What’s in the Release Notes
These release notes introduce you to new features in VMware vSAN 8.0 Update 2 and provide information about known issues.

What’s New
vSAN 8.0 Update 2 introduces the following new features and enhancements:

Disaggregated Storage

Enhanced topologies for disaggregation with vSAN Express Storage Architecture bring feature parity for vSAN OSA and vSAN ESA.

vSAN ESA support for stretched clusters in disaggregated topology. vSAN ESA supports disaggregation when using vSAN stretched clusters. In addition to supporting several stretched cluster configurations, vSAN also optimizes the network paths for certain topologies to improve the performance capabilities of stretched cluster configurations.

Support of disaggregation across clusters using multiple vCenter Servers. vSAN 8.0 Update 2 supports disaggregation across environments using multiple vCenter Servers when using vSAN ESA. This enables vSphere or vSAN clusters managed by one vCenter Server to use the storage resources of a vSAN cluster managed by a different vCenter Server..

vSAN ESA Adaptive Write path for disaggregated storage. Disaggregated deployments get the performance benefits of a new adaptive write path previously introduced in vSAN 8.0 Update 1 for standard ESA based deployments. VMs running on a vSphere or vSAN cluster that consume storage from another vSAN ESA cluster can take advantage of this capability. Adaptive write path technology in a disaggregated environment helps your VMs achieve higher throughput and lower latency, and do so automatically in real time, without any interaction by the administrator.

Core Platform Enhancements

Integrated File Services for Cloud Native and traditional workloads. vSAN 8.0 Update 2 supports vSAN File Service on vSAN Express Storage Architecture. File service clients can benefit from performance and efficiency enhancements provided by vSAN ESA.

Adaptive Write Path optimizations in vSAN ESA. vSAN ESA introduces an adaptive write path that helps the cluster ingest and process data more quickly. This optimization improves performance for workloads driving high I/O to single object (VMDK), and also improves aggregate cluster performance.

Increased number of VM’s per host in vSAN ESA clusters (up to 500/host). vSAN 8.0 Update 2 supports up to 500 VMs per host VM on vSAN ESA clusters, provided the underlying hardware infrastructure can support it. Now you can leverage NVMe-based high performance hardware platforms optimized for the latest generation of CPUs with high core densities, and consolidate more VMs per host.

New ReadyNode profile and support for read-intensive devices for vSAN ESA. vSAN ESA announces the availability of new ReadyNode profiles designed for small data centers and edge environments with lower overall hardware requirements on a per-node basis. This release also introduces support for read-intensive storage devices.

vSAN ESA support for encryption deep rekey. vSAN clusters using data-at-rest encryption have the ability to perform a deep rekey operation. A deep rekey decrypts the data that has been encrypted and stored on a vSAN cluster using the old encryption key, and re-encrypts the data using newly issued encryption keys prior to storing it on the vSAN cluster.

Enriched Operations

vSAN ESA prescriptive disk claim. vSAN ESA includes a prescriptive disk claim process that further simplifies management of storage devices in each host in a vSAN cluster. This feature provides consistency to the disk claiming process during initial deployment and cluster expansion.

Capacity reporting enhancements. Overhead breakdown in vSAN ESA space reporting displays both the ESA object overhead and the original file system overhead.

Auto-Policy management improvements in vSAN ESA. Enhanced auto-policy management feature determines if the default storage policy needs to be adjusted when a user adds or removes a host from a cluster. If vSAN identifies a need to change the default storage policy, it triggers a health check warning. You can make the change with a simple click at which time vSAN reconfigures the cluster with the new policy.

Skyline Health remediation enhancements. vSAN Skyline Health helps you reduce resolution times by providing deployment-specific guidance along with more prescriptive guidance on how to resolve issues.

Key expiration for clusters with data-at-rest encryption. vSAN 8.0 Update 2 supports the use of KMS servers with a key expiration attribute used for assigning an expiration date to a Key Encryption Key (KEK).

I/O top contributors enhancements. vSAN Performance Service has improved the process to find performance hot spots over a customizable time period to help you diagnose performance issues while using multiple types of sources for analysis (VMs, host disks, and so on).

I/O Trip Analyzer supported on two node clusters and stretched clusters. vSAN 8.0 Update 2 has enhanced the I/O Trip Analyzer to report on workloads in a vSAN stretched cluster. Now you can determine where the primary source of latency is occurring in a vSAN stretched cluster, as well as latencies in other parts of the stack that can contribute to the overall latency experienced by the VM.

Easier configuration for two node clusters and stretched clusters. Several new features to help management of two node and stretched cluster deployments.

Witness host traffic configured in the vSphere Client.​

Support for medium sized witness host appliance in vSAN ESA.

Support in vLCM to manage lifecycle of shared witness host appliance types.

Cloud Native Storage

CSI snapshot support for TKG service. Cloud Native Storage introduces CSI snapshot support for TKG Service, enabling K8s users and backup vendors to take persistent volume snapshots on TKGS.

Data mobility of Cloud Native persistent volumes across datastores. This release introduces built-in migration of persistent volumes across datastores in
