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. #OPENZFS DRAID SOFTWARE#This isn’t the case in software RAID where the software uses the common resources of the system including any other applications or services. 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. There’s several issues that contribute to people opting for software RAID instead of hardware RAID like the fact that it requires proprietary software. It’s typically configured via the BIOS or some other system prior to the launch of the OS. 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. Hardware RAID: Vendors, Controllers et al. This multitude of setups and configurations is one of the reasons that RAID has become as popular as it is today. 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). Software RAID can be configured and used in many different ways. The second type is “ software RAID ” where the RAID support consists of software running on the server. This is the kind of RAID you can find recommended for one of our earlier products, Open-E DSS V7, albeit that product also supported software RAID. The first type is “hardware RAID” where the RAID engine is actually built into the server hardware. The first thing you, our intrepid reader, should know is that there are two main types of RAID (along with a plethora of customizable options). So what is a Redundant Array of Independent Disks and how do we use it in the development world? The Softer Side of RAID It’s also an excellent way to show how the word evolved from one that inspired terror and chaos to one that now signifies security and protection from what, for a lot of people, would certainly be terror and chaos. So, why is there a picture of a Viking on our technology blog, some of our more intrepid readers might be thinking? Well, the answer is simple enough, it’s because today we talk about raiding… or rather, RAID, which admittedly might not be as exciting to some as raiding but is fundamental to the way data storage functions nonetheless. #OPENZFS DRAID FULL#Vikings wore full armor just like everyone else in that time period.
