To use Portworx as a storage
option, you must manually create two storage classes: one for system and backup data (rwx) and one
for user data (rwo).
About this task
For the Portworx storage option, note
that you must use split (not single) storage, and you must specify 4K block size for user data.
Along with the deployment requirements listed in the Certified Storage table for setting up Portworx storage, you must also ensure that there is
a minimum of 1 TB of raw, unformatted disk space on every compute node that is designated for
storage. The raw disk must have the same device name on all worker nodes.
