What Is This Tool?
This tool helps convert data transfer units from STS3 (signal), a telecom digital transmission rate, to SCSI (Sync), a synchronous data transfer mode for storage devices. It facilitates comparison and translation of data rates between these different technologies.
How to Use This Tool?
-
Enter the value in STS3 (signal) unit you want to convert
-
Select STS3 (signal) as the source unit and SCSI (Sync) as the target unit
-
Click the convert button to see the equivalent data transfer rate in SCSI (Sync)
-
Review the results and use the values for planning or analysis
-
Refer to example conversions for guidance if needed
Key Features
-
Converts data transfer rates between STS3 (signal) and SCSI (Sync) units
-
Browser-based and simple to use with direct input and output
-
Supports use cases in telecommunications and storage system management
-
Provides example conversions for quick reference
-
Helps align data rates across different system architectures
Examples
-
1 STS3 (signal) equals 3.888 SCSI (Sync)
-
5 STS3 (signal) equals 19.44 SCSI (Sync)
Common Use Cases
-
Aggregating voice and data on backbone telecom links between offices
-
Managing high-throughput storage I/O for servers and RAID arrays
-
Comparing data rates between telecom and storage network equipment
-
Provisioning leased lines for enterprise or ISP interconnects
-
Integrating legacy SCSI devices with synchronous transfer modes
Tips & Best Practices
-
Understand that conversion assumes negotiated SCSI parameters remain consistent
-
Use this tool for comparative and planning purposes rather than exact performance metrics
-
Cross-check conversion results with actual device specifications when possible
-
Keep in mind the fixed rate nature of STS3 versus the negotiated SCSI transfer rates
-
Use examples to validate your input and output values
Limitations
-
Conversion approximates SCSI throughput based on negotiation parameters which can vary
-
STS3 is a fixed rate standard, SCSI (Sync) rates depend on negotiated clock and offset
-
Actual transfer speeds may differ due to device configurations and environment
-
Conversion should be used primarily for planning and analysis, not precise benchmarking
-
Does not account for asynchronous or other SCSI transfer modes
Frequently Asked Questions
-
What does STS3 (signal) represent?
-
STS3 is a SONET digital transmission signal with a line rate of 155.52 megabits per second used in telecom networks to multiplex multiple lower-rate channels.
-
What is SCSI (Sync) mode?
-
SCSI (Sync) is the synchronous transfer mode of the SCSI protocol where data is transferred in coordination with a negotiated clock for higher throughput.
-
Why is the conversion between STS3 and SCSI approximate?
-
Because STS3 has a fixed rate while SCSI (Sync) transfer rates depend on negotiated parameters, so the conversion is an estimate for comparison.
Key Terminology
-
STS3 (signal)
-
A SONET digital transmission signal with a line rate of 155.52 Mbps used for multiplexing in synchronous optical or electrical networks.
-
SCSI (Sync)
-
The synchronous transfer mode in the SCSI protocol where data moves in synchronization with a negotiated clock for improved throughput.
-
Conversion Rate
-
The factor used to translate quantities from one unit to another; here, 1 STS3 (signal) equals 3.888 SCSI (Sync).
