3 Getting started Topics: • Network configuration for PowerStore X model appliances • Hypervisor configuration for PowerStore X model appliances • Adding an external ESXi host to a PowerStore X model ESXi cluster in vCenter Server • Using an external ESXi host with a PowerStore cluster Network configuration for PowerStore X model appliances Plan your network configuration before setting up your PowerStore X model appliance. The PowerStore X model appliance has some specific requirements and considerations that do not apply to PowerStore T model clusters. For detailed information about network configuration with PowerStore X model appliances, see the PowerStore Network Planning Guide. The document includes: ● Planning and preparation information ● Configuration recommendations and best practices ● Network configuration, VLAN, and IP address requirements ● Switch configuration and cabling procedures ● Network configuration validation instructions NOTE: If the configuration is modified, there are some consequences and limitations that impact HA. Virtual network configuration Networking on a PowerStore X model appliance is controlled by ESXi, which uses a virtual switch to share network devices with the controller VM. As a part of cluster creation, a vSphere Distributed Switch (vDS) is set up to manage network traffic. The vDS enables features such as advanced QoS priority configuration with Network I/O Control (NIOC). In general, this configuration does not impact the management of a PowerStore X model appliance. However, there are some considerations for HA if the default configuration is modified. NOTE: Do not upgrade a vDS even if there are upgrade notifications or options available in vCenter Server. User VM Networking Before deploying user VMs on the internal ESXi hosts, create a distributed port group in vCenter Server for your external network. When you deploy user VMs, use that port group for external network connectivity. NTP server requirements To prevent issues with lag time between vCenter Server and ESXi hosts when creating your cluster, ensure that they are using the same NTP server. Getting started 13
