What Is This Tool?
This converter translates data transfer rates from STS3c (payload) units, representing a SONET payload channel, to SCSI (Sync) units, which denote synchronous transfers in the SCSI protocol. It helps bridge data rate understanding between optical networking and storage device interfaces.
How to Use This Tool?
-
Enter the value in STS3c (payload) to convert
-
Select STS3c (payload) as the source unit
-
Choose SCSI (Sync) as the target unit
-
Initiate the conversion to get the equivalent transfer rate
-
Use results to match network and storage system data rates
Key Features
-
Converts rates between high-bandwidth SONET payloads and synchronous SCSI protocols
-
Supports data transfer rate conversions for telecommunications and IT storage contexts
-
Utilizes a fixed conversion ratio reflecting protocol speed relationships
-
Provides example calculations for practical understanding
-
Browser-based and straightforward unit-pair conversion
Examples
-
2 STS3c (payload) equals 7.5168 SCSI (Sync)
-
0.5 STS3c (payload) equals 1.8792 SCSI (Sync)
Common Use Cases
-
Translating backbone optical link speeds (OC-3) to storage device transfer rates
-
Configuring leased-line services requiring ~155 Mbps data rate references
-
Mapping ATM or frame relay signals within SONET to synchronous storage protocols
-
Determining data transfer speed compatibility between network and RAID systems
-
Negotiating transfer parameters for legacy SCSI devices in IT environments
Tips & Best Practices
-
Always verify unit selections before conversion to ensure accuracy
-
Use conversion results to guide system interoperability decisions
-
Remember that protocol overhead can influence actual data throughput
-
Consider device-specific negotiated parameters when applying rates
-
Apply conversions as a guideline rather than exact performance metrics
Limitations
-
Conversion assumes an ideal ratio based on data transfer rates
-
Actual throughput may differ due to framing and protocol overhead
-
Hardware differences and timing negotiations can affect effective speed
-
Does not account for varying negotiated clock periods or offsets in SCSI modes
-
Should not be used as the sole basis for performance evaluation
Frequently Asked Questions
-
What does STS3c (payload) represent?
-
STS3c (payload) is the contiguous payload container in SONET carrying high-bandwidth data at an approximate gross rate of 155.52 Mbps (OC-3).
-
How does SCSI (Sync) differ from asynchronous SCSI transfers?
-
SCSI (Sync) uses a negotiated clock for data transfer, providing more consistent timing and higher throughput compared to asynchronous methods.
-
Why convert between STS3c (payload) and SCSI (Sync)?
-
Conversion helps match data transfer rates between optical transport networks and storage systems to ensure interoperability and performance alignment.
Key Terminology
