Object Storage Setup
The dialogs for each step can be found through the Getting Started dialog or from toolbar dialogs. I will demonstrate each path in the sections below. We recommend the Getting Started path for initial creation since it walks you through the proper order of installation.

Create Object Storage Cluster
QuantaStor leverages open storage Ceph technology to deliver Scale-out Object Storage (S3/SWIFT) and Scale-out Block Storage (iSCSI). Before provisioning scale-out storage solutions, one must set up one or more Ceph Clusters within a QuantaStor storage grid. Ceph Clusters should be comprised of at least three (3) or more Storage Systems within the grid. It is possible to create a single-node Ceph Cluster, but these are recommended only for test configurations.
Note also that one should set up the network ports on each System so that a dedicated high speed back-end network may be used for inter-node communication. This back-end network is recommended to have double the bandwidth of the front-end network. Both the front-end and back-end network ports should bonded ports for improved performance and high-availability. The same network may be used for the front-end and back-end network but this is not optimal.

Select Data Devices
Scale-out Storage Pools and Zones store their data in object storage devices called OSDs (Object Storage Daemon). Each Physical Disk assigned to the Ceph Cluster as a data device becomes an OSD. To accelerate write performance each System must have at least one SSD device assigned as a WAL (Write-Ahead Logging) Device. All writes are logged to an OSD's associated WAL Device first. Press the button to the left to add OSDs and WAL devices to the Ceph Cluster. Note, using the "Auto Config" button, highlighted in red, makes the proper selections for you.

Create S3 Object Storage Zone
To access the cluster via the S3 object storage protocols a Zone must be created. Press the button "Create Object Storage Pool" to create an S3 object storage pool and a zone within the cluster.
- or -
Add S3 Gateways
Select the Ceph Cluster to add a new S3 Gateway to and specify the network interface configuration.
- or -
Add S3 Users
After the Zone has been created users must be given an access key and secret key in order to create buckets and objects via the S3 protocols. Press the button to the left to add a S3 Object User Access Entry to the Zone.

Create S3 Bucket
Create one or more buckets for writing object storage via the S3 protocol.
