VMware vSAN 6.6

VMware vSAN 6.6 is the industry-leading software powering Hyper-Converged Infrastructure (HCI) solutions. vSAN is optimized for VMware vSphere virtual machines and natively integrated with vSphere . Since drives internal to the vSphere hosts are used to create a vSAN datastore, there is no dependency on expensive, difficult to manage, external shared storage.

vSAN already integration with vSphere and the VMware ecosystem makes it the ideal storage platform for business-critical applications, disaster recovery sites, remote office and branch office (ROBO) implementations, test and development environments, management clusters, security zones, and virtual desktop infrastructure (VDI). Today, customers of all industries and sizes trust vSAN to run their most important applications.

All-flash configurations provide the highest levels of performance with very low latencies for demanding business-critical applications. Space efficiency features such as inline deduplication and compression minimize capacity consumption, which reduces capital expenditures. Per-virtual machine (VM) storage policy-based management lowers operational expenditures by enabling administrators to manage performance, availability, and capacity consumption with ease and precision. This means no more LUN management.

Many deployment options are available for vSAN. These options range from single, 2-node clusters for small implementations to multiple clusters each with as many as 64 nodes—all centrally managed by vCenter Server. Stretched clusters can easily be configured to enable cross-site protection with no downtime for disaster avoidance and rapid, automated recovery from entire site failure.

vSAN 6.6, the sixth generation of vSAN, is designed to help customers modernize their infrastructure by addressing three key IT needs: higher security, lower costs, and faster performance. For example, vSAN 6.6 further lowers total cost of ownership by providing more resilient, economical stretched clusters that are easy to deploy and maintain.

New Features

  • vSAN Encryption
  • Stretched Cluster with Local Site Protection
  • Removal of Multicast Support Unicast Networking (Cloud-friendly Networking with Unicast)
  • ESXi Host Client (HTML-5) management and monitoring functionality
  • Enhanced rebalancing
  • Enhanced repairs
  • Enhanced resync
  • Resync throttling
  • Maintenance Pre-Check
  • Stretched Cluster Witness Replacement UI
  • API enhancements
  • vSAN Easy Install
  • Enhanced Health Monitoring


The industry’s first native HCI encryption solution and a highly available control plane is delivered in vSAN 6.6 to help customers evolve without risk without sacrificing flash storage efficiencies. Operational costs are reduced with 1-click firmware and driver updates, as well as, proactive cloud-connected health checks for real-time support.

vSAN has been enhanced with up to 50% greater flash performance enabling customers to scale to tomorrow’s IT demands. vSAN storage services are integrated with the Photon Platform with full API management to support container technologies and take advantage of DevOps efficiency.

VMware vRealize Automation 7.3

vRealize Automation 7.3, the next iteration of VMware’s industry-leading cloud automation platform. While this is a an incremental “dot” release on the outside, it packs a punch in feature/functionality on the inside.



This release continues the trend of delivering awesome innovations, improved user experience and greater / deeper integration into the ecosystem its managing. Below is a summary of many of the new features and capabilities that are packed into vRA 7.3.

Enhanced API’s for Deploying, Upgrading and Migrating vRA - A new set of APIs to programmatically install, upgrade, and migrate the platform itself.

REST API Improvements – Customers can now deploy, configure, manage and consume vRealize Automation using a variety of programatic interfaces thanks to vRA’s ever-evolving REST API. VMware has released several new resources to help promote the use of these APIs, including the vRealize Automation Programing Guide, an updated Postman collection that includes several of the most commonly used API’s, and many additions to VMware{code}.

Audit Logging Framework – Tracking and analyzing user activity and security events is a critical enterprise requirement. vRA’s new Audit Logging Framework provides system-wide logging and auditing capabilities to gain additional visibility into your vRA environment. The VAMI-accessible Audit Log Integration option adds seamless integration with vRealize Log Insight and other syslog solutions, enables logging of essential services across IaaS and .net (windows) services, can be used to audit workflow subscriptions, IaaS services and more. The new service can be enabled in the VAMI or via API.

Integrated Health Service – The Health Service (vRPT) has now been integrated into vRealize Automation admin interface.

Parameterized Blueprints – This new feature leverages Size and Image policies to create consistent sizing policies (e.g. Small, Medium, Large, etc) intended to reduce blueprint sprawl.

Intelligent Workload Placement (WLP) – vRealize Automation can now use data in vRealize Operations (version 6.6) to provide analytics-based capacity management on vSphere. This includes the initial placement of a new instance, optimised according to performance goals, a ‘Balance’ policy used to maintain maximum headroom in case of spikes and a ‘Consolidate’ policy to leave space for large workloads.

Container Management – vRealize Automation now natively supports VMware Integrated Containers (VIC), allowing admins to add/manage VCH instances in vRA with a feature set similar traditional Docker hosts. vRA 7.3 also adds support for Docker volumes, allowing authors to create / attach volumes to containers and deploy volumes with container apps.

Config Automation Framework – vRA 7.3 adds native integration with Puppet, allowing actions such registering Puppet Master as an endpoint, drag-and-dropping Puppet nodes, dynamically querying Puppet Master, environment, and roles.


Azure Public Cloud Service Design Enhancements – A number of enhancements to the new Azure Endpoint like the ability to select, drag-and-drop software components on Azure machines in the blueprint designer, specify software properties on the blueprint designer and on the request form plus a set of pre-populated forms and dropdowns.


The control of NSX Endpoints is now extended to:

NSX on-demand NAT

  • Port forwarding rules can be configured at design time
  • Rules can be ordered
  • Rules can be added, removed, and reordered after you create them
NSX Security Group and Tag Management

  • Able to add existing NSX security groups or tags to a running application
  • Able to disassociate NSX security groups and tags from applications
High Availability Automated for NSX Edge Services

  • Edge high-availability mode in the blueprint provides high availability for all edge services to an application when it is deployed
  • Configurable per blueprint based on application availability needs
  • Use custom properties to determine high availability at request time
  • Adds high availability for load balancing, NAT, firewall, and so on
NSX Edge Size Selection

  • Able to specify deployment size for NSX Edge Services Gateway (ESG)
  • Configurable per-blueprint based on application needs or scale
  • Uses custom properties for size selection at request time

Beta Launch of docs.vmware.com

Today we are pleased to announce the beta launch of the docs.vmware.com site. This portal unifies the product documentation for all products, versions, and languages into a single site so you can find the information that you are looking for more quickly. VMware products offer a wide range of business solutions from desktop virtualization to support your hybrid cloud. We’ve heard your feedback that finding the right information can be difficult. Our search was out of date, the look and feel was not modern, the content was siloed, and the docs were not available on mobile devices. To address these problems, we decided to create a new site from scratch. The design of this site is meant to enable you to better filter content, find relevant answers, and create custom views of information that you can access on any device.

Find “Zombie” VMDK files


Today’s post is titled find “Zombie” vmdk files , I was recently working with a customer whose task was to find out multiple snapshots that are not displayed in the snapshot manager.

I tried a lot of time to skip this problem with consolidation of the Virtual Machine but in this scenario this solution seems that doesn’t work.
The reason behind this task was that many of the virtual Machine where snapshot remove from virtual machine and the customer was not sure on how to clear up the “Zombi” vmdk files.
In order to remove safely the snapshots that you see in your vCenter you have to dig a little from the esxi hosts , my choice ran it RVTools and export the vCenter report.
vHealth tab that showed all Zombie VMDK’s “zombie” VMs and also listed VM’s that where named differently from their corresponding folder.

VMware vSphere Remote Office Branch Office (ROBO) Editions

I was recently working with RFP for one of the Existing customer, this project is for remote site ESXi refresh. I found there is lot of inconsistency with ESXi version. All are running with Enterprise puls and found more than 70 + sites running with less than 15 VMs.

There are various ways that we can go ahead and refresh these ESXi hosts. I found another alternate solution with cost savings called vSphere ROBO ( Remote office Branch office ) licenses which is more cost effective and licenses are provided by VMWARE with virtual machine based pack.

VSphere ROBO is 25 VM’s pack , this is applicable for sites with maximum 25 VMs only and can also be shared between sites.

Customers can purchase these editions in packs of 25 Virtual Machines (VMs). A maximum of 1 pack can be deployed per remote site or branch office. Customers can choose to distribute a pack of 25 Virtual Machines across sites (e.g., 5 VMs in Site 1, 5 VM in Site 2 etc.).

Customers can centrally manage their ROBO hosts using VMWare vCenter server Standard or locally using vCenter server foundation.

VSphere ROBO is available in Standard and advanced version. Here, I will list the key features and components.

VMFS 6 vs VMFS 5 in vSphere

Recently VMware announced Vsphere 6.5 has introduced a new version of VMFS version 6 with lot of new enhancements. This topic will cover major difference between VMFS 5 and VMFS 6.


The upgrade process is slightly change, we can’t upgrade directly existing VMFS 5 volumes to VMFS 6. You have to plan and create new VMFS 6 datastores and migrate the existing VMFS 5 datastores VMs using storage vMotion. Once everything complete then ensure and deleting the VMFS 5 datastores.


Device Sector Formats and VMFS Versions

A sector is a subdivision of a track on a storage disk or device. Each sector stores a fixed amount of data. Traditional 512n storage devices have been using a native 512-bytes sector size. In addition, due to the increasing demand for larger capacities, the storage industry has introduced advanced formats, such as 512-byte emulation, or 512e. 512e is the advanced format in which the physical sector size is 4,096 bytes, but the logical sector size emulates 512-bytes sector size. Storage devices that use the 512e format can support legacy applications and guest operating systems.

When you set up a datastore on a 512e storage device, VMFS6 is selected by default. For 512n storage devices, the default option is VMFS5, but you can select VMFS6.


Automatic Space Reclamation

vSphere 6.5 has introduced automate the configuration of the VMFS UNMAP capability to check current setting or to Enable / Disable it. vSphere 6.5 APIs that have introduced which differ from the vsphere 5.x version.

How to Enable UNMAP setting

New vSphere API called UpdateVmfsUnmapPriority() which accepts the UUID of a VMFS 6 datastore as well as an unmapPriority property which can either be "low" which means it is enabled or "none" which means it is disabled.

VMFS UNMAP settings, there is a new property under the Datastore->Info->Vmfs object called UnmapPriority.
