System features

  • PowerFlex appliance uses PowerFlex, which uses the local disks of existing PowerFlex nodes to create a storage pool. It is designed to scale to thousands of PowerFlex nodes.

    The integrated scalable network architecture is available with a choice of the following:

    • Hardware consisting of either Cisco Nexus switches or Dell EMC PowerSwitch switches

    • Bandwidth depending on the customer needs

    • Complete flexibility in designing the converged system with the following options:

      • PowerFlex hyperconverged nodes
      • PowerFlex storage-only nodes
      • PowerFlex compute-only nodes

    • Supports 25 GbE or 100 GbE port activity for backend connectivity

    • Supports native asynchronous replication between sites (PowerFlex storage-only nodes are only supported at this time)

    • PowerFlex nodes supports SSD and NVMe drive technologies

    • Improved node maintenance using protected maintenance mode (PMM)

    • Supports self-encrypting drives (SEDs) enabled by Dell EMC CloudLink

    • Supports horizontal scaling by adding PowerFlex nodes to extend storage or compute capacity

    • Secure and scalable storage using PowerFlex

      • Seamlessly increase storage capacity or performance with horizontal node scaling
      • Optional data compression feature that improves storage efficiency
      • Optional Data at Rest Encryption (D@RE) feature provides data security using CloudLink as a software encryption layer, or as a key manager for self-encrypting drives

    • End-to-end life cycle management with PowerFlex Manager

    • An optional PowerFlex management node is also available to act as a host for PowerFlex management applications. The PowerFlex management node is based on the PowerFlex R640 node and includes hardware RAID disk redundancy.
