VCF and VxBlock System 1000 Upgrade all required components based on the VCF Bill of Materials (BOM). Partial BOM upgrades are not supported. VCF uses VMware ESXi vendor-specific ISO images upgrades and are configured to use Cisco OEM supported drivers and VIBS. Go to VMware Docs and search for VMware Cloud Foundation Lifecycle Management for procedures on Upgrading ESXI with Custom ISO or Async Drivers. To download VCF bundles, configure VMware SDDC Manager and VMware vLCM to work with the My VMware account. Once configured, VMware vLCM automatically polls the VMware depot to identify available bundles. Download upgrade bundles To download VCF bundles, configure VMware SDDC Manager and VMware vLCM to work with the My VMware account. Once configured, VMware vLCM automatically polls the VMware depot to identify available bundles. When upgrade bundles are available, a message is displays on the VMware SDDC Manager dashboard and upgrade bundles display on the Bundle Management page. The Bundle Details column displays the workload domains to apply the bundle, and the Availability column displays status. If another bundle is to be applied first, the Availability column displays Future. The VMware SDDC Manager repository provides VMware ESXi ISO bundles with in-box drivers. These ESXi ISO are not used but must be downloaded. The RCM corresponds to each VCF BOM (for example, VCF 18.104.22.168, 22.214.171.124, and 126.96.36.199 RCMs). The Dell Technologies RCM for AMP Central VSAN or the VxBlock System with VCF provides a Dell EMC custom ISO with the appropriate drivers and VIBs. Manually upload the management and VI workload domain using separate ISOs to VMware SDDC Manager. Go to the Download Center for VMware ESXi management domain and VI workload domain custom ISOs. Do not perform a VCF upgrade without a corresponding Dell Technologies RCM. VMware ESXi upgrades include drivers that may require a minimum Cisco UCSM or Cisco IMC BIOS version.
