What Is This Tool?
This converter translates data transfer measurements from the Virtual Tributary 1 (signal) unit used in SONET/SDH telecom networks to the SCSI (Ultra-3) unit common in legacy parallel storage interfaces. It helps users understand and compare data rates between telecommunications signals and storage subsystem interfaces.
How to Use This Tool?
-
Enter the data transfer amount in Virtual Tributary 1 (signal) units
-
Select the target unit as SCSI (Ultra-3)
-
Click the convert button to obtain the equivalent value
-
Review the result which reflects the conversion based on a fixed ratio
-
Use the converted data for planning or analysis purposes
Key Features

Examples
-
10 Virtual Tributary 1 (signal) equals 0.0135 SCSI (Ultra-3)
-
100 Virtual Tributary 1 (signal) equals 0.135 SCSI (Ultra-3)
Common Use Cases
-
Carrying lower-rate circuits like DS1/T1 over higher-rate SONET/SDH links
-
Connecting enterprise hard drives and RAID controllers with legacy SCSI (Ultra-3) interfaces
-
Specifying compatibility and throughput for storage subsystems with parallel SCSI
-
Grooming and aggregating sub-rate services in SONET/SDH networks
-
Assessing interoperability between telecommunication transport signals and storage hardware
Tips & Best Practices
-
Consider the conversion as an approximate comparison of data rates between different technology types
-
Recognize that SCSI (Ultra-3) applies to older storage equipment, not newer systems
-
Use the tool mainly for planning, benchmarking, or educational insights
-
Be aware of potential protocol overheads and real-world throughput differences
-
Validate conversions against specific system requirements when designing solutions
Limitations
-
Conversion compares fundamentally different types of data transfer technologies
-
Does not account for protocol overhead or actual throughput variations
-
SCSI (Ultra-3) standard is outdated and limited to legacy storage devices
-
Not suitable for evaluating performance of modern storage or telecommunications equipment
-
Results should not be used as exact performance indicators
