Everpure PX-CSI 26.3 Adds Cross-Array Snapshots for Kubernetes
Everpure has released PX-CSI 26.3, adding asynchronous snapshots between FlashArray systems and new storage, recovery and protocol controls for Kubernetes. The release is included with FlashArray and FlashBlade systems and supports both containers and KubeVirt VMs.
- FlashArray snapshots can be sent asynchronously to a second FlashArray.
- FlashBlade snapshots can be restored to new volumes.
- Kubernetes clusters can mix supported SAN protocols across nodes.
- PX-CSI 26.3 adds ARM64 support and managed file-service quotas.
- The release requires Portworx Operator 26.4.0 or later.
Cross-array protection and recovery
PX-CSI 26.3 can send FlashArray snapshots asynchronously to a second FlashArray system in the same Kubernetes cluster. The feature places a copy of data on separate hardware and requires Purity 6.6.1 or later on both arrays.
The release also allows FlashBlade snapshots to be restored to a new volume. This lets teams recover or test against a copy without overwriting the source file system. ActiveCluster stretched pods now work with FlashArray realms over iSCSI and Fibre Channel.
According to Everpure, combining realms with stretched pods provides zero-RPO and zero-RTO high availability for individual enterprise tenants while maintaining data separation. In the source, a realm is described as a secure boundary for managing storage for specific tenants or teams, while a stretched pod synchronously replicates storage objects between two FlashArray systems.
Mixed protocols and ARM64 support
PX-CSI 26.3 allows Kubernetes nodes in the same cluster to use different SAN protocols. Supported options include iSCSI, NVMe-TCP, NVMe-RoCE, NVMe-oF FC and Fibre Channel. Platform teams therefore do not need to standardize every node on one fabric before adding it to a cluster.
The release also supports Kubernetes running on ARM64 nodes. PX-CSI connects FlashArray, FlashBlade and Everpure Cloud Dedicated to clusters through the standard Container Storage Interface, managing volume provisioning, attachment, resizing, snapshots and deletion.
More controls for platform teams
Persistent volume claims on FlashArray File Services now receive a managed quota matching the requested size. A new StorageClass parameter can pin FlashArray File Services volumes to a specific NFS server for per-class data isolation, although that capability requires Purity 6.8.7 or later.
PX-CSI 26.3 also adds TLS certificate verification for management API connections to FlashArray and FlashBlade, including certificates signed by a private certificate authority. Administrators can take an array out of new provisioning while existing volumes continue working, and can configure deleted volumes for immediate eradication instead of leaving them in the pending eradication queue.
What the release means for Kubernetes users
PX-CSI extends FlashArray and FlashBlade capabilities to Kubernetes through standard Kubernetes objects. That gives storage teams access to replication, multi-tenancy and security controls, while developers can request volumes without filing a storage ticket, according to Everpure.
PX-CSI 26.3 requires Portworx Operator 26.4.0 or later. Everpure says teams can install it for new deployments or upgrade existing PX-CSI installations, with the full list of changes and requirements available in the PX-CSI 26.3 release notes. The driver runs on Red Hat OpenShift, with the support matrix listing OCP 4.19 to 4.22 for 26.3.
