E2K-UCS-50 Dell Perc 5/e Dual Channel 8port (PCI-E) Serial-Attached SCSI (SAS) Controller

SAS, which stands for Serial Attached SCSI, is a technology that is commonly used for connecting hard drives and other storage devices to a computer or server. A SAS controller, also known as a SAS HBA (Host Bus Adapter), is a crucial component that manages the flow of data between the computer’s motherboard and the storage devices.

SAS controllers are designed to handle high-speed data transfers and are often used in enterprise-level environments where data integrity and performance are of utmost importance. These controllers come in various forms, including internal and external, and offer different numbers of ports to connect multiple storage devices.
