JBOD Storage

JBOD chassis

JBOD storage system comprises a disk enclosure typically with a 6Gb/s or 12Gb/s SAS interface to which you connect to a RAID controller or SAS controller.  There are an increasing number of operating systems which require a JBOD rather than the traditional RAID storage and typically these operating systems create a software RAID across the drives either SSD or HDD. Some model storage systems also have multiple SAS ports for expansion so that you can daisy chain them together and protect the data with redundant paths, alternatively, you can connect them up to multiple hosts.

JBOD storage

A JBOD (just bunch of disks) offers no data protection against drive failure, this is achieved by using a RAID controller or disk redundancy is configured using 3rd party software.

Applications that require JBOD storage are Nexenta, Caringo, Scality, DataCore, Open-e etc.  These use software to create data protection on the storage and as well as protecting data across multiple JBOD chassis by writing the data multiple times.

Depending on the type of JBOD storage required and whether it has a single or dual SAS controller.  A dual controller will allow you to daisy chain up to 7 80 bay JBOD together.  This type of configuration can support over 240 drives that can be SSD, hard disks both SATA or SAS.  With a dual SAS controller-based system, would allow you to share the JBOD between a couple of host systems each with access to their own drives.  In addition to this, there is software available share all the storage using file locking software.

We provide Windows Server 2016/2019 & Windows Server 2016/2019 R2 certified JBOD solutions from 12-bay through to 80-bay with support for 12Gb/s SAS drives or SSD drives and 6Gb/s hard disks.

There are also news types of JBOD appearing these are JBOF (Just Bunch of Flash), these typically contain SSD or NVMe drives, some even connect using the newly announced interface NMVeOF (NVMe over fabric.  EBOD (Ethernet Bunch of drives), now the EBOD is very interesting as it doesn’t require a host to connect.  These will be increasingly used when Composable Infrastructure start to become more widely available.
