What Is This Tool?
This tool converts data transfer measurements from Virtual Tributary 6 (VT6) payload units, used in SONET/SDH telecommunications networks, to IDE (PIO mode 3) units, which represent a programmed I/O transfer mode for legacy Parallel ATA/IDE storage devices. It's useful for comparing bandwidth across network transport and storage interfaces.
How to Use This Tool?
-
Enter the value in Virtual Tributary 6 (payload) units.
-
Select the target unit as IDE (PIO mode 3).
-
Click convert to get the equivalent data transfer rate.
Key Features
-
Converts data transfer rates from Virtual Tributary 6 (payload) to IDE (PIO mode 3) units.
-
Supports legacy telecommunications and storage interface units.
-
Browser-based and straightforward to use without requiring technical background.
Examples
-
5 Virtual Tributary 6 (payload) equals approximately 0.3378 IDE (PIO mode 3).
-
10 Virtual Tributary 6 (payload) equals approximately 0.6757 IDE (PIO mode 3).
Common Use Cases
-
Mapping legacy PDH circuits over SONET networks with VT6 containers.
-
Interfacing embedded systems with older IDE storage devices.
-
Comparing throughput for retrocomputing and legacy hardware performance testing.
Tips & Best Practices
-
Understand the theoretical nature of conversion rates due to protocol and hardware differences.
-
Use this tool mainly for approximate equivalencies rather than exact throughput.
-
Consider CPU-driven transfer limitations when working with IDE (PIO mode 3) units.
Limitations
-
Conversion represents theoretical bandwidths and excludes protocol overhead.
-
IDE (PIO mode 3) throughput is limited by lack of DMA and CPU involvement.
-
VT6 payloads are designed for synchronous network transport, so direct comparisons to storage transfer rates are approximate.
Frequently Asked Questions
-
What is Virtual Tributary 6 (VT6) used for?
-
VT6 is a SONET/SDH virtual tributary container that carries lower-rate plesiochronous payloads within a larger synchronous payload, used for grooming and multiplexing services over optical networks.
-
What does IDE (PIO mode 3) represent?
-
IDE (PIO mode 3) is a CPU-driven programmed I/O transfer mode for Parallel ATA/IDE devices, with a theoretical maximum throughput around 11.1 MB/s.
-
Why convert between VT6 and IDE (PIO mode 3)?
-
Conversions help understand throughput equivalency in systems that involve legacy telecommunications transport and historical storage device transfer modes.
