What does SCSI (Sync) mean?

SCSI (Sync) refers to the synchronous data transfer mode of the SCSI protocol using a negotiated clock to achieve consistent and higher throughput than asynchronous modes.

What is STM-4 (signal)?

STM-4 (signal) is a Synchronous Transport Module level‑4 optical frame used in SDH networks with a nominal line rate of 622.08 Mbit/s, carrying multiplexed digital traffic and overhead.

Why convert SCSI (Sync) rates to STM-4 (signal)?

Converting these units helps translate storage interface data rates into telecom transmission capacities, enabling interoperability between high-performance storage systems and optical network backbones.

Tips & Best Practices

Understand that these units originate from different technical domains, so compare metrics carefully
Use nominal values for planning rather than exact real-world throughput expectations
Consider protocol overhead and network conditions separately from this conversion
Verify negotiated clock parameters when working with SCSI (Sync) rates

Limitations

Conversion rates represent nominal values without accounting for protocol overhead or encoding differences
Unit definitions come from distinct domains, which may limit direct performance comparisons
Does not reflect real network or storage conditions that impact effective throughput
