What is JBOD in Linux?

JBOD refers to the single-disk operating mode that many hardware RAID controllers support. With JBOD mode, the controller is able to circumvent RAID firmware and treat a single hard disk as a normal disk controller would.

What is JBOD used for?

JBOD drives are individual drives, meaning that each drive in your system is seen by your computer as an individual disk volume. JBOD drives allow you to easily add additional storage to your system – just connect another drive – and allows for easy to manage, and less expensive backup solutions.

Is JBOD a RAID?

JBOD, which stands for Just a Bunch of Disks or Just a Bunch of Drives, is a storage architecture consisting of numerous disk drives inside of a single storage enclosure. JBOD enclosures are usually not configured to act as a RAID, but they can be.

Is JBOD a redundancy?

JBOD. JBOD (abbreviated from “Just a Bunch Of Disks”/”Just a Bunch Of Drives”) is an architecture using multiple hard drives exposed as individual devices. A spanned volume provides no redundancy, so failure of a single hard drive amounts to failure of the whole logical volume.

Does JBOD provide redundancy?

Redundancy and Availability While JBOD can provide redundancy for components such as power supplies and cooling fans, there is none at the disk level. What this essentially means is that if a disk in an array fails, you will lose any data that does not have a backup.

What is just a bunch of disks (JBOD)?

JBOD is short for Just a Bunch of Disks or Just a Bunch of Drives, which is a storage structure including multiple disk drives within one single storage enclosure. It refers to the hard disks on the computer that haven’t been configured in terms of RAID (Redundant Arrays of Independent Disks).

What is a JBOD drive?

It refers to the hard disks on the computer that haven’t been configured in terms of RAID (Redundant Arrays of Independent Disks). JBOD drives are individual drives, which means that drives in JBOD enclosure can function individually. And they configured to act as RAID under the help of correct host system technology. -image from wikipedia.com

What is the difference between raid and JBOD?

The RAID stores the same data repeatedly on multiple disks. However, these disks will be appeared on the operating system like a single disk. Similarly, JBOD makes the disks display on the OS as a single disk. Differently, JBOD will combine the drives into one larger logical one.

Is JBOD fault-tolerant?

Though RAID isn’t fault-tolerant neither, it offers performance enhancement compared with individual hard drives or JBOD. Tip: Compared with a single disk, JBOD doesn’t have any advantages for it will not offer you any fault tolerance or performance improvement like RAID. What is JBOD? The above content is the basic information of JBOD.
