VMware vSphere Predictive DRS

It’s no secret that this is a feature that I’m very excited about.  This feature although very useful on it’s own is going to open up the door for many new exciting capabilities with out VMware products in the future.

Predictive DRS

Resource contention is one of the most critical issues in any virtualized environment.  When contention occurs, applications slow down and your users are affected.  Up until now two different methodologies have been employed to mitigate the risk of contention, with varied results.  But now I want to introduce you to the new “game changing” method available from VMware: Predictive DRS!  But first a bit of a history lesson on the original two methods.

REACTIVE METHOD

The first of these is the Reactive Method which focuses on resolving unexpected resource demand.  The most widely used example of a reactive solution is VMware’s Distributed Resource Scheduler, or DRS. As the day progresses, workloads may need more resources, which can lead to contention on the host.  The reactive method moves VMs around to ensure all workloads get the resources they need and applications remain healthy. Note this method needs only a minimal amount of VMs to be moved in order to be effective, which means minimal overhead. The reactive method only moves VMs when contention approaches, so it’s possible (however remote) for users to feel some effects of the contention before it’s resolved.

Learn more about the other methods available with predictive DRS in the original article on VMware Cloud Management blog site.

 

VMware vSphere 6.5 and NSX, customer running NSX don’t upgrade to vSphere 6.5 just yet

Loving the list of new features in vSPjere 6.5?  Thinking about digging in and upgrading your lab or other environment?  Well if that environment is running NSX you will want to wait just a little longer.  vSphere 6.5 is currently not compatible with NSX including 6.1.x and 6.2.x.  See KB 2147548 for more details.

Now I have nothing official to say on this, but as you might expect I’m sure this will be resolved once a new version of NSX drops.  We have all been there before where we just got the GA announcement of vSphere and rushed to upgrade our virtual labs and oh wait crap, NSX is not supported.  This is nothing new this has been the case for last few releases if you recall.  You may remember reading this article about vSPhere 6.

  • Content Pack Features
    • Users can now subscribe to content pack alerts that allow automated updates inline with the associated content pack.
  • Changed Behavior
    • New Agent installations have SSL enabled by default. Previously, Agent installs defaulted to SSL off. Upgrading does not affect current SSL settings.
    • New event forwarder destinations now default to verifying SSL certificates. Previously, SSL certificates were not verified by default. Upgrading does not affect current settings.
    • vRealize Log Insight for vCenter now allows you to change SSL settings.
    • For content pack alerts instantiated in 4.0, content pack updates now automatically update alert definitions. If needed, you can preserve customizations by exporting them and then importing them back into the user profile after the update is applied.

Release Announcement – VMware vSphere 6.5 has been released

This is super exciting news.  There are two features in particular that I am very excited to see in vSphere 6.5.

vSphere Integrated Containers – Run docker containers natively (well almost) on top of vSphere.  VIC as it has been coined allows you to use the Docker API to spin up Docker containers inside a vSphere VM container.  The vSphere VM container runs a super small version of PhotonOS that allows the container to run inside the VM container.  This now allows you to run Docker containers with all the benefits of vSphere VM’s with the exception of NSX at the moment.  However your containersa can take advantage of another new much anticipated feature.

vSphere Predictive DRS – Predictive DRS is a game-changing new technology that leverages self-learning and predictive analytics provided by vRealize Operations.  It learns your environment and based on usage patterns, preemptively rebalances your workloads in advance of upcoming demands and spikes.  This ensures your applications remain performant and your workloads get all the resources they need.

These aren’t the only exciting new features, but they are certainly two of my favorites.  Among the other new features are:

  • Scale Enhancements – New configuration maximums to support even the largest app environments
  • VMware vCenter Server® Appliance – The single control center and core building block for vSphere
  • vCenter Server® High Availability – Native vCenter Server high availability solution
  • vCenter Server Backup and Restore – Native vCenter Server Backup and Restore
  • vCenter Server Appliance Tool – Single step migration and upgrade of existing vCenter Server to vCenter Server Appliance
  • REST APIs – Simple, modern developer-friendly APIs
  • vSphere Client – HTML5-based GUI that ensures fast performance and cross-platform compatibility
  • Security-at-Scale – Policy-driven security that makes securing infrastructure operationally simple
  • Encryption – VM-level encryption protects unauthorized data access both at-rest and in-motion
  • Audit-quality logging – Enhanced logging that provides forensic information about user actions
  • Secure Boot – Protection for both the hypervisor and guest operating system by ensuring images have not been tampered with and preventing loading of unauthorized components
  • Cross-Cloud vMotion® –Live migrate workloads between VMware based clouds ( Handy feature for the new Amazon and VMware partnership)
  • Virtual Volumes™ Replication – Native array virtual volumes replication

Release Announcement – VMware vSphere Replication 6.5

GA Date:  November 15, 2016

What is vSphere Replication?

vSphere Replication is VMware’s proprietary hypervisor-based replication engine designed to protect running virtual machines from partial or complete site failures by replicating their VMDK disk files.  It provides simple and cost-efficient replication to a distant failover site or between local hosts within a single site.  Used standalone or in conjunction with Site Recovery Manager, it offers customers an alternative to traditional storage array-based replication technologies.  vSphere Replication is also the engine powering the vCloud Air Disaster Recovery service and the vCloud Availability for vCloud Director offering targeted for vCAN Service Providers.

What’s New in this release:

  • 5-minute Recovery Point Objective (RPO) support for additional data store types. This version of vSphere Replication extends support for the 5 minute RPO setting to the following new data stores: VMFS 5, VMFS 6, NFS 4.1, NFS 3, VVOL and VSAN 6.5. This allows customers to replicate virtual machine workloads with an RPO setting as low as 5-minutes between these various data store options.
  • Spanish locale for the product user interface and documentation. This version of vSphere Replication adds support for Spanish language localization of the UI and delivers product documentation in Spanish.
  • Integration with VMware Analytics Cloud (VAC).  vSphere Replication is now participating in the VMware Customer Experience Improvement Program (CEIP).
