What is JBOD storage?
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. By their very nature, JBOD enclosures are storage capacity monoliths.
What is a ZFS storage Pool?
Instead of forcing you to create virtualized volumes, ZFS aggregates devices into a storage pool. The storage pool describes the physical characteristics of the storage (device layout, data redundancy, and so on) and acts as an arbitrary data store from which file systems can be created.
How does JBOD write data?
In a JBOD storage architecture, multiple hard drives or solid-state drives (SSDs) are placed together in a single housing. Data is written to a JBOD configuration in a sequential way, avoiding the more complex steps involved in writing data seen in redundant array of independent disks (RAID) systems.
What is the benefit of JBOD disk configuration?
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.
What is JBOD controller?
JBOD stands for “just a bunch of drives”. JBOD mode passes through physical disks so that the operating system or host can see each individual drive. This is the opposite of a normal RAID controller, which groups physical disks together to form a single, often larger or fault tolerance, virtual drive.
Is JBOD faster than RAID 0?
The difference comes down to what you need: RAID 0 provides better performance by spreading data across multiple drives in the RAID for faster writing and reading. This is important for high audio track counts and video applications. JBOD creates one large “logical” drive from several smaller drives.
What is the full form of ZFS?
ZFS stands for Zettabyte File System and is a next generation file system originally developed by Sun Microsystems for building next generation NAS solutions with better security, reliability and performance.
Why is ZFS so good?
Huge Storage potential When ZFS was created, it was designed to be the last word in file systems. At a time when most file systems where 64-bit, the ZFS creators decided to jump right to 128-bit to future proof it. This means that ZFS “offers 16 billion billion times the capacity of 32- or 64-bit systems”.

How does ZFS protect your data?
ZFS protects your data by enabling volume management on filesystem level. This feature makes “Copy on Write” (CoW) technology possible. When a block of data is altered, it will change its current location on the disk before the new write is finished.
