What Is This Tool?
This tool helps convert data transfer rates from the synchronous SCSI standard known as SCSI (Sync) to the parallel interface standard, SCSI (Ultra-3). It allows users to compare performance and compatibility across different generations of storage interfaces.
How to Use This Tool?
-
Enter the value in SCSI (Sync) units you wish to convert.
-
Select the target unit as SCSI (Ultra-3).
-
Click convert to see the equivalent data transfer rate in SCSI (Ultra-3).
Key Features
-
Converts data transfer rates between SCSI (Sync) and SCSI (Ultra-3) units.
-
Based on a fixed conversion ratio specific to parallel SCSI interfaces.
-
Supports comparisons for enterprise storage devices and backup systems.
Examples
-
Convert 10 SCSI (Sync) to SCSI (Ultra-3): 10 × 0.03125 = 0.3125 SCSI (Ultra-3).
-
Convert 32 SCSI (Sync) to SCSI (Ultra-3): 32 × 0.03125 = 1 SCSI (Ultra-3).
Common Use Cases
-
Comparing and translating transfer speeds between legacy synchronous SCSI and Ultra-3 devices.
-
Configuring RAID controllers and storage arrays that use mixed SCSI technologies.
-
Benchmarking parallel SCSI interface compatibility in storage subsystem design and diagnostics.
Tips & Best Practices
-
Always verify unit definitions when converting between storage interface standards.
-
Consider device-specific behaviors since actual throughput can differ from nominal conversion rates.
-
Use this conversion primarily for parallel SCSI interfaces and synchronous transfer modes.
Limitations
-
Conversion ratio does not include protocol overhead, device-specific delays, or implementation variations.
-
Not applicable for serial SCSI versions or newer storage interface technologies.
-
Only useful for parallel SCSI synchronous speeds as defined by the standards.
Frequently Asked Questions
-
What does SCSI (Sync) represent?
-
SCSI (Sync) denotes the synchronous transfer mode of the SCSI protocol with data transfers synchronized to a negotiated clock, allowing higher throughput and consistent timing.
-
What is SCSI (Ultra-3)?
-
SCSI (Ultra-3) is a parallel SCSI standard revision used for block-level data transfers, commonly found in enterprise storage devices and backup systems.
-
Can I use this conversion for serial SCSI devices?
-
No, this conversion only applies to parallel SCSI interfaces and their synchronous transfer modes, not to serial or newer SCSI variants.
Key Terminology
-
SCSI (Sync)
-
A synchronous mode of the SCSI protocol where data transfers occur in lockstep with a negotiated clock, enabling high throughput and consistent timing.
-
SCSI (Ultra-3)
-
A parallel SCSI interface standard defining signaling and data transfer characteristics, used in enterprise storage and backup devices.
-
Parallel SCSI
-
A class of SCSI interfaces using parallel signal transmission, differing from serial variants.
