Cybersylum

I hope finds you well!   If you get a minute, remind me what season it is. My house experienced killing frost and 70+ degree weather within a few days of each other. I am sure many of you felt it as well.   I can’t tell if we are in Ohio or Florida…

Upcoming Events

vSAN 7.0 and the Software Defined Data Center
Date: June 2nd
Time: 9am Eastern

This virtual event will review vSAN 7.0 – the cornerstone of the Software Defined Data Center. In this session we will do an overview of vSAN for those who need a refresher, delve into the new features that were released then dive into a live demo of vSAN where we will show the power of Hyper Converged Infrastructure and how it is transforming the modern data center. We look forward to seeing you in this interactive session!

Guest Speaker:
Max Abelardo  – VMware Systems Engineer

Welcome to (hopefully) the tail end of winter! A few brief glimpses of sun has me hopeful that the dreary days are behind us!

There is a lot of VMware Virtualization news to cover this month.  Some important changes are noted in the Highlights section

Highlights for the Month

vSphere 6.0 & vCenter Server 6.0 will be at End of General Support on March 12th, 2020. Note:  Even if your hosts won’t support a later version of vSphere, if they are on at least 6.0, you can still update vCenter Server to 6.5 or 6.7

Microsoft changes to LDAP Binding Requirements may impact vCenter Server and App Volumes
Apparently Microsoft will be changing how AD handles LDAP requests in their March 2020 updates.  Any LDAP requests that are not using TLS could be negatively impacted. The tech marketing team for vCenter has written an article on how these changes to MS LDAP Channel Binding & Signing could affect vCenter.

There are 3 protocols that will bind vCenter to Active Directory for authentication:

• Unencrypted LDAP (LDAP:\\)
• LDAP encrypted with TLS (LDAPS:\\)
• Integrated Windows Authentication (IWA)

According to VMware testing, TLS\LDAPS and Integrated Windows Authentication binding methods are not impacted by this change.    I have received customer feedback that the MS tool that helps report on unencrypted LDAP requests is including applications that are using IWA bindings.

It appears App Volumes could be impacted as well.  There is a KB article (KB 77093) that discusses what VMware is working on for this and what you can do about it.

Upcoming changes to VMware CPU-based licensing
Beginning April 2nd, 2020, Any VMware software that is licensed on a per-CPU basis will require 1 CPU license for up to 32 physical cores.  If a CPU has more than 32 physical cores than an additional CPU license will be required.  You can read the full VMware CPU Licensing Change Announcement, as well as check out KB 77098, which describes how you can count the CPU cores in your environment (either using the vCenter Client or a PowerShell script).

Adobe Flash is near End of Life
Adobe has announced that they will EOL Flash at the end of 2020.  This likely means that browser manufacturers will stop supporting Flash-based apps in their browsers at some point this year.  (The Adobe article has links to the major browser partners and their plans)

The vSphere Web Client included with vCenter Server 6.7 releases (beginning in April 2018) have full HTML5 feature parity and no longer require Flash.  If you haven’t upgraded yet, now is the time to start planning.    A few things to check before you upgrade:

• Host Compatibility – The hosts don’t have to run the same version as vCenter.  There is a interoperability matrix to show compatible versions.  Hint: vSphere 6.0 & Later
• Software Compatibility – make sure any solutions that integrate with vCenter are supported.  VMware has a searchable Product Interoperability Matrix for products like Horizon, vRealize, etc.   You should also check any third-party solutions (backup, reporting, etc)
• vCenter Client Plugins – If you use a client plugin to manage your SAN, A/V, etc you should also check with that vendor to make sure it is supported.

I hope everyone had a Happy New Year!  2020 is off to a rapid start.  I continue to write 2019 as the date (per usual).

Product Support Highlight

• A number of core vSphere products are nearing the end of General Support (particularly vSphere 6.0 & vCenter Server 6.0 in March).  You can find out the exact date in the Product Watch section.

Upcoming Events

Cleveland VMUG
Date: Tuesday, January 28th
Time: 9:30AM – 4:00PM

Learning Docker & Kubernetes on a boat!
Docker and Kubernetes have become household words in most IT shops during this session you will have the opportunity to learn about them hands-on.  We will discuss basic constructs then put that knowledge into action in provided lab environments.  You will have the opportunity to deploy, operate and troubleshoot container applications.  You should leave this session with a basic knowledge of how to operate Kubernetes in enterprise environments.  Lunch will be included during this six-hour event at the LeanDog HQ in Cleveland.

Requirements: Each attendee needs to bring a laptop with wireless connectivity that will allow them to operate the labs.  In order to access the labs everyone will need to have a free mylearn.vmware.com account.   Attendees need to verify their ability to login to mylearn.vmware.com in advance of the lab.

Hello everyone!  I can’t believe it is the end of November already.  Thanksgiving is nearly upon us so I’ll keep the virtualization news light.  A few key things this month:

• A number of core vSphere products are nearing the end of General Support (particularly vSphere 6.0 & vCenter Server 6.0).  You can find out the exact date in the Product Watch section.
• The last Ohio SLED VMUG for 2019 is on 12/3.  We will be talking about VMware Skyline and a recap of VMworld.  Arctic Networks is sponsoring and will be presenting on the Security Operations offering. We hope to see you there!  You can register at VMUG.COM.
• Earlier this month I sent out a message about a new Speculative Execution bug (VMSA-2019-0020).  The full remediation for this issue has 2 parts (patch the code and make a config change to enable the full fix).  The required config change is noted in the advisory but unfortunately is a bit buried.  You can find the details in KB 59139.  This is linked in the overall advisory but isn’t called out as well as it could be.  Please read the full document.  There are performance impacts – particularly for anyone running Nested Virtualization.

Upcoming Events

Ohio SLED VMUG
Date: Tuesday, December 3rd
Time: 8:30AM – 11:30AM
