Product Description
The Dell 02H794 is a PERC 3 (PowerEdge RAID Controller) card designed for use in older Dell PowerEdge server systems. It utilizes a U160 SCSI interface, which was a common high-performance interface for storage in servers of its era. The 'single channel' designation indicates its connection capabilities, and the PCI form factor means it is designed to be installed in a PCI expansion slot on the server's motherboard. This controller card provides hardware-level RAID capabilities, meaning it offloads the processing of RAID calculations from the server's main CPU. It supports standard RAID levels such as RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), RAID 5 (striping with parity for a balance of performance and redundancy), and RAID 10 (striped sets of mirrored pairs for both performance and redundancy). This allows for improved data availability and potentially faster data access compared to software RAID solutions. The PERC 3 U160 controller is suitable for environments that still rely on SCSI-based storage and require basic RAID functionality for data protection and performance enhancement. Its primary use case is in legacy Dell server infrastructure where upgrades to newer interfaces like SAS or SATA are not feasible or desired. It represents a foundational level of RAID control for ensuring data integrity in critical server applications.
