What Is This Tool?
This converter tool allows users to translate data transfer measurements from SCSI (Ultra-2), a parallel hardware interface standard, to STM-1 (signal), a synchronous transport unit used in telecom networks. It helps bridge the gap between block storage interfaces and high-speed network transport signals.
How to Use This Tool?
-
Enter the amount in SCSI (Ultra-2) units you want to convert
-
Select SCSI (Ultra-2) as the source unit and STM-1 (signal) as the target unit
-
Click the convert button to see the equivalent value in STM-1 (signal)
-
Use the result to compare or plan data transfer capacities between storage and network equipment
Key Features
-
Converts data transfer units from SCSI (Ultra-2) to STM-1 (signal)
-
Based on established conversion rate: 1 SCSI (Ultra-2) equals 4.1152263374 STM-1 (signal)
-
Supports use cases relevant to data centers, network engineering, and telecom provisioning
-
Browser-based and easy to use for quick calculations
-
Facilitates integration between storage hardware and synchronous digital hierarchy signals
Examples
-
1 SCSI (Ultra-2) converts to approximately 4.115 STM-1 (signal)
-
2 SCSI (Ultra-2) converts to approximately 8.230 STM-1 (signal)
Common Use Cases
-
Connecting enterprise disk arrays and RAID controllers to servers using block-storage interfaces
-
Attaching tape backup drives and removable-media libraries in data-center setups
-
Provisioning 155.52 Mbit/s fiber backbone links in telecommunications
-
Aggregating lower-rate tributary circuits over synchronous digital hierarchy networks
-
Integrating legacy workstations and storage devices with telecom infrastructures
Tips & Best Practices
-
Ensure you understand the protocol differences between SCSI (hardware interface) and STM-1 (network signal) before interpreting results
-
Use this conversion primarily for bandwidth equivalence estimates rather than direct functional replacement
-
Apply this tool when planning or managing data transfer capacity across storage and telecom equipment
-
Verify the compatibility of devices when interfacing legacy storage systems with SDH-based networks
Limitations
-
Conversion reflects bandwidth equivalence, not functional interchangeability between SCSI and STM-1
-
SCSI is a hardware interface protocol, whereas STM-1 represents a synchronous transmission signal
-
Practical implementations require awareness of protocol layers and physical interface differences beyond data rate
-
This tool does not account for signaling or command protocol variations
Frequently Asked Questions
-
What does the conversion rate from SCSI (Ultra-2) to STM-1 (signal) represent?
-
It represents the equivalence in data transfer rates, showing how many STM-1 signals match the bandwidth of one SCSI (Ultra-2) interface.
-
Can I use this conversion tool to replace hardware interfaces directly?
-
No, the tool is intended to provide bandwidth equivalence and does not imply direct interchangeability between SCSI hardware and STM-1 transport signals.
-
Where is converting between SCSI (Ultra-2) and STM-1 signal most useful?
-
It is useful in data centers and network environments that integrate legacy storage systems with synchronous digital hierarchy telecommunications infrastructure.
Key Terminology
-
SCSI (Ultra-2)
-
A parallel Small Computer System Interface standard using Low Voltage Differential signaling for improved data transfer performance.
-
STM-1 (signal)
-
The basic transmission unit in the Synchronous Digital Hierarchy carrying synchronous framed signals at a rate of 155.52 Mbit/s.
-
Bandwidth Equivalence
-
A comparison metric showing equal data transfer capacity between different unit types, not implying direct protocol compatibility.
