What Is This Tool?
This converter allows you to translate data transfer rates measured in SCSI (Sync) mode, common in high-throughput storage systems, into STS3c (signal) units used in telecommunications networks. It helps bridge storage I/O performance metrics with standard telecom bandwidth measurements.
How to Use This Tool?
-
Enter the value in SCSI (Sync) units you wish to convert
-
Select SCSI (Sync) as the source unit and STS3c (signal) as the target unit
-
Submit to obtain the equivalent rate in STS3c (signal)
Key Features
-
Converts synchronous SCSI data transfer rates to STS3c telecom signal rates
-
Browser-based and easy-to-use interface
-
Supports integration of storage and telecom data rate representations
-
Based on standardized conversion utilizing negotiated parameters and fixed SONET payload rates
Examples
-
2 SCSI (Sync) equals 0.5144032922 STS3c (signal)
-
10 SCSI (Sync) equals 2.572016461 STS3c (signal)
Common Use Cases
-
Mapping storage subsystem throughput to SONET network bandwidth for integration
-
Provisioning telecom leased-line circuits based on storage I/O performance data
-
Engineering systems where storage interfaces must connect with SONET transport infrastructure
Tips & Best Practices
-
Ensure the SCSI transfer mode is synchronous and negotiated for accurate conversion
-
Use the tool for planning and integrating storage data rates with telecom bandwidth allocations
-
Consider protocol overheads when interpreting converted values for real-world throughput
Limitations
-
Conversion applies only to synchronous negotiated SCSI modes; asynchronous transfers are excluded
-
STS3c units reflect fixed SONET payload rates, actual throughput may differ due to overhead
-
Differences in encoding and protocol-specific details may affect direct rate equivalence
Frequently Asked Questions
-
What does SCSI (Sync) represent?
-
SCSI (Sync) indicates a synchronous transfer mode of the SCSI protocol where data is transferred in sync with a negotiated clock for higher throughput and stable timing.
-
What is STS3c (signal)?
-
STS3c (signal) is a SONET electrical transport signal representing a concatenated payload combining three STS1 channels, used for high-bandwidth telecom circuits at 155.52 Mbit/s.
-
Why convert between SCSI (Sync) and STS3c (signal)?
-
Converting these units helps integrate storage I/O transfer rates with telecom backbone bandwidth, aiding network provisioning and performance alignment.
Key Terminology
-
SCSI (Sync)
-
A synchronous transfer mode within the SCSI protocol where data moves in step with a negotiated clock between devices for enhanced throughput and timing.
-
STS3c (signal)
-
A SONET electrical transport signal formed by concatenating three STS-1 channels, used to carry high-bandwidth payloads at 155.52 Mbps without interleaving.
-
Negotiated Parameters
-
Settings such as clock period and offset used in SCSI (Sync) mode to determine the effective data transfer rate.
