Suitable for enterprise storage and telecommunications network integration
Examples
-
2 SCSI (Ultra-2) equals 740.7407407408 Virtual Tributary 1 (signal)
-
0.5 SCSI (Ultra-2) equals 185.1851851852 Virtual Tributary 1 (signal)
Common Use Cases
-
Connecting enterprise disk arrays and RAID controllers to servers using block storage interfaces
-
Attaching backup drives and removable-media libraries in data centers
-
Interfacing legacy high-performance workstations with parallel SCSI devices
-
Carrying lower-rate circuits like DS1/T1 or E1 over SONET/SDH networks
-
Grooming and aggregating multiple sub-rate services into high-rate SONET trunks
-
Independently managing individual sub-rate channels within SONET/SDH systems
Tips & Best Practices
-
Ensure compatibility of devices before applying conversions for integration
-
Use the conversion results as a reference point for network design and planning
-
Consider additional encapsulation or hardware needed when interfacing block storage with telecom signals
-
Be aware of overhead and protocol differences that might affect real-world performance
Limitations
-
Conversion is based on ideal scenarios and ignores protocol overheads or efficiency variations
-
Does not account for practical bandwidth constraints of different hardware
-
Mapping from block storage interfaces to telecom frames might require extra conversion equipment
Frequently Asked Questions
-
What does SCSI (Ultra-2) represent?
-
SCSI (Ultra-2) is a parallel Small Computer System Interface standard that uses Low Voltage Differential signaling for higher performance and longer cable lengths, commonly used for block storage devices.
-
What is a Virtual Tributary 1 (signal)?
-
Virtual Tributary 1 is a logical sub-channel in SONET/SDH networks that encapsulates lower-rate plesiochronous digital signals within higher-rate synchronous transport frames.
-
Why convert SCSI (Ultra-2) to Virtual Tributary 1 (signal)?
-
Users convert these units to translate storage interface data rates into logical sub-channel streams suitable for SONET/SDH transport, enabling integration between storage and telecommunications infrastructure.
-
Does this conversion reflect real-world performance?
-
No, the conversion assumes ideal conditions and does not consider overhead, protocol efficiency, or equipment bandwidth limitations.
