5 things to note, when choosing to buy rack

________________________________________
Server Rack (also known as host tables) and the accompanying accessories are essentials to bring success to your company, because they give you company where the storage devices serve major activity of the company. Therefore, the choice of host tables and matching accessories make reasonable power supply, cooling and maximum protection for the device, all operations are continuous operation and stable by minimizing downtime and helping to manage, and organize data centers more efficient. Here, 3C Electric please provide additional 5 things you need to keep in mind when selecting a server buy tables:

1. Selected from the appropriate size:

Please select the appropriate cupboard space to store all of your existing equipment and make sure that you choose has enough closet space for expansion plans in the future, as well as the purchase of additional equipment beyond the expected. Cases devices is measured by the standards of the Association of Electronics Industry sectors (Electronic Industries Alliance - EIA), known as "cabinet unit" (Rack Units) or "U". 1 Unit cabinet by 1.75 "height.
Please note the space for parts, such as the adjustment of environmental equipment cabinets, equipment control power management, LCD screens and battery reserves when needed. For example, if you need space located 20 2U server type, you can choose the cabinet height is 44U to put all the parts are attached as socket 1U, 2U or an electric charge. Inside height of cabinet is measured from the highest point to the bottom point of the bottom of the cabinet; inside the cabinet depth is measured from the inside of the 2 doors, front and rear; cabinet width will be measured from the panel to the other side.
Make sure that the outside dimensions of the cabinet can be placed in the pantry space, check to see if it can be passed through all the doors or not, and make sure that you will spend a gap suitable for replacing cabinets meet the safety rules. Please note that these techniques always use proper installation of cabinets including the use of heavy equipment bottom of the cabinet to avoid the heavy shelving above, determine before the device you want placed in the front and back of the cabinet (based on the number of times you add or remove devices in the cabinet), plus you also need to add an installation to support your heavy equipment and / or high above .

2. Safety measures for cabinets:

The appropriate safety are essential for all activities as well as the operation of your device. So understand your server tables suitable for the entire security strategy is how very important. There are several methods to help you improve the security of the server tables and other equipment in your data center.
Let's start from the note to the purchase of tables the server has locks on both the front and rear doors, Electric current 3C has a lot of blood from the selection provided. Next, using environmental control equipment to control environmental initiative in your closet. Also, allows administrators to control continuous amperage on each circuit, drainage, temperature and other changes, then send automated messages via SMTP / SMS, SNMP when the conditions exceeds the predefined threshold, a number of environmental control devices with sensing element on closing or opening the door to help common conditions and can alert administrators when a wing open the door.
(When a cabinet change in relation to the appearance of the threshold has been determined, this device will report "error"). In addition, there are also devices available to work with cameras and sensing element enables administrators to continuously control the cabinet and the cabinet room servers, as well as the sound recording bar. If you are planning a new data center, you also need to pay attention to the physical security methods, such as: building remote data center with main roads, limited window in data center, installing security doors.

3. Choose from is designed to fit your requirements:

Most manufacturers will give customers a lot of options so they can choose the server tables to meet the specific requirements in cabinet installation environment. Here are some parts of the cabinets you need to keep in mind when choosing:

Shelf:

The supplier selection since some servers including racks fixed or adjustable frame with 4 points, the cabinets have sliding panel frame 2 points clear of the pores and resistant to heavy or the kneeling leg shelf, shelf and middleman. Choose shelf depth is 6 inches less than the total depth of the cabinet - for example, if you select cabinets 30 inches deep, the shelves have a depth of 24 inches.

The panel placed above or beside:

The top of the cabinet panels protect equipment from the outside material. Options include perforated for ventilation slots, the slots conduit for cable management and installation of additional ventilators. The side panels for protection and are often available as an option: fixed table, moving table, table with vents (louvered).

The sliding tray:

Most cabinets are supplied with 2 sets of sliding tray. However, the sliding tray add may be necessary to accommodate the different depth and help the cabinet assembly and transport easier. Most manufacturers allow you to choose from the versatile sliding tray (square holes fitted with cage nuts). The multipurpose tray will slide 19 inches wide support installation of network equipment and servers all equipment. EIA standard sliding tray ensures 19 inches width for installation of network equipment and some equipment in the server room cabinet manufacturers. The sliding tray is usually the standard square hole ANSI/EIA-310-D (1992). Most accessories manufacturers are aware that the slide tray will have square holes for mounting nuts, whole blood from the current slide trays are used with square holes.

The cabinet:

The choices available include foot cabinet cabinet foot type can fight down to stabilize the cabinet in case the cabinet is assembled so heavy, the wheel is attached to the bottom of the tables to support host migration cabinets; most types of server cabinets should be mounted wheel to ensure that the cabinet can be moved easily.

4. Notice to the latest power engineering:

Distribution cabinets are used to distribute power to the server through electric wires. The power transmission line is specifically designed for server cabinets and mounting points on the roof or behind the cabinets. The power lines are generally divided into two categories: standard and high technologies.
While standard power strips can provide valuable information, such as the replacement fuse indicator, showing the operating parameters, and this information needs to be personalized and managed on the website . In contrast, the high-tech power strip controller remote power supply, allowing the administrator to resolve the problem restart the server and the device, as well as the problems that occur from any location setpoint server with an internet connection, in addition to high-tech power strip reduces server downtime and recover operations quickly.
The electrical control products not only provide intelligent power control system, which also allows the administrator to make the most progress in the electrical distribution, such as 3-phase power source.
3-phase power source except the product power management control, but many possible solutions and activities associated with it. Compared with single-phase power supply, power supply 3-phase circuit using less than, provides more balanced power load, helping to reduce the total power required for the distribution of electrical appliances, and significant increase in amperage tables available on the server.
For example, in a traditional environment cabinet, 4 power supply circuit 20A will be available 64A (assuming that the maximum load capacity is 80%). In contrast, 3-phase power supply can deliver up to 51.6A per circuit, 82A or more with power available, as we only need to use 2 circuits (with a maximum load capacity is 80%).
Also use 3 phase power also saves costs, especially when the experts have estimated that, in future electricity costs could rise as much as 10 times the current or power for the information technology will be less than about 20 to 30%. Factors related to the power supply should be noted, including the number of sockets you need and the requirements for standby power requirements as well as charged.

5. Clearly define strategies for cabinet cooling servers:

Be clear about the role of strategic data center cooling your complete tables for the server. Type of cabinets you choose will depend on the cooling method is used in your environment cabinet. The heat released from a host tables are different, depending on the type of equipment and layout density, the heat can be around 4kW to 12kW or more for a cabinet, a few experts have estimated that the increase in density and environmental thicker design of the devices in the future will make the heat emitted from a server tables will increase from 30kW to 50kW.

The cabinets have ventilation holes on the cabinet body:

Selection of the cabinet has vents on the cabinet body for maximum ventilation cooling method is first to your data center or installation of the cooling fan and ventilated room surrounded servers (fan, ventilation, air conditioning and / or air conditioning units computer room (Computer room air conditioning - CRAC) and the top floor).

The completely sealed cabinet:

If your cabinet room is equipped with air conditioning and chiller cabinets select servers completely sealed.
When the application requires more energy and increase server density, the liquid-cooled machine (Liquid Cooling Units) (including modules, cooling solutions intermediate temperature high density use of heat exchangers such as air or water for cooling efficiency) will be used. One of the main benefits of the machine using liquid cooling is effective and brings them back just does not affect the existence of the HVAC system. The liquid-cooled machines are mounted in brackets, in one word "side" (side car) with 3 modules per cabinet cooling, and can provide a total cooling capacity of about 30kW.
The air-conditioning equipment is usually not used in the data center environment that more traditional full CRAC systems. However, if IT equipment is placed outside of a data center environmental control, such as a warehouse or factory, sometimes the air conditioner cabinet that will be used. It is important to note that the only cabinet air conditioners are designed for use in industrial space and the large space, because they emit noise and water vapor, they also suck hot air devices placed in this room. In a large room, the heat will be dispersed. In contrast, in a smaller room or limited space as storage room, the hot air will be sucked in from AC parts, this is the reason why the room becomes very hot. If an AC unit is used in a small room, we need to implement the methods suck hot air out of the room. The modular air cooling capacity will be different, so to get as much power suit your needs.
