New features in vSphere 7

vSphere Lifecycle Manager

Next-Gen Infrastructure Image Management Manage infrastructure images to patch, update or upgrade ESXi clusters using the desired state model.

the new tool called vLCM (vCenter vSphere LifeCycle Manager) to support upgrading vsphere environment.using this tool you can patch, update or upgrade ESXi servers at scale with RESTful APIs to automate lifecycle management and use a desired state image.
 

Hardware management
  •     Management of host firmware from within vSphere
  •     Works in conjunction with vendor management tools like
  •     Dell OpenManage and HPE OneView
  •     VCG/HCL checks and Recommendation Engine. Remove the risk of unsupported drivers/firmware!
  •     Full GUI and REST API available

vCenter Server Profiles 

Desired state configuration management capabilities for vCenter Server. It helps the user to define/validate/apply configuration for multiple vCenter Servers

vSphere 7 VMware releases a new feature called “vCenter Server Profiles. With this new feature, you can create a consistent configuration file that can be used across multiple vCenters. This configuration profile can be

This capability is based on just the REST API. There is no UI for this.  You capture the state of an existing vCenter Server by exporting the config in JSON format.

vCenter Server Update Planner 

Manage the compatibility & interoperability for vCenter Server for upgrade scenarios. We will allow users to generate the interoperability & pre-checks report, which will help them plan for upgrades.


Content Library

Added administrative control and versioning support. Provides simple and effective centralized management for virtual machine templates, virtual appliances, ISO images, and scripts.

The vCenter Server Content Library coming with a new process called check-in and check-out option to use revert templates to previous versions. Also include a new option to change the transfer settings for frequencies of Auto-Sync option.


VMotion 

vMotion The recent enhancements in vMotion logic provides non-disruptive operations, irrespective of the size of VMs, specifically for large and mission-critical workloads

With the increase in workload resource consumption and the growing of resource allocations for workloads, changes was necessary in vMotion. The challenge today is the performance impact we see during vMotion for stun times on very large VMs.

VMware refactored vMotion to solve these challenges and brining back vMotion capabilities for large workloads like SAP HANA or Oracle.

  •  When vMotion is initiated, Page Tracers are installed.  This is done on all the vCPU entitled to that specific virtual machine that is to be alive migrated.
  • During a vMotion, all changed memory pages are tracked by using a page tracer. 
  • Changed (or dirtied) memory pages are copied to the destination ESXi again.
 
 VM Hardware v17
 
Virtual Watchdog Timer 
  • Without a watchdog timer, guest OSes & applications don’t have a standard way to know that they crashed.    
  • A watchdog timer helps by resetting the VM if the guest OS is no longer responding.
  • This is especially important for clustered applications, like databases and filesystems.
 I hope this has been informative and thank you for reading!
