Tips & Best Practices
-
Verify the protocol mode of your SCSI devices before converting
-
Use conversions to help diagnose performance or compatibility concerns in legacy storage systems
-
Interpret the results as effective data rate equivalences, not raw transfer speeds
-
Consider environmental and implementation factors impacting throughput
-
Apply the tool during design and benchmarking of storage subsystems to ensure proper interface compatibility
Limitations
-
Conversion rates vary depending on device implementation and bus arbitration delays
-
Does not represent simple transfer speeds but effective throughput equivalence under different signaling modes
-
Environmental factors can affect conversion accuracy
-
Specific to the protocols' mode differences within SCSI standards
Frequently Asked Questions
-
What does SCSI (Ultra-3) represent?
-
SCSI (Ultra-3) is a parallel SCSI standard generation specifying signaling, command framing, and bus management for block-level data transfers between hosts and storage devices.
-
How does SCSI (Async) data transfer work?
-
SCSI (Async) uses asynchronous request/acknowledge handshakes rather than a shared clock, with throughput depending on device response times and bus arbitration.
-
Why convert from SCSI (Ultra-3) to SCSI (Async)?
-
Converting helps understand performance differences between synchronous and asynchronous SCSI modes, aiding benchmarking, diagnosing, and configuration in legacy storage systems.
Key Terminology
-
SCSI (Ultra-3)
-
A parallel SCSI interface standard generation used for block-level data transfers with specified signaling and bus management.
-
SCSI (Async)
-
The asynchronous mode of SCSI protocol using request/acknowledge handshakes instead of a shared clock for data transfer.
-
Data Transfer
-
The process of moving data between storage devices and hosts, often measured in units relevant to the interface protocol.
