What Is This Tool?
This converter allows users to translate data transfer units between STM-1 (signal), a telecom backbone rate, and SCSI (Ultra-3), a storage interface standard. It helps in assessing compatibility and performance comparisons across networking and storage technologies.
How to Use This Tool?
-
Enter the value in STM-1 (signal) units that you want to convert
-
Select STM-1 (signal) as the input unit
-
Choose SCSI (Ultra-3) as the output unit
-
Click the convert button to see the equivalent SCSI (Ultra-3) value
Key Features
-
Converts data transfer values from STM-1 (signal) to SCSI (Ultra-3)
-
Provides standardized unit interpretation based on telecommunications and IT interface standards
-
Includes examples for easier understanding of conversion values
-
Useful for system design and benchmarking between network and storage data rates
Examples
-
1 STM-1 (signal) equals 0.1215 SCSI (Ultra-3)
-
10 STM-1 (signal) equals 1.215 SCSI (Ultra-3)
Common Use Cases
-
Provisioning backbone fiber links at 155.52 Mbit/s in telecom networks
-
Connecting enterprise storage devices and RAID controllers in legacy systems
-
Comparing throughput between telecom signals and parallel SCSI storage interfaces
-
Interfacing between SDH and SONET systems or evaluating backup system performance
Tips & Best Practices
-
Verify the units before converting to ensure accurate context
-
Use conversions to assess compatibility but consider protocol and hardware differences
-
Refer to multiple examples for better grasp of conversion scale
-
Use this tool as a guide rather than an absolute performance indicator
Limitations
-
Conversion approximates throughput capacity between differing technologies
-
Does not reflect protocol overhead or actual transfer efficiency
-
Performance varies with hardware, physical media, and interface specifics
Frequently Asked Questions
-
What does STM-1 (signal) represent?
-
STM-1 (signal) is the basic transmission unit of the Synchronous Digital Hierarchy, carrying data at a gross bit rate of 155.52 Mbit/s.
-
What is SCSI (Ultra-3) used for?
-
SCSI (Ultra-3) is a parallel storage interface standard used to connect hosts and storage devices for block-level data transfers.
-
Can I use this conversion for exact performance measurement?
-
No, this conversion is an approximate comparison of throughput capacities and does not account for protocol overhead or hardware variations.
Key Terminology
-
STM-1 (signal)
-
The basic transmission unit of the Synchronous Digital Hierarchy, carrying synchronous framed signals at 155.52 Mbit/s.
-
SCSI (Ultra-3)
-
A version of the Small Computer System Interface parallel storage standard used for block-level data transfers between hosts and storage devices.
-
Data Transfer Rate
-
The amount of data transmitted from one point to another within a specified time frame, often measured in bits per second.
