Metadata Support The Integrated RAID firmware supports metadata, which describes the RAID volume configuration stored on each member disk of a volume. After initialization, the firmware reads the metadata on each member disk and verifies the configuration. The firmware reduces the usable disk space for each member disk when it creates the volume to make room for the metadata. SMART Support The Self-Monitoring Analysis and Reporting Technology (SMART) monitors disk drives for signs of possible future disk failure and generates an alert if it detects such signs. The Integrated RAID firmware polls each physical disk in the volume at regular intervals. If the firmware detects a SMART ASC/ASCQ code on a physical disk in the volume, it stores the SMART data in a log. Fusion-MPT Support The Integrated RAID BIOS uses the Intel Fusion-MPT interface to communicate to the SAS-3 controller and firmware. This process includes reading the Fusion-MPT configuration to access the parameters that define behavior between the SAS-3 controller and the devices that connect to it. The Fusion-MPT drivers for all supported operating systems implement the Fusion-MPT interface to communicate with the controller and firmware. CacheCade on Host The Integrated RAID solution is fully compatible with the Intel CacheCade™ on Host (CCoH) software solution. CCOH accelerates the I/O speed of high-performance applications that would otherwise be constrained by HDD performance. For more information about CCoH, refer to the Intel CacheCade on Host User Guide. Intel® Integrated RAID Solution User Guide 3

Metadata Support

The Integrated RAID firmware supports metadata, which describes the RAID volume

configuration stored on each member disk of a volume. After initialization, the firmware

reads the metadata on each member disk and verifies the configuration. The firmware

reduces the usable disk space for each member disk when it creates the volume to make

room for the metadata.

SMART Support

The Self-Monitoring Analysis and Reporting Technology (SMART) monitors disk drives

for signs of possible future disk failure and generates an alert if it detects such signs. The

Integrated RAID firmware polls each physical disk in the volume at regular intervals. If

the firmware detects a SMART ASC/ASCQ code on a physical disk in the volume, it

stores the SMART data in a log.

Fusion-MPT Support

The Integrated RAID BIOS uses the Intel Fusion-MPT interface to communicate to the

SAS-3 controller and firmware. This process includes reading the Fusion-MPT

configuration to access the parameters that define behavior between the SAS-3 controller

and the devices that connect to it. The Fusion-MPT drivers for all supported operating

systems implement the Fusion-MPT interface to communicate with the controller and

firmware.

CacheCade on Host

The Integrated RAID solution is fully compatible with the Intel CacheCade

™

on Host

(CCoH) software solution. CCOH accelerates the I/O speed of high-performance

applications that would otherwise be constrained by HDD performance.

For more information about CCoH, refer to the
