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.”
