One or more meals a day to adhere to the right amount of the principle
We should arrange the time and quantity of meals and eat regularly. In general, breakfast is arranged in 6:30~8:30, lunch is arranged in 11:30~13:30, dinner is in 18:00~20:00; the energy provided by breakfast should account for the total energy of the whole day 25%~30%, the lunch should occupy the 30%~40% and the dinner should be 30%~40%.
Food distribution for meals a day
Breakfast should be arranged in half an hour after

down the database may reach 100G to 200G. The main effects due to database enlargement are as follows: 1, resulting in higher disk storage costs; a 200G database plus backup requires at least 1 T disks to be barely enough. 2, the database performance degradation. 3, the potential risk of database failure increased. (although there is no direct evidence, but simple reasoning can draw that conclusion) 4, the time to back up the database is too long. Co

Temporary tables are automatically cleaned or displayed by the drop temporary table at the end of the session.Considerations for deleting large tablesFor table deletions, because the INNODB engine maintains a global exclusive lock at the table cache level until the drop table is complete, other operations on the table are stuck. For larger tables, the drop table operation can take a long time, so an effec

The "armored optical jumper" is a new type of optical jumper, which may be unfamiliar to you. Armored optical fiber Jumpers are highly adaptive and cost-effective.
Armored optical fiber jumpers can be directly laid in data centers and various harsh environments, without the need to use protective casings, saving space and reducing construction costs, greatly improving the convenience of network maintenance.
The optical fiber jumper is customized based on the actual distance between the main sw
Gigabit RJ-45 ports and 12 miniGBIC (SFP) slots to provide Gigabit fiber connections (each 1000Base-T is shared with the corresponding MiniGBIC port ).
Users can configure flexible product configurations according to their specific requirements. All 10/100/M copper ports support port self-adaptation, self-negotiation, and MDI/MDIX self-adaptation. SFP module supports hot dial. Similar to GSM7324, all ports

In the future, with the improvement of optical module technology and smaller optical modules, the 0.48 million g port density that a single slot can provide will be higher. Now, rack-mounted switches with single slot providing M ports will become popular. Due to the limited cabinet size of the data center, the width of the rack-mounted switch cannot be expanded. Therefore, the 0.48 million MB port can be provided t
