OpenShift Container Platform can provision raw block volumes. These volumes do not have a file system, and can provide performance benefits for applications that either write to the disk directly or implement their own storage service.
There are 2 types of storage connectivity and 2 levels of storage in each. All block storage is located on a NetApp appliance.
The two types of storage connectivity are:
- NFS
-
is the default storage type
- iSCSI
-
storage should only be used for database type applications
See Block Volume storage support for more information.
