on the same patch panel. Although this is not entirely frowned upon by cabling professionals, many will tell you that it is more desirable to have a separate patch panel dedicated to voice applications. This is essential if you use a different category of cable for voice than for data (such as if you use Category 6 cable for data but Category 5e cable for voice). This makes the cabling installation much easier to document and to understand.

Best Practices for Copper Installation

Written by Julianus Yu

We used our own installations of copper cabling, as well as the tips and techniques of many others, to create guidelines for you to follow to ensure that your UTP cabling system will support all the applications you intend it to. These guidelines include the following:

Following standards

One of the most important elements to planning and deploying a new telecommunications infrastructure is to make sure you are following a Standard. In the United States, this Standard is the ANSI/TIA/EIA-568-B Commercial Building Telecommunications Cabling Standard. Standards development usually lags behind what is available on the market, as manufacturers try to advance their technology to gain market share. Getting the latest innovations incorporated into a standard is difficult because these technologies are often not tested and deployed widely enough for the standards committees to feel comfortable approving them.

Why Picking the Right Patch Cables?

Written by Julianus Yu

Patch cables (or patch cords) are the cables that are used to connect 110-type connecting blocks, patch-panel ports, or telecommunication outlets (wallplate outlets) to network equipment or telephones. You should purchase factory-made patch cables. Patch cables are a critical part of the link between a network device (such as a PC) and the network equipment (such as a hub).

Determining appropriate transmission requirements and testing methodology for patch cords was one of the holdups in completing the ANSI/TIA/EIA-B.2-1 Category 6 specification. Low-quality, poorly made, and damaged patch cables very frequently contribute to network problems. Often the patch cable is considered the weakest link in the structured cabling system. Poorly made patch cables will contribute to attenuation loss and increased crosstalk.

Consideration For Relocate Data Center

Written by Julianus Yu

When deciding to relocate a data center we should aware on a geographic location. After selecting a site, the next question is whether to build a data center in an existing building or buy suitable land and construct a building and data center. If you must buy a building, ensure that it has adequate space for equipment, HVAC, and generators, preferably on the first or second floor. However, the build-to-suit option has more flexibility, Here are some factors to consider;

Safe from Natural Hazards
Ideally a data center must be located in an area with no possibility of floods, fire, tornadoes, strong winds, or earthquakes. Since it is impossible to find such an area, you must identify the hazards that are most likely to occur within the data-center lifetime (10, 20, or even 30 years) and make provisions to mitigate their impact.
