Tips & Best Practices
-
Verify that legacy hardware and cables support the IDE (UDMA-33) mode to get accurate benchmarks
-
Consider the limitations of IDE (UDMA-33) throughput relative to modern standards when planning upgrades
-
Use the converter to understand how legacy data rates correspond to fixed SONET transmission lines
-
Keep in mind framing and overhead differences when comparing throughput and bandwidth capacities
-
Apply converted results to assist in network design and equipment interoperability assessments
Limitations
-
IDE (UDMA-33) is a legacy standard with limited maximum data transfer speed, not suitable for high-speed modern networks
-
STS3 signals have fixed SONET line rates; exact bandwidth alignment may differ due to framing and overhead
-
Conversion does not reflect real-time network performance but theoretical transfer rate equivalences
Frequently Asked Questions
