Power On And Power Off Problems - Lenovo ThinkEdge SE360 V2 User Manual

Network performance
Complete the following steps until the problem is solved:
1. Isolate which network is operating slowly (such as storage, data, and management). You might find it
helpful to use ping tools or operating-system tools such as task manager or resource manager.
2. Check for traffic congestion on the network.
3. Update the NIC device driver, or the storage device controller device driver.
4. Use the traffic-diagnostic tools that are provided by the IO-module manufacturer.
Operating system performance
Complete the following steps until the problem is solved:
1. If you have recently made changes to the compute node (for example updated device drivers or installed
software applications) remove the changes.
2. Check for any networking issues.
3. Check the operating system logs for performance related errors.
4. Check for events related to high temperatures and power issues as the compute node might be throttled
to help with cooling. If it is throttled, reduce the workload on the compute node to help improve
performance.
5. Check for events related to disabled DIMMs. If you do not have enough memory for the application
workload, your operating system will have poor performance.
6. Ensure that the workload is not too high for the configuration.
