Adaptec AIC-7902 HostRAID driver

Windows device driver information for Adaptec AIC-7902 HostRAID driver

The Adaptec AIC-7902 HostRAID is a proprietary technology that is implemented to reference RAID technology integration to provide an entry level support for the storage media strategy. This particular technology supported by the accompanying device driver is also often referred to as software RAID or intelligent RAID on chip. Presumably this is because the firmware is already embedded into the controller of the supported hardware component thereby eliminating the need for the activation of additional processors. The HostRAID card controllers are therefore by default enabled in the host computer system. Provided however that the correct device driver has been installed in order to correctly identify the presence of the supported hardware component. According to some computer experts the device driver for the Adaptec AIC-7902 HostRAID and similar hardware components can support both JBOD and RAID mode. The required driver files however would depend on the setting of the HostRAID component.

The term HostRAID is considered a proprietary technology because it specifically references an Adaptec based support device. This hardware component like the Adaptec AIC-7902 HostRAID is responsible for the implementation of RAID functionality in the host computer system. What this means is that the deployment of this particular hardware component and its corresponding device driver is equivalent to that of other computer systems which make use of RAID compliant devices that are not manufactured by Adaptec. The HostRAID technology supported by the device driver of this particular hardware component is commonly embedded into the newer Ultra320 SCSI Host controller chipsets. The result of the deployment of this technology is that once HostRAID is enabled in the BIOS the host controller will switch its operational mode and will be immediately recognized by the underlying operating system environment as a completely different controller architecture.
