VxRail Hardware Installation and Configuration

What this domain covers

This domain covers physical installation and the first configuration steps that make nodes discoverable: racking, power, cabling, iDRAC, BIOS/firmware baseline, and initial VxRail Manager access.

Core rules

  • Verify the shipment against the bill of materials and record service tags and MAC addresses before racking.
  • Install the rail kit and cable management arm. Maintain front-to-back airflow and do not block intake or exhaust.
  • Connect dual power supplies to separate PDUs or circuits. Confirm the site voltage and power budget for the model.
  • Cable iDRAC to the management switch. Cable data ports to the top-of-rack switches with redundant paths, for example port 1 to ToR A and port 2 to ToR B. Use the optics, DACs, and speeds listed in the support matrix.
  • Give iDRAC a static address, DNS, NTP, and known credentials. VxRail Manager uses iDRAC to discover and configure nodes, so unreachable iDRAC means an undiscoverable node.
  • Do not change factory BIOS or firmware settings unless directed by VxRail procedures. The factory baseline is part of the validated appliance.
  • Power on switches first, then nodes. Wait for initialization before opening the deployment wizard.
  • Access VxRail Manager at its factory management address or through the iDRAC console, then set the production management IP, DNS, NTP, and passwords in the initialization workflow.

Worked example

A four-node cluster with two ToR switches. Each node has two 25 GbE data ports. Connect port 1 to ToR A and port 2 to ToR B; connect iDRAC to the 1 GbE management switch; connect PSU 1 to PDU A and PSU 2 to PDU B. Reasoning: vSAN can survive a single ToR failure, and iDRAC remains reachable while data VLANs are being configured. If only one ToR exists, document the non-redundant design and confirm support before deployment.

Traps

  • Plugging both PSUs into the same PDU, which defeats redundancy.
  • Leaving iDRAC on DHCP and losing the address before discovery.
  • Cabling data ports into the management switch or using unsupported 1 GbE optics.
  • Changing BIOS settings that break the VxRail factory baseline.
  • Not recording serial numbers and MACs for later support cases.
