What Is This Tool?
This converter enables you to translate data transfer rates between OC3, a high-speed optical carrier used in telecommunications, and Fast SCSI, an older parallel interface for storage devices. It assists users in comparing and planning data throughput across these distinct technologies.
How to Use This Tool?
-
Enter the numerical value representing the amount in OC3 units.
-
Select OC3 as the source unit and SCSI (Fast) as the target unit.
-
Execute the conversion to get the equivalent data transfer rate in Fast SCSI units.
-
Use the results to compare or plan capacity between optical networks and legacy storage devices.
Key Features
-
Converts data transfer units between OC3 and Fast SCSI (parallel SCSI bus).
-
Uses a precise conversion rate based on their relative transfer capacities.
-
Helps understand throughput differences between modern telecom links and legacy storage interfaces.
-
Browser-based tool requiring no installation for easy access.
-
Supports planning for mixed network and storage environments.
Examples
-
2 OC3 equals 3.888 SCSI (Fast).
-
0.5 OC3 equals 0.972 SCSI (Fast).
Common Use Cases
-
Comparing backbone optical link speeds to legacy storage device throughput.
-
Planning integration of high-speed telecom circuits with older SCSI-based systems.
-
Supporting infrastructure upgrades involving both modern networks and legacy storage equipment.
Tips & Best Practices
-
Confirm the conversion is for conceptual understanding rather than direct hardware compatibility.
-
Use this tool primarily when working with legacy systems alongside modern telecom infrastructures.
-
Remember the conversion reflects different technology contexts and is not a direct data transfer equivalence.
-
Combine conversion results with knowledge of device specifications for accurate system planning.
Limitations
-
OC3 and Fast SCSI come from fundamentally different transmission technologies and contexts.
-
Direct data transfer compatibility between OC3 and Fast SCSI devices is not practical.
-
Fast SCSI throughput is significantly lower than OC3 optical bandwidth.
-
This conversion mainly serves legacy system support and historical comparison purposes.
Frequently Asked Questions
-
What does OC3 represent in this conversion?
-
OC3 is an optical transmission rate of 155.52 megabits per second used in synchronous optical networking, mainly for backbone data transport.
-
What is Fast SCSI used for?
-
Fast SCSI is a legacy parallel interface used to connect storage devices like hard drives and tape drives to servers, primarily before faster serial interfaces were developed.
-
Is this conversion suitable for direct hardware connection?
-
No, OC3 and Fast SCSI operate on different technologies, so this conversion is conceptual and not for direct device interconnection.
Key Terminology
-
OC3
-
An optical carrier level 3 used in synchronous optical networking with a transfer rate of 155.52 megabits per second.
-
Fast SCSI
-
A parallel SCSI bus extension that doubles the original SCSI transfer rate, providing about 10 MB/s throughput in legacy storage systems.
-
SONET
-
Synchronous Optical Networking, a standardized protocol for transferring multiple digital bit streams over optical fiber.
