Version: 3.4

System Requirements

Before installing Portworx Enterprise, ensure your environment meets the minimum requirements for a stable and supported deployment. A Portworx cluster must include at least three nodes, each meeting specific hardware, software, and network requirements.

Hardware requirements​

Each node in the Portworx cluster must meet baseline hardware specifications. These vary slightly depending on whether you're using PX-StoreV1 or PX-StoreV2. Requirements include CPU, RAM, disk space and storage drive configuration to ensure optimal operation.

Hardware Requirements
CPUMinimum 4 Cores | Recommended 8 Cores
RAMMinimum 4GB | Recommended 8GB
Disk
  • /var - Recommended 30GB Free
  • /opt - Minimum 3.5GB Free
    • Backing drive8GB (minimum required)
    128GB (minimum recommended)
    Operating system root partition
  • 64GB is the minimum required size for the root filesystem, which contains the operating system.
    • 128GB minimum recommended
    Storage drivesStorage drives must be unmounted block storage: raw disks, drive partitions, LVM, or cloud block storage.
    Network connectivity

    Bandwidth:

    • 10 Gbps recommended
    • 1 Gbps minimum
    Latency requirements for synchronous replication: less than 10ms between nodes in the cluster.

    Node typeBare metal and virtual machine (VM)

    Software requirements​

    Each node in the Portworx cluster must meet the necessary software requirements, including a supported Linux kernel version, container runtime, and key-value store configuration. Portworx also depends on specific system utilities and settings, such as having swap disabled and NTP enabled, to ensure reliable and consistent cluster behavior.

    SoftwareRequirements
    Linux kernel and distro

    Kernel version 4.18 or greater.
    To check if your Linux distro and kernel are supported, see Supported Kernels.

    DockerVersion 1.13.1 or greater.
    Key-value store

    Portworx needs a key-value store to perform its operations. As such, install a clustered key-value database (kvdb) with a three-node cluster.

    You can also use Internal KVDB during installation. In this mode, Portworx will create and manage an internal key-value store (KVDB) cluster.

    If you plan to use your own KVDB, refer to KVDB for Portworx for details on recommendations for installing and configuring a KVDB cluster.

    Disable swap

    Disable swap on all nodes that will run the Portworx software. Ensure that the swap device is not automatically mounted on server reboot.

    Network Time Protocol (NTP)

    All nodes in the cluster should be in sync with NTP time. Any time drift between nodes can cause unexpected behavior, impacting services.

    Supported hypervisor version​

    Hypervisor
    VMware vSphere
    • Version 7.0
    • Version 8.0

    Network requirements​

    Portworx runs as a pod in a Kubernetes cluster and requires specific ports to be open for node communication, storage operations, and telemetry. These vary slightly between Kubernetes and OpenShift environments.

    Supported Kubernetes versions​

    Portworx by Pure Storage recommends that you only upgrade to an OpenShift version and Kubernetes version that is listed here. Do not upgrade to a more recent version that is not listed here.

    Before you install Portworx on any environment, ensure that you're using a supported environment version:

    If your Kubernetes distribution supports multiple Linux distributions and kernel versions, refer to the Supported kernels page to ensure that your kernel version is supported.

    note

    Portworx Enterprise 3.4.0 now support Kubernetes version 1.33. Before upgrading to Kubernetes 1.33 or later, update the Portworx Operator to 25.3.1 or above and Portworx Stork version to 25.4.0 or later.
