What Is This Tool?
This unit converter helps you translate data transfer rates between the SCSI (Fast Wide) interface and the SCSI (Ultra-2) standard. It enables conversions relevant to IT, storage management, and legacy hardware interoperability.
How to Use This Tool?
-
Enter the amount in SCSI (Fast Wide) units you want to convert
-
Select SCSI (Fast Wide) as the input unit and SCSI (Ultra-2) as the output unit
-
Click the convert button to get the equivalent value in SCSI (Ultra-2)
-
Review the result which reflects the theoretical conversion rate
Key Features
-
Converts data transfer values from SCSI (Fast Wide) to SCSI (Ultra-2)
-
Supports legacy and modern parallel SCSI units with known conversion rates
-
Browser-based, simple input for quick conversions
-
Displays conversion results based on theoretical maximum rates
Examples
-
4 SCSI (Fast Wide) corresponds to 1 SCSI (Ultra-2)
-
8 SCSI (Fast Wide) equals 2 SCSI (Ultra-2)
Common Use Cases
-
Translating legacy SCSI-2 16-bit single-ended data rates into modern parallel SCSI standards
-
Supporting IT data centers that mix older and newer SCSI storage devices
-
Maintaining compatibility between legacy hardware and contemporary enterprise storage
-
Managing archival tape backup systems requiring translation between SCSI interfaces
Tips & Best Practices
-
Confirm device negotiation and cable quality to approach theoretical rates
-
Use this tool for estimating conversions rather than precise real-world throughput
-
Be aware that legacy SCSI limitations may affect actual performance and cable length support
Limitations
-
Conversion rates represent theoretical maximums, not guaranteed speeds
-
Actual throughput depends on signaling methods and physical implementation
-
Legacy single-ended SCSI may not support Ultra-2's longer cable capabilities
-
Device negotiation and cable characteristics influence achievable transfer rates
Frequently Asked Questions
-
What does the conversion rate between SCSI (Fast Wide) and SCSI (Ultra-2) represent?
-
It represents the theoretical maximum throughput translation where 1 SCSI (Fast Wide) equals 0.25 SCSI (Ultra-2). Actual speeds vary based on device and setup.
-
Can this converter improve actual data transfer speeds?
-
No, the tool only converts unit values. Actual improvement depends on hardware, cabling, and device negotiation.
-
Why is converting between these SCSI standards important?
-
Conversion facilitates interoperability and understanding between legacy equipment using SCSI-2 and modern systems using Ultra-2, especially in enterprise storage and backup environments.
Key Terminology
-
SCSI (Fast Wide)
-
A SCSI-2 interface mode combining 10 MHz timing with a 16-bit data bus to yield a max theoretical transfer of 20 MB/s in a single-ended implementation.
-
SCSI (Ultra-2)
-
A parallel SCSI standard using Low Voltage Differential signaling for improved transfer performance and longer cable lengths compared to earlier single-ended variants.
-
Low Voltage Differential (LVD)
-
An electrical signaling method used in SCSI (Ultra-2) that allows higher throughput and longer cable distances than single-ended signaling.
