|
|
The 2.0.0 release of placement is the first release where placement is
|
|
available solely from its own project and must be installed separately from
|
|
nova. If the extracted placement is not already in use, prior to upgrading
|
|
to Train, the Stein version of placement must be installed. See
|
|
`Upgrading from Nova to Placement`_ for details.
|
|
|
|
2.0.0 adds a suite of features which, combined, enable targeting candidate
|
|
providers that have complex trees modeling NUMA layouts, multiple devices,
|
|
and networks where affinity between and grouping among the members of the
|
|
tree are required. These features will help to enable NFV and other high
|
|
performance workloads in the cloud.
|
|
|
|
Also added is support for forbidden aggregates which allows groups of
|
|
resource providers to only be used for specific purposes, such as reserving
|
|
a group of compute nodes for licensed workloads.
|
|
|
|
Extensive benchmarking and profiling have led to massive performance
|
|
enhancements, especially in environments with large numbers of resource
|
|
providers and high concurrency.
