Briefly analyze the importance of hardware collocation

Data centers are very important for the company, and sometimes the data center consumes very quickly, in fact, can avoid such a situation, such as a reasonable mix of hardware. Companies don't need to build new data centers because of energy savings. Here are some comments from BurtonGroup analyst Andrew Kutz that companies can take power savings in their existing data centers:

1. Reduce the number of physical servers by selective high-density, for example Virtualization can be applied on the blade server.

2. Can use SANs or other NAS devices to reduce hardware storage to get more storage space. Merging physical units through the data center greatly reduces power consumption, which also means lower costs.

3. Finding high-efficiency hardware like multi-core processors, reducing external redundant electronics, thus saving energy.

4. According to the hierarchical performance technology of the CPU, the energy required by the processor on the associated processor carrier is greatly adjusted.

5. When the temperature of the data center is low, you can dynamically control the fan inside the server to reduce the energy required.

6. The liquid cooler on the server rack can offset the heat from the data center and reduce the energy demand.

7. Arrange the equipment in the data center according to the design of the hot aisle/cold aisle. Although it was a technology in the mid-1990s, "but this is still a very effective approach. "Kutz said.

This design allows the cool air to flow through the vents leading to the front of the server, allowing the hot air to flow from the back end of the server to the AC and back to the duct, thus requiring cooling. Energy is greatly reduced.

8. Find multi-threaded software that supports multi-core processors. "Today you can buy a new out-of-the-box multi-core server, but if the software doesn't support it, you still can't make good use of it. "Kutz said. "This is the scope of the software engineer's work, they need to ensure that their software supports multi-threading and can be used on multi-core processors. "

The importance of hardware collocation is reflected here, so many times you can not only focus on the data itself, the impact of hardware is also very big, I hope to help everyone.
