Generic concepts and components
|
|
-------------------------------
|
|
|
|
Following picture shows a conceptual view of the relationship between any OpenStack solution and z/VM.
|
|
|
|
An OpenStack solution is free to run its components wherever it wishes; its options range from running
|
|
all components on z/VM, to running some on z/VM and others elsewhere, to running all components on
|
|
other platform(s). The solution is also free to source its components wherever it wishes, either using
|
|
z/VM. OpenStack enablement components or not.
|
|
|
|
z/VM ships a set of servers that provide local system management APIs. These servers consist of request
|
|
servers that accept local connections, receive the data, and then call one of a set of worker servers to
|
|
process the request. These servers are known collectively as SMAPI. The worker servers can interact with
|
|
the z/VM hypervisor (CP) or with a directory manager. A directory manager is required for this
|
|
environment.
|
|
|
|
Overall architecture
|
|
--------------------
|
|
|
|
z/VM openstack enablement rely on z/VM cloud connector, the compute service (nova-compute) can either
|
|
run on remote server other than z/VM itself or run on top of virtual server which hosted on z/VM.

Function Call flow
|
|
------------------
|
|
|
|
Following is a picture describe the call routine of spawn function,
|
|
openstack zvm driver managed zvm through REST API call provided by
|
|
zvm cloud connector.
