JBOD enclosures and most RAID levels allow for hot swapping, meaning a drive in the enclosure or array can be replaced without shutting down the host system. This is especially useful in programs and applications where users need frequent access to data stored on various servers. Shutting down an entire system for drive replacement increases organizational downtime, and in turn, decreases productivity. In mission-critical programs and applications, significant downtime and decreased productivity may have catastrophic consequences, such as financial loss, public outcry, serious injury and even death.
And when it calls for tons of storage, crazy fast read and write speeds and easy drive swap in a lightweight, rugged chassis, you know where to find us. Our rugged JBOD enclosures just might be the right choice for you. Blogs by Trenton Systems. JBOD vs. Well, when it comes to JBOD, the name pretty much says it all. Simply put, JBOD architecture lets you take a group of motley hard drives of various sizes and makes and configure them into either a single logical volume or into a group of individual hard drives.
While partitioning chops single drives into smaller logical volumes, JBOD combines drives into larger logical volumes. You can immediately forget about any guarantee of information security, as the normal mode of operation stops when any number of disks fails. This is truly the most economical way to increase space. Disk space is formed by the sequential combination of disks; no block rotations or checksums are used.
It should be noted that if some drive fails, not all data may be lost, but this is a dubious advantage. It is a data virtualization technology that also integrates multiple drives into a logical element. However, this does not happen simply to increase space but to create redundancy and increase productivity, increase fault tolerance, and more. Accordingly, there is a minimum of required disks: 2 or more, depending on the type of array.
RAID has a fairly widespread use, both in-home use and in large offices, all this due to the diversity of its types. The lack of fault tolerance or redundancy in JBOD leads to the fact that work stops when even one drive fails. Therefore, when using this technology, backups of important data should be made with a certain frequency.
Yet as data centers scale to petabyte, exabytes and beyond, RAID is seeing challenges to scale for big data demands. For this reason, JBOD configurations and object storage are becoming a key staples of data centers as data grows in volume and becomes more distributed globally. JBODs are also becoming more popular as modern file systems and software-defined storage solutions are becoming far more mature and are able to provide data protection capabilities.
Supporting technologies to ensure data availability in the event of an individual disk failure — such as erasure coding and other backup technologies, are becoming more sophisticated and alleviating some pain points typically that have been associated with JBOD configurations.
