The SKU:3KDWX refers to a specific Dell product part number. It is a Dell PERC H755 Modular 12G SAS Front RAID Controller. They are high-performance RAID controllers designed for Dell PowerEdge 15th Generation servers, offering features like 12Gb/s SAS and 6Gb/s SATA support and 8GB of cache memory
They are used in enterprise server environments to manage and protect data by creating redundant storage arrays (RAID). The large cache memory helps improve data access and overall server performance.
Alternate or equivalent part numbers you may encounter for this same component include 03KDWX and P4X7G.
An actual controller is located inside Dell PowerEdge servers, specifically designed to fit into a dedicated "front PERC module" slot.
It's not a standard PCIe card that you would plug into a generic slot.
This modular design is common in modern Dell servers and allows the RAID controller to connect directly to the drive backplane. It's typically positioned at the front of the server, near the drive bays, to facilitate a clean, cabled connection to the drives. This location is key for managing the SAS and SATA drives that are hot-swapped from the front of the server chassis.
To access the controller, you must first power down the server, disconnect all cables, and remove the chassis cover. The controller is then found inside the chassis and is often secured by a few screws or clips.
