What Is This Tool?
This converter transforms data transfer rates expressed in SCSI (Sync) units into equivalent rates measured in STS1 (signal) units. It facilitates the comparison and integration of storage interface speeds used in servers and RAID arrays with telecom network transport rates based on SONET technology.
How to Use This Tool?
-
Enter the value of data transfer rate in SCSI (Sync) units
-
Select SCSI (Sync) as the source unit and STS1 (signal) as the target unit
-
Click the convert button to obtain the equivalent data rate in STS1 (signal)
-
Use the result for planning network and storage system integrations
Key Features
-
Converts data transfer rates from SCSI synchronous mode to STS1 signal rates
-
Supports standard usage scenarios in IT storage and telecom networks
-
Provides clear mapping for system integration between storage devices and SONET transport
-
Easy-to-use, browser-based interface for quick calculations
Examples
-
Convert 5 SCSI (Sync) units: 5 × 0.7716049383 = 3.8580246915 STS1 (signal)
-
Convert 10 SCSI (Sync) units: 10 × 0.7716049383 = 7.716049383 STS1 (signal)
Common Use Cases
-
Translating data rates from SCSI storage interfaces to SONET telecommunications networks
-
Supporting data center infrastructure where storage arrays use SCSI synchronous transfers while network backbones use STS1 signals
-
Configuring leased line or point-to-point circuits over fiber with SONET framing aligned to storage data rates
Tips & Best Practices
-
Verify the negotiated SCSI synchronous transfer parameters for accurate conversion
-
Consider network and device configurations that may affect actual throughput
-
Use the converter as a planning tool rather than a precise measurement due to protocol overhead differences
Limitations
-
Does not cover protocol overhead or error correction differences between SCSI and SONET
-
Actual throughput may deviate due to network conditions and hardware setup
-
STS1 values include SONET overhead; net payload rates are different from gross line rates
Frequently Asked Questions
-
What does SCSI (Sync) represent in data transfer?
-
SCSI (Sync) denotes the synchronous transfer mode of the SCSI protocol where data is transferred synchronized to a negotiated clock between initiator and target for higher throughput and deterministic timing.
-
What is STS1 (signal) in telecommunications?
-
STS1 (signal) is the basic SONET electrical unit operating at 51.84 megabits per second, framing data every 125 microseconds and serving as the fundamental transport container in synchronous optical networking.
-
Why convert between SCSI (Sync) and STS1 (signal)?
-
Converting helps translate storage interface speeds to telecom network rates, enabling system integration where SCSI devices communicate over SONET networks using STS1 framing.
Key Terminology
-
SCSI (Sync)
-
A synchronous data transfer mode in the SCSI protocol enabling data transfer in lockstep with a negotiated clock for consistent and higher throughput.
-
STS1 (signal)
-
The basic unit of SONET synchronous transport carrying a line rate of 51.84 Mbps, framing data every 125 microseconds, equivalent to an OC-1 optical carrier.
-
SONET
-
Synchronous Optical Network, a standardized protocol for transferring multiple digital bit streams over optical fiber using synchronous framing.
