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】.

To collect a comprehensive support bundle for Portworx Autopilot, the proper procedure is to create a dedicated directory, send a support signal to the running Autopilot process to trigger diagnostics collection, and then the generated support bundle files from that directory. This approach ensures all relevant Autopilot logs, configuration files, and runtime metrics are gathered in a structured way, enabling effective troubleshooting and root cause analysis. Simply restarting or deleting pods is insufficient, as it does not guarantee a full diagnostics capture. The Portworx troubleshooting and support documentation outlines this method as the standard for collecting detailed Autopilot support information, facilitating accelerated support response and issue resolution in production clusters【Pure Storage Portworx Support Guide†source】.

Enabling Alertmanager in Portworx involves creating a Kubernetes Secret containing the Alertmanager configuration (such as alert routing rules and notification channels) and referencing this secret in the Portworx StorageCluster manifest. This integration allows Portworx’s monitoring stack to forward alerts to Alertmanager for centralized alert processing and notifications. Unlike ConfigMaps, which are generally used for non-sensitive data, Secrets protect sensitive alert configuration. Enabling Alertmanager via pxctl CLI is not supported as Portworx relies on Kubernetes declarative configuration for monitoring components. Additionally, deploying Alertmanager independently and integrating through webhooks requires manual setup but is not the recommended or integrated approach. Portworx official observability documentation details the secret-based configuration as the standard and secure method to enable and manage Alertmanager within Portworx clusters for robust alert handling【Pure Storage Portworx Monitoring Guide†source】.

When using Portworx Asynchronous Disaster Recovery (DR) to migrate workloads and storage across clusters, network policies can sometimes interfere with seamless failover. The label skipNetworkPolicyCheck: true can be used to instruct the DR mechanism to bypass strict network policy checks during migration. This allows applications and volumes to migrate even if network policies differ or are incompatible between source and destination clusters. Without this label, migration might be blocked or fail due to network restrictions. By default, network policies are not always migrated, and strict checks are performed unless explicitly skipped. Portworx DR documentation details this option as a means to increase migration flexibility, reduce operational friction, and enable faster recovery during disaster scenarios while administrators work on aligning network configurations【Pure Storage Portworx DR Guide†source】.

To view detailed information about storage pools in a Portworx cluster—including size, availability, usage, and health—administrators should use the command pxctl service pool show. This CLI command provides a comprehensive overview of all storage pools configured on cluster nodes, including pool IDs, device names, pool sizes, free space, and status. It helps administrators monitor resource utilization, detect degraded pools, and plan capacity expansions. While kubectl get storagecluster shows the overall cluster CRD status and pxctl cluster provision-status shows provisioning status, neither provides detailed pool-level insights. Portworx’s operational documentation recommends pxctl service pool show as the definitive command for monitoring pool resources and ensuring storage health across the cluster【Pure Storage Portworx CLI Guide†source】.

Skinny Snapshots are a space-efficient snapshot technique used by Portworx for replicated volumes (Repl 2 or 3) when storage capacity is limited and no external Object Store is configured. Unlike full snapshots that duplicate data blocks, skinny snapshots capture only the differences (deltas) since the last snapshot, minimizing space consumption. This method allows administrators to take frequent snapshots without significantly impacting storage availability. Skinny Snapshots are particularly useful for on-premises environments or clusters without access to cloud object storage, balancing snapshot granularity with resource constraints. Official Portworx snapshot documentation explains how skinny snapshots work internally, improving backup and recovery capabilities under tight storage conditions without requiring cloud integration【Pure Storage Portworx Snapshot Guide†source】.

The ApplicationRestore Custom Resource Definition (CRD) object in Portworx is specifically designed to restore an application from an existing ApplicationBackup. This object orchestrates the process of recovering a consistent snapshot of an application, including all its associated volumes, in Kubernetes environments. Using ApplicationRestore, administrators can define the source backup, restore location, and any necessary transformations during restoration. This facilitates disaster recovery, migration, or rollback scenarios for complex stateful applications. The Portworx backup and restore documentation clearly defines ApplicationRestore as the controller responsible for application-level recovery operations, ensuring data integrity and consistency throughout the restore workflow【Pure Storage Portworx Backup and Restore Guide†source】.

To verify a Portworx upgrade on Kubernetes, administrators use the pxctl get storagenodes command. This Portworx CLI command lists all storage nodes with detailed information including version, status, and health. By inspecting the version column, administrators can confirm whether all nodes have been successfully upgraded to the desired Portworx release. This command specifically queries Portworx daemons for accurate cluster version details, unlike kubectl get nodes which shows Kubernetes node info but not Portworx versioning. Portworx upgrade best practices stress using pxctl commands for detailed verification after an upgrade to ensure consistent cluster software versions and successful upgrade completion【Pure Storage Portworx Upgrade Guide†source】.

Portworx requires swap to be disabled on Linux hosts where it runs. Disabling swap is necessary because swap usage can cause unpredictable latency and performance degradation for storage operations. Portworx relies on consistent and predictable I/O performance for managing block devices and volumes, which is incompatible with the potential delays caused by swapping memory pages to disk. Additionally, many Kubernetes environments recommend disabling swap to meet Kubernetes scheduler requirements, aligning with Portworx’s needs. Portworx installation and system requirements documentation explicitly state that swap should be disabled on nodes running Portworx to ensure cluster stability, optimal performance, and predictable behavior of storage operations【Pure Storage Portworx System Requirements†source】.
