A system administrator is auditing storage hardware interface standards across high-performance workstations and server systems. Match each storage interface standard on the left with its defining operational or physical characteristic on the right.

Thunderbolt 4Provides up to $40\text{ Gbps}$ bandwidth using a Type-C connector, supports daisy-chaining, and mandates PCIe data tunnelling.
U.2 (SFF-8639)A 2.5-inch form factor enterprise drive interface supporting up to four PCIe lanes, SATA, and SAS signals with hot-swap capability.
USB 3.2 Gen 2x2A dual-lane USB transfer mode achieving up to $20\text{ Gbps}$ throughput exclusively over USB Type-C physical cabling.
SAS-3An enterprise point-to-point serial storage bus delivering $12\text{ Gbps}$ per port, optimized for high-availability server backplanes.

Cevap

Thunderbolt 4 matches with

40\text{ Gbps}

bandwidth and PCIe tunnelling over Type-C; U.2 (SFF-8639) matches with 2.5-inch enterprise drive form factor with four PCIe lanes and hot-swap; USB 3.2 Gen 2x2 matches with dual-lane

20\text{ Gbps}

throughput over Type-C; SAS-3 matches with

12\text{ Gbps}

enterprise serial storage protocol.

Each storage standard is accurately paired according to its bus architecture and performance characteristics: Thunderbolt 4 requires

40\text{ Gbps}

bandwidth and PCIe tunnelling; U.2 provides four PCIe lanes in a 2.5-inch enterprise drive form factor; USB 3.2 Gen 2x2 delivers

20\text{ Gbps}

via dual-lane Type-C channels; and SAS-3 delivers

12\text{ Gbps}

serial throughput for enterprise servers.

Adım Adım Çözüm

Analyze Thunderbolt 4 parameters

Identified maximum

40\text{ Gbps}

throughput requirement, compulsory PCIe tunneling support, and daisy-chaining features using the USB Type-C physical connector.

Thunderbolt 4 standards build upon Thunderbolt 3 specifications and mandate

40\text{ Gbps}

bandwidth alongside PCIe data tunneling.

Analyze U.2 (SFF-8639) interface specifications

Mapped U.2 to the 2.5-inch form factor enterprise connector utilizing up to 4 PCIe lanes along with backward compatibility signaling.

U.2 was designed specifically to bring NVMe PCIe speeds to standard 2.5-inch hot-swappable drive bays in enterprise hardware.

Differentiate USB 3.2 Gen 2x2 performance metrics

Associated USB 3.2 Gen 2x2 with dual-lane operation achieving

20\text{ Gbps}

over USB Type-C cables.

The 'x2' designation denotes multi-lane operation utilizing two

10\text{ Gbps}

lanes available exclusively on Type-C wiring.

Identify SAS-3 enterprise bus bandwidth

Linked SAS-3 to

12\text{ Gbps}

point-to-point serial storage used in server backplanes.

SAS-3 doubles the bandwidth of SAS-2 (

6\text{ Gbps}

) to

12\text{ Gbps}

per port for enterprise storage environments.
