What Is This Tool?
This tool allows users to convert data transfer values from Virtual Tributary 2 (signal), a telecom sub-rate signal format, to SCSI (Fast), a legacy parallel storage interface speed. It helps relate telecom throughput to legacy storage transfer rates.
How to Use This Tool?
-
Enter the number of Virtual Tributary 2 (signal) units you want to convert
-
Select the target unit as SCSI (Fast)
-
Click convert to see the equivalent SCSI (Fast) value using the given ratio
-
Review the result and use it to compare data transfer capabilities across systems
Key Features
-
Converts telecom data rates (VT2) to legacy SCSI (Fast) speeds
-
Shows conversion using the defined factor: 1 VT2 = 0.0288 SCSI (Fast)
-
Supports understanding between telecommunications and storage data transfer units
-
Includes example calculations for clarity
-
Browser-based and easy to use without additional software
Examples
-
2 Virtual Tributary 2 (signal) equals 0.0576 SCSI (Fast)
-
5 Virtual Tributary 2 (signal) equals 0.144 SCSI (Fast)
Common Use Cases
-
Transporting E1 circuits over SONET backbones in telecom networks
-
Configuring SONET multiplexers and digital cross-connects for PDH channels
-
Linking legacy storage devices using Fast SCSI in servers and workstations
-
Integrating telecom bandwidth measurements with legacy storage interface speeds
-
Supporting industrial or laboratory equipment with older SCSI peripherals
Tips & Best Practices
-
Ensure understanding that the conversion relates throughput comparison and not direct interchangeability
-
Use the tool for planning or provisioning where telecom and legacy storage systems coexist
-
Apply example calculations to verify expected results
-
Consider context to determine if conversion is appropriate for your specific scenario
Limitations
-
Conversion is approximate due to differing protocols and usage contexts
-
Virtual Tributary 2 represents continuous telecom circuit throughput, while Fast SCSI is a parallel bus transfer rate
-
Units serve distinct technical roles and are not directly interchangeable beyond throughput comparison
Frequently Asked Questions
-
What does Virtual Tributary 2 (signal) represent?
-
It is a SONET/SDH sub-rate signal carrying a 2.048 Mbps payload, used for transporting E1 channels within higher-rate frames.
-
What is Fast SCSI used for?
-
Fast SCSI is a legacy parallel SCSI bus extension designed to increase data transfer rates between hosts and storage devices, commonly reaching about 10 MB/s.
-
Why convert Virtual Tributary 2 (signal) to SCSI (Fast)?
-
To translate telecom data transfer rates into equivalent legacy storage interface speeds, aiding integration or comparison between telecommunications and legacy storage systems.
