Product Description
The Dell UN939 is a dedicated RAID controller designed to enhance storage capabilities within Dell server environments. Featuring a PCI Express x4 interface, it offers ample bandwidth to support multiple SAS (Serial Attached SCSI) drives operating at 3Gb/s per lane. This controller is crucial for implementing advanced storage configurations that improve data reliability, performance, or both, through hardware-based RAID (Redundant Array of Independent Disks). This controller supports essential RAID levels, including RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), RAID 5 (striping with parity for balanced performance and redundancy), and RAID 10 (a combination of striping and mirroring for high performance and redundancy). By offloading RAID calculations from the host CPU to its dedicated processor, the UN939 ensures efficient operation and minimizes performance impact on the server's main processing tasks. Designed specifically for integration into Dell servers, the UN939 provides a robust solution for managing SAS storage arrays. It allows IT administrators to configure and protect their data effectively, ensuring business continuity through redundancy and optimizing storage performance for demanding applications. Its PCIe x4 interface ensures it can be installed in a wide range of compatible Dell server models.
