What Is This Tool?
This tool helps convert data transfer rates between STS3 (signal), a SONET transmission signal used in telecommunications, and SCSI (Ultra-2), a parallel storage interface standard used for block storage devices. It facilitates translating network transport performance into corresponding SCSI data-transfer rates.
How to Use This Tool?
-
Enter the data transfer value in STS3 (signal) units
-
Select STS3 (signal) as the source unit and SCSI (Ultra-2) as the target unit
-
Click convert to obtain the equivalent SCSI (Ultra-2) data transfer rate
-
Review results to compare or integrate telecom transport with storage interface performance
Key Features
-
Supports conversion between STS3 (signal) and SCSI (Ultra-2) data rates
-
Clear definitions and use cases of both unit types
-
Calculates equivalent data transfer rates using a fixed conversion factor
-
Ideal for telecom, data center, and IT enterprise comparisons
-
Browser-based and easy to use without installation
Examples
-
1 STS3 (signal) equals 0.243 SCSI (Ultra-2)
-
5 STS3 (signal) equals 1.215 SCSI (Ultra-2)
Common Use Cases
-
Aggregating voice and data on backbone telecom links between central offices using STS3
-
Connecting enterprise disk arrays and RAID controllers with SCSI Ultra-2 interfaces
-
Comparing performance of SONET network links with parallel SCSI storage transfers
-
Attaching tape backup drives and removable media in data centers
-
Provisioning leased lines and interfacing high-speed network signals with storage devices
Tips & Best Practices
-
Use this tool for theoretical rate comparisons rather than exact throughput predictions
-
Understand that STS3 and SCSI protocols have different overhead influencing actual performance
-
Utilize the converter to integrate telecom network metrics with storage infrastructure planning
-
Cross-check conversion results with device specifications in mixed network-storage environments
Limitations
-
Conversion represents theoretical data rate equivalence, not actual throughput
-
STS3 is a telecom transmission signal, while SCSI Ultra-2 is a storage interface protocol
-
Does not account for protocol overhead, device-specific performance, or efficiency
-
Practical transfer speeds can vary due to network and hardware conditions
Frequently Asked Questions
-
What does 1 STS3 (signal) represent in data transfer terms?
-
1 STS3 (signal) represents a SONET transmission line with a rate of 155.52 megabits per second used in synchronous optical or electrical transport networks.
-
What is SCSI (Ultra-2) used for?
-
SCSI (Ultra-2) is a storage interface standard utilizing Low Voltage Differential signaling, often used to connect disk arrays, RAID controllers, and removable-media devices in enterprise environments.
-
Is this converter suitable for exact throughput measurement?
-
No, this converter provides theoretical equivalence between data transfer rates but does not reflect actual throughput due to protocol differences and overhead.
