What does SCSI (Async) mean?

SCSI (Async) refers to the asynchronous data-transfer mode of the Small Computer System Interface protocol where data is exchanged via request/acknowledge handshakes without a shared clock.

OC1 is the base optical carrier transmission rate used in SONET networks, defined as 51.84 megabits per second.

Why convert SCSI (Async) to OC1?

Converting allows users to compare and integrate legacy SCSI device throughput data into modern optical networking capacities for planning and benchmarking.

Click convert to get the equivalent OC1 value based on the conversion rate.

Key Features

Converts data transfer units from SCSI (Async) to OC1 rates accurately using a standardized conversion factor.
Supports understanding asynchronous SCSI throughput in terms of synchronous optical carrier speeds.
Useful for benchmarking, troubleshooting, and network provisioning involving legacy and modern systems.

Examples

5 SCSI (Async) converts to approximately 1.1574 OC1.
10 SCSI (Async) converts to approximately 2.3148 OC1.

Common Use Cases

Benchmarking legacy SCSI devices running in asynchronous mode.
Troubleshooting compatibility and bus timing issues in SCSI systems.
Provisioning carrier-grade leased fiber circuits using optical carrier rates.
Designing optical backbone networks aggregating multiple lower-speed channels.
Testing embedded or retro systems integrating asynchronous SCSI with modern networks.

Tips & Best Practices

Always verify the device operating mode to confirm asynchronous SCSI use before converting.
Use the tool to approximate data rates to align legacy device performance with optical networking standards.
Consider the variability of asynchronous throughput when interpreting conversion results.

Limitations

SCSI (Async) throughput varies depending on device response and bus arbitration, causing approximate conversion results.
Conversion assumes average rates and may not reflect peak or minimum data transfer speeds.
OC1’s fixed optical rate may not fully capture the timing characteristics of asynchronous transfer modes.
