What Is This Tool?

This tool converts data transfer measurements from STM-4 (signal), an optical transmission standard used in telecommunication networks, to SCSI (Ultra-2), a parallel interface standard for storage devices. It helps bridge the gap between optical transport rates and storage interface speeds.

How to Use This Tool?

  • Enter the value in STM-4 (signal) units you want to convert
  • Select STM-4 (signal) as the source unit and SCSI (Ultra-2) as the target unit
  • Press the convert button to get the equivalent value in SCSI (Ultra-2)
  • Use the results to assess compatibility and performance between optical and storage systems

Key Features

  • Converts STM-4 (signal) to SCSI (Ultra-2) using a defined nominal conversion rate
  • Supports converting line rates from synchronous digital hierarchy to storage interface standards
  • Provides quick and easy calculation for telecommunications and data center applications
  • Browser-based tool requiring no installation
  • Helpful for comparing network bandwidth with storage transfer speeds

Examples

  • 1 STM-4 (signal) equals 0.972 SCSI (Ultra-2)
  • 10 STM-4 (signal) equals 9.72 SCSI (Ultra-2)

Common Use Cases

  • Aggregating voice, data, and leased circuits over optical backbone links in telecom networks
  • Interconnecting multiple STM-1 circuits within carrier transport infrastructure
  • Transporting wholesale Ethernet or ATM services across SDH environments
  • Connecting enterprise disk arrays and RAID controllers to servers using SCSI (Ultra-2)
  • Attaching tape backup systems and removable-media libraries in data centers
  • Linking legacy high-performance workstations with parallel SCSI peripherals

Tips & Best Practices

  • Understand the fundamental differences between optical transport protocols and storage interfaces before converting
  • Use conversions as nominal speed references rather than exact payload equivalences
  • Consider signaling types and physical medium differences affecting real-world throughput
  • Apply results cautiously when planning system integrations involving telecommunication and storage equipment

Limitations

  • Conversion reflects nominal speed equivalences, not direct data payload compatibility
  • Differences in framing, signaling, and latency influence actual throughput performance
  • Physical mediums between STM-4 optical networks and parallel SCSI interfaces vary greatly
  • This tool does not account for protocol variations or overhead beyond nominal rates

Frequently Asked Questions

What is STM-4 (signal) used for?
STM-4 (signal) serves as a standardized optical transmission frame in synchronous digital hierarchy networks, commonly used for regional or inter-city backbone links aggregating various traffic types.

What does SCSI (Ultra-2) connect?
SCSI (Ultra-2) connects enterprise storage devices like disk arrays and RAID controllers to servers, as well as tape backup drives and other peripherals in data center environments.

Can this conversion reflect exact data throughput?
No, the conversion provides nominal speed equivalence rather than exact data payload compatibility due to differences in protocols and signaling methods.

Key Terminology

STM-4 (signal)
A synchronous digital hierarchy optical transport frame with a line rate of 622.08 Mbit/s used to multiplex digital traffic including payload and overhead.
SCSI (Ultra-2)
A parallel Small Computer System Interface standard employing Low Voltage Differential signaling to enhance data transfer rates and cable lengths.
Data Transfer Rate
The speed at which data is transmitted from one unit or device to another, often measured in Mbit/s or similar units.
