What Is This Tool?

This converter allows you to convert data transfer measurements from STM-4 (signal), a standardized optical transmission rate in telecommunications, to SCSI (LVD Ultra160), a parallel storage interface bandwidth metric used in legacy computing environments.

How to Use This Tool?

  • Enter the value in STM-4 (signal) unit
  • Select STM-4 (signal) as the source unit and SCSI (LVD Ultra160) as the target unit
  • Click convert to obtain the equivalent data transfer rate in SCSI (LVD Ultra160)
  • Review the result and apply as needed for your planning or analysis

Key Features

  • Converts data transfer rates between STM-4 (signal) and SCSI (LVD Ultra160)
  • Supports telecom and legacy storage interface units
  • User-friendly interface for quick and accurate conversion
  • Browser-based tool requiring no installation

Examples

  • 2 STM-4 (signal) equals 0.972 SCSI (LVD Ultra160) using the conversion factor 1 STM-4 = 0.486 SCSI
  • 5 STM-4 (signal) equals 2.43 SCSI (LVD Ultra160) by multiplying the STM-4 value by 0.486

Common Use Cases

  • Comparing data throughput between optical transport networks and legacy storage devices
  • Planning network capacity and storage performance upgrades
  • Assessing compatibility between telecom infrastructures and storage I/O systems
  • Evaluating legacy backup systems and tape drive throughput for migration planning

Tips & Best Practices

  • Consider the difference between STM-4's optical line rate and SCSI’s sustained data throughput
  • Use conversions as approximate guides due to differing units and physical characteristics
  • Apply conversions primarily for planning or historical performance comparisons
  • Verify compatibility of units and devices when integrating telecommunications and storage systems

Limitations

  • STM-4 includes overhead in its rate while SCSI measures maximum sustained throughput, so values may not directly reflect usable bandwidth
  • Differences in unit types (Mbps vs. MB/s) and physical layer properties affect conversion accuracy
  • SCSI (LVD Ultra160) is a legacy standard, limiting its relevance to historical or planning contexts rather than new deployments

Frequently Asked Questions

What does STM-4 (signal) represent?
STM-4 (signal) is an optical transmission frame in the Synchronous Digital Hierarchy with a nominal line rate of 622.08 Mbit/s, used for managing and transporting digital traffic in telecom networks.

What is SCSI (LVD Ultra160) used for?
SCSI (LVD Ultra160) is a parallel interface standard for storage devices specifying a maximum sustained data transfer rate of up to 160 MB/s, commonly used in legacy storage systems.

Why should the conversion between STM-4 and SCSI be treated cautiously?
Because STM-4 includes overhead and measures optical signal rates, while SCSI measures storage throughput, and their differing units mean the conversion is approximate and context-dependent.

Key Terminology

STM-4 (signal)
A Synchronous Transport Module level‑4 in SDH with a nominal line rate of 622.08 Mbit/s, used to multiplex and transport digital traffic including payload and overhead.
SCSI (LVD Ultra160)
A parallel interface standard using Low Voltage Differential signaling that specifications a bandwidth of up to 160 MB/s for storage device data transfer.
Data Transfer Rate
The speed at which data is transmitted between devices, measured differently depending on the medium and protocol.
