SCSI and iSCSI

SCSI (Small Computer System Interface)

• Purpose: A technique for interfacing a computer to high-speed devices such as hard disk drives, tape drives, CDs, and DVDs
• Design: Supports devices of a more permanent nature
• Type: A systems interface
• Requirements: Requires a SCSI adapter

Use Cases:

• Enterprise Storage: Used in environments requiring high-speed data transfer and reliability, such as data centers and server rooms.
• High-Performance Computing: Suitable for applications needing fast access to storage devices.

iSCSI (Internet SCSI)

• Purpose: A technique for interfacing disk storage to a computer via the Internet
• Design: Extends SCSI functionality over IP networks

Use Cases:

• Storage Area Networks (SANs): Utilized in SANs for remote storage access over existing network infrastructure.
• Cost-Effective Storage Solutions: Provides a way to use existing network infrastructure for storage access, reducing costs.
