HighPoint RAID Classes: Data RAID vs. Boot RAID

HighPoint uses the terms “Data RAID” and Boot-RAID” to describe the primary function of a RAID array.

Data-RAID: Storage Volumes

Data RAID: a RAID array that is only used to store or process data. An operating system will recognize a Data-RAID array as a single physical drive, which can then be formatted/partitioned as needed.

In most cases, Data-RAID arrays can be easily moved from one system or another, provided it is connected to a compatible HighPoint product (such as moving a RAID 0 array between two SSD7000 series controllers).

Boot-RAID: Bootable Volumes

Boot-RAID: a RAID array that functions as a system disk (bootable drive or volume). In most cases, a Boot-RAID is configured as a redundant RAID array (RAID 1, 5, 6, 10, etc.), as it adds a layer of data security to the OS.

Boot-RAID volumes must be created before an OS can be installed; a bootable drive cannot be converted into a RAID array. Depending on the product in use, administrators can configure the array using the controller’s BIOS interface or EUFI tool.

Note: Though a Boot-RAID array can be moved from one HighPoint solution to another within the same product class, and remain recognized, the Boot-RAID is unlikely to remain bootable. This isn’t unique to HighPoint or RAID in general. Boot-volumes (this includes bootable, single disks) are generally “tied” to the computing platform that was in place at the time of the original OS installation. The Boot-RAID volume would be recognized and readable, but could not be used to boot another system.
