Key Features
-
Converts from SCSI (Fast Wide) to STM-1 (signal) with accurate conversion rate
-
Web-based and easy to use from any device
-
Supports conversions relevant for legacy data storage and telecom network integration
Examples
-
Convert 5 SCSI (Fast Wide) to STM-1 (signal): 5 × 1.0288065844 = 5.144 STM-1 (signal)
-
Convert 0.5 SCSI (Fast Wide) to STM-1 (signal): 0.5 × 1.0288065844 = 0.514 STM-1 (signal)
Common Use Cases
-
Translating data transfer capabilities between legacy SCSI storage devices and SDH telecommunications systems
-
Supporting integration of disk drives and RAID controllers with modern network backbones
-
Planning telecom network provisioning using STM-1 links
Tips & Best Practices
-
Use this converter for planning and comparisons rather than precise real-time measurements
-
Consider implementation factors like cable length and signaling type when evaluating SCSI throughput
-
Rely on standardized STM-1 rates for telecom network design and provisioning
Limitations
-
Actual SCSI (Fast Wide) throughput can vary due to hardware and implementation differences
-
STM-1 units have fixed, standardized rates that may not reflect specific network conditions
-
Conversion mainly serves comparative and planning purposes, not exact transfer measurement
Frequently Asked Questions
-
What is SCSI (Fast Wide)?
-
SCSI (Fast Wide) is a SCSI-2 interface mode combining 10 MHz Fast timing with a 16-bit data bus, designed for high-throughput connections in legacy storage systems.
-
What does STM-1 (signal) represent?
-
STM-1 (signal) is the basic transmission unit of SDH networks, carrying synchronous framed data at 155.52 Mbit/s and used in telecom fiber backbones.
-
Why convert from SCSI (Fast Wide) to STM-1 (signal)?
-
Conversion helps integrate and compare legacy storage transfer rates with modern telecom transmission units for system planning and interfacing.
