This document applies to Oracle Linux configurations with external storage systems. This document is to be used by system design engineers and administrators planning for a new Oracle Linux system.
DM-MPIO stands for Device Mapper Multipathing I/O. Oracle Linux and RedHat Enterprise Linux (RHEL) includes the DM-MPIO technology which has been developed closely with vendors like EMC. DM-MPIO provides advantages listed below and not limited to:
User and kernel space tools for management and support
More flexibility when upgrading kernels as the DM-MPIO has been accepted upstream in the Linux kernel development team (i.e. updated drivers will be shipped with each updated kernel). On the other hand with proprietary drivers, a new driver package will be required for the new kernel version.
Boot-from-SAN support is much easier to setup with DM-MPIO
Multipathing support available during installation of OS
Hardware vendors are starting to recommend/support DM-MPIO in certain storage configurations
For more information on DM-MPIO and also for various cases / implementations see
There are various configurations which had been validated by Oracle / partners and customers are listed dynamically at Unbreakable Linux Network (ULN). For specific external storage (HP, EMC, NEC, Sun, Compellent, Dell, NetApp, Inspur, Pillar and more) configurations with Oracle Linux please:
