Understanding the Software Configurations
that contains those specific 10GbE NIC and IB HCA cards. For example, looking at the
example configuration in the previous graphic, the VFs created on the last (right most) 10GbE
NIC and IB HCA will be associated with the last Root Domain.
I/O Domains
An I/O Domain is an SR-IOV domain that owns its own VFs, each of which is a virtual device
based on a PF in one of the Root Domains. Root domains function solely as a provider of VFs
to the I/O Domains, based on the physical I/O devices associated with each Root Domain.
Applications and zones are supported only in I/O Domains, not in Root Domains.
You can create multiple I/O Domains using the I/O Domain Creation tool. As part of the
domain creation process, you also associate one of the following SuperCluster-specific domain
types to each I/O Domain:
■
Application Domain running Oracle Solaris 11
■
Database Domain
Note that only Database Domains that are dedicated domains can host database zones. Database
I/O Domains cannot host database zones.
The CPU cores and memory resources owned by an I/O Domain are assigned from the CPU and
memory repositories (the cores and memory released from Root Domains on the system) when
an I/O Domain is created, as shown in the following graphic.
