iSCSI

What is iSCSI?

iSCSI (Internet Small Computer System Interface) is the network version of SCSI.

Key Points

  • Network Version of SCSI: iSCSI allows SCSI (Small Computer System Interface) to operate over a network instead of a direct physical connection.
  • Network Connection: It enables communication between computers and peripheral devices via a network, using SCSI protocols.
  • Abbreviation: iSCSI stands for “Internet Small Computer System Interface.”

Detailed Explanation

  • SCSI: SCSI is a protocol used for connecting computers and peripheral devices through physical cables.
  • Role of iSCSI: iSCSI extends the SCSI protocol to work over network connections, such as the internet or local area networks (LANs). This allows devices to communicate without requiring a physical connection.
  • Usage Difference: SCSI is used for direct cable connections, while iSCSI is used for network-based connections. Both follow the SCSI protocol but differ in how the connection is established.

In summary, iSCSI is “SCSI for networks, enabling data communication over a network instead of through direct cables.”
