= CSI architecture
|
|
|
|
CSI drivers are typically shipped as container images. These containers
|
|
are not aware of {product-title} where they run. To use CSI-compatible
|
|
storage back end in {product-title}, the cluster administrator must deploy
|
|
several components that serve as a bridge between {product-title} and the
|
|
storage driver.
|
|
|
|
The following diagram provides a high-level overview about the components
|
|
running in pods in the {product-title} cluster.

|
|
It is possible to run multiple CSI drivers for different storage back ends.
|
|
Each driver needs its own external controllers deployment and daemon set
|
|
with the driver and CSI registrar.
