for NIC 1 also sets PXE. Because the network cable is not connected to Nic 1, this setting will cause an error to find the installation source. So, enter system settings, set PXE on Nic 4, Nic 1 does not set boot, Nic 4 boot is set to PXE. Then, after rebooting, you find the PXE installation source for the LAN. Note: PXE mode installation is in BIOS mode, not UEFI mode. Resources:How to Install a Operating System on the Dell PowerEdge ServersHttp://w

the above example, my server is PowerEdge 2850, and the CPU is dual-core and dual-threaded, then 0.09/2 = 0.045 (load value/actual number of CPUs ), the CPU load of this system can be ignored. In fact, the CPU of mainstream servers is very powerful. if it is not a special scenario such as application virtualization, the load is basically very small. According to the previous formula, the CPU load threshold of the Nagios alarm is set to the number of
