What Is This Tool?
This converter transforms data transfer values measured in SCSI (Fast) units, a legacy parallel SCSI standard, into Virtual Tributary 2 (payload) units, which are containers designed for transporting 2.048 Mb/s PDH/E1 signals over SONET/SDH optical networks.
How to Use This Tool?
-
Enter the value in SCSI (Fast) units that you want to convert.
-
Select SCSI (Fast) as the source unit and Virtual Tributary 2 (payload) as the target unit.
-
Click convert to receive the equivalent data transfer rate in Virtual Tributary 2 payload units.
Key Features
-
Converts data transfer rates from Fast SCSI to Virtual Tributary 2 payload units.
-
Based on a standard conversion rate aligning legacy storage interfaces with synchronous optical transport.
-
Supports understanding and integration of legacy parallel SCSI data within modern telecom frameworks.
Examples
-
2 SCSI (Fast) equals 78.125 Virtual Tributary 2 (payload).
-
0.5 SCSI (Fast) converts to 19.53125 Virtual Tributary 2 (payload).
Common Use Cases
-
Integrating legacy parallel SCSI storage data rates into SONET/SDH optical networks.
-
Transporting high-speed data from storage devices over synchronous optical systems using circuit emulation.
-
Facilitating interoperability in data centers and industrial settings between older SCSI devices and modern transport infrastructure.
Tips & Best Practices
-
Use the tool to bridge legacy storage interface data into telecom-grade synchronous networks.
-
Be mindful that the Virtual Tributary 2 payload is fixed at 2.048 Mb/s when planning multiplexing.
-
Consider hardware limitations of legacy SCSI (Fast) interfaces during conversion applications.
Limitations
-
Conversion assumes constant rates and does not handle protocol overhead differences.
-
Physical constraints of legacy SCSI (Fast) hardware may restrict actual throughput.
-
Virtual Tributary 2 payload size is fixed, requiring care with fractional or non-integer data rates.
Frequently Asked Questions
-
What does 1 SCSI (Fast) equal in Virtual Tributary 2 (payload)?
-
One SCSI (Fast) unit corresponds to 39.0625 Virtual Tributary 2 payload units.
-
Can this converter handle protocol overhead differences?
-
No, the conversion assumes constant data rates and does not account for protocol overhead or signaling differences.
-
Why convert SCSI (Fast) data rates to Virtual Tributary 2 payloads?
-
To allow legacy parallel SCSI data to be transported over modern SONET/SDH optical networks using standardized virtual tributary containers.
Key Terminology
-
SCSI (Fast)
-
A legacy parallel SCSI bus extension improving data transfer speed up to about 10 MB/s by using faster signaling.
-
Virtual Tributary 2 (payload)
-
A SONET/SDH virtual tributary container sized to carry a 2.048 Mb/s PDH/E1 channel for transporting time-division multiplexed signals.
-
SONET/SDH
-
Synchronous optical network standards for multiplexing and transporting digital signals over optical fiber.
