What Is This Tool?
This converter facilitates the transformation of data transfer rates from the legacy SCSI (Fast Ultra Wide) interface to the Virtual Tributary 2 payload format used in SONET/SDH networks. It supports users needing to map older parallel SCSI throughput into standardized optical transport units.
How to Use This Tool?
-
Enter the amount in SCSI (Fast Ultra Wide) units you wish to convert
-
Select SCSI (Fast Ultra Wide) as the source unit and Virtual Tributary 2 (payload) as the target unit
-
Click the convert button to get the equivalent value in Virtual Tributary 2 payload units
Key Features
-
Converts legacy SCSI (Fast Ultra Wide) throughput to Virtual Tributary 2 (payload) units
-
Supports mapping of parallel SCSI data transfer rates into SONET/SDH virtual tributary channels
-
Enables integration of older storage and backup systems with modern optical communication infrastructures
-
Browser-based and easy to use without requiring installation
Examples
-
1 SCSI (Fast Ultra Wide) equals 156.25 Virtual Tributary 2 (payload)
-
2 SCSI (Fast Ultra Wide) equals 312.5 Virtual Tributary 2 (payload)
Common Use Cases
-
Connecting internal hard drives or RAID controllers in older servers using parallel SCSI
-
Performing high-throughput backups to tape libraries with legacy SCSI interfaces
-
Mapping legacy SCSI data rates into SONET/SDH virtual tributary channels for optical network transport
-
Upgrading legacy enterprise systems with parallel SCSI to integrate with modern optical communication infrastructures
Tips & Best Practices
-
Verify compatibility of legacy SCSI systems with modern optical networks before conversion
-
Use this conversion primarily to understand throughput equivalence rather than full protocol compatibility
-
Consider protocol overhead and hardware constraints that may affect actual data transfer performance
Limitations
-
The conversion rate is theoretical and based on maximum data transfer capabilities
-
Actual throughput may vary due to overhead, signal integrity, and hardware limitations
-
Only addresses throughput equivalence and does not include differences in timing, framing, or error correction
-
Applies mostly when integrating legacy parallel SCSI with synchronous optical transport networks
Frequently Asked Questions
-
What does SCSI (Fast Ultra Wide) represent?
-
It is a legacy parallel Small Computer System Interface mode with a wide 16-bit data bus and faster signaling to provide higher sustained throughput for storage connections.
-
What is a Virtual Tributary 2 (payload)?
-
It is a SONET/SDH virtual tributary container sized to carry a 2.048 Mb/s PDH/E1 channel used in mapping lower-rate TDM signals into higher-rate optical frames.
-
Why convert from SCSI (Fast Ultra Wide) to Virtual Tributary 2 (payload)?
-
To translate legacy high-throughput SCSI data transfer rates into standard SONET/SDH channels, aiding integration of legacy storage systems with optical networks.
