What is the best way to prevent power failure in the computer room?

Yes, you want to use UPS

It can be expensive though.

If the decoration design of the computer room is equipped with an uninterruptible power supply, the important computer room also needs to be powered by dual power supplies (dual generators in the power plant, or two power plants for power supply).

Some companies' small computer rooms are not equipped with diesel engines for various reasons, and no one is on duty 24 hours a day, many UPS can automatically shut down the server, but the computer room with virtualization is easy to turn off the server.

The ideal shutdown process should be (using VMware vSphere as an example):

One. Shut down the virtual machine.

Start by shutting down less dependent virtual machines, such as web servers;

Shut down virtual machines that rely on a lot of things, such as databases.

Shut down some management servers (ESXi) (such as vCenter and Horizon) to prevent other virtual machines from being woken up by services such as vCenter and Horizon during a hot shutdown.

Shut down other servers.

UPS cooperates with the Decaron data center emergency management host.

After the mains power is cut off, the UPS first holds (usually half an hour) after the emergency management host detects the mains power failure (after the mains power is off, the host relies on the UPS to support power), performs shutdown operations (shutting down virtual machines and server clusters), and simulates the administrator to manually shut down the virtual machine, server, storage and other hot shutdown operations.

The cluster can be automatically woken up after the mains is energized.

Use the UPS to power the server, and set the amount of time on each server when the UPS will power up the power and then automatically shut down.

To put it simply, the effective way to ensure that the power is not interrupted is to connect multiple power systems in parallel, one is interrupted, and the other is started immediately.

In fact, because the server has high requirements for continuous power, no matter which computer room is very cautious when dealing with this problem. For example, the Xixin Center in Chengdu uses 4 independent substations to input mains power from different substations, and is equipped with 24 2000kW diesel generators and 3 3000kW gas turbine generators, with a total output of 10,000 kW. The power availability of the UPS system that lasts for more than 1 hour after the power failure reaches the level; The annual planned maintenance power outage time does not exceed 30 minutes, ensuring that each cabinet is connected from different distribution cabinets to achieve dual power supply.

As is the case this summer, more than 1 3 regions in China are under continuous hot weather, the demand for electricity has increased significantly, and the mains power may be interrupted at any time. Or in the event of a natural disaster such as a flood or **, if the power system of the computer room is all from the mains, there will still be a risk of power interruption. Therefore, a good IDC computer room will be equipped with its own power generation equipment to cope with unexpected needs.

The computer room has a UPS system (uninterruptible power supply system), and the power supply system will also supply power after a power failure, but how can your company's computer room have a short power outage on a holiday? It is not good to lose power in the computer room, and it is generally necessary to maintain the same power.

Question 3 Answer: Yes Environmental and dynamic detection system system. You can display the status of the computer room at the door, and if there is a fire or water leakage, you can set up SMS notifications or email notifications.

The special air conditioner in the computer room has the function of setting the incoming call to start automatically or not, so don't worry about this.

You can buy a SMS alarm module to connect to the dry contact of the air conditioner, as long as there is an alarm, the module will trigger the automatic SMS prompt.

Yes, there are many ways to achieve it, such as the UPS monitoring card we make will provide alarm, mobile phone SMS reminder, and the software company needs to do it.

There are generally two ways to deal with sudden power failure in the data center room.

1. If UPS is configured in the data center computer room, after the mains power is cut off, the UPS will start the battery discharge and provide uninterrupted power to the back-end equipment through the UPS inverter. If the power is cut off for a long time, the generator at the front can be started to power the back-end equipment before the battery is discharged. In this kind of equipment room equipped with UPS, the back-end equipment can provide uninterrupted power supply.

2. If UPS is not configured in the data center computer room, and the mains power is cut off, then the generator configured in the data center can only be started to supply power to the back-end equipment through ATS switching. This kind of computer room without UPS can only be cut off after a power failure, and then the power supply is provided through the generator.

The specialized computer rooms are basically in the enterprise units. Units definitely have their own generators. The network is basically fiber-optic. If you have a more professional server room, there must be a dedicated generator to supply power in case of emergency.

The server must have large UPS. In the event of a power outage, the generator is usually activated within half an hour. UPS is used to fill the time before the generator starts and stabilizes the voltage.

Sudden and prolonged power outages (e.g., burning transformers) will generally turn off the server before the UPS power is exhausted. The UPS of the unit where I work has 8 servers and switches (there are 16 batteries in the UPS, each of which is at least thirty or forty kilograms), and it can only support 40 to 50 minutes.

Uninterrupted network, ensure the power supply of modem and switch, as long as the line on the side of the network provider does not have problems, it will not be broken.

1. For precision air conditioners, frequent power failures affect the life of the compressor, and there may be electrophoresis damage.

2. For UPS, frequent power failure may cause over-discharge of the battery, reduce the life, and the electrophoresis will have an impact on the inverter and rectifier.

3. For network equipment, frequent power failure may cause configuration loss, switch chip damage, etc.

4. For the server, frequent power failure can cause data loss, the server does not start, and the motherboard chip is damaged.
