What does SCSI (Async) mean?

It denotes the asynchronous data-transfer mode of the SCSI protocol where data is transferred using request/acknowledge handshakes without a shared clock.

SCSI (Sync) is the synchronous data-transfer mode where data transfers are synchronized with a negotiated clock, enabling higher throughput and consistent timing.

How is the conversion rate between SCSI (Async) and SCSI (Sync) defined?

1 SCSI (Async) equals 0.3 SCSI (Sync), reflecting relative throughput effectiveness between asynchronous and synchronous modes.

What Is This Tool?

This converter allows you to convert data transfer measurements from SCSI (Async), an asynchronous transfer mode, to SCSI (Sync), a synchronous transfer mode. It helps evaluate or upgrade transfer rates by applying a defined conversion factor between these two SCSI protocols.

How to Use This Tool?

Enter the data transfer value in SCSI (Async) units
Select SCSI (Async) as the input unit and SCSI (Sync) as the output unit
Click convert to obtain the equivalent SCSI (Sync) transfer rate
Interpret converted results to assess performance improvements or device capabilities

Key Features

Converts data transfer values from SCSI (Async) to SCSI (Sync)
Uses a fixed conversion rate reflecting throughput differences
Supports applications in legacy system troubleshooting and storage optimization
Browser-based tool with straightforward input and output

Examples

Converting 5 SCSI (Async) units yields 1.5 SCSI (Sync) units
Converting 10 SCSI (Async) units results in 3 SCSI (Sync) units
Use the formula: 1 SCSI (Async) = 0.3 × SCSI (Sync) for manual calculations

Common Use Cases

Benchmarking or reporting throughput for legacy asynchronous SCSI devices
Troubleshooting timing and handshake issues on the SCSI bus
Configuring embedded or retrocomputing systems using asynchronous SCSI
Evaluating synchronous transfer modes for high-throughput server storage
Optimizing RAID controller and storage array performance with synchronous SCSI

Tips & Best Practices

Verify device support for synchronous transfer before conversion
Use conversion results as a guide rather than exact performance metrics
Consider negotiation parameters like clock period and offset for accurate SCSI (Sync) rates
Apply conversions when upgrading or troubleshooting legacy SCSI systems

Limitations

The conversion rate shows relative throughput but excludes hardware and environment specifics
Synchronous transfers require proper clock negotiation and device compatibility
Asynchronous devices cannot be converted to synchronous mode without hardware or firmware changes

Frequently Asked Questions

What does SCSI (Async) mean?: It denotes the asynchronous data-transfer mode of the SCSI protocol where data is transferred using request/acknowledge handshakes without a shared clock.
What is SCSI (Sync)?: SCSI (Sync) is the synchronous data-transfer mode where data transfers are synchronized with a negotiated clock, enabling higher throughput and consistent timing.
How is the conversion rate between SCSI (Async) and SCSI (Sync) defined?: 1 SCSI (Async) equals 0.3 SCSI (Sync), reflecting relative throughput effectiveness between asynchronous and synchronous modes.

Key Terminology

SCSI (Async): Asynchronous transfer mode using request/acknowledge handshakes without a shared clock, impacting throughput based on device and bus timing.
SCSI (Sync): Synchronous transfer mode with data synchronized to a negotiated clock, enabling more consistent transfer rates and timing.
Conversion Rate: A factor indicating the relationship between SCSI (Async) and SCSI (Sync) transfer measurements, defined as 1 SCSI (Async) = 0.3 SCSI (Sync).
