LSI Pseudo Device Windows Driver

The LSI Pseudo Device Driver refers to a software driver used in systems with LSI (now part of Broadcom) storage controllers. These drivers typically help the operating system communicate with virtual or "pseudo" devices created by the controller, such as virtual disks or RAID arrays. The term "pseudo device" generally refers to a logical or virtual device that doesn't correspond to a physical piece of hardware but is managed through software.

LSI storage controllers, such as those in the LSI MegaRAID or SAS controller families, often use pseudo devices to allow the operating system to interface with complex RAID configurations or virtual storage devices. The "pseudo device" driver facilitates communication between the RAID controller and the operating system to access data on these virtualized devices, often providing features like RAID management, health monitoring, and configuration.
