What Is This Tool?
This tool converts data transfer rates from STS3c (payload), a high-bandwidth SONET transport payload, to IDE (DMA mode 1), a legacy DMA data transfer mode for IDE/ATA storage interfaces. It helps users translate between network optical payload rates and storage transfer modes to assist with performance comparisons and system integration.
How to Use This Tool?
-
Enter the value in STS3c (payload) to convert.
-
Select STS3c (payload) as the source unit and IDE (DMA mode 1) as the target unit.
-
Click the convert button to get the equivalent IDE (DMA mode 1) value.
-
Review the output and use it for system performance or integration assessments.
