What Is This Tool?
This unit converter allows you to convert data transfer rates from STM-1 (signal), a telecommunications backbone unit, to SCSI (Fast Ultra Wide), a legacy parallel storage interface mode. It helps compare and translate data rates between network transmission signals and storage bus performance.
How to Use This Tool?
-
Enter the value in STM-1 (signal) that you want to convert
-
Select STM-1 (signal) as the source unit and SCSI (Fast Ultra Wide) as the target unit
-
Click the convert button to see the equivalent SCSI (Fast Ultra Wide) value
Key Features
-
Converts data transfer units from STM-1 (signal) to SCSI (Fast Ultra Wide)
-
Provides precise conversion using the fixed rate 1 STM-1 = 0.486 SCSI
-
Ideal for telecom and legacy storage interface comparisons
-
Browser-based and easy to use without complex setup
Examples
-
2 STM-1 (signal) converts to 0.972 SCSI (Fast Ultra Wide)
-
0.5 STM-1 (signal) converts to 0.243 SCSI (Fast Ultra Wide)
Common Use Cases
-
Provisioning telecom fiber links operating at 155.52 Mbit/s
-
Comparing telecom backbone data rates to legacy storage throughput
-
Planning IT infrastructure migrations involving both SDH networks and parallel SCSI storage
-
Benchmarking performance between network transmission and storage devices
Tips & Best Practices
-
Use this converter for nominal data rate comparisons only, not precise performance metrics
-
Be aware that real-world transfer rates may vary due to technology-specific overhead
-
Keep in mind that SCSI (Fast Ultra Wide) is a legacy interface and not a standard measurement unit
-
Verify conversion results with actual device specifications when possible
Limitations
-
This conversion is based on nominal data-transfer rates and does not account for protocol or overhead differences
-
SCSI (Fast Ultra Wide) is not a formal SI unit but denotes an interface performance level
-
Actual throughput may differ because of bus contention, signaling specifics, and hardware constraints
-
Converter does not measure or simulate real device performance or protocol efficiency
Frequently Asked Questions
-
What does STM-1 (signal) represent?
-
STM-1 (signal) is the basic transmission unit in the Synchronous Digital Hierarchy, carrying data at a gross bit rate of 155.52 Mbit/s, widely used in telecom backbone networks.
-
Is SCSI (Fast Ultra Wide) a standard measurement unit?
-
No, SCSI (Fast Ultra Wide) refers to a legacy parallel storage interface mode indicating its transfer capability, not a formal SI unit.
-
Why would I convert STM-1 data rates to SCSI rates?
-
Conversion helps compare telecommunications fiber optic backbone speeds to legacy storage interface throughputs, useful in infrastructure migration and performance assessment contexts.
Key Terminology
-
STM-1 (signal)
-
The basic transmission unit in SDH networks carrying a synchronous framed signal at 155.52 Mbit/s.
-
SCSI (Fast Ultra Wide)
-
A legacy parallel Small Computer System Interface mode representing the transfer capability of wide, fast bus signaling used for storage devices.
-
Data Transfer Rate
-
The amount of data transmitted over a network or interface per unit of time, usually measured in bits per second.
