Abstract:
An apparatus comprising an array controller and a frame buffer. The array controller may be configured to read/write data to/from a drive array in response to one or more input/output requests. The frame buffer may be implemented within the array controller and may be configured to perform (i) a first data integrity check to determine a first type of data error and (ii) a second data integrity check to determine a second type of data error. The frame buffer may log occurrences of the first type of error and the second type of error in a field transmitted with the data. The field may be used to determine a source of possible corruption of the data.
