What Is This Tool?
This online converter transforms data transfer amounts measured in SCSI (Async), the asynchronous SCSI protocol data throughput, into STS3 (signal), the synchronous digital transmission unit used in SONET networks. It helps relate legacy SCSI asynchronous device speeds to modern synchronous telecom signal rates.
How to Use This Tool?
-
Enter the data transfer value measured in SCSI (Async) units into the input field.
-
Select 'SCSI (Async)' as the source unit and 'STS3 (signal)' as the target unit.
-
Click the convert button to compute the equivalent STS3 (signal) rate.
-
Review the output value to understand the corresponding synchronous transport signal rate.
Key Features
-
Converts SCSI (Async) throughput values to STS3 (signal) rates accurately based on provided conversion rates.
-
Supports benchmarking and troubleshooting legacy SCSI devices using asynchronous data transfer metrics.
-
Facilitates network capacity planning by translating asynchronous SCSI throughput into synchronous SONET signal units.
-
User-friendly interface requiring simple input of SCSI (Async) values to obtain STS3 (signal) equivalents.
Examples
-
Converting 10 SCSI (Async) results in approximately 0.7716 STS3 (signal).
-
Converting 20 SCSI (Async) gives roughly 1.5432 STS3 (signal).
Common Use Cases
-
Benchmarking throughput of legacy SCSI devices operating in asynchronous modes.
-
Troubleshooting handshake and timing issues on SCSI asynchronous buses.
-
Testing embedded or retrocomputing systems using asynchronous SCSI data transfers.
-
Calculating backbone telecom link capacities using STS3 signals from asynchronous SCSI data rates.
-
Provisioning leased lines and ISP interconnects correlating legacy system speeds to modern synchronous networks.
Tips & Best Practices
-
Always verify source data is measured in SCSI (Async) asynchronous mode for accurate conversion.
-
Use the tool for approximate conversions while considering protocol overhead and device-specific response variations.
-
Combine this conversion with network capacity planning for seamless integration between legacy and modern systems.
-
Keep in mind differences between asynchronous throughput and fixed synchronous line rates when interpreting results.
Limitations
-
Conversion is approximate since SCSI (Async) throughput depends on varied device response times and handshakes.
-
SCSI (Async) throughput is an effective speed metric, not a fixed physical line rate like STS3 (signal).
-
Direct conversions may not reflect protocol overhead or variations inherent in asynchronous SCSI communications.
Frequently Asked Questions
-
What does SCSI (Async) represent?
-
SCSI (Async) indicates the asynchronous mode of the SCSI protocol where data transfer happens via request/acknowledge handshakes with no shared clock.
-
What is an STS3 (signal)?
-
STS-3 (signal) is a synchronous digital transmission signal with a line rate of 155.52 Mbps used in SONET networks to multiplex multiple lower-rate channels.
-
Why is the conversion approximate?
-
Because SCSI (Async) throughput varies based on device response times and handshake delays, while STS3 (signal) is a fixed-rate synchronous line signal.
Key Terminology
-
SCSI (Async)
-
The asynchronous mode of the SCSI protocol where data transfer occurs through request/acknowledge handshakes without a shared clock.
-
STS-3 (signal)
-
A synchronous optical network digital transmission signal with a line rate of 155.52 Mbps used to carry multiple lower-rate signals.
-
Request/Acknowledge Handshake
-
A communication method in asynchronous data transfer where the sender requests and receiver acknowledges data transactions.
