Rather than configuring a storage array to use a RAID level, the disks within the array are either spanned or treated as independent disks.\u00a0Spanning\u00a0configurations use a technique called\u00a0concatenation\u00a0to combine the capacity of all of the disks into a single, large logical disk. Although some RAID levels also concatenate disks, numbered RAID levels generally use striping or\u00a0parity\u00a0while JBOD does not.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/cdn.ttgtmedia.com\/rms\/onlineImages\/JBOD.jpg\" alt=\"\"\/><\/figure>\n\n\n\n<p>JBOD means the individual disks are presented (to a\u00a0server) with no amalgamation, pooling or structure applied.
