Shockwave flash plugin crash issue in Chrome while using vSphere web client/vCD/vRA

Recently I came across a strange issue. While trying to login to web client interface, suddenly started getting below error when clicked Login to web client and also in the vCloud Director interface. I tried several times, however it was the same error. Login page gets loaded however once clicked login, you get the Shockwave flash crash issue.


Fortunately when Searched, I came across announcement from adobe for Adobe flash player 27 Beta release. You can get this plugin at below link for download.


After updating plugin on my MAC system issue was fixed as in screenshot below.



Currently this flash player update is in beta so check your policies for production use. It is available for major platforms like windows, Linux and MAC.

VMware updated certification roadmap

Note: VCA Exams are not mandatory to pursue any further certification as they are optional. However, vSphere Foundation exam is mandatory for all VCP certifications.

vSphere 6.5 and vNVMe controller

NVMe:

NVM Express (NVMe) or Non-Volatile Memory Host Controller Interface (NVMHCI) is a logical device interface specification for accessing non-volatile storage media attached via a PCI Express (PCIe) bus in real and virtual hardware.

The acronym NVM stands for non-volatile memory, commonly flash memory that comes in the form of solid-state drives (SSDs). NVM Express, as a logical device interface, has been designed from the ground up to capitalise on the low latency and internal parallelism of flash-based storage devices, mirroring the parallelism of contemporary CPUs, platforms and applications.

NVM Express allows host hardware and software to fully exploit the possible parallelism in modern SSDs. As a result, NVM Express reduces I/O overhead and brings various performance improvements in comparison to previous logical-device interfaces, including multiple, long command queues, and reduced latency. 

vSphere and NVMe:

NVM Express (NVMe) controller is available with ESXi 6.5 and Hardware Version 13. With Hardware Version 13, you can use NVMe, SATA, SCSI, and IDE controllers in a virtual machine.



Virtual NVMe (vNVMe):


Virtual NVMe Device has lower IO overhead and scalable IO for all-flash SAN/vSAN storages. Hardware NVMe SSDs has significant advantage over old SATA/SAS based Flash devices.
The main benefit of NVMe interface over SCSI is that it reduces the amount of overhead, and so consumes fewer CPU cycles. Also, there is a reduction of IO latency for your VMs. 

Each virtual machine can support 4 NVMe controllers and up to 15 devices per controller. 
Driver Architecture:




  • Native Model: Register/unregister driver and bring up device
  • VMKLinux Model: Deprecated
  • OS Libs: Provide OS related resource, such as heap, lock, interrupt.
  • Mgmt: Management interface to pass through admin command
  • SCSI Emulation Layer: The storage stack of ESXi is SCSI based, responsible for translating SCSI to NVMe command
  • NVMe Core: NVMe related stuff, such as queue construction, command issue, register read/write


Supported guest operating systems:

Not all operating systems are supported with vNVMe. Make sure that your OS is supported and also verify that the guest OS has a driver installed to use the NVMe controller.

  • Windows 7 and 2008 R2 (hot fix required: https://support.microsoft.com/en-us/kb/2990941
  • Windows 8.1, 2012 R2, 10, 2016 
  • RHEL, CentOS, NeoKylin 6.5 and later 
  • Oracle Linux 6.5 and later 
  • Ubuntu 13.10 and later 
  • SLE 11 SP4 and later 
  • Solaris 11.3 and later 
  • FreeBSD 10.1 and later 
  • Mac OS X 10.10.3 and later 
  • Debian 8.0 and later

GA for VRealize Operations Federation management pack

With vRealize Operations Federation Management Pack you can unify your multi-site vRealize Operations Manager deployment into a single pane of glass. You can instantiate a deployment of vRealize Operations Manager with the capability of receiving key metrics for specified objects from other vRealize Operations Manager deployments in your environment.

Image: VMware
Description
The management pack allows you to unlock the following use cases:

  • Provide a summary of performance, capacity, and configuration to Senior Executives and Virtual Infrastructure Administrators across all your vSphere environments.
  • Provide a unified view of events triggered across the virtual environments into a single pane for making it easier for NOC or Helpdesk to initiate action.
  • Ability to create a data warehouse where user selected set of metrics can be stored for data archiving and report use cases.
  • Ability to provide summarized views of health and configuration of your Software Defined data center stack. This includes core applications such as VMware vCenter Server, VMware NSX, and VMware vSAN. The solution also covers the management applications such as vRealize Operations Manager, vRealize Log Insight, vRealize Automation, vRealize Business, and VMware Site Recovery Manager.
Highlights
  • Provide a summary of performance, capacity, and configuration to Senior Executives and Virtual Infrastructure Administrators across all your vSphere environments.
  • Provide a unified view of events triggered across the virtual environments into a single pane for making it easier for NOC or Helpdesk to initiate action.
  • Ability to create a data warehouse where user selected set of metrics can be stored for data archiving and report use cases.

Technical Specifications

The vRealize Operations Federation Management Pack requires a dedicated instance of vRealize Operations Manager on which this solution is installed. The dedicated instance applies the management pack to communicate to your other vRealize Operations Manager instances in your environment to collect key metrics.

vRealize Operations Federation Management pack is compatible with:
  • vRealize Operation Manager 6.6 and 6.6.1 version.
