Hardware, software, and license requirements

This section explains the hardware, software, and license requirements for upgrading to VMware vSphere 6.7.

Before upgrading a Converged System to VMware vSphere 6.7, review the following:

  • For the upgrade to VMware vCenter Server Appliance (vCSA) components, one temporary IP address is required. If the Platform Services Controller (PSC) is migrating from embedded to external, it requires two more permanent IP addresses. The temporary IP address must be on the same subnet as the VMware vCenter Server and accessible by the current VMware vCenter Server environment. This temporary IP address is required to migrate configuration and services data from:
    • VMware vCenter Server 6.0 or 6.5 PSC
    • VMware vCenter Server 6.0 for Windows
    • vCSA 6.0 or 6.5 to vCSA 6.7
  • Vblock Systems must migrate from an environment using Cisco Nexus 1000V virtual switch to an environment using VMware VDS. Contact Customer Support to migrate from the Cisco Nexus 1000V to VMware VDS.
  • For compute Cisco UCS B- and C-Series Servers, Dell EMC recommends a boot LUN size of 15 GB to facilitate VMware vSphere ESXi core dumps. See the Administration Guide associated with your Converged System to extend the size of the LUN from 10 GB – 15 GB.
  • IPv6 is not supported with VMware vSphere ESXi 6.7 on AMP-VX with vSAN and vSphere HA enabled.

    For VMware vSphere 6.7, the following servers are supported:

    • Standalone Cisco IMC-managed Cisco UCS C2xx M4 rack servers or higher
    • Cisco UCSM-managed Cisco UCS C2xx M3 rack and blade servers or higher

    For VMware vSphere 6.7 U3 only, standalone Cisco IMC-managed Cisco UCS C2xx M3 rack servers or higher are supported.

    See the VMware Compatibility Guide for more information.

  • Verify that the firmware version of the Cisco UCS B and C-Series servers in your Converged System is compatible with VMware vSphere 6.7. See the Converged System Release Certification Matrix and the Converged System Release Notes for the release to which you are upgrading for more information.
  • When upgrading to vSphere 6.7, evaluate the active/consumed memory and ensure to have enough physical memory on the AMP hosts.
  • Ensure that you review and comply with the license requirements as specified in the Release Notes for the release of the software on your Converged System.
  • Verify that the new vCSA and PSC meet the hardware requirements, including the additional required disk storage and memory. See the System Requirements section of the VMware vSphere Upgrade documentation: https://docs.vmware.com/en/VMware-vSphere/6.7/com.vmware.vcenter.upgrade.doc/GUID-752FCA83-1A9B-499E-9C65-D5625351C0B5.html
  • Verify that all components are in a ready state and free from errors and alarms.
  • Verify that Vision Intelligent Operations is at version 3.6.2 or higher. If you must upgrade, see the appropriate Vision Intelligent Operations Upgrade Guide or Dell EMC VxBlock™ Central Upgrade Guide.
  • If the environment has VMware NSX, upgrade to VMware NSX 6.4.x before upgrading VMware vCenter Server to 6.5. VMware NSX 6.2.x is incompatible with VMware vCenter Server 6.5 but is compatible with NSX 6.4. See the Dell EMC Converged Systems Upgrade Guide from VMware NSX 6.2.x to VMware NSX 6.4.x for VMware NSX upgrade procedures. See the VMware compatibility Matrix for compatibility between NSX and vSphere: http://partnerweb.vmware.com/comp_guide2/sim/interop_matrix.php#interop&2=2332,2136&93=2349,2528,2436
NOTE: On VMware vSphere 6.7 deployments, disable the Host TPM attestation alarm definition to suppress attestation errors when TPM modules are installed but not used.
The recommendation is to increase Max LUN value for Fibre Channel Adapter policy to 1024. To increase the MAX LUN:
  1. In UCSM, select SAN > Policies > root > Fibre Channel Adapter Policies.
  2. Select the adapter policy of the ESXi hosts.
  3. Select Options.
  4. Set the MAX LUN per Target to 1024.
    NOTE: Updating the MAX LUN may cause traffic disruption for all hosts, so update the MAX LUN before upgrading to ESXi 6.7.
  5. After upgrading to ESXi 6.7, log in to vCenter using the HTML5 client.
  6. Select Host > Manage > Advanced System Settings > Edit.
  7. In Filter type, set the disk.maxLUN to 1024 for each host.
