2.1.1.9 ECC Memory Service
Figure 33. ECC Memory Service
ECC memory has the capability to correct single-bit errors. A problem might
come up that the memory has an increasing amount of memory errors. As long
as these errors are just single-bit errors, it is not a real problem because the
ECC memory controller takes care of it. But the administrator should be informed
about this so that he or she can take appropriate action to have the system
serviced before a double-bit error occurs, which will result in a system hang-up.
With the ECC Memory Service you can set thresholds to monitor the single-bit
errors and create an alert if this value is exceeded. This can be used to take
preventive action.
