Introduction

  • PowerStore supports iSCSI and Fibre Channel (FC) hosts. NVMe over Fibre Channel (NVMe/FC) is supported with PowerStoreOS 2.0. These protocols can be run simultaneously, but this configuration can add complexity to routing and failover scenarios. It is recommended to configure a host to use only one protocol. Hosts in a clustered environment should also be configured to use only one protocol.

    For this configuration, a converged Ethernet environment is used to provide block storage (iSCSI) and file storage (SMB). FC or NVMe/FC and can also be used to provide block storage. One advantage to using a converged Ethernet configuration is reduced complexity and cost. Small office, branch office, and edge use cases benefit when minimizing complexity and hardware footprints with converged networks. 

    In this environment, the following connectivity modules are configured in each PowerStore node (node A and node B (see Figure 1):

    • Two 25 Gb/second Ethernet modules for NAS and file (SMB), using the embedded module
    • Two 25 Gb/second Ethernet modules for block storage (iSCSI), using I/O Module 1

    This configuration provides more than enough bandwidth for the block and file user data load. To isolate and allow traffic prioritization, VLANs are configured for each type of Ethernet traffic.
