What's in the Release Notes

This release notes cover the following topics:

What's New

Carrier-Grade Resilient Networking

VMware NSX-T Data Center 3.1 introduces the following new features for virtualized networking and security for private, public, and multi-clouds.

  • Cloud-scale Networking: Federation enhancements and Enhanced Multicast capabilities
  • Intrinsic Security: Distributed IPS and FQDN-based Enhancements
  • Lifecycle and monitoring: NSX-T support with vSphere Lifecycle Manager (vLCM), simplified installation, enhanced monitoring, search and filtering.

For more information about these features, see the VMware NSX-T Data Center 3.1 Release Notes.

Multi-Tenancy Management

VMware Cloud Director 10.2 introduces the following new features and enhancements:

  • NSX-T Advanced Functional Parity: NSX Advanced Load Balancer (Avi), Distributed Firewall, VRF-lite, Cross VDC networking, IPv6, Dual stack (IPv4/IPv6) on the same network, SLAAC, DHCPv6, CVDS (vSphere 7.0/NSX-T 3.0), and L2VPN – API only.
  • VMware Cloud Director Virtual Appliance Enhancements: Validation of user inputs during the initial deployment. Simplified cell restore with streamlined standby cell creation.
  • Storage Enhancements: Disk-level IOPS control for providers and tenants; Shared disks
  • UI Enhancements: Quick Search, Advisories, and Certificate Management

For more information about these features and enhancements, see the VMware Cloud Director 10.2 Release Notes.

Workload Compute & Storage Performance

VMware vSphere 7.0 Update 1 introduces the following new features and enhancements:

  • Enhanced vSphere Lifecycle Manager hardware compatibility pre-checks for vSAN environments
  • Increased number of vSphere Lifecycle Manager concurrent operations on clusters
  • vSphere Lifecycle Manager support for coordinated updates between availability zones
  • Virtual hardware version 18
  • Increased resource maximums for virtual machines and performance enhancements

For more information about these features and enhancements, see the VMware vSphere 7.0 Update 1 Release Notes.

VMware vSAN 7.0 Update 1 introduces the following new features and enhancements:

  • HCI Mesh: HCI Mesh is a software-based approach for disaggregation of compute and storage resources in vSAN. It brings together multiple independent vSAN clusters by enabling cross-cluster utilization of remote datastore capacity within vCenter Server. HCI Mesh enables efficient utilization and consumption of data center resources and provides simple storage management at scale.
  • vSAN File Service Enhancements: Native vSAN File Service includes support for SMB file shares. Support for Microsoft Active Directory, Kerberos authentication, and scalability improvements also are available.
  • Compression-only vSAN: You can enable compression independent of deduplication, thereby providing the storage efficiency option for workloads that cannot leverage deduplication. With compression-only vSAN, a failed capacity device does not impact the entire disk group.
  • vSAN Data-in-Transit Encryption: Enables secure over-the-wire encryption of data traffic between nodes in a vSAN cluster. vSAN data-in-transit encryption is a cluster-wide feature. It can be enabled independently or along with the vSAN data-at-rest encryption. Traffic encryption uses the same FIPS-2 validated cryptographic module as the existing encryption features. It does not require a KMS server.
  • Enhanced Data Durability During Maintenance Mode: Protects the integrity of data when a host is in maintenance mode with the Ensure Accessibility option. All incremental writes to the host in maintenance are now redirected to another host, if it is available. This feature benefits VMs configured with PFTT=1 and also provides an alternative to PFTT=2 to ensure data integrity during maintenance operations.

For more information about these features, see the VMware vSAN 7.0 Update 1 Release Notes.

Resolved Issues

  • Cloud Director UI Gets Stuck When Creating vApp Using Extra Configuration Parameter in OVA/OVF Template

    This issue is fixed in VMware Cloud Director 10.2.

  • Objects of Cloud Director Provider UI are Not Visible When Using Invalid Certificates for Configuring Multisite Cloud Director Association

    This issue is fixed in VMware Cloud Director 10.2.

  • TraceFlow From One VM to Another VM is Not Working in Guest Inter-VLAN Routing in NSX-T Data Center

    This issue is fixed in VMware NSX-T Data Center 3.1.

  • Unable to Power ON the Cloud Director VMs That are Connected with SR-IOV Network  

    This issue is fixed in VMware Cloud Director 10.2.

  • Dynamically Changing the Lcore Assignment Value from the Transport Node Profile May Cause ESXi Server to PSOD

    This issue is fixed in VMware NSX-T Data Center 3.1.2.

Known Issues

  • Cannot Merge Provider VDCs Backed by NSX-T Data Center

    When you merge two Provider Virtual Data Centers (VDCs) that are backed by NSX-T Data Center, the following error occurs:

    Cannot merge Provider VDCs. Found NSX-T backed Provider VDC

    Workaround: None

  • IPv4 North-South Communication Breaks When Adding IPv6 NIC Followed by IPv4

    If you add IPv6 NIC first and IPv4 NIC later to a virtual machine using the VMware Cloud Director UI, the IPv4 north-south communication breaks.

    Workaround: Always add IPv4 NIC first followed by IPv6 NIC to the VM.

  • Network Creation Failed During the NSX-T Node Failover

    The creation of a new network fails in the VMware Cloud Director UI when the NSX-T node failover is in progress.

    Workaround: Wait until the NSX-T node failover completes and then create the network from the Cloud Director UI.

  • Unable to Launch VM Web Console Using the Launch Web Console Option in VMware Cloud Director

    The VM Web Console is not launching when using the Launch Web Console option in VMware Cloud Director.

    Workaround: Access the VM Console using the Launch Remote Console option from the VMware Cloud Director UI or from the corresponding vCenter Server.

  • Bootstrap Patch Termination Error Occurs When Upgrading vRealize Orchestrator from Version 8.1 to 8.2

    When you upgrade vRealize Orchestrator from version 8.1 to 8.2, the following error occurs:

    Update bootstrap patch was terminated.

    Workaround: Deploy vRealize Orchestrator 8.2 using the Greenfield method instead of upgrade and import the vRealize Orchestrator objects such as workflows and packages from vRealize Orchestrator 8.1. For more information, see Managing Packages in the vRealize Orchestrator documentation.  

  • Tunnels on the Edge and Host Nodes Go Down in ESXi After Modifying the Lcore Assignments to the NUMA Nodes

    When modifying the number of lcores assigned to the NUMA nodes in the transport node profile, the tunnels go down on the respective edge and host nodes.

    Workaround: Follow the instructions in the KB article 83737.
