What Is This Tool?
This converter translates data transfer rates from Virtual Tributary 2 (payload), a SONET/SDH virtual tributary container for carrying 2.048 Mb/s PDH/E1 channels, to SCSI (Ultra-3), a parallel SCSI interface standard used for block-level data transfers between hosts and storage devices.
How to Use This Tool?

5 Virtual Tributary 2 (payload) converts to 0.008 SCSI (Ultra-3)
-
10 Virtual Tributary 2 (payload) equals 0.016 SCSI (Ultra-3)
Common Use Cases
-
Translating legacy TDM/SONET data transfer rates to storage interface throughput
-
Evaluating compatibility between telecommunications transport and storage subsystem interfaces
-
Benchmarking parallel SCSI interface performance within data center environments
-
Designing and diagnosing systems that integrate both network transport and storage devices
Tips & Best Practices
-
Always verify the context of conversion since the units represent different technologies
-
Use the conversion values for comparison and benchmarking rather than direct interchangeability
-
Consider protocol overhead and device implementations when applying results
-
Combine this tool with other technical assessments for comprehensive system design
Limitations
-
The conversion reflects different technology standards with distinct data framing and signaling
-
Throughput equivalency does not guarantee hardware or protocol compatibility
-
Effective transfer rates can vary due to differences in protocol efficiency and device designs
-
Primarily intended for comparative or benchmarking use—not for direct hardware substitution
Frequently Asked Questions
-
What is a Virtual Tributary 2 (payload)?
-
It is a SONET/SDH virtual tributary sized to carry a 2.048 Mb/s PDH/E1 channel, used for mapping lower-rate time-division multiplexed signals into higher-rate optical frames.
-
What does SCSI (Ultra-3) refer to?
-
SCSI (Ultra-3) is a version of the parallel Small Computer System Interface standard, defining signaling and command framing for block-level data transfers between hosts and storage devices.
-
Can this conversion be used to directly interchange hardware?
-
No, the conversion is mainly for comparative and benchmarking purposes because the units represent different technologies with distinct protocols.
