Which technology is used mainly in enterprise environments for connecting storage devices to servers and workstations?

The technology primarily utilized in enterprise environments for connecting storage devices to servers and workstations is Serial Attached SCSI (SAS). This interface provides high data transfer rates, robust reliability, and enhanced performance for enterprise-level storage solutions. SAS is designed to support large numbers of devices on a storage network, enabling the connection of up to 65,535 devices through expanders.

SAS is particularly beneficial in environments that require constant data access and throughput, such as data centers and high-performance computing applications. This technology also supports advanced features like dual porting, which allows for redundancy and increased availability, making it well-suited for critical enterprise applications.

In contrast, USB, while widely used for peripheral connections, does not offer the performance or scalability needed in enterprise storage environments. FireWire (IEEE 1394) is also more suited for consumer and professional audio/video devices rather than enterprise storage applications. On the other hand, PATA (Parallel ATA) is an older technology that has largely been phased out in favor of SATA and SAS due to its limitations in speed and scalability.
