Common Use Cases
-
Connecting legacy enterprise hard drives and RAID controllers in storage arrays
-
Interfacing tape drives and automated backup libraries in data centers
-
Benchmarking and designing storage subsystem compatibility with parallel SCSI
-
Aggregating regional traffic over carrier or metro fiber links using OC-12/STS-12
-
Transporting digital payloads like ATM or Ethernet over SONET infrastructure
-

Tips & Best Practices
-
Confirm unit selections before converting to ensure accurate results
-
Use the conversion for data rate equivalences only, understanding protocol differences
-
Apply conversions to support infrastructure planning between legacy storage and modern networks
-
Consult hardware documentation for compatibility when bridging different interface types
Limitations
-
Conversion reflects only transfer rate equivalences, not protocol overhead or latency differences
-
SCSI (Ultra-3) and STS12 represent different interface types with distinct hardware protocols
-
Direct interchangeability between interface types may be restricted by physical and protocol constraints
Frequently Asked Questions
-
What does the conversion from SCSI (Ultra-3) to STS12 (signal) represent?
-
It represents the equivalent data transfer rate between the parallel SCSI storage interface and the synchronous optical transport signal used in SONET networks.
-
Can this conversion tool be used for latency or protocol overhead comparisons?
-
No, the tool only addresses data transfer rate equivalences and does not account for latency or protocol overhead differences.
-
Is SCSI (Ultra-3) compatible with STS12 in hardware applications?
-
SCSI (Ultra-3) is a parallel storage interface, while STS12 is an optical transport signal; hardware compatibility between the two depends on specific protocol and physical interface considerations.
Key Terminology
-
SCSI (Ultra-3)
-
A generation of the Small Computer System Interface (SCSI) parallel storage standard specifying signaling and data transfer management between hosts and storage devices.
-
STS12 (signal)
-
A SONET synchronous transport signal with a line rate of 622.08 Mbit/s, carrying multiplexed payloads and overhead for optical network management.
-
Conversion Rate
-
The factor used to translate data transfer values from SCSI (Ultra-3) units to STS12 (signal) units, specifically 1 SCSI (Ultra-3) equals 2.0576131687 STS12 (signal).
