Question

Which drive interconnect technology uses SCSI commands and a serial bus?

Options

ASAS
BiSCSI
CSDI
DSATA

Explanation

SAS (Serial Attached SCSI) is the correct answer. It combines two defining characteristics: it transmits data over a high-speed serial bus (replacing the older parallel SCSI bus), and it uses the SCSI command set for communication with storage devices. This makes SAS backward-compatible with SCSI semantics while delivering faster speeds and better scalability. iSCSI (B) also uses SCSI commands but encapsulates them over a TCP/IP Ethernet network - not a serial bus in the drive-interconnect sense. SATA (D) uses a serial bus but uses ATA commands, not SCSI commands, making it a distinct protocol family. SDI (C) is not a recognized standard drive interconnect technology and is a distractor.
