It’s June already, time flies when you are having fun right? This month there have been three new and five updated flings. In the category new there is an ESXi Compatibility checker, DRS Entitlement viewer and the Cellular Module User Space USB Driver on ESXi. In the updated category we have the eternal HTML5 vSphere web client, I/O Analyzer, Desktop Watermark, Cross vCenter Workload Migration Utility and last but not least Blockchain on Kubernetes.

ESXi Compatibility Checker
This is a new fling that makes it easier to check if you’re hardware is still supported by VMware. It does require python to be installed.
The ESXi Compatibility Checker is a python script that can validate VMware hardware compatibility and upgrade issues of ESXi.
VMware hardware compatibility and product interoperability need to be validated when new hardware is installed on an existing ESXi or when a VC/ESXi version needs to be upgraded. Unfortunately, it is not a trivial task as the compatibility information is scattered in multiple web pages. The user needs to understand the data and validate them one by one manually. This process is tedious, laborious and often prone to error when done at scale.
This Fling will provide a simple and easy way to collect server and IO device details from ESXi and provide a command line interface to validate their VMware compatibility and upgrade issues. Users no longer need to understand compatibility details or manually compare the dataset to find out compatibility or upgrade issues. The Fling can generate a compatibility report for many ESXi managed by a VC with a simple command.

DRS Entitlement Viewer
This HTML5 client plugin shows entitled resources per VM and resource pool.
DRS Entitlement Viewer is installed as a plugin to the vSphere client. It is currently only supported for the HTML5 based vSphere client. Once installed, it gives the hierarchical view of vCenter DRS cluster inventory with entitled CPU and memory resources for each resource pool and VM in the cluster.
Entitled resources can change with VMs’ resource demand and with the VM’s and resource pool’s reservation, limit and shares (RLS) settings. So, customers can get the current entitlements based on the VMs’ current demand and RLS settings of the VMs and resource pools.
DRS Entitlement Viewer also provides 3 different What-If scenarios,
1. Changing RLS settings of a VM and/or resource pool
2. What-If all the VMs’ resource demand is at 100%
3. Both 1 and 2 happen together
Customers can pick one of the 3 scenarios and can get new entitlements without actually changing RLS settings on the cluster.
Finally, DRS Entitlement Viewer also provides an option to export the new RLS values from a What-If scenario as a vSphere powercli command which customers can execute against their vCenter to apply the new settings.
- First public release May 29, 2018 v1.0.2

Cellular Module User Space USB Driver on ESXi
The Cellular Module User Space USB Driver on ESXi provides you with a driver so you are better able to use a cellular module form ESXi.
IoT is growing rapidly so many users would like to enable ESXi on their IoT devices. Driven by VMware’s virtualization technology, which can help them address some challenges like security issues, fragmentation, multi-tenancy, etc. The reality is that many of those IoT devices have a variety of devices and busses that ESXi does not support. The Cellular Module is one of those devices in the case of IoT. Typically, these devices have to communicate with their own remote management center.
This Fling provides a driver to enable deployment on ESXi on their IoT devices. Note that this driver is running in UserSpace mode. While many widely used IoT Edge Gateways are equipped with a cellular module, ESXi does not have a driver to activate that cellular module. So our cellular module userspace USB driver can enable that hardware module to communicate with a remote cloud server.

vSphere HTML5 Web Client
The fat client’s already gone, the flash client is on its way out so better get used to the vSphere HTML5 Web Client!
Fling 3.38 – Build 8535804
- Guest OS User Mappings for VMs
- Serial port support for VMs
- Improved search including
- New redesigned search results page
- VM search results has filters such as power state, guest os, host, clusters, datacenter
- Save search
- VM Quick power operations
[sta_anchor id=”ioanalyzer” /]
The I/O Analyzer doesn’t get a lot of updates so you might not have heard of it. Like the names says it’s a very usable tool to test your storage performance.
VMware I/O Analyzer is an integrated framework designed to measure storage performance in a virtual environment and to help diagnose storage performance concerns. I/O Analyzer, supplied as an easy-to-deploy virtual appliance, automates storage performance analysis through a unified interface that can be used to configure and deploy storage tests and view graphical results for those tests. I/O Analyzer can use Iometer to generate synthetic I/O loads or a trace replay tool to deploy real application workloads. It uses the VMware VI SDK to remotely collect storage performance statistics from VMware ESX/ESXi hosts. Standardizing load generation and statistics collection allows users and VMware engineers to have a high level of confidence in the data collected. Please post comments and questions regarding this fling to the I/O Analyzer Community.
- Integrated framework for storage performance testing
- Readily deployable virtual appliance
- Easy configuration and launch of storage I/O tests on one or more hosts
- Integrated performance results at both guest and host levels
- Storage I/O trace replay as an additional workload generator
- Ability to upload storage I/O traces for automatic extraction of vital metrics
- Graphical visualization of workload metrics and performance results
New in version 1.6.2u1
- Support vSphere 6.5 onward
- Upgrade to OpenSSL 1.0.2o
- Hot patch script to live upgrade existing 1.6.2 VMs
[sta_anchor id=”watermark” /]
Desktop Watermark is a tool that adds a visible or invisible watermark to a VDI Desktop. This can be used for auditing for example.
- Added support for multiple monitors.

Cross vCenter Workload Migration Utility
I used the Cross vCenter Workload Migration Utility myself this week when I wanted to clone my golden image to the not linked vcenter servers in my lab. Yes it can also clone besides just moving the servers. I might end up putting up a seperate blog post about this.
Version 2.0, May 4, 2018
- Added support to select individual host as the placement target
- Added support for migrating VMs with shared datastore
- Added clone functionality in addition to relocate
- Added resource summary details for placement targets
- Added a prompt to verify site thumbprint during SSL verification
- Added a link to refresh vm list in the inventory view
- Updated REST APIs to add operation type parameter

Blockchain on Kubernetes
Not a blockchain person myself (yet) but this is the former Blockchain on vSphere fling that has been renamed to Blockchain on Kubernetes
Blockchain is an emerging technology which has been gaining traction globally throughout the past few years. Industries like finance, logistics, and IoT are actively working on research and pilot projects using blockchain.
Fabric is a sub project under Hyperledger (a LinuxFoundation project), it is probably the most mature blockchain solution available now for business use cases.
The mission of Blockchain on Kubernetes (formerly named Blockchain on vSphere) is to provide an end-to-end blockchain solution, from IaaS, to Blockchain platform and Blockchain applications. It allows organizations to quickly collaborate and evaluate the new business models and processes by using the decentralized blockchain technology.
By using BoK, blockchain developers can use BoK command line tool or a GUI tool provided by BoK PCF Tile to quickly set up an environment to build and test their blockchain applications.
May 3 2018, BoK 2.0
- Provide a new PCF Ops Manager Tile to deploy Hyperledger Fabric. It supports creating Kubernetes cluster via PKS Tile and deploy Hyperledger Fabric in the Kubernetes cluster.
- Add a central config file bok.yml to specify all BoK configuration. No more manual code change is needed.
- Support kafka as consensus mode.
- Other enhancement for stability.
- Verified against Kubernetes 1.9.7.
