Consequently, you’re unlikely to use it in production environments and may opt for a fail-over backup system. That’s because you need to cater for duplicate data to make the array offer redundancy. It’s often used with relatively low cost storage hardware. This makes RAID useful for backup and NAS storage. How Do You Use RAIDĪs the name suggests, RAID is useful to set up an array that offers a redundant configuration. This is so we can make a valid comparison between both technologies. In this article, we’ll focus on the RAID 0 configuration, where you just add disks to create a larger volume. This includes setting up the array to still function after a disk failure by partially duplicating data. RAID has many different features that you can exploit thanks to using multiple disk controllers. RAID has been around for decades and is another virtualization process you can use to join disks to make larger arrays. Now that you’ve seen JBOD in detail, let’s dive into RAID configurations. Impossible parity checks because data isn’t duplicated across drivesĬompatible with software-based storage optimization toolsĪlthough it has disadvantages, JBOD is still a good choice. Lightweight because it only has one storage controller That means you can use fast and currently expensive M.2 storage more effectively. In this environment, you’ll use JBOD as it doesn’t duplicate storage controllers. If a disk fails, then you can replace it and add the source data back into the system. Rather, you want the speed of hot swapping it between processors and storage. In this use case, you’re not interested in keeping the data. Files can become huge, so it’s potentially better to deal with them as one file, instead of multiple smaller files. Yet, it originated in research departments where AI needed both fast and large storage volumes for big data handling. JBOD is just a load of disks! How Do You Use JBOD When one disk fills, the storage controller starts on the next disk, and so on. To do this efficiently, only one storage controller governs data entry on each disk. JBOD is a new way of virtualizing multiple physical drives into one volume. First, let’s delve into what JBOD is! What Is JBOD

In this article, we’ll take a look at both JBOD and RAID to see what are the benefits and drawbacks of each storage virtualization technology. This is because you need large quantities of performant and costly storage volumes to handle AI computation. In many cases, this has been attributed to the advent of artificial intelligence (AI) software. That’s because the redundant array of inexpensive disks (RAID) has smaller storage and more drive wastage. Just a bunch of disks (JBOD) has received a lot of attention recently.
