Examples
-
2 SCSI (Ultra-3) converts to approximately 405.58 Virtual Tributary 6 (signal)
-
0.5 SCSI (Ultra-3) converts to approximately 101.39 Virtual Tributary 6 (signal)
Common Use Cases
-
Connecting legacy enterprise hard drives and RAID controllers using SCSI (Ultra-3)
-
Mapping T1/DS1 and similar PDH/TDM circuits onto SONET networks via VT6 channels
-
Designing and diagnosing storage subsystems for throughput benchmarking
-
Traffic grooming and bandwidth allocation in optical SONET/SDH multiplexers
-
Transporting legacy subrate signals across optical transport frameworks
Tips & Best Practices
-
Double-check input values for accuracy before conversion
-
Use this tool for theoretical bandwidth estimation rather than physical layer measurements
-
Consider protocol and signaling differences during integration planning
-
Apply conversions primarily for compatibility and capacity analysis between storage and network systems
Limitations
-
Conversion reflects theoretical bandwidth and may not capture actual throughput effects
-
Does not account for signal framing and protocol overhead differences
-
SCSI (Ultra-3) and Virtual Tributary 6 operate on different physical layers and protocols
-
Direct physical interoperability is not possible; this tool is for traffic engineering purposes
Frequently Asked Questions
-
What does SCSI (Ultra-3) refer to?
-
SCSI (Ultra-3) is a parallel storage interface standard used for block-level data transfers between hosts and storage devices, specifically a revision within the parallel SCSI family.
-
What is Virtual Tributary 6 (VT6)?
-
Virtual Tributary 6 is a logical sub-channel within the SONET family used to multiplex lower-rate client signals inside an STS-1 payload for transport over optical networks.
-
Can I use this conversion for direct physical connections?
-
No, this conversion applies to theoretical bandwidth and traffic engineering; SCSI (Ultra-3) and VT6 operate on different protocols and physical layers.
