Product Description
The Dell 0NDD93 is a Dell PowerEdge RAID Controller (PERC) card, likely a PERC H700 or similar model, designed to provide robust hardware RAID capabilities for Dell servers. It supports SAS and SATA drives operating at 6Gbps, offering a significant performance upgrade over older SATA 3Gbps interfaces. The card is equipped with 1GB of cache memory, which serves as a high-speed buffer to accelerate disk operations, particularly write-intensive tasks, and improves overall storage subsystem performance by reducing latency and increasing throughput. This dedicated cache memory, combined with the controller's own processor, ensures efficient RAID management without burdening the server's main CPU. Utilizing the PCI Express 2.0 x8 interface, the 0NDD93 provides substantial bandwidth, crucial for handling the demands of multiple high-speed drives in a RAID array. This interface ensures that the controller can keep pace with the data flow from SAS 6Gbps drives. The controller supports a wide range of hardware RAID levels, including RAID 0 (striping for performance), RAID 1 (mirroring for redundancy), RAID 5 (striping with parity for balance), RAID 6 (striping with dual parity for enhanced redundancy), and RAID 10 (striped mirrors for performance and redundancy), as well as RAID 50 and 60 for larger arrays. This flexibility allows administrators to configure storage solutions tailored to specific application requirements, whether prioritizing speed, data protection, or capacity. This PERC controller is designed for internal drive connections within Dell servers, typically using SFF-8087 connectors to link to the server's drive backplane. Its hardware RAID implementation provides superior performance and data protection compared to software RAID solutions. The Dell 0NDD93 is a reliable component for building fault-tolerant storage systems, ensuring data availability and integrity in mission-critical applications. Management is typically handled through Dell's OpenManage software or the server's integrated BIOS/UEFI configuration utilities.
