iSCSI Storage Systems for Multiple Servers

D.

The correct answer is D. SAN.

A Storage Area Network (SAN) is a high-speed network that provides block-level access to data storage. It is designed to provide shared access to storage devices such as disk arrays, tape libraries, and optical jukeboxes. A SAN is typically composed of a fabric of interconnected switches and storage devices that allow multiple servers to access the same storage devices at the same time.

iSCSI is a protocol used to send SCSI commands over a network. This allows a server to access storage devices over an Ethernet network rather than requiring a direct connection. iSCSI can be used to connect servers to storage devices on a SAN.

JBOD (Just a Bunch Of Disks) is a storage system that connects a number of disks together without providing any RAID functionality. It is typically used for low-cost storage solutions where redundancy and high availability are not a concern.

DAS (Direct Attached Storage) is a storage system that is directly connected to a server or workstation. This type of storage is typically used in small-scale environments where the number of servers is limited.

NAS (Network Attached Storage) is a storage system that provides file-level access to data storage. It is typically used in small-scale environments where file sharing is required.

In summary, a SAN is a storage system that can be connected to multiple servers through an iSCSI connection. It provides block-level access to data storage and is designed for high availability and performance.
