What Is This Tool?
This converter translates data transfer rates from the legacy Fast SCSI interface to the modern STM-16 signal level used in synchronous digital hierarchy (SDH) networks. It helps compare and relate older SCSI data rates with high-capacity optical network line speeds.
How to Use This Tool?
-
Enter the value in SCSI (Fast) units you want to convert
-
Select STM-16 (signal) as the target unit
-
Click the convert button to see the equivalent STM-16 data transfer rate
-
Use the result to relate legacy parallel SCSI throughput to telecom signal capacities
Key Features
-
Converts Fast SCSI data transfer rates into STM-16 signal units accurately
-
Supports legacy storage and modern telecom network unit comparison
-
Browser-based and easy to use without installation
-
Useful for systems integrating old SCSI devices with optical network infrastructures
Examples
-
10 SCSI (Fast) equals 0.321502058 STM-16 (signal)
-
5 SCSI (Fast) equals 0.160751029 STM-16 (signal)
Common Use Cases
-
Converting legacy SCSI data rates for integration with telecom optical backbone links
-
Comparing parallel SCSI storage bus speeds with high-capacity STM-16 line rates
-
Data center interconnect scenarios involving legacy storage and modern SDH networks
-
Assessing throughput for RAID or disk-array systems interfaced with carrier networks
Tips & Best Practices
-
Remember that SCSI (Fast) is a legacy standard with much lower throughput than STM-16
-
Use this tool for conceptual conversions of data transfer rates rather than direct hardware compatibility
-
Ensure additional equipment is used for physical integration due to differing protocols
-
Validate conversion results within network design or data migration planning
Limitations
-
SCSI (Fast) throughput is limited to about 10 MB/s and cannot match STM-16's high rate
-
Conversion reflects conceptual rate equivalence, not physical device compatibility
-
Signal formats and protocols differ, requiring special conversion hardware for integration
Frequently Asked Questions
-
What does converting SCSI (Fast) to STM-16 (signal) represent?
-
It represents translating legacy parallel SCSI data transfer speeds into modern telecom optical line rates for comparative and integration purposes.
-
Can I directly connect devices using SCSI (Fast) and STM-16 signals?
-
No, due to differences in signal format and protocol, conversion hardware is necessary for physical interconnection.
-
Why is STM-16 much faster than SCSI (Fast)?
-
Because STM-16 is a modern SDH signal with a gross bit rate of 2.48832 Gbit/s, while SCSI (Fast) is a legacy parallel bus typically reaching around 10 MB/s.
Key Terminology
-
SCSI (Fast)
-
A legacy parallel SCSI bus enhancement that doubles the original SCSI throughput, typically to about 10 MB/s, used for connecting storage devices before high-speed serial interfaces became common.
-
STM-16 (signal)
-
A synchronous digital hierarchy (SDH) standardized signal with a gross bit rate of 2.48832 Gbit/s, used in telecom networks for carrying multiplexed digital channels over optical or electrical links.
-
Conversion Rate
-
The factor used to translate data transfer rates from SCSI (Fast) units to STM-16 (signal) units, which is approximately 1 SCSI (Fast) equals 0.0321502058 STM-16.
