‘Just a Bunch of Disks’ or JBOD refers to a collection of hard disks that have not yet been configured, to act as a redundant array of independent disks (RAID).
They are individual disks that make up a server, before they have had any amalgamation, pooling or structure applied. While partitioning chops single drives into smaller logical volumes, JBOD combines multiple drives into larger logical volumes utilising Microsoft storage space technology.
Benefits of JBOD
JBOD’s are useful when you have a lot of data to store, JBOD’s are an economical solution compared RAID storage. Using Microsoft storage space technology you are able to deploy inexpensive, reliable cluster-connected storage. You can use storage spaces along with failover clustering and cluster shared volumes across multiple jbod’s to create a scale-out file server a highly-available cluster with high volumes of resilient storage available for data and virtual servers.
JBOD and Microsoft
JBODs are used in conjunction with Microsoft storage spaces, so it is important that you use Windows Server certified JBOD enclosures, Midshire the only UK provider of DataON servers, which are Certified JBOD Enclosures.
JBODs tend to be simple to understand and set up. It’s also relatively straightforward to add storage capacity in a JBOD system, you simply add another drive. People who like flexibility in their workflows want tight control of their data storage and backup strategies, or simply prefer reducing the clutter of multiple external disk drives on their desks, tend to use JBOD enclosures.
It is important to remember that whether you are using JBOD or RAID storage architectures, always ensure that data is being backed up to at least one other drive or location.
Avoiding Drive Waste
If your server is made up of a number of odd-sized drives, you can combine them into a single unit without loss of any capacity with JBOD. For example, a 250GB drive and a 300GB drive would combine to make a 550GB JBOD volume. Additionally vs RAID array there is no disk redundancy.
