All-in-one (AIO) Simplex Configuration
|
|
======================================
|
|
|
|
The AIO Simplex deployment configuration provides a scaled-down |prod| that
|
|
combines controller, storage, and worker functionality on a single
|
|
non-redundant host.

|
.. note::
|
|
Physical L2 switches are not shown in this deployment diagram and in
|
|
subsequent deployment diagrams. Only the L2 networks they support are
|
|
shown.
|
|
|
|
See :ref:`Common Components <common-components>` for a description of common
|
|
components of this deployment configuration.
|
|
|
|
This deployment configuration provides no protection against an overall server
|
|
hardware fault. However, there may be hardware component protection if, for
|
|
example, HW RAID or 2x Port |LAG| is used in the
|
|
deployment.
|
|
|
|
Typically, this solution is used where only a small amount of cloud processing
|
|
/ storage power is required, and protection against overall server hardware
|
|
faults is either not required or done at a higher level.
|
|
|
|
Optionally, Ceph is deployed in this configuration using one or more disks for |OSDs|, and
|
|
provides the backend for Kubernetes' |PVCs|.
|
|
|
|
Typically, the solution requires two or more disks, one for system requirements and
|
|
container ephemeral storage, and one or more for Ceph |OSDs|.
|
|
|
|
Optionally, instead of using an internal Ceph cluster on the server, you can
|
|
configure an external Netapp Trident storage backend.
|
|
|
|
.. xreflink .. note::
|
|
A storage backend is not configured by default. You can use either
|
|
internal Ceph or an external Netapp Trident backend. For more information,
|
|
see the :ref:`|stor-doc| <storage-configuration-storage-resources>` guide.
|
|
|
|
The internal management network is not required in this scenario as it is
|
|
configured on the loopback interface. The cluster host network is internal by
|
|
default and also configured on the loopback interface with application
|
|
container external connectivity being achieved through either the external OAM
|
|
network or optional additional external networks. However, the cluster host
|
|
network can be re-configured on a physical interface depending on external
|
|
connectivity requirements.

Intel Xeon D Processor
|
|
----------------------
|
|
|
|
In addition to regular all-in-one deployments, |prod| Simplex and Duplex
|
|
provide support for small scale deployments on the Intel Xeon D family of
|
|
processors using a smaller memory and CPU footprint than the standard Simplex
|
|
configuration.
|
|
|
|
For low-cost or low-power applications with minimal performance demands \(40
|
|
Containers or fewer\), |prod| Simplex can be deployed on a server with a
|
|
single Intel Xeon D class processor. The platform-reserved memory and the
|
|
maximum number of worker threads are reduced by default, but can be
|
|
reconfigured as required.
