What Is This Tool?
This converter translates data transfer rates between STM-1 (signal), a telecommunications backbone transmission unit, and SCSI (Ultra-2), a parallel interface for storage devices. It helps bridge telecom networks and storage systems by providing a conceptual bandwidth comparison.
How to Use This Tool?
-
Enter the STM-1 (signal) value you want to convert
-
Select STM-1 (signal) as the source unit and SCSI (Ultra-2) as the target unit
-
Click the convert button to see the equivalent SCSI (Ultra-2) value
Key Features
-
Converts STM-1 (signal) to SCSI (Ultra-2) based on data transfer rates
-
Easy-to-use interface for quick unit translation
-
Browser-based tool accessible without installation
-
Helps in integrating telecom backbone transmission with storage peripherals
Examples
-
1 STM-1 (signal) equals 0.243 SCSI (Ultra-2)
-
4 STM-1 (signals) equal 0.972 SCSI (Ultra-2)
Common Use Cases
-
Provisioning 155.52 Mbit/s backbone fiber links in telecom networks
-
Connecting enterprise disk arrays and RAID controllers to servers
-
Attaching tape backup drives and removable-media libraries in data centers
-
Bridging SDH and SONET systems and interfacing with parallel SCSI peripherals
Tips & Best Practices
-
Understand the conceptual nature of this conversion focused on data-transfer rates
-
Verify compatibility at the protocol and interface level beyond rate conversion
-
Use this tool primarily to compare bandwidths rather than for direct hardware interfacing
Limitations
-
Conversion reflects approximate equivalence of data rates, not protocol compatibility
-
Differences in signaling and interface types mean no direct interoperability
-
Real-world throughput may vary due to protocol overheads and hardware restrictions
Frequently Asked Questions
-
What does STM-1 (signal) represent?
-
STM-1 (signal) is the basic transmission unit of the Synchronous Digital Hierarchy, carrying a framed synchronous signal at 155.52 Mbit/s for telecom backbone networks.
-
Is the STM-1 to SCSI (Ultra-2) conversion exact?
-
No, the conversion provides a rough equivalence based on data transfer rates and does not imply protocol or interface compatibility.
-
Where is SCSI (Ultra-2) commonly used?
-
SCSI (Ultra-2) is used for connecting enterprise storage devices, such as disk arrays and tape backup drives, to servers in data-center environments.
Key Terminology
-
STM-1 (signal)
-
A basic transmission unit in Synchronous Digital Hierarchy carrying 155.52 Mbit/s synchronous framed signals for telecom backbone infrastructure.
-
SCSI (Ultra-2)
-
A parallel Small Computer System Interface standard using Low Voltage Differential signaling to connect storage peripherals with enhanced transfer rates.
-
Data Transfer Rate
-
The speed at which data is transmitted from one device or interface to another, commonly measured in megabits per second.
