Product Description
The Dell 81UEM, also known as PERC2, is a robust SCSI RAID controller card that enhances storage capabilities within Dell PowerEdge servers. It is equipped with four SCSI ports, allowing for the connection of multiple hard drives or other SCSI storage peripherals. This controller is crucial for environments that rely on SCSI-based storage, offering a reliable way to manage and protect data. By implementing hardware RAID, the 81UEM offloads the processing of RAID calculations from the server's CPU, leading to significant improvements in input/output (I/O) performance. This is particularly beneficial for database applications, file servers, and other I/O-intensive workloads. The card supports various RAID levels, enabling administrators to configure storage arrays for optimal balance between performance, redundancy, and capacity. Compatibility is primarily with older generations of Dell PowerEdge servers that utilize PCI 64-bit slots and require SCSI storage. The 81UEM is a valuable component for maintaining or upgrading storage infrastructure in environments where SCSI technology is still prevalent, ensuring data safety through redundant configurations and boosting overall system responsiveness.
