What Is This Tool?
This converter allows users to convert data transfer values from the legacy SCSI (Fast Ultra Wide) interface to STS12 (signal), a SONET transport signal. It is designed for comparing and integrating legacy parallel SCSI data transfer rates with modern synchronous optical network standards.
How to Use This Tool?
-
Enter a data transfer value measured in SCSI (Fast Ultra Wide)
-
Select SCSI (Fast Ultra Wide) as the source unit and STS12 (signal) as the target unit
-
Click convert to obtain the equivalent data transfer rate in STS12 (signal)
-
Use the result to compare or integrate legacy SCSI-based systems with SONET infrastructure
Key Features
-
Converts data transfer units from SCSI (Fast Ultra Wide) to STS12 (signal)
-
Supports legacy and modern networking and storage performance comparisons
-
Straightforward multiplication-based conversion
-
Ideal for planning and integration in telecommunications and enterprise storage
-
Browser-based and easy to use without needing special software
Examples
-
2 SCSI (Fast Ultra Wide) converts to approximately 1.0288 STS12 (signal)
-
5 SCSI (Fast Ultra Wide) converts to approximately 2.5720 STS12 (signal)
Common Use Cases
-
Connecting internal hard drives or RAID controllers in older servers with parallel SCSI
-
High-throughput backups using legacy SCSI tape libraries
-
Relating performance of legacy SCSI systems to modern SONET network rates for planning
-
Telecommunications infrastructure design involving SONET rings and legacy storage
-
Integrating storage enclosures in enterprises using mixed legacy and modern systems
Tips & Best Practices
-
Use this tool primarily for comparative or planning purposes when integrating different systems
-
Remember that this conversion approximates data transfer capabilities, not exact throughput
-
Account for protocol overhead and signaling differences when interpreting results
-
Verify compatibility of interfaces before relying on converted values for technical decisions
Limitations
-
Conversion shows approximate equivalence in data rates, not exact physical unit conversion
-
Real throughput may vary due to protocol overhead and link efficiency differences
-
SCSI and STS12 represent different technologies, so conversion applies mainly to planning
-
Do not use converted values as direct substitutes for hardware or protocol specifications
Frequently Asked Questions
-
What does SCSI (Fast Ultra Wide) refer to?
-
It is a legacy parallel Small Computer System Interface mode with a wider data bus and faster signaling, used mainly in older storage controllers and devices.

What type of signal is STS12 (signal)?
-
STS-12 is a SONET synchronous transport signal with a line rate of 622.08 Mbit/s, used in optical networks for carrying multiplexed digital payloads and overhead.
-
Why convert from SCSI to STS12?
-
To relate legacy SCSI interface data transfer performance to modern optical network transport rates for better integration and infrastructure planning.
