What does SCSI (Ultra-3) represent?

SCSI (Ultra-3) is a parallel storage interface standard defining signaling and data transfers between hosts and storage devices, used in legacy storage systems and data center backups.

What is STS3 (payload)?

STS3 (payload) refers to the user-data portion in a SONET STS-3 frame used for carrying client traffic over telecom transport channels like OC-3 circuits.

Why convert between SCSI (Ultra-3) and STS3 (payload)?

Converting between these units helps translate storage interface throughput into equivalent carrier-grade transport payload rates for interoperability and network capacity planning.

Examples

1 SCSI (Ultra-3) equals 8.51426 STS3 (payload).
5 SCSI (Ultra-3) equals 42.57131 STS3 (payload).

Common Use Cases

Connecting enterprise hard drives and RAID controllers in legacy storage arrays.
Provisioning and capacity planning for SONET OC-3 carrier backbone links.
Assessing compatibility and throughput between storage subsystems and telecom transport channels.
Benchmarking parallel SCSI interfaces and translating throughput rates for network design.

Tips & Best Practices

Use the converter for throughput estimation rather than exact data volume comparisons.
Consider protocol overhead and framing differences when interpreting conversion results.
Apply this tool mainly in environments using legacy Ultra-3 SCSI and SONET OC-3 standards.
Verify results alongside other network and storage performance metrics if needed.

Limitations

Conversion is approximate due to protocol overhead and framing differences between SCSI and SONET.
Not suitable for precise data volume calculations—best for throughput estimation.
Ultra-3 SCSI and SONET OC-3 technologies are considered legacy and less relevant in modern high-speed networks.
Differences in transfer mechanisms can limit direct comparability.
