What Is This Tool?
This tool converts data transfer rates from STS1 (payload), a SONET optical network payload capacity measure, to SCSI (Ultra-3), which represents a parallel storage interface data transfer unit. It helps bridge telecom transport with storage subsystem parameters.
How to Use This Tool?
-
Enter the value in STS1 (payload) you want to convert
-
Select STS1 (payload) as the source unit
-
Choose SCSI (Ultra-3) as the target unit
-
Click convert to get the equivalent SCSI (Ultra-3) data transfer value
-
Use the result for capacity planning or interface specification
Key Features
-
Converts between STS1 (payload) and SCSI (Ultra-3) data transfer units
-
Uses precise conversion factor based on known capacity equivalences
-
Supports integration tasks between optical networks and storage systems
-
Browser-based, easy to use with no installation required
-
Provides quick examples to illustrate conversions
Examples
-
10 STS1 (payload) equals 0.38671875 SCSI (Ultra-3)
-
50 STS1 (payload) equals 1.93359375 SCSI (Ultra-3)
Common Use Cases
-
Provisioning SONET circuits to transport data aligned with SCSI storage interfaces
-
Planning and managing capacity on telecom optical transport rings
-
Mapping tributary signals into payload envelopes for network design
-
Benchmarking or testing SCSI parallel interface performance in storage arrays
-
Connecting storage devices like RAID controllers and tape drives in data centers
Tips & Best Practices
-
Always verify unit selection before conversion to ensure accuracy
-
Use this tool to plan integration between telecom and storage systems
-
Consider additional interface or protocol factors outside raw rate conversions
-
Leverage the conversion examples to understand equivalent throughput scales
-
Use the conversion results in conjunction with system-level design assessments
Limitations
-
Conversion applies only to data transfer rates related to payloads and interface throughput
-
Does not reflect protocol overhead, error correction, or physical interface variations
-
Effective throughput may vary due to network latency and hardware constraints
-
Not intended for direct performance benchmarking without broader context
Frequently Asked Questions
-
What does STS1 (payload) represent?
-
STS1 (payload) refers to the user data capacity inside a SONET STS-1 frame, with a usable payload capacity of 50.112 Mbps.
-
What is SCSI (Ultra-3) used for?
-
SCSI (Ultra-3) denotes a generation of the Small Computer System Interface standard for parallel data transfers, commonly used with storage devices and RAID controllers.
-
Why convert from STS1 (payload) to SCSI (Ultra-3)?
-
This conversion facilitates integration and capacity planning between optical telecom networks and storage subsystem performance by translating data transfer units.
