What Is This Tool?
This tool converts data transfer rates between STS3c (payload), used in optical transport networks, and SCSI (Fast Ultra), a high-speed storage interface. It helps relate backbone network bandwidth to storage device throughput.
How to Use This Tool?
-
Enter the value in STS3c (payload) units you want to convert
-
Select SCSI (Fast Ultra) as the target unit
-
View the converted result instantly
Key Features
-
Converts STS3c (payload) data rates to SCSI (Fast Ultra) speeds
-
Supports understanding optical network and storage interface bandwidth equivalence
-
Browser-based and easy to use without additional software
-
Includes relevant examples for quick reference
Examples
-
1 STS3c (payload) is equal to 0.9396 SCSI (Fast Ultra)
-
10 STS3c (payload) converts to 9.396 SCSI (Fast Ultra)
Common Use Cases
-
Backbone optical links (OC-3) carrying Ethernet or IP circuits between nodes
-
Designing leased-line services with approximately 155 Mbps circuits
-
Transporting ATM, frame relay, or client signals in SONET payload
-
Connecting high-performance hard disk arrays and RAID controllers
-
Attaching tape drives and robotic libraries for backup purposes
-
Linking legacy peripherals like optical jukeboxes and video capture devices
Tips & Best Practices
-
Use this tool to compare bandwidth across optical and storage domains effectively
-
Consider the protocol overhead differences when analyzing throughput
-
Use actual hardware specifications to validate performance beyond raw conversions
Limitations
-
Conversion rates are approximate due to framing and protocol overhead differences
-
Real throughput may vary with hardware and network conditions
-
Does not account for latency or protocol efficiency variations beyond bandwidth equivalence
Frequently Asked Questions
-
What does STS3c (payload) represent?
-
STS3c (payload) represents a contiguous transport channel in SONET with a gross rate of 155.52 Mbps, used for carrying high-bandwidth client signals over optical networks.
-
What is SCSI (Fast Ultra) used for?
-
SCSI (Fast Ultra) is a parallel signaling mode that combines Fast and Ultra extensions to increase throughput and decrease latency in storage device connections.
-
Why is the conversion approximate?
-
Because STS3c payload and SCSI signaling have different protocol overheads and framing, the conversion only indicates bandwidth equivalence and may not reflect exact throughput.
Key Terminology
-
STS3c (payload)
-
A SONET payload container offering a single contiguous transport stream at approximately 155.52 Mbps for carrying client signals.
-
SCSI (Fast Ultra)
-
A parallel SCSI signaling mode combining Fast and Ultra features to enhance data transfer rates and reduce latency in storage systems.
-
Conversion Rate
-
The factor used to translate values from STS3c (payload) units to SCSI (Fast Ultra) units, approximately 0.9396.
