The Oracle Database Appliance storage is engineered and automatically configured for maximum stability, redundancy and performance. The pre-configuration of ASM results in greatly reducing Storage Administration tasks while optimizing the HW for speed, redundancy and stability. For this reason there are very few user defined storage choices and those that exist are set during the Deployment stage of the ODA. This note is the result of many common questions asked regarding Storage, ASM and the ODA. The scope of this note is limited up to 2.10 and X4-2 versions of the ODA although much of the content is generic to the ODA design.

Note: The ODA X5-2 (ODA HA) was originally released on The single-node ODA Lite series (X6-2 S/M/L) starts with ODA version While some of the information will apply to the ODA HA HW versions regarding redundancy and backups, please refer to the documentation for the most current storage options for your version of the ODA

There are currently two ASM storage configuration options which can only be defined and configured during the ODA deployment.

  1. Redundancy (The ASM default is High = 3x  or you can choose Normal = 2x)
    We have found that best practices in our user community are to use High (3x) redundancy for Production environments and optionally Normal (2x) for development and non-Production usage

  2. Local or external backup

There are two other features which will impact Storage availability and sizing

  1. A second JBOD (storage shelf) is available with the ODA  X3-2 and X4-2 installations which will double the total ASM physical storage mirroring diskgroup sizes for the first JBOD

  2. The ODA Virtualization Platform - ODAVP available as of ODA 2.5*
    * we will not be discussing ASM + ODAVP or ACFS in this note although there is some overlap
