What Is This Tool?
This tool converts data transfer rates from SCSI (Ultra-3), a parallel storage interface standard, to Virtual Tributary 2 (payload), a SONET/SDH virtual container used for transmitting PDH/E1 channels over optical networks. It supports professionals integrating storage subsystems with synchronous optical transport networks.
How to Use This Tool?
-
Enter the numerical value you want to convert from SCSI (Ultra-3).
-
Select SCSI (Ultra-3) as the input unit and Virtual Tributary 2 (payload) as the output unit.
-
Click on convert to see the equivalent data transfer rate in Virtual Tributary 2 (payload).
-
Use the result to assist in data center backup planning or optical network provisioning.
Key Features
-
Converts between SCSI (Ultra-3) and Virtual Tributary 2 (payload) data units.
-
Browser-based and easy to use for quick data rate translations.
-
Supports legacy system integration and migration scenarios.
-
Shows precise conversion based on a fixed conversion rate.
Examples
-
2 SCSI (Ultra-3) equals 1250 Virtual Tributary 2 (payload).
-
0.5 SCSI (Ultra-3) converts to 312.5 Virtual Tributary 2 (payload).
Common Use Cases
-
Connecting enterprise hard drives and RAID controllers in legacy storage arrays.
-
Mapping data rates for tape drives and backup libraries in data centers.
-
Transporting legacy TDM signals over SONET/SDH optical backbones.
-
Benchmarking and designing storage subsystem compatibility with optical networks.
Tips & Best Practices
-
Ensure understanding of both SCSI and SONET/SDH data transfer concepts before conversion.
-
Use the tool to facilitate migration from parallel storage protocols to optical transport frameworks.
-
Verify synchronization and signaling compatibility separately as this conversion covers data rate mapping only.
-
Consult with networking professionals for integration requiring protocol encapsulation beyond basic unit conversion.
Limitations
-
Conversion presumes compatible data transfer and synchronization mechanisms between the units.
-
Does not address physical layer or signaling differences between parallel SCSI and synchronous optical multiplexing.
-
Additional protocol conversion might be necessary for practical interoperability.
-
Applicable specifically to data rate translation; not a substitute for detailed protocol bridging.
Frequently Asked Questions
-
What does SCSI (Ultra-3) refer to?
-
SCSI (Ultra-3) is a version of the Small Computer System Interface standard defining parallel block-level data transfers between hosts and storage devices.
-
What is Virtual Tributary 2 (payload)?
-
Virtual Tributary 2 (VT2) is a SONET/SDH container designed to carry 2.048 Mb/s PDH/E1 channels for transporting lower-rate TDM signals over optical networks.
-
Why convert SCSI (Ultra-3) units to Virtual Tributary 2 (payload)?
-
This conversion helps translate legacy storage interface data rates into optical network units, supporting integration and migration between storage and synchronous optical transport environments.
