What Is This Tool?
This converter transforms data transfer measurements from the E.P.T.A. 2 (payload) protocol-specific unit to the SCSI (Fast Wide) hardware interface unit. It is designed for users who need to compare application-level message payload sizes with physical data transfer rates in legacy systems.
How to Use This Tool?
-
Enter the numeric value representing the E.P.T.A. 2 (payload) measurement.
-
Select the source unit as E.P.T.A. 2 (payload) and the target unit as SCSI (Fast Wide).
-
Click the convert button to see the equivalent value in SCSI (Fast Wide).
-
Review the result to assess throughput and bandwidth relationships between protocols and interfaces.
Key Features
-
Converts E.P.T.A. 2 (payload) units defined by a specific data transfer protocol.
-
Provides conversion to SCSI (Fast Wide), a SCSI-2 interface mode for higher throughput.
-
Offers quick calculation based on established conversion rates.
-
Enables comparisons between message payloads and hardware data throughput.
-
Browser-based and easy to use with no installation required.
Examples
-
10 E.P.T.A. 2 (payload) converts to 0.48 SCSI (Fast Wide) (10 × 0.048).
-
50 E.P.T.A. 2 (payload) converts to 2.4 SCSI (Fast Wide) (50 × 0.048).
Common Use Cases
-
Measuring message sizes in the E.P.T.A. 2 protocol for throughput analysis.
-
Comparing protocol-level payloads to physical transfer rates in legacy storage systems.
-
Estimating bandwidth for servers using SCSI Fast Wide disk and tape drives.
-
Assisting development environments that implement or test E.P.T.A. 2 message limits.
Tips & Best Practices
-
Ensure you understand that E.P.T.A. 2 (payload) sizes vary across implementations due to non-standardization.
-
Use conversion results as approximate values since real throughput varies with device and environment specifics.
-
Consider protocol overhead and actual device performance when interpreting conversion outcomes.
Limitations
-
E.P.T.A. 2 (payload) lacks a universal standard; sizes depend on protocol specifics.
-
SCSI Fast Wide's maximum throughput is theoretical and influenced by hardware and cable conditions.
-
The conversion assumes linear scaling and does not capture protocol or encoding overhead or real-world transfer rate reductions.
Frequently Asked Questions
-
What does E.P.T.A. 2 (payload) represent?
-
It represents the amount of application data carried in a single message specific to the E.P.T.A. 2 data-transfer protocol and is defined by that protocol's specifications.
-
What is SCSI (Fast Wide)?
-
SCSI (Fast Wide) is a SCSI-2 interface mode with a 16-bit data bus and Fast timing that theoretically achieves up to 20 MB/s transfer speed.
-
Can I rely on this conversion for exact data transfer rates?
-
No, the conversion is approximate since E.P.T.A. 2 payload units lack standardization and SCSI throughput depends on physical and environmental factors.
Key Terminology
-
E.P.T.A. 2 (payload)
-
A protocol-specific unit indicating the user data size in a single E.P.T.A. 2 message, lacking external standardization.
-
SCSI (Fast Wide)
-
A SCSI-2 interface mode with Fast timing and a 16-bit wide bus enabling a theoretical throughput around 20 MB/s.
-
Data Transfer Rate
-
The speed at which data is transmitted between devices, often measured in megabytes per second (MB/s).
