Tips & Best Practices
-
Remember the conversion is based on raw bandwidth and excludes protocol overhead
-
Consider differences in data encoding and signaling when applying conversion results
-
Use this tool to aid planning but verify with specific system protocols and implementations
-
Keep in mind STM-64 is for optical transmission, while SCSI LVD Ultra80 focuses on local storage interfaces
Limitations
-
Conversion reflects raw transfer bandwidth without protocol overhead consideration
-
Direct one-to-one practical usage scenarios are limited due to different system purposes
-
Differences in encoding and signaling can affect real-world bandwidth equivalences
Frequently Asked Questions
-
What does SCSI (LVD Ultra80) represent?
-
It is a Low Voltage Differential variant of the Ultra2 SCSI interface with up to 80 MB/s raw transfer bandwidth on a 16-bit bus using 40 MHz synchronous transfers, used primarily in high-performance storage systems.
-
What is STM-64 (signal)?
-
STM-64 is a Synchronous Transport Module level-64 signal in SDH with a line rate near 10 Gbit/s, functionally equivalent to SONET OC-192/STS-192, used in carrier backbone and long-haul fiber networks.
-
Why convert between SCSI (LVD Ultra80) and STM-64?
-
Conversion helps map legacy storage interface bandwidths to modern carrier-grade optical rates, facilitating system integration and migration in data centers and telecom networks.
