Is anyone using JBOD on exchange journaling servers? If yes, how is that working out for you?

Hi mombu,

Microsoft does not support Exchange server deployed on JBOD storage architecture without DAG. JBOD have two main advantages: full space utilization and cost effective. However, if you lose a single disk in the JBOD then there is a high likelihood that you will lose data, as the concept of a JBOD does not include not fault tolerance.
So it is important to point out at this stage that JBODs should not be considered if you do not plan to use DAG.

More details about Exchange 2013 storage configuration and high availability, for your reference:

Thanks Allen. We plan to use JBOD, but looks like there is no specific guidance for journaling. Is anyone using JBOD for journaling servers that are part of DAG?

Hi mombu,

There are few documents related to JBOD and Exchange server journaling. Finally, I find an article about Storage Planning and Testing, for your reference:

Meanwhile, the below article is discussing about Exchange Server 2010 Design and Architecture at Microsoft with a example:

Thanks Allen,

These documents do not specifically call out journal databases. Is there any specific guidance for journaling databases and JBOD, has anyone used it or using it.
