What does SCSI (Ultra-3) represent?

SCSI (Ultra-3) is a version of the Small Computer System Interface parallel storage interface standard used for block-level data transfers between hosts and storage devices.

What is STM-4 (signal) used for?

STM-4 (signal) is an optical transport frame in the Synchronous Digital Hierarchy used for multiplexing and transporting digital traffic in telecom carrier networks.

Can SCSI (Ultra-3) data be directly transferred over STM-4 networks?

No, SCSI (Ultra-3) and STM-4 operate in different domains; direct data exchange is not typical, the conversion is mainly for rate comparison and interoperability planning.
