The data center design recognized by TIA-942 is an important standard that many companies will focus on when building data centers. After all, this standard is very detailed about the reliability and security of data centers – although some people may think it is just a bunch of boring text terms, in fact, when you really need to design, you will find its usefulness! Simply put, TIA-942 Rated Data is to plan and build all aspects of the data center according to the TIA-942 standard, from infrastructure to equipment layout, and to some technical parameters, it must meet its requirements as much as possible.
1. Infrastructure planning : There is too much content in this part. First of all, we must consider the power system, such as how to allocate the input power, whether a backup power is needed, how to determine the capacity of the UPS to be sufficient, and there is room for space? There is also a refrigeration system, which is also very critical. There are so many servers in the data center that run very much heat. If not done well, the server will easily have problems. Therefore, the selection of air conditioners, the design of air ducts, and even the isolation of hot and cold channels. TIA-942 Rated Data Center Design must be carefully considered in accordance with the requirements in the standards; provide global procurement services for weak current intelligent products! Also, the layout of the cabinets should not be placed as you want. It should consider whether the equipment is convenient to install and maintain, and whether the heat dissipation effect will be affected. These are all the key considerations in infrastructure planning.
2. Reliability level classification : The TIA-942 standard divides the reliability of data centers into several levels, from Tier1 to Tier4. The higher the level, the better the reliability, but the construction cost and complexity are often higher. The Tier 1 level may be the most basic configuration, with only one power supply and a simple refrigeration system. Once a minor failure occurs, it may affect normal operation; while the Tier 4 level is different. It requires a completely independent dual-channel power supply and refrigeration system. If any part has problems, the other part can be taken over immediately, so there will be almost no downtime. Of course, the construction of this level will also be much larger.
3. Key points of physical security design : Although physical security is not often mentioned like network security, its status in TIA-942 Rated Data is not at all low. For example, when choosing a data center, it is best not to choose places where natural disasters occur frequently, such as earthquake zones or flood areas, you must avoid them; then the building itself, whether the wall materials are fire-proof, and whether the doors need to be equipped with password locks or biometric devices. These are all very important. There is also the division of internal areas, which are the core computer room areas, and whether tourists and staff can enter and exit at will, must have clear regulations. For example, installing surveillance cameras and setting up access control systems, these are all considerations that must be included in physical security design.
4. Details of network cabling specifications : Cabling looks simple, but if it is not done well in the data center, it will cause a headache to detect problems later, and it will also affect the efficiency and stability of data transmission. The requirements for wiring in the TIA-942 standard are quite specific, such as how to choose the type, whether to use copper cables or optical cables, and the transmission distance of different types of cables are specified; there are also how to organize the cables in the cabinet so that they will not be messy, and how to mark them to see which wire is connected to which device. Although these details are small, they are too important for the daily operation and maintenance of the data center!
Q: Under the TIA-942 standard, do the grounding system of the data center have any special requirements?
A: Grounding system, this does have special regulations in TIA-942. It requires that the data center must have an independent grounding pole, and the grounding resistance should not be too large. Generally speaking, it must be lower than a certain value. The specific amount is written in the original text. I can't remember it clearly for a while… However, the main purpose is to ensure the safe operation of the equipment, prevent the accumulation of static electricity to damage the equipment, and at the same time avoid affecting the transmission quality of the data signal due to poor grounding. Therefore, the design and construction of the grounding system must be strictly carried out in accordance with the standards and cannot be careless!
Q: Is TIA-942 Rated Data only suitable for large data centers?
A: Actually, this is not the case! Although large data centers have higher requirements for reliability and scalability and are easier to follow the TIA-942 standard, those small and medium-sized data centers can also be designed based on their actual needs and budgets. For example, the basic power, refrigeration, and wiring principles are reference points for any data center of scale. It does not mean that only large houses can use this standard, and small houses cannot be used. The key is to make choices based on the actual situation and needs of the company.
I personally think that TIA-942 Rated Data does provide a very good guidance framework for the construction of data centers. Whether it is to build a new data center or upgrade and transform existing data centers, it is definitely correct to refer to this standard. Of course, when implementing the specific implementation, we must also consider the company's own business characteristics, budget conditions and other factors. After all, the best thing is suitable for you!
