New Capabilities in vSAN 6.7 Update 3

New Capabilities in vSAN 6.7 Update 3

    • Intelligent Operations
      • Get enhanced estimates of when re-builds will be complete, as well as a near-continuous refresh of the estimate. Admins can assign high-priority objects to be re-built first and receive an ETA for every object in the queue. The information can also be filtered for easy searching.
      • For upgrades that require a full data evacuation, vSAN performs a simulation to estimate success or failure so that admins can have more confidence in the upgrade process.
      • In 6.7 Update 1, vSAN established intelligent guardrails, alerting you to data availability impacts when putting a host in maintenance mode. With Update 3, we’ve expanded your ability to test the impact of maintenance mode with a new UI for more detailed checks, as well as a customizable UI for testing.
      • vSAN now handles difficult resync operations with ease. In severely capacity-strained scenarios, vSAN will take steps to mitigate resync impacts by rebalancing capacity as needed. If an issue does occur, new health checks surface alerts and proactively guide admins through a graceful recovery workflow to get the cluster back up and running quickly.
    • Proactive Rebalancing
      Admins can now enable vSAN to proactively rebalance capacity distributed across the cluster, which aids in consistent performance for workloads. Set a policy for when rebalancing needs to occur and vSAN will actively monitor and remediate the cluster as necessary.


    • Smart Policy Implementation
      One of the most-loved benefits of vSAN is the ability to change policies on the fly. For instance, if you need to update the fault tolerance for a particular VM or VMDK, it takes only a few clicks to update the policy, and then the software implements, monitors, and remediates it. Policy implementation is now more thoughtful, with availability in mind. In the event of large policy changes, vSAN will minimize resources used during implementation so as not to impact ongoing operations.


    • Increased Visibility for Storage Consumption
      View raw vs. usable capacity, see how containers are consuming storage, and get alerts as data is consumed by VMs and containers.


    • Workflow-based Proactive Support Activation
      Easily enable and configure Support Insight in several workflows – QuickStart, vSAN Services, online health checks – as well as on a new Customer Experience Improvement Program (CEIP) page.


  • Enhanced Performance
    Higher throughput and more consistent performance using all-flash clusters, as well as faster resyncs, improves SLAs. Update 3 enables more consistent performance with small I/O writes, increased throughput of sequential I/O writes when dedup and compression is enabled, and faster resyncs due to increased task parallelization.
