What Is This Tool?
This tool allows users to convert data transfer values from STS3c (payload), a SONET optical transport payload measurement, to SCSI (Fast Wide), a legacy storage interface throughput standard. It facilitates understanding and translating bandwidth capacities between optical transport networks and storage subsystems.
How to Use This Tool?
-
Enter the amount in STS3c (payload) units you want to convert.
-
Select STS3c (payload) as the source unit.
-
Choose SCSI (Fast Wide) as the target unit.
-
Click the convert button to get the equivalent value in SCSI (Fast Wide).
-
Review the conversion result along with usage insights.

-
10 STS3c (payload) converts to about 9.396 SCSI (Fast Wide).
Common Use Cases
-
Comparing high-speed optical payload capacity to legacy SCSI storage throughput.
-
Planning backbone optical links carrying Ethernet or IP circuits.
-
Integrating leased-line services for enterprise bandwidth needs around 155 Mbps.
-
Linking disk drives, RAID controllers, and external storage using SCSI Fast Wide.
-
Data center capacity planning bridging optical transport and storage subsystems.
Tips & Best Practices
-
Consider protocol overhead and device negotiation when applying conversions practically.
-
Use conversion rates to assist in planning but verify real-world throughput with hardware tests.
-
Understand the context of both measurement types for accurate infrastructure integration.
-
Leverage the tool for legacy system upgrades and network capacity assessments.
Limitations
-
SCSI (Fast Wide) theoretical throughput can be affected by cable length and device protocols.
-
STS3c (payload) includes SONET framing overhead, lowering actual usable bandwidth.
-
Converted values may not represent sustained transfer rates due to hardware and protocol differences.
Frequently Asked Questions
-
What does STS3c (payload) measure?
-
STS3c (payload) measures the concatenated payload container in SONET networks carrying high-bandwidth client signals with an approximate gross rate of 155.52 Mbps.
-
Why convert from STS3c (payload) to SCSI (Fast Wide)?
-
Converting helps relate optical network transport capacities to legacy storage interface throughputs for integration and planning.
-
Does the conversion rate guarantee actual transfer speed?
-
No, actual speeds depend on physical factors and protocol overhead that may reduce effective throughput.
Key Terminology
-
STS3c (payload)
-
A SONET payload container providing a contiguous transport channel with a gross line rate of 155.52 Mbps (OC-3) used for carrying high-bandwidth client signals.
-
SCSI (Fast Wide)
-
A SCSI-2 interface mode combining Fast timing at 10 MHz with a 16-bit data bus, offering theoretical throughput around 20 MB/s for storage device connections.
-
SONET Overhead
-
Framing and overhead bytes in SONET that reduce the actual usable payload below the gross line rate.
