What Is This Tool?
This unit converter enables users to transform data transfer values from STS3c (payload), a high-bandwidth optical transport signal, into equivalent rates in SCSI (Ultra-2), a parallel storage interface standard. It supports telecommunications and data center applications by facilitating comparison and integration between network backbones and storage systems.
How to Use This Tool?
-
Enter the value in STS3c (payload) you wish to convert.
-
Select 'STS3c (payload)' as the input unit and 'SCSI (Ultra-2)' as the output unit.
-
Click the convert button to see the equivalent data transfer rate in SCSI (Ultra-2).
-
Review the output to assist with network or storage planning decisions.
Key Features
-
Converts data transfer units between STS3c (payload) and SCSI (Ultra-2).
-
Simple interface to input values and obtain equivalent measurements.
-
Supports network planning and storage system performance comparisons.
-
Browser-based and easy to use without installation.
-
Provides illustrative examples to demonstrate conversions.
Examples
-
1 STS3c (payload) equals 0.2349 SCSI (Ultra-2).
-
4 STS3c (payload) converts to 0.9396 SCSI (Ultra-2) by multiplying 4 × 0.2349.
Common Use Cases
-
Planning backbone optical links carrying Ethernet or IP circuits.
-
Assessing leased-line services requiring approximately 155 Mbps circuits.
-
Transporting ATM, frame relay, or similar client signals over SONET payloads.
-
Connecting enterprise storage arrays and RAID controllers to servers.
-
Integrating tape backup drives and removable-media systems within data centers.
-
Linking legacy high-performance workstations with parallel SCSI peripherals.
Tips & Best Practices
-
Use this conversion for high-level capacity planning rather than precise throughput measurement.
-
Consider overhead and signaling differences when interpreting results.
-
Apply the converter to compare optical network link speeds and storage interface performance.
-
Verify compatibility of equipment specifications beyond data transfer rates.
Limitations
-
Conversion approximates equivalence without accounting for protocol overhead or signaling variations.
-
Does not reflect actual throughput differences caused by hardware or environmental factors.
-
Intended primarily for system planning instead of exact performance evaluation.
Frequently Asked Questions
-
What does STS3c (payload) represent in this converter?
-
STS3c (payload) is a concatenated SONET payload container offering a contiguous transport channel with a gross line rate of 155.52 Mbps, used for high-bandwidth optical transport.
-
What is SCSI (Ultra-2) used for?
-
SCSI (Ultra-2) is a parallel interface standard using Low Voltage Differential signaling to connect storage devices like disk arrays and tape backups, supporting higher performance than earlier SCSI variants.
-
Why should I convert STS3c (payload) to SCSI (Ultra-2)?
-
Converting helps to understand and plan the equivalent data transfer rates between optical transport networks and storage interfaces, ensuring efficient integration and compatibility.
