Day 4 of VMworld was another day filled with announcements and information. Today, we are highlighting a few of the key messages related to vSAN.

1. vSAN 6.7U1There have been multiple announcements around the next release of vSAN (6.7U1). The first is VMware Update Manager (VUM) support for Firmware during vSAN upgrades (for now, this is for the Dell HBA330 only, but soon other controllers will follow). VUM will recognize the vendor type and validate compliance and update accordingly when/if needed. Second is TRIM/UNMAP support for shrinking VMDKs on vSAN. This will enhance/improve space efficiency. (Requires VM to be power cycled) Up next is the Cluster Quickstart Wizard. This is a single wizard allowing users to select the required services, add the hosts and configure the cluster (including HA, DRS, vSAN and the network components). Below are a few smaller updates with this new release:
   • Historical Capacity Reporting and other enhancements for vSAN with vROPS
   • Maintenance mode pre-checks
   • Nested fault domains on standard clusters (via special request only)
2. VMware on AWS EnhancementsAnother exciting development was around functionality introduced for vSAN in VMware Cloud on AWS. The first announcement was the ability to use Elastic Block Storage (EBS volumes) for vSAN, meaning that VMware Cloud on AWS users can now extend a cluster with capacity delivered through EBS. The big advantage here, of course, is that customers can now scale storage independent of compute. The second announcement is the availability of vSAN Encryption in VMware Cloud on AWS. Customers now have the ability to use vSAN encryption with keys stored in AWS Key Management Service (KMS).
3. VMware vSAN BetaLast but not least, there was a vSAN Beta announcement with several different components listed below. Stay tuned for more on this release.
   • vSAN Data Protection
   • vSAN File Services
   • Cloud Native Storage
