What Is This Tool?
This converter helps you change data transfer values from OC3, a high-speed optical carrier rate, to SCSI (Fast Wide), a legacy storage interface mode. It supports comparing network backbone rates with storage bus speeds for performance planning and integration.
How to Use This Tool?
-
Enter the value in OC3 units you want to convert.
-
Select OC3 as the source unit and SCSI (Fast Wide) as the target unit.
-
Click convert to view the equivalent value based on the conversion rate.
-
Review examples and use the results for comparing data transfer capacities.
Key Features
-
Converts data transfer rates between OC3 and SCSI (Fast Wide).
-
Based on the official conversion rate: 1 OC3 equals 0.972 SCSI (Fast Wide).
-
Supports understanding transfer capacities in both telecommunications and storage contexts.
-
Browser-based and easy to use without installation.
-
Provides examples for quick reference.
Examples
-
1 OC3 converts to approximately 0.972 SCSI (Fast Wide).
-
5 OC3 converts to approximately 4.86 SCSI (Fast Wide).
Common Use Cases
-
Backbone connections between ISPs or regional internet access points.
-
Leased wide-area network circuits for enterprises and telecommunications carriers.
-
Aggregating multiple lower-rate circuits for long-distance fiber links.
-
Connecting disk drives and RAID controllers to improve storage throughput.
-
Linking high-speed tape drives or removable storage devices in legacy systems.
-
Interfacing external storage enclosures and legacy SCSI peripherals.
Tips & Best Practices
-
Use the conversion to conceptually compare transfer rates across different technology domains.
-
Consider physical implementation factors when evaluating SCSI (Fast Wide) throughput.
-
Remember that OC3 is measured in megabits per second, while SCSI (Fast Wide) throughput is usually in megabytes per second.
-
Apply conversions to assist in integration and planning between networking and storage systems.
Limitations
-
SCSI (Fast Wide) throughput can vary substantially based on cable length and device negotiation.
-
OC3 rates and SCSI (Fast Wide) throughput use different units making direct comparisons complex without conversion.
-
Practical transfer speeds depend on many factors beyond nominal unit rates.
-
Conversion serves mainly for conceptual comparison rather than exact equivalence.
Frequently Asked Questions
