Question 1

What Kubernetes standard does Pure Storage use to provide dynamic volume provisioning for containers on both FlashArray and FlashBlade?

Accepted Answer

Container Storage Interface (CSI)

Answer

Pure Storage implements the CSI standard (provisioner: csi.purestorage.com), allowing dynamic PersistentVolume provisioning from both FlashArray block and FlashBlade file storage.

Question 2

Pure Storage acquired which enterprise container data management company in 2020 to strengthen its Kubernetes storage portfolio?

Accepted Answer

Portworx

Answer

Pure Storage acquired Portworx in 2020, adding enterprise-grade container data services including storage orchestration, data protection, and disaster recovery for Kubernetes workloads.

Question 3

Which Kubernetes access mode does the Pure Storage CSI driver support for FlashArray block volumes?

Accepted Answer

ReadWriteOnce (RWO), allowing the volume to be mounted read-write by a single node

Answer

Block volumes on FlashArray support ReadWriteOnce because a block device can only be safely mounted to one node at a time; shared file access requires FlashBlade NFS.

Question 4

In a Kubernetes deployment with Pure Storage, what is the purpose of a StorageClass referencing the Pure Storage CSI provisioner?

Accepted Answer

It defines the backend array, access protocol, and parameters used when dynamically creating PersistentVolumes from PersistentVolumeClaims

Answer

A StorageClass specifies the Pure Storage provisioner along with parameters like backend (flasharray or flashblade), volume type, and mount options used for dynamic PV creation.

Question 5

Which Pure Storage product supports ReadWriteMany (RWX) access mode for shared persistent storage across multiple pods in Kubernetes?

Accepted Answer

FlashBlade, using NFS-based shared file storage

Answer

FlashBlade exports NFS shares that multiple pods on different nodes can mount simultaneously with read-write access, meeting the RWX requirement for shared workloads like AI/ML datasets.
