What Is This Tool?
This tool converts data transfer rates from OC1, a base SONET optical transmission rate, to the asynchronous mode of SCSI data transfer. It is designed to help compare and benchmark the throughput of optical networks against legacy or embedded asynchronous SCSI devices.
How to Use This Tool?
-
Enter the value in OC1 units that you wish to convert.
-
Select OC1 as the source unit and SCSI (Async) as the target unit.
-
Click on the convert button to get the equivalent SCSI (Async) data transfer rate.
-
Review the result to assist with benchmarking or integration tasks.
Key Features
-
Simple online conversion between OC1 and SCSI (Async) data rates.
-
Supports comparison of optical carrier line rates and asynchronous SCSI throughput.
-
Based on the fixed conversion rate of 1 OC1 = 4.32 SCSI (Async).
-
Useful for telecommunications, legacy device benchmarking, and embedded system testing.
Examples
-
1 OC1 equals 4.32 SCSI (Async).
-
2 OC1 converts to 8.64 SCSI (Async).
Common Use Cases
-
Provisioning carrier-grade leased fiber links between service providers and enterprises using SONET networks.
-
Benchmarking and reporting throughput of legacy asynchronous SCSI devices such as hard drives or tape drives.
-
Troubleshooting SCSI bus timing and handshake issues in asynchronous mode.
-
Testing and configuring embedded or retrocomputing systems operating with asynchronous SCSI connections.
Tips & Best Practices
-
Understand that SCSI (Async) throughput varies based on device response and bus arbitration.
-
Use the converter primarily for conceptual or comparative analysis rather than exact performance matching.
-
Consider protocol overhead differences when interpreting conversion results.
Limitations
-
SCSI (Async) data rates fluctuate due to device-specific timing and handshake delays.
-
Equivalent nominal throughput does not guarantee identical sustained data transfer speeds.
-
Conversion is conceptual as the units represent different technologies with distinct operating modes.
Frequently Asked Questions
-
What does OC1 represent in data transfer?
-
OC1 is the base SONET optical transmission rate at 51.84 megabits per second, used for framing and multiplexing in synchronous optical networks.
-
How does SCSI (Async) differ from synchronous SCSI?
-
SCSI (Async) transfers data using request/acknowledge handshakes without a shared clock, so throughput varies with device response times and bus arbitration.
-
Is the conversion exact between OC1 and SCSI (Async)?
-
No, the conversion is conceptual since the units correspond to different technologies and asynchronous SCSI throughput depends heavily on device timing.
Key Terminology
-
OC1
-
The base SONET optical transmission rate of 51.84 megabits per second, representing an STS-1 electrical signal used in synchronous optical networking.
-
SCSI (Async)
-
The asynchronous data-transfer mode of the SCSI protocol that uses request/acknowledge handshakes instead of a shared clock to transfer data.
-
SONET
-
A synchronous optical networking protocol used for framing and multiplexing optical transmission rates.
