What Is This Tool?
This converter tool enables users to translate data transfer measurements from the legacy SCSI (Fast Ultra Wide) parallel interface to the STM-4 (signal) format used in optical transport networks. It helps correlate storage system transfer rates with telecommunications transport capacities.
How to Use This Tool?
-
Enter the value in SCSI (Fast Ultra Wide) units you wish to convert
-
Select the target unit STM-4 (signal)
-
Start the conversion process to obtain the equivalent STM-4 value
-
Use the results for network planning or system integration purposes
Key Features
-
Converts from SCSI (Fast Ultra Wide) to STM-4 (signal) data transfer units
-
Based on established conversion factor specific to these interfaces
-
Supports legacy storage and modern telecom integration planning
-
Browser-based and easy to use without installation
Examples
-
2 SCSI (Fast Ultra Wide) equals approximately 1.0288 STM-4 (signal)
-
0.5 SCSI (Fast Ultra Wide) converts to about 0.2572 STM-4 (signal)
Common Use Cases
-
Connecting internal hard drives or RAID controllers in older systems that utilize parallel SCSI interfaces
-
Planning high-throughput backups to tape libraries with legacy SCSI equipment
-
Integrating legacy enterprise storage devices with modern telecommunications SDH infrastructure
-
Aggregating legacy SCSI data rates into standardized optical network rates for interoperability
Tips & Best Practices
-
Use the conversion for planning and comparative purposes, not for direct hardware interfacing
-
Consider overhead and protocol differences that may affect actual throughput
-
Validate legacy system capabilities when integrating with modern SDH networks
-
Apply the tool when upgrading or correlating legacy and contemporary data transport equipment
Limitations
-
Conversion reflects theoretical maximum transfer capabilities, not exact throughput
-
SCSI (Fast Ultra Wide) is a legacy parallel interface incompatible with the STM-4 optical format
-
Results are conceptual and intended for planning rather than direct signal translation
-
Overhead and protocol variations can cause actual data rates to differ markedly
Frequently Asked Questions
-
Can this tool convert actual signal formats between SCSI and STM-4?
-
No, the tool converts data transfer rates conceptually; the physical signal formats are incompatible.
-
Why convert from SCSI (Fast Ultra Wide) to STM-4 (signal)?
-
To relate legacy storage transfer rates to modern optical network capacities for planning and integration.
-
Is the conversion factor exact for effective data throughput?
-
No, it represents theoretical maximum capabilities and does not account for overhead or protocol differences.
Key Terminology
-
SCSI (Fast Ultra Wide)
-
A legacy parallel Small Computer System Interface mode with a wider 16-bit bus and faster signaling, used to connect storage devices and controllers.
-
STM-4 (signal)
-
The Synchronous Transport Module level-4 in SDH, an optical transmission standard with a nominal line rate of 622.08 Mbit/s, used to multiplex and transport digital traffic.
-
Data Transfer Rate
-
The measure of how quickly data is transmitted from one device or network to another.
