What Is This Tool?
This tool converts data transfer rates between STS3c (signal), a telecom optical transport standard, and SCSI (Ultra-2), a parallel storage interface. It helps users translate data rates to support interoperability and performance assessment between network communications and storage devices.
How to Use This Tool?
-
Enter the data transfer value in STS3c (signal) units
-
Select STS3c (signal) as the source unit and SCSI (Ultra-2) as the target unit
-
Click convert to see the equivalent rate in SCSI (Ultra-2)
Key Features
-
Converts from STS3c (Synchronous Transport Signal level 3, concatenated) to SCSI (Ultra-2)
-
Offers data rate conversion for telecommunications and storage interface applications
-
Browser-based and user-friendly interface for quick conversions
-
Supports commonly used telecom and parallel storage data transfer units
Examples
-
1 STS3c (signal) equals 0.243 SCSI (Ultra-2)
-
5 STS3c (signal) equals 1.215 SCSI (Ultra-2)
Common Use Cases
-
Provisioning telecom backbone circuits or leased lines at 155.52 Mbps
-
Comparing SONET signal rates with parallel SCSI storage interface speeds
-
Interconnecting high-bandwidth virtual circuits over SONET networks
-
Connecting enterprise storage devices like RAID controllers and tape backups in data centers
Tips & Best Practices
-
Use precise input values to ensure accurate conversions
-
Understand that this conversion is a theoretical approximation between differing standards
-
Consult protocol details when integrating telecom and storage systems for performance evaluation
Limitations
-
Represents only theoretical data rate equivalences between STS3c and SCSI (Ultra-2)
-
Does not account for protocol overhead, signal encoding, or hardware differences
-
Actual throughput may vary depending on device implementation and environment
Frequently Asked Questions
-
What does STS3c stand for?
-
STS3c is a Synchronous Transport Signal level 3, concatenated, representing a 155.52 Mbit/s electrical transport signal formed by concatenating three STS-1 channels.
-
What is the primary use of SCSI (Ultra-2)?
-
SCSI (Ultra-2) is used to connect enterprise storage devices like disk arrays and tape backup drives to servers using a parallel interface with improved signaling.
-
Can I use this conversion for exact performance measurement?
-
No, the conversion provides a theoretical approximation of data rates and does not reflect actual performance including protocol and hardware factors.
Key Terminology
-
STS3c (signal)
-
A SONET electrical transport signal formed by concatenating three STS-1 channels, offering a throughput of 155.52 Mbit/s as a single contiguous payload.
-
SCSI (Ultra-2)
-
A parallel Small Computer System Interface standard using Low Voltage Differential signaling for higher data transfer rates and longer cable lengths.
