What Is This Tool?
This unit converter helps transform data transfer values from OC3, a high-speed optical transmission rate, to SCSI (Fast Ultra), a parallel signaling mode used in storage and backup devices. It facilitates understanding and converting between telecommunications network speeds and local device throughput.
How to Use This Tool?
-
Enter a value in OC3 units that you want to convert.
-
Select SCSI (Fast Ultra) as the target unit for conversion.
-
Click the convert button to see the equivalent value in SCSI (Fast Ultra).
-
Use the output to compare or integrate network and storage throughput rates.
Key Features
-
Converts data transfer rates from OC3 to SCSI (Fast Ultra) accurately using the defined conversion factor.
-
Provides clear examples to illustrate the conversion process.
-
Supports users in aligning telecom bandwidth with storage and backup system speeds.
-
Browser-based and easy to use for IT professionals and network technicians.
Examples
-
1 OC3 equals 0.972 SCSI (Fast Ultra).
-
10 OC3 converts to 9.72 SCSI (Fast Ultra).
Common Use Cases
-
Backbone links between ISPs or regional points to manage aggregated Internet traffic.
-
Leased wide area network circuits used by enterprises to transport various network services.
-
Connecting high-performance hard-disk arrays and RAID controllers in data centers.
-
Linking tape drives and robotic libraries for efficient data backup solutions.
-
Aggregating multiple telecom circuits for long-haul and metropolitan fiber connections.
-
Attaching legacy peripherals like optical jukeboxes and video capture devices.
Tips & Best Practices
-
Ensure understanding of both OC3 and SCSI (Fast Ultra) units before conversion.
-
Use this tool to facilitate integration between network bandwidth and local storage systems.
-
Consider the approximation nature of the conversion due to differing technologies.
-
Apply conversion results to plan IT infrastructure focusing on compatibility and throughput needs.
Limitations
-
The conversion is approximate as OC3 measures optical network transmission rates, while SCSI (Fast Ultra) indicates parallel interface speeds on storage devices.
-
Protocol overhead, signal encoding differences, and physical layer technologies can affect real data transfer performance beyond the conversion factor.
Frequently Asked Questions
-
What is OC3 used for?
-
OC3 is an optical transmission rate used in synchronous optical networking for backbone links and aggregating lower-rate channels over fiber in telecom networks.
-
What devices use SCSI (Fast Ultra)?
-
SCSI (Fast Ultra) is used in high-performance hard-disk arrays, RAID controllers, tape drives, robotic tape libraries, and legacy high-bandwidth peripherals.
-
Why is the conversion only approximate?
-
Because OC3 measures optical network bandwidth while SCSI (Fast Ultra) measures parallel device interface speed, differences in protocols and physical layers affect exact data rates.
Key Terminology
-
OC3
-
An optical carrier level 3 transmission rate at 155.52 megabits per second used for synchronous optical networking and long-distance fiber transport.
-
SCSI (Fast Ultra)
-
A parallel SCSI signaling mode combining Fast and Ultra extensions to increase throughput and reduce latency for storage devices.
