Double data rate channel sensitivity and dual in-line memory module population optimization

A method comprising:

• performing, by a processor, a first input/output (I/O) health check of a first I/O device;
• gathering a first I/O health check data from the first I/O health check performed;
• calculating a first set of deltas between a first set of channel margins associated with the first I/O device based on the first I/O health check data and expected channel margins;
• determining whether the first set of deltas are within the expected channel margins for the first I/O device;
• when the first set of deltas is within the expected channel margins, then identifying the first I/O device as healthy;
• when the first set of deltas is not within the expected channel margins, then identifying the first I/O device as unhealthy;
• and
• calculating a second set of deltas between a second set of channel margins associated with a second I/O device based on the first I/O health check data and the expected channel margins.

A non-transitory computer-readable medium to store instructions that are executable to perform operations comprising:

• performing a first input/output (I/O) health check of a first I/O device and a second I/O device;
• gathering a first I/O health check data from the first I/O health check performed;
• calculating deltas between a first set of channel margins associated with the first I/O device based on the first I/O health check data and expected channel margins;
• calculating deltas between a second set of channel margins associated with the second I/O device based on the first I/O health check data and the expected channel margins of the first I/O device;
• when the deltas between the first set of channel margins is within the expected channel margins, then identifying the first I/O device as healthy;
• and
• when the deltas between the first set of channel margins is not within the expected channel margins, then identifying the first I/O device as unhealthy.
