Download VMware ESXi / vCenter 7.0 Update 2

Virtualization has gained a prominent place in recent decades. Well-known names include Xen and VMware. VMware’s complete platform is called vSphere and consists of several components, such as vCenter Server, which can manage a complete virtual environment, and of course the hypervisor ESXi, on which virtual machines can do their work. A few days ago, 7.0 Update 2 of both vCenter Server and ESXi was released with the following release notes:

What’s New

• ESXi 7.0 Update 2 supports vSphere Quick Boot on the following servers:
  • Dell Inc.
    • PowerEdge M830
    • PowerEdge R830
  • HPE
    • ProLiant XL675d Gen10 Plus
  • Lenovo
    • ThinkSystem SR 635
    • ThinkSystem SR 655
• Some ESXi configuration files become read-only: As of ESXi 7.0 Update 2, configuration formerly stored in the files /etc/keymap, /etc/vmware/welcome, /etc/sfcb/sfcb.cfg, /etc/vmware/snmp.xml, /etc/vmware/logfilters , /etc/vmsyslog.conf, and /etc/vmsyslog.conf.d/*.conf files, now resides in the ConfigStore database. You can modify this configuration only by using ESXCLI commands, and not by editing files. For more information, see VMware knowledge base articles 82637 and 82638.
• VMware vSphere Virtual Volumes statistics for better debugging: With ESXi 7.0 Update 2, you can track performance statistics for vSphere Virtual Volumes to quickly identify issues such as latency in third-party VASA provider responses. By using a set of commands, you can get statistics for all VASA providers in your system, or for a specified namespace or entity in the given namespace, or enable statistics tracking for the complete namespace. For more information, see Collecting Statistical Information for vVols.
• NVIDIA Ampere architecture support: vSphere 7.0 Update 2 adds support for the NVIDIA Ampere architecture that enables you to perform high end AI/ML training, and ML inference workloads, by using the accelerated capacity of the A100 GPU. In addition, vSphere 7.0 Update 2 improves GPU sharing and utilization by supporting the Multi-Instance GPU (MIG) technology. With vSphere 7.0 Update 2, you also see enhanced performance of device-to-device communication, building on the existing NVIDIA GPUDirect functionality, by enabling Address Translation Services (ATS) and Access Control Services (ACS) at the PCIe bus layer in the ESXi kernel.
• Support for Mellanox ConnectX-6 200G NICs: ESXi 7.0 Update 2 supports Mellanox Technologies MT28908 Family (ConnectX-6) and Mellanox Technologies MT2892 Family (ConnectX-6 Dx) 200G NICs.
• Performance improvements for AMD Zen CPUs: With ESXi 7.0 Update 2, out-of-the-box optimizations can increase AMD Zen CPU performance by up to 30% in various benchmarks. The updated ESXi scheduler takes full advantage of the AMD NUMA architecture to make the most appropriate placement decisions for virtual machines and containers. AMD Zen CPU optimizations allow a higher number of VMs or container deployments with better performance.
• Reduced compute and I/O latency, and jitter for latency sensitive workloads: Latency sensitive workloads, such as in financial and telecom applications, can see significant performance benefit from I/O latency and jitter optimizations in ESXi 7.0 Update 2. The optimizations reduce interference and jitter sources to provide a consistent runtime environment. With ESXi 7.0 Update 2, you can also see higher speed in interrupt delivery for passthrough devices.
• Confidential vSphere Pods on a Supervisor Cluster in vSphere with Tanzu: Starting with vSphere 7.0 Update 2, you can run confidential vSphere Pods, keeping guest OS memory encrypted and protected against access from the hypervisor, on a Supervisor Cluster in vSphere with Tanzu. You can configure confidential vSphere Pods by adding Secure Encrypted Virtualization-Encrypted State (SEV-ES) as an additional security enhancement. For more information, see Deploy a Confidential vSphere Pod.
• vSphere Lifecycle Manager fast upgrades: Starting with vSphere 7.0 Update 2, you can significantly reduce upgrade time and system downtime, and minimize system boot time, by suspending virtual machines to memory and using the Quick Boot functionality. You can configure vSphere Lifecycle Manager to suspend virtual machines to memory instead of migrating them, powering them off, or suspending them to disk when you update an ESXi host. For more information, see Configuring vSphere Lifecycle Manager for Fast Upgrades.
• Encrypted Fault Tolerance log traffic: Starting with vSphere 7.0 Update 2, you can encrypt Fault Tolerance log traffic to get enhanced security. vSphere Fault Tolerance performs frequent checks between the primary and secondary VMs to enable quick resumption from the last successful checkpoint. The checkpoint contains the VM state that has been modified since the previous checkpoint. Encrypting the log traffic prevents malicious access or network attacks.

Product Support Notices

• Removal of SHA1 from Secure Shell (SSH): In vSphere 7.0 Update 2, the SHA-1 cryptographic hashing algorithm is removed from the SSHD default configuration.
• Intent to deprecate SHA-1: The SHA-1 cryptographic hashing algorithm will be deprecated in a future release of vSphere. SHA-1 and the already-deprecated MD5 have known weaknesses, and practical attacks against them have been demonstrated.
• Standard formats of log files and syslog transmissions: In a future major ESXi release, VMware plans to standardize the formats of all ESXi log files and syslog transmissions. This standardization affects the metadata associated with each log file line or syslog transmission. For example, the time stamp, programmatic source identifier, message severity, and operation identifier data. For more information, visit

Resolved Issues

• Installation, Upgrade, and Migration Issues: Upgrades to ESXi 7.x from 6.5.x and 6.7.0 by using ESXCLI might fail due to a space limitation
• Storage Issues: After recovering from APD or PDL conditions, VMFS datastore with enabled support for clustered virtual disks might remain inaccessible
• Auto Deploy Issues: PR 2710383: If you deploy an ESXi host by using the vSphere Auto Deploy stateful install, ESXi configurations migrated to the ConfigStore database are lost during upgrade
• Networking Issues: PR 2696435: You cannot use virtual guest tagging (VGT) by default in an SR-IOV environment
