Cloud Controller:
CPU – Has an x86 or SPARC server or a virtual machine that has at least a 2 Ghz processor.
RAM – Has at least 16 Gbytes of RAM.
Disk – Has at least one Tbyte of disk space if the cloud controller also acts as a Cinder volume storage provider, else you can use 146-300 Gbytes of local storage.
Compute Node:
CPU – A sun4v platform that runs at least an UltraSPARC T2 server is required. It is best to use at least a SPARC T4 series server.
RAM – Has at least 128 GBytes of RAM. Assign at least eight Gbytes to the control domain or 16 Gbytes when using local ZFS volumes.
Disk – Has at least 300 Gbytes of disk space plus local storage for virtual machines if you use local files or ZFS volumes.
Network – Configures the network by using the DefaultFixed network configuration profile on the control domain.
Nodes – Requires at least two compute nodes for live migration. If the compute nodes are different platform types, specify the appropriate cpu-arch value for the virtual machines that you want to migrate. See Creating Oracle VM Server for SPARC OpenStack Compute Node Flavors.
Cloud controller and compute nodes:
Runs at least the Oracle Solaris 11.3 SRU 12 OS.
The cloud controller OS must supply at least the same OpenStack release as is being used on the compute nodes. For this release, it is the OpenStack Kilo release.
Guest domains:
Runs at least the Oracle Solaris 10 1/13 OS, the Oracle Solaris 11 OS, or the Linux for SPARC 1.0 OS.
The Oracle Solaris 10 1/13 OS, Oracle Solaris 11.2 OS, Oracle Solaris 11.3 SRU 12 OS, and the Linux for SPARC 1.0 OS have been validated.
The distributed lock manager is optional. However, if you use DLM, it has the following prerequisites:
Requires a highly available NFSv4 server that is external to the compute nodes.
Requires a single NFSv4 share that has at least one Gbyte of free space.
Requires that delegation is disabled on the NFSv4 share.
Requires that the NFSv4 share is read-write for both the root user (UID 0) and the nova user (UID 85, GID 85).
