What Is This Tool?
This converter allows users to translate data transfer quantities from Virtual Tributary 6 (signal), a SONET sub-channel, into SCSI (Fast), an older parallel SCSI bus data rate. It supports comparison and integration of telecommunication transport signals with legacy storage interface speeds.
How to Use This Tool?
-
Enter the quantity in Virtual Tributary 6 (signal) units you wish to convert
-
Select Virtual Tributary 6 (signal) as the input unit
-
Choose SCSI (Fast) as the output unit
-
Click the convert button to see the equivalent SCSI (Fast) value
-
Use the results to compare or map SONET transport rates to legacy storage speeds
Key Features
-
Converts data transfer rates between Virtual Tributary 6 (signal) and SCSI (Fast)
-
Based on standardized definitions from SONET/SDH and legacy SCSI technology
-
Enables alignment of network transport channels with storage bus interfaces
-
Supports multiple example calculations for user clarity
-
Browser-based and easy to use without complex setup
Examples
-
1 Virtual Tributary 6 (signal) equals 0.0789 SCSI (Fast)
-
10 Virtual Tributary 6 (signal) units convert to 0.789 SCSI (Fast)
Common Use Cases
-
Mapping multiple lower-rate PDH/TDM circuits over a SONET network using VT6 channels
-
Traffic grooming and bandwidth allocation in SONET add/drop multiplexers
-
Integrating SONET/SDH transport channels with legacy parallel SCSI storage systems
-
Connecting industrial or laboratory equipment relying on older data transfer standards
-
Supporting early RAID or disk-array configurations using parallel SCSI interfaces
Tips & Best Practices
-
Verify the context of your data transfer before converting due to technology differences
-
Consider physical interface compatibility when applying conversions practically
-
Use this tool for theoretical comparisons rather than direct interoperability
-
Reference SONET/SDH and SCSI documentation for deployment details
-
Be mindful that SCSI (Fast) is a legacy interface with limited throughput
Limitations
-
Conversion reflects differences in technology and transfer methods, not direct compatibility
-
Practical use requires adaptation of encoding, protocols, and physical connections
-
SCSI (Fast) is an older interface with lower speeds compared to modern standards
-
Real-world interoperability between VT6 and SCSI (Fast) is limited
-
Results are for alignment and comparison, not plug-and-play use
Frequently Asked Questions
-
What is a Virtual Tributary 6 (VT6) signal?
-
A VT6 is a standardized logical sub-channel within the SONET family used to carry and multiplex lower-rate client signals through byte-interleaving in SONET/SDH transport.
-
What does SCSI (Fast) refer to?
-
Fast SCSI is an enhanced parallel SCSI standard that approximately doubles the original transfer rate to about 10 MB/s, commonly used in legacy storage systems.
-
Why convert between VT6 signals and SCSI (Fast)?
-
Users convert to align data transfer rates and capacities when integrating SONET network transport with older legacy parallel SCSI storage devices.
Key Terminology
-
Virtual Tributary 6 (VT6)
-
A SONET logical sub-channel enabling multiplexing of lower-rate signals inside an STS-1 payload for traffic grooming and transport.
-
SCSI (Fast)
-
A parallel SCSI enhancement providing approximately double the transfer rate of original SCSI, used for legacy storage device communication.
-
Data Transfer Rate
-
The speed at which data is transmitted from one device or system to another.
