What Is This Tool?
This converter helps translate data transfer capacities between Virtual Tributary 1 (payload), a sub-rate container in SONET/SDH optical transport networks, and SCSI (Ultra-2), a parallel SCSI standard used for high-performance storage and peripheral communication.
How to Use This Tool?
-
Enter the value in Virtual Tributary 1 (payload) units.
-
Select the target unit as SCSI (Ultra-2).
-
Click convert to see the equivalent data transfer rate in SCSI (Ultra-2).
Key Features
-
Converts data transfer units from Virtual Tributary 1 (payload) to SCSI (Ultra-2).
-
Supports understanding of throughput equivalences between optical transport and parallel SCSI protocols.
-
Offers quick and browser-based calculations for network and storage integration.
-
Includes practical examples for easy reference.
Examples
-
1 Virtual Tributary 1 (payload) equals 0.0024125 SCSI (Ultra-2).
-
10 Virtual Tributary 1 (payload) equals 0.024125 SCSI (Ultra-2).
Common Use Cases
-
Mapping DS1/T1 channels into SONET frames via VT1.5 for optical transport.
-
Integrating network optical payload data rates with parallel SCSI storage performance.
-
Managing environments that interface optical transport networks with storage peripherals.
Tips & Best Practices
-
Understand the differences in technology when converting between VT1 payloads and SCSI interfaces.
-
Use this converter for conceptual throughput comparisons, not direct signal compatibility.
-
Account for environmental factors such as latency and protocol overhead when planning data transfers.
Limitations
-
Conversion reflects throughput equivalence and does not imply direct hardware compatibility.
-
VT1 payloads are optimized for multiplexing low-bit-rate optical signals, while SCSI (Ultra-2) uses parallel bus protocols.
-
Physical interfaces and protocols require specialized hardware for actual data communication.
Frequently Asked Questions
-
What does Virtual Tributary 1 (payload) represent?
-
It is a sub-rate container within SONET/SDH frames used to carry lower-rate signals multiplexed into higher-rate optical streams.
-
What is SCSI (Ultra-2)?
-
SCSI (Ultra-2) is a parallel Small Computer System Interface standard using Low Voltage Differential signaling for improved data transfer performance.
-
Can I directly connect devices using this conversion ratio?
-
No, this conversion represents throughput equivalence and does not ensure direct signal compatibility without proper interfacing hardware.
