performance state data. You can see the difference is: the normal server load average is approximately 2, the fault server is close to 6. From the memory state, the normal server's physical memory is 64GB, using 50GB or so, swap is not enabled, the failed server physical memory 32GB all use, and enabled more than 500 MB swap.Preliminary judgment, the fault is because a server only 32GB, insufficient memory resources, resulting in the request processi

A layer-3 network is a layered layer-3 network. The three-tier network architecture adopts a hierarchical model design, which divides the complex network design into several layers. Each layer focuses on some specific functions, in this way, a complex big problem can become many simple small problems. The three-tier network architecture has three layers: the core layer (the High-speed switching backbone of the Network), the convergence layer (providin

a straight line. Use the crossover line to cascade the switch through the normal port. Cascade of Switch Fibre ports Because the price of the switch fibre port is still very expensive, the fiber is used primarily for connecting between the core switch and the backbone switch, or for cascading between the backbone switches. It should be noted that the switch fibre ports are not stacked and can only be used for cascading. Cross-connect of fiber jump
