What Is This Tool?
This converter allows you to convert values from Virtual Tributary 2 (payload) units, which represent SONET/SDH data channels, into SCSI (Async) units, which represent asynchronous data-transfer modes of SCSI protocols. It helps relate legacy telecommunications data rates to asynchronous SCSI throughput metrics.
How to Use This Tool?
-
Enter the value in Virtual Tributary 2 (payload) units you want to convert.
-
Select the target unit as SCSI (Async).
-
Click convert to view the equivalent SCSI (Async) units.
Key Features
-
Converts Virtual Tributary 2 (payload) to SCSI (Async) accurately based on defined equivalence rates.
-
Browser-based and easy to use without installations.
-
Supports conversions relevant to telecommunication and legacy data storage protocols.
Examples
-
1 Virtual Tributary 2 (payload) equals about 0.1707 SCSI (Async) units.
-
5 Virtual Tributary 2 (payload) units correspond to roughly 0.8533 SCSI (Async) units.
Common Use Cases
-
Translating E1 circuit capacities in SONET/SDH networks to asynchronous SCSI throughput values.
-
Benchmarking legacy SCSI devices operating in asynchronous mode for performance comparison.
-
Supporting troubleshooting and configuration of embedded or retrocomputing systems using asynchronous SCSI connections.
Tips & Best Practices
-
Use this conversion to assist in system integration between telecommunications and data storage equipment.
-
Combine with hardware-specific knowledge as actual performance depends on device response times and bus arbitration.
-
Apply it for compatibility analysis rather than precise performance measurement.
Limitations
-
Conversion only reflects abstract data rate equivalence, excluding device-specific delays and overhead.
-
It does not encompass error correction, bus contention, or timing factors inherent in asynchronous SCSI transfers.
-
Actual throughput may vary widely depending on hardware and network conditions.
Frequently Asked Questions
-
What does a Virtual Tributary 2 (payload) represent?
-
It is a SONET/SDH virtual tributary container sized to carry a 2.048 Mb/s PDH/E1 channel, used for mapping lower-rate TDM signals into higher-rate optical frames.
-
How does SCSI (Async) data transfer operate?
-
SCSI (Async) uses asynchronous request/acknowledge handshakes rather than a shared clock, so throughput depends on device response and bus arbitration.
-
Why convert between Virtual Tributary 2 (payload) and SCSI (Async)?
-
Converting these units helps benchmark, integrate, and compare legacy telecommunication circuits with asynchronous SCSI data rates in storage and embedded systems.
