JBOD storage systems
A 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 JBOD storage 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.
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 such as a software defined storage solution from DataCore.
Applications that require JBOD storage are Nutanix, 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 and whether it has a single or dual SAS controller will allow you to daisy chain them 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 2012 & Windows Server 2012 R2 certified JBOD storage solutions from 12-bay through to 80-bay with support for 12Gb/s SAS drives or SSD drives and 6Gb/s hard disks.
