What Is This Tool?
This converter helps translate data transfer rates from the STS3c (payload) unit used in SONET optical transport systems to the SCSI (Async) unit representing asynchronous data transfer in legacy SCSI devices. It allows comparison and analysis of differing transfer protocols and device speeds.
How to Use This Tool?
-
Enter the value in STS3c (payload) units that you want to convert.
-
Select the target unit as SCSI (Async) from the converter dropdown.
-
Submit to get the equivalent data transfer rate in SCSI (Async) units.
Key Features
-
Converts STS3c (payload) data rates to SCSI (Async) units accurately based on defined conversion rate.
-
Supports analysis of throughput differences between high-bandwidth optical links and asynchronous SCSI devices.
-
Provides clear usage scenarios relevant to telecommunications, legacy storage systems, and network engineering.
Examples
-
1 STS3c (payload) equals 12.528 SCSI (Async)
-
2 STS3c (payload) equal 25.056 SCSI (Async)
Common Use Cases
-
Analyzing backbone optical links carrying Ethernet or IP circuits through SONET networks.
-
Comparing optical network data rates with asynchronous SCSI device throughput for benchmarking.
-
Troubleshooting and configuring legacy asynchronous SCSI devices in computing or embedded systems.
Tips & Best Practices
-
Use the converter to compare effective data transfer rates rather than physical interface compatibility.
-
Remember that SCSI (Async) throughput varies with device response and bus arbitration, so treat conversions as approximate.
-
Consider overhead bytes in STS3c payload reducing the usable data rate below the nominal line rate.
Limitations
-
Conversion addresses only throughput rates, not protocol or physical interface compatibility.
-
Effective SCSI (Async) rates depend on response times and bus arbitration, causing variability.
-
STS3c payload data rate is slightly less than gross line rate due to SONET overhead bytes.
Frequently Asked Questions
-
What does STS3c (payload) represent?
-
STS3c (payload) is the concatenated SONET payload container that carries high-bandwidth client signals at a gross line rate of 155.52 Mbps, employed in backbone optical links.
-
What is SCSI (Async)?
-
SCSI (Async) refers to asynchronous data transfer mode in the SCSI protocol where data transfer is managed through request/acknowledge handshakes without a shared clock.
-
Why convert between STS3c (payload) and SCSI (Async)?
-
Converting helps compare and analyze effective data transfer rates between modern optical networks and legacy SCSI devices for benchmarking and system design.
Key Terminology
-
STS3c (payload)
-
A SONET payload container providing a contiguous transport channel at about 155.52 Mbps with overhead bytes affecting usable data rate.
-
SCSI (Async)
-
An asynchronous mode of SCSI protocol data transfer relying on request/acknowledge handshakes rather than synchronous clocking.
-
Conversion Rate
-
The factor used to convert STS3c (payload) units to SCSI (Async), specifically 1 STS3c (payload) equals 12.528 SCSI (Async).
