The second type is “ software RAID ” where the RAID support consists of software running on the server. ![]() Software RAID can be configured and used in many different ways. For instance, it can be configured to abstract many disks into one virtual device like in OpenBSD’s softraid, act as a more generic file manager like in LVM, or become a component of the file system like in BTRFS or ZFS (which is actually how Open-E JovianDSS uses it). This multitude of setups and configurations is one of the reasons that RAID has become as popular as it is today. Hardware RAID: Vendors, Controllers et al. So what is hardware RAID? Well, like it’s name implies, hardware RAID consists of a RAID controller, a piece of hardware that acts as a go-between for the operating system and physical disks, that is actually added to the system in question. It’s typically configured via the BIOS or some other system prior to the launch of the OS. There’s several issues that contribute to people opting for software RAID instead of hardware RAID like the fact that it requires proprietary software. This, in turn, creates a vendor lock-in where the customer is stuck to the hardware RAID vendor that they purchased the hardware RAID from if they want to continue to use said hardware. This isn’t the case in software RAID where the software uses the common resources of the system including any other applications or services. AN INTERNAL PART OF THE SOFTRAID APPLICATION SOFTWARE While this can be good or bad, it does give users a level of flexibility that the vendor lock-in of hardware RAID can’t match. It starts at 0 and goes upwards to 6 in terms of the most popular ones but there’s also ways to hybridize it or embed it (nested RAID) which creates concepts like RAID 10 or RAID 100 amongst others. ![]() Given that discussing the differences between all of the various ways to hybridize RAID could easily form several articles, it’s not something that will be discussed here. ![]() AN INTERNAL PART OF THE SOFTRAID APPLICATION SOFTWARE.AN INTERNAL PART OF THE SOFTRAID APPLICATION FULL.
