5 Understand the differences between bare-metal and
stateless deployments
Bare-metal and stateless are the two methods of deployment available from OME version 2.1 onwards. The
primary differentiator between these is who controls the virtual identities assigned to the device.
In bare-metal deployment, the user defines the identities and manually enters these into OME. This could also
be considered manual identity deployment. The benefits of this is that the user can choose exactly which
identity gets tied to each interface. The drawbacks are that the user must manually type this in and must also
make sure not to reuse an identity on multiple interfaces. Also, for this mode, the use of compute pools is
optional.
Stateless deployment allows the user to define a range of identities as a Virtual I/O pool, and then OME will
manage the assignment of the pool and automatically assign identities from the pool to devices. This
expedites the deployment process and removes the burden from the user for ensuring an identity is not
accidentally reused. Compute pools are required for this mode.
