Which of the following uses IP networks that enable servers to access remote disks as if they were locally attached?

SAS
SATA
iSCSI
Fibre Channel

The correct answer is: iSCSI

The correct answer is iSCSI. This technology is specifically designed to enable SCSI commands to be sent over IP networks, allowing servers to communicate with and access remote storage devices as if they were physically attached to the server. This capability is crucial for creating storage area networks (SANs), where storage resources are centralized and can be accessed by multiple servers. iSCSI operates over standard Ethernet networks, making it a cost-effective solution for leveraging existing networking infrastructure. It achieves this by encapsulating SCSI commands into IP packets, thus allowing a seamless integration of local and remote storage systems. On the other hand, SAS (Serial Attached SCSI) and SATA (Serial ATA) are storage technologies that typically refer to local storage connectivity methods. They do not have the capability to access remote disks over IP networks. Fibre Channel is another high-speed networking technology specifically designed for storage networking, but it operates on its own infrastructure and does not use IP networks in the same way that iSCSI does. This distinction is essential for understanding how storage solutions can be implemented in various networking environments.
