What Is This Tool?
This converter translates data transfer rates from the legacy SCSI (Fast) standard to the STS3c (payload) unit used in SONET optical transport networks. It helps bridge legacy storage interface speeds with modern high-bandwidth optical network capacities.
How to Use This Tool?
-
Enter the value in SCSI (Fast) that you want to convert.
-
Select SCSI (Fast) as the input unit and STS3c (payload) as the output unit.
-
Click the convert button to see the equivalent data transfer rate in STS3c (payload).
Key Features
-
Converts data transfer units from SCSI (Fast) to STS3c (payload).
-
Supports translating legacy parallel SCSI throughput into SONET payload rates.
-
Provides an easy multiplier conversion based on nominal throughput values.
-
Ideal for telecommunications and data center network planning.
-
Browser-based and straightforward to use without installation.
Examples
-
Converting 2 SCSI (Fast) results in approximately 1.0643 STS3c (payload).
-
Converting 5 SCSI (Fast) gives around 2.6607 STS3c (payload).
Common Use Cases
-
Mapping legacy SCSI data transfer speeds to SONET optical transport payloads for network design.
-
Planning backbone optical links carrying Ethernet or IP circuits.
-
Facilitating leased-line service capacity allocation around 155 Mbps for enterprises.
-
Managing data center migrations from parallel SCSI storage to modern optical networks.
-
Linking storage devices within legacy RAID or disk-array systems to newer optical carrier infrastructure.
Tips & Best Practices
-
Verify the conversion fits your network's specific protocol overhead and efficiency needs.
-
Use the converter as a guideline for nominal throughput, and consider real-world variations.
-
Apply this conversion when designing hybrid environments involving legacy and modern technologies.
-
Consult actual device and network documentation for precise bandwidth management.
Limitations
-
Conversion reflects nominal throughput values and does not account for transfer overhead.
-
Legacy SCSI systems have scalability constraints compared to modern optical transport solutions.
-
SONET payload overhead slightly reduces the effective data rate below the gross rate.
Frequently Asked Questions
-
What does SCSI (Fast) represent?
-
SCSI (Fast) is a parallel SCSI extension increasing transfer rates to about 10 MB/s in legacy storage systems using faster timing and signaling.
-
What is STS3c (payload) used for?
-
STS3c (payload) is a SONET transport channel with a gross line rate of 155.52 Mbps, carrying high-bandwidth client signals across optical networks.
-
Why convert between SCSI (Fast) and STS3c (payload)?
-
Converting helps translate legacy storage data throughput into modern optical transport capacities for network planning and integration.
Key Terminology
-
SCSI (Fast)
-
A legacy parallel SCSI extension that increases data transfer speeds by using faster timing, often reaching about 10 MB/s.
-
STS3c (payload)
-
A concatenated SONET Transport Signal level-3 payload channel used to carry client signals at a gross rate of 155.52 Mbps.
-
SONET
-
Synchronous Optical Network, a standardized protocol that transports multiple digital bit streams over optical fiber.
