What Is This Tool?
This unit converter enables users to convert data transfer measurements from SCSI (Fast Wide), a SCSI-2 interface mode with enhanced throughput, into E.P.T.A. 1 (signal), a vendor-specific unit used to count signaling events in proprietary systems.
How to Use This Tool?
-
Enter the value in SCSI (Fast Wide) units you want to convert.
-
Select SCSI (Fast Wide) as the source unit and E.P.T.A. 1 (signal) as the target unit.
-
Apply the conversion to view the equivalent number of signaling events.
-
Use the results for analyzing protocol activity or preparing system reports.
Key Features
-
Converts SCSI (Fast Wide) measurements to E.P.T.A. 1 (signal) units.
-
Uses a fixed conversion rate to translate data transfer rates into signaling event counts.
-
Supports legacy computing and proprietary telecom protocol applications.
-
Helps with protocol-level accounting, diagnostics, and billing purposes.
Examples
-
Convert 2 SCSI (Fast Wide) units to signaling events: 2 × 78.125 = 156.25 E.P.T.A. 1 (signal).
-
Convert 0.5 SCSI (Fast Wide) units: 0.5 × 78.125 = 39.0625 E.P.T.A. 1 (signal).
Common Use Cases
-
Connecting legacy disk drives and RAID controllers to assess data throughput.
-
Logging control or signaling messages in proprietary telecom or network protocols.
-
Measuring signaling event rates for performance monitoring and capacity planning.
-
Billing based on counts of signaling events rather than data volume transferred.
Tips & Best Practices
-
Verify hardware and environment factors to understand actual throughput variability.
-
Use the conversion results primarily for accounting and diagnostics, not direct byte measures.
-
Ensure correct unit selection to maintain accurate protocol-level event tracking.
-
Apply conversions within legacy or proprietary system contexts requiring such units.
Limitations
-
E.P.T.A. 1 (signal) is a vendor-specific, non-standard unit without direct byte-to-bit equivalence.
-
Actual SCSI (Fast Wide) throughput depends on hardware, cable type, and device negotiation.
-
Conversion is valid only via the provided fixed rate; no general universal formula applies.
Frequently Asked Questions
-
What does SCSI (Fast Wide) represent?
-
SCSI (Fast Wide) is a SCSI-2 interface mode using a 16-bit data bus and 10 MHz timing, providing a theoretical maximum throughput of 20 MB/s for certain implementations.
-
What is E.P.T.A. 1 (signal)?
-
E.P.T.A. 1 (signal) is a vendor-specific measure used to count signaling events or control messages within proprietary data-transfer systems.
-
Why convert from SCSI (Fast Wide) to E.P.T.A. 1 (signal)?
-
Conversion helps translate high-throughput data rates into counts of signaling events for protocol accounting, diagnostics, or billing in specific environments.
Key Terminology
-
SCSI (Fast Wide)
-
A SCSI-2 interface mode combining Fast timing at 10 MHz with a 16-bit wide data bus, enabling up to 20 MB/s throughput in single-ended implementations.
-
E.P.T.A. 1 (signal)
-
A vendor-specific unit used to count signaling events or control messages within proprietary data-transfer systems.
-
Data Transfer
-
The process or rate of moving data between devices or systems, measurable in units like MB/s or signaling events.
