What Is This Tool?
This converter allows users to translate data transfer measurements from the STS12 (signal) unit to the SCSI (Fast Ultra) unit. It facilitates understanding and comparing bandwidths used in telecommunications and server storage environments.
How to Use This Tool?
-
Enter the numerical value in STS12 (signal) to convert
-
Select SCSI (Fast Ultra) as the target unit
-
Click the convert button to view the equivalent value in SCSI (Fast Ultra)
Key Features
-
Converts data rates from STS-12 synchronous optical transport to Fast Ultra SCSI signalling units
-
Offers a simple browser-based interface requiring only input values and unit selection
-
Supports comparisons for system integration and performance assessment in diverse IT infrastructures
Examples
-
2 STS12 (signal) equals 7.776 SCSI (Fast Ultra) after conversion
-
0.5 STS12 (signal) converts to 1.944 SCSI (Fast Ultra)
Common Use Cases
-
Aggregating regional traffic in carrier or ISP backbone networks using OC-12/STS-12
-
Transporting framed payloads such as ATM, POS, and Ethernet over SONET infrastructures
-
Connecting high-performance hard disk arrays and RAID controllers with SCSI interfaces
-
Attaching tape drives and robotic libraries for backup solutions
-
Linking legacy peripherals including optical jukeboxes and video devices
Tips & Best Practices
-
Use this tool to compare bandwidths for system planning between SONET and SCSI devices
-
Consider differing protocol overheads and hardware conditions when interpreting results
-
Verify device and cable specifications as they impact actual throughput beyond nominal rates
Limitations
-
Conversion compares line-rate bandwidths from distinct technologies with unique protocols and overhead
-
Actual throughput and latency may differ depending on hardware and implementation details
-
SCSI speed depends on device specifics, cable conditions, and bus arbitration, unlike standardized STS12 line rates
Frequently Asked Questions
-
What does STS12 (signal) represent?
-
STS-12 is a SONET transport signal with a synchronous line rate of 622.08 Mbit/s, used in optical networks for multiplexed digital payloads.
-
What is SCSI (Fast Ultra)?
-
SCSI (Fast Ultra) includes parallel signalling modes combining Fast and Ultra extensions to increase throughput and reduce latency while remaining SCSI-compatible.
-
Why convert between STS12 (signal) and SCSI (Fast Ultra)?
-
Conversion helps relate high-speed optical transfer rates to parallel SCSI throughput for integration, capacity planning, and performance comparison.
