What Is This Tool?
This converter allows you to translate data transfer measurements from Virtual Tributary 1 (payload), a sub-rate container in SONET/SDH networks, to SCSI (Fast Ultra Wide), a legacy parallel storage interface. It is designed to help users bridge data transport rates between modern optical payloads and older storage bus standards.
How to Use This Tool?

Examples
-
10 Virtual Tributary 1 (payload) converts to 0.04825 SCSI (Fast Ultra Wide).
-
100 Virtual Tributary 1 (payload) converts to 0.4825 SCSI (Fast Ultra Wide).
Common Use Cases
-
Mapping DS1/T1 channels into SONET frames using VT1.5 for fiber ring transport.
-
Grooming multiple low-rate circuits into a high-rate SONET/SDH payload for efficient bandwidth management.
-
Connecting internal hard drives or RAID controllers via legacy SCSI in older servers.
-
Performing high-throughput backups to tape using parallel SCSI interfaces.
-
Translating data transfer rates in telecom and enterprise storage environments for integration and performance assessment.
Tips & Best Practices
-
Use this converter for theoretical or comparative assessments rather than exact device throughput matching.
-
Consider protocol overhead and practical limitations of each technology when interpreting results.
-
Verify compatibility and device capabilities when integrating systems using these differing data formats.
-
Rely on this conversion primarily for analyzing interoperability between optical transport payloads and parallel SCSI storage.
Limitations
-
Conversion involves fundamentally different technologies: optical transport payload containers versus parallel storage bus interfaces.
-
Results are best suited for comparative or theoretical use, not for exact device performance predictions.
-
Does not account for protocol overhead or specific hardware throughput characteristics.
Frequently Asked Questions
-
What is a Virtual Tributary 1 (payload)?
-
It is a sub-rate container within SONET/SDH networks used to carry lower-rate signals multiplexed into a higher-rate optical transport frame.
-
What does SCSI (Fast Ultra Wide) represent?
-
SCSI (Fast Ultra Wide) is a legacy parallel Small Computer System Interface mode with a wider data bus and faster signaling for higher data transfer rates.
-
Why convert between these two units?
-
Conversion helps translate data rates between optical transport payloads and legacy storage interfaces for interoperability and performance comparisons.
