The high cost and complexity of data centers has become a well-known fact, data center virtualization has also become a hot topic, but the data center is faced with how serious the problem, virtualization in the

After that, we will assess the hardware environment and soft environment of the data center, for more details about the basic facilities of the data center, including the po

5. Continuously Cultivate Talents
Ensure that everyone has independent access to the data center, including IT, emergency, security, and facility maintenance personnel, so that they can learn the basic equipment-related knowledge to avoid power off by mistake.
6. Secure Access Policy
There is a high risk of organizational security without a
, foreground tasks usually take precedence over background tasks, while background tasks want to be fairly scheduled. This is also why preemptive scheduling is better than cooperative scheduling.
There are also two types of applications in the data center: online and offline. Online systems are directly oriented to users, while offline systems are mostly used for data

40 GB and GB Ethernet. If each server can be connected with 10 Gb of data, and applications need to access and manage data, this means that the virtual machine density of each server node is greater, the bandwidth demand will increase exponentially. According to the definition, assume that a server has 10 Gb of bandwidth, then the upstream traffic needs 40 or 100 Gb. 100Gb is not a required configuration.

To ensure that the electronic computer room meets the requirements of various technical environments, all public professional technical rooms are required. These include: transformer room, high and low voltage power distribution room, uninterruptible power supply room, battery room, generator room, air conditioner Room, fire extinguishing equipment r

These stupid things should be avoided in data center management
In many cases, each of us does not think we will make stupid mistakes. However, when an error occurs, we often regret it.
In terms of data center management, we also need to eliminate stupid errors. You must always be extremely cautious when creating a ne
Institute to consult 200 data center managers from the United States and the UK. The biggest dilemma, according to the survey, is that 43% of data center managers still rely on manual methods to replace DCIM tools for capacity planning and forecasting.As we enter the digital age, Microsoft's Excel forms software, and
AC power consumption is larger, while the DC power supply is the opposite. The DC power supply is smaller, and the DC power supply can be transmitted only with two wires. However, the DC voltage phase remains unchanged and is vulnerable to external interference when transmitting small signals. However, compared with AC power supply, DC power supply can save about 15% ~ 30% of the energy consumption, which cannot be rejected by large data centers. The

In these data centers, the built-in routers and switches are responsible for global information exchange, and their information processing speed is about 0.2 million times that of home Internet connections.

The lifting, lifting, and shockproof platforms generally have the following features:

• 2600mm Clearance height exists between anti-shock platforms and fake ceilings
