Pure Service Orchestrator (PSO) CSI Driver

What is PSO?

Pure Service Orchestrator (PSO) delivers storage-as-a-service for containers, giving developers the agility of public cloud with the reliability and security of on-premises infrastructure.

Smart Provisioning
PSO automatically makes the best provisioning decision for each storage request – in real-time – by assessing multiple factors such as performance load, the capacity and health of your arrays, and policy tags.

Elastic Scaling
Uniting all your Pure FlashArray™ and FlashBlade™ arrays on a single shared infrastructure, and supporting file and block as needed, PSO makes adding new arrays effortless, so you can scale as your environment grows.

Transparent Recovery
To ensure your services stay robust, PSO self-heals – so you’re protected against data corruption caused by issues such as node failure, array performance limits, and low disk space.

Software Pre-Requisites

• FlashArray User Privilages

  • It is recommend to use a specific FlashArray user, and associated API token, for PSO access control to enable easier array auditing.
  • The PSO user can be local or based on a Directory Service controlled account (assuming DS is configured on the array).
  • The PSO user requires a minimum role level of storage_admin.

• FlashBlade User Privileges

  • If the FlashBlade is configured to use Directory Services for array management, then a DS controlled account and its associated API token can be used for PSO.
  • The PSO user requires a minimum array management role level of storage_admin.
  • Currently there is no option to create additional local users on a FlashBlade.
