Deployment Options
|
|
==================
|
|
|
|
A variety of |prod-long| deployment configuration options are supported.
|
|
|
|
**All-in-one Simplex**
|
|
A single physical server providing all three cloud functions \(controller,
|
|
worker and storage\).
|
|
|
|
**All-in-one Duplex \(up to 50 worker nodes\)**
|
|
Two HA-protected physical servers, both running all three cloud functions
|
|
\(controller, worker and storage\), optionally with up to 50 worker nodes
|
|
added to the cluster.
|
|
|
|
**Standard with Storage Cluster on Controller Nodes**
|
|
A two node HA controller + storage node cluster, managing up to 200 worker
|
|
nodes.
|
|
|
|
**Standard with Storage Cluster on dedicated Storage Nodes**
|
|
A two node HA controller node cluster with a 2-9 node Ceph storage
|
|
cluster, managing up to 200 worker nodes.
|
|
|
|
.. note::
|
|
A storage backend is not configured by default. You can use either
|
|
internal Ceph or an external Netapp Trident backend.

|
All |prod| systems can use worker platforms \(worker hosts, or the worker
|
|
function on a simplex or duplex system\) configured for either standard or
|
|
low-latency performance.
