PowerFlex storage option

PowerFlex storage option

  • PowerFlex is a Dell storage product that is supported with VxRail dynamic cluster. PowerFlex systems provide IP-based storage to VxRail dynamic clusters that can be configured as primary storage for virtual machine workload.

    Figure 20.    VxRail dynamic cluster storage provided by PowerFlex virtual volume

    The PowerFlex system configures pools of storage through a virtualization process, and manages the allocation of virtual volumes to connected clients. Virtual volumes can be configured to meet certain capacity, performance, and scalability characteristics to align with the workload requirements planned for the VxRail dynamic cluster.

    The PowerFlex architecture combines both the compute and storage in a fabric-connected network architecture, with Dell PowerEdge servers serving as the hardware foundation for block storage capacity.

    If you plan to leverage virtual volumes provided by a PowerFlex system to serve as the primary storage for your VxRail dynamic cluster, ensure that best practices are followed to ensure a successful deployment:

    • Follow the guidance in the Dell PowerFlex Networking Best Practices and Considerations to ensure the supporting network infrastructure is properly planned and configured
    • Follow the steps in How to configure Dell PowerFlex Storage with VxRail Dynamic Nodes if you are unfamiliar with provisioning PowerFlex storage for this purpose
    • Reserve two Ethernet ports on each VxRail node planned for the dynamic cluster to support connectivity to the PowerFlex volumes serving as primary storage
    • Enable jumbo frames on the network configured to support VxRail dynamic cluster storage
    • After the VxRail dynamic cluster is built, plan to configure a separate virtual-distributed switch with new port groups in vCenter to support connectivity to the PowerFlex front-end system
