Pure Storage Portworx-Enterprise-Professional Dumps Questions Answers

Comprehensive and Detailed Explanation From Exact Extract:

Portworx primarily supports deployment on Kubernetes and is well-integrated with major cloud platforms including Amazon Web Services (AWS). AWS offers native infrastructure and storage services that complement Portworx’s capabilities for cloud-native storage, including integration with Elastic Block Store (EBS) and S3 Object Storage. While Portworx historically supported container orchestrators like Docker Swarm and Mesosphere DC/OS (DCOS), the primary and recommended platform for production deployments today is Kubernetes on cloud providers such as AWS, Azure, and Google Cloud. AWS’s ecosystem allows Portworx to leverage scalable compute and storage infrastructure, advanced networking, and cloud security features, making it a preferred platform. Portworx official platform support documentation lists AWS as a key supported environment for its container storage solutions【Pure Storage Portworx Platform Support Guide†source】.

Portworx primarily relies on Direct Attached Storage (DAS) for its storage provisioning. DAS refers to physical disks or SSDs directly connected to the nodes running Portworx. Using DAS enables high-performance, low-latency access to storage resources, crucial for stateful containerized applications. Portworx aggregates and abstracts these local devices into distributed storage pools, providing features like replication, encryption, and snapshots. While Portworx integrates with Object Storage for cloud snapshots and disaster recovery, and can support NFS for certain use cases, the core storage provisioning and volume management depend on DAS. The Portworx architecture documentation clarifies that leveraging local node storage is essential for delivering performant, resilient, and scalable persistent storage in Kubernetes environments【Pure Storage Portworx Architecture Guide†source】.

When integrating Portworx with an S3 Object Store secured by a custom or third-party certificate that is not signed by a public Certificate Authority (CA), administrators must manually provide the relevant CA certificate to Portworx. This involves creating a Kubernetes secret that contains the custom CA certificate and referencing this secret in the StorageCluster manifest through environment variables. This allows Portworx components to trust the certificate during TLS handshake with the S3 endpoint, avoiding connection failures due to untrusted certificates. Without this step, Portworx cannot securely communicate with the object store. The Portworx security and installation documentation highlights this practice as essential for secure Object Store integration in private or regulated environments where internal or custom PKIs are used【Pure Storage Portworx Security Guide†source】.
