Limitations
-
Conversion assumes steady signal rates and does not include any protocol overhead
-
Physical layer or signaling differences may limit direct interoperability despite matched data rates
-
Effective conversion requires suitable devices or gateways bridging SCSI and VT2 formats
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 data-transfer performance and longer cable lengths.
-
What is Virtual Tributary 2 (VT2)?
-
Virtual Tributary 2 is a SONET/SDH sub-rate signal format carrying a 2.048 Mbps payload, used to multiplex lower-rate PDH circuits into higher-rate containers.
-
Why convert from SCSI (Ultra-2) to VT2 signals?
-
Conversion allows translation of block-storage device data rates into telecom signal rates, supporting integration of data center storage with SONET/SDH telecommunications infrastructure.
