9.0 SOFTWARE RAID It is possible to use software RAID for striping or mirroring multiple X8 Accelerator devices. Note that X8 Accelerator devices have embedded flash-aware RAID with 7+1P redundancy that provides protection against bad blocks and flash component failures. This reduces the need for mirroring X8 Accelerator devices in some usage scenarios. The default software RAID creation parameters are sufficient for good read and write performance. Below is an example of creating a striped volume across two X8 Accelerator devices: #mdadm --create /dev/md0 --level=0 --raid-devices=2 /dev/vgca0 /dev/vgca1 10.0 MANAGEMENT UTILITIES 10.1 vgc-monitor vgc-monitor utility allows monitoring of X8 Accelerator device status and health.
