What Is This Tool?
This unit converter facilitates the translation of data transfer values from SCSI (Fast Wide), a SCSI-2 interface mode with a 16-bit data bus, to SCSI (Ultra-3), a later parallel SCSI standard. It helps users compare and understand throughput differences between these two SCSI interface types common in legacy storage systems.
How to Use This Tool?
-
Enter the value representing the data transfer rate in SCSI (Fast Wide) units.
-
Select SCSI (Fast Wide) as the input unit and SCSI (Ultra-3) as the output unit.
-
Apply the conversion and review the resulting SCSI (Ultra-3) value.
-
Use the result to evaluate relative data transfer capabilities or interface compatibility.
Key Features
-
Converts data transfer rates between SCSI (Fast Wide) and SCSI (Ultra-3) units.
-
Provides a clear conversion formula based on standardized parallel SCSI specifications.
-
Supports benchmarking and compatibility assessments for legacy storage interfaces.
-
Browser-based and easy to use without additional software installations.
Examples
-
4 SCSI (Fast Wide) equals 0.5 SCSI (Ultra-3) based on the conversion rate.
-
8 SCSI (Fast Wide) equals 1 SCSI (Ultra-3) following the formula provided.
Common Use Cases
-
Connecting disk drives and RAID controllers in legacy servers to assess throughput improvements.
-
Attaching tape drives and backup systems where different parallel SCSI generations are involved.
-
Benchmarking interface compatibility and throughput for storage subsystem design and diagnosis.
Tips & Best Practices
-
Verify device negotiation and cable conditions as they impact actual data transfer rates.
-
Use this conversion for theoretical comparisons rather than guaranteed performance.
-
Consult storage subsystem documentation to confirm interface compatibility after conversion.
Limitations
-
Actual throughput depends on factors like cable quality, device negotiation, and bus termination.
-
The conversion represents theoretical maximum rates, not always achieved in practice.
-
Differences in signaling and bus management may affect interoperability despite numeric conversion.
Frequently Asked Questions
-
What does 1 SCSI (Fast Wide) equal in SCSI (Ultra-3)?
-
The conversion rate is 1 SCSI (Fast Wide) equals 0.125 SCSI (Ultra-3).
-
Can this conversion be used to guarantee device performance?
-
No, the conversion provides theoretical data transfer comparisons and does not guarantee sustained speeds.
-
Why is this conversion important for legacy storage systems?
-
It helps in benchmarking compatibility and understanding throughput differences when maintaining or upgrading storage interfaces.
Key Terminology
-
SCSI (Fast Wide)
-
A SCSI-2 interface mode combining Fast timing (10 MHz) with a 16-bit data bus, offering up to 20 MB/s theoretical throughput.
-
SCSI (Ultra-3)
-
A generation of parallel SCSI interface standards specifying signaling and bus management for block-level data transfers.
-
Data Transfer Rate
-
The speed at which data is moved from one device to another, measured here in terms of different SCSI interface units.
