  1. Advantages of using JBOD Storage and How to Achieve its Best Performance and Reliability?

  2. Just a Bunch of Disks or JBOD is an architecture which combines multiple drives together in order to form either a single or a group of logical volumes (which is also known as “spanning”) or make them accessible as independent hard disk drives. Advantages of JBOD There are two main advantages of using JBOD storage: Full space utilization: Unlike many RAID configurations JBOD doesn’t limit you to the size of the smallest disk with the array (in fact, in any RAID array you shouldn’t mix different disk sizes) – a JBOD configuration allow for the combined space of all the drives to be used by the end Operating System.

  3. Cost-effective: Basic SATA disks & Controllers are cheap when compared to their SCSI, SAS, and Hardware RAID cousins – thus, if you are looking for storage architecture on a budget and you are sure that your backup provision is watertight then you should consider JBOD storage. How to achieve the best performance and reliability? The following three components are the key factors when it comes to choosing and configuring a JBOD: Connectivity: Passing a large amount of data through a small cable can be challenging, especially when you are trying to achieve the high read/write performance. The table below shows

  4. the summary of the compromises of each connectivity type that are often found on JBOD systems: Performance Cost High Low High Distance Long Long Long Fibre Channel GbE iSCSI 10 GbE iSCSI SAS2 6Gb/s (SFF- 8088) SAS3 (SFF-8644) QSFP+ (up to 48Gb/s) High Low High Low Low Short 12Gb/s High Low Short Very High Medium Long Expanders: The SAS expander is a chip which is installed on the chassis backplane that functions as a switch, multiplying the number of supported drives. Thus, JBODs with two

  5. expanders will increase redundancy, and it's read & write performance by load-balancing the data stream on two links instead of just one (more bandwidth) and thereby reducing the bottleneck. Drives: Due to the high number of drives, JBOD storage is often made of mechanical drives. These are the key components of the storage unit. Expect them to fail every now & then or to add new ones for expanding the capacity of the JBOD. While considering the speed and capacity of the drive, it is crucial not to overlook its reliability.
