Some solutions, such as VMware vCenter Site Recovery Manager, VMware vSphere Replication, or vSheild Manager are always installed on a different machine than the associated vCenter Server system or Platform Services Controller that manages the certificates for the solution.
Not too many people know about the intricacies of virtualization CPU scheduling and its impact on the performance of the VMs, so application owners out there – listen up! I’ve written about Ready Time (VMware ESXi) / Wait Time Per Dispatch (Microsoft Hyper-V) in the past, but a different challenge arises with VMs that have large vCPU count footprints. It’s called CPU Co-Stop, and it can devastate your application’s performance in a VM.
I wanted to upgrade my 6.0u1b Windows vCenters to 6.0u2 to start off the QA process, but unfortunately I hit a 1603 error. The TSE I worked with saw a few errors from VMware Syslog Collector and some internal PRs. The following is what he saw in my logs: [crayon-56fea372e991b958353812/] If you go… Read More »
Introduction This is Part 1 of a 2 part blog series. In this post we’ll talk about setting up RSA SecurID Authentication Manager, some architectural assumptions and what you’ll need to take with you to Part 2. Two Factor Authentication Two factor authentication (2FA) has become ubiquitous nowadays. For those of you still in the […] The post Two Factor Authentication for vSphere – RSA SecurID – Part 1 appeared first on VMware vSphere Blog .
As you might be aware, there have been a few storage-related issues with ESXi 6.0 as of late: Accidental PDL during dropped paths: Storage PDL responses may not trigger path failover in vSphere 6.0 (2144657) Host issues during smartd inquiries: Issuing a 0x85 SCSI Command from a VMware ESXi 6.0 host results in a PDL error (2133286) The question that comes up for the Pure Storage FlashArray is are we susceptible? The short answer is no. Let’s explain why.
Since the release of vSphere, you are able to Hot Add memory and vCPU. Quote from the VMware website: Virtual Machine Hot Add Support— The new virtual hardware introduced in ESX/ESXi 4.0 supports hot plug for virtual devices and supports addition of virtual CPUs and memory to a virtual machine without powering off the virtual machine. See the Guest Operating System Installation Guide for the list of operating systems for which this functionality is supported. So I wanted to see, if I was able to enable/disable this settings via PowerCLI and came up with a couple of functions.
In my final part in my series on Implementing a VMware Virtual Desktop Infrastructure with Horizon View 6.2 I showed how to deploy the View Access Point using ovftool. However, thanks to Chris Halstead there is an easier way. He has developed a tool to take the pain out of the deployment.
My first script that I ever wrote was a script to build VMs. I was the newest member on the team, and i was giving the task of building 50 VMs for a new project that was getting started. It was a very daunting task, due to the completion date to have these 50 VMs to be completed. So one of the other members of the team told me about PowerCLI, but didn’t have any knowledge about it.
VMware first introduced the vSphere Web Client with the release of vSphere 5.0. The vSphere Web Client would be the future management tool replacing the vSphere client aka “Legacy, Thick or C# Client”. This would be become more evident over time with each release of vSphere. New features could only be managed through the vSphere Web Client.
With the release of vSphere 6.0 Update 2 I needed to update my hosts! VMware Update Manager [VUM] makes updating and patching your environment very easy. It can also be used to upgrade VMTools and VMHardware versions on your virtual machines. In this post I will be installing VUM on Windows Server 2012 R2 VM using the SQL Express database and attaching it to my VCSA 6.0 U2 appliance. Once installed then I will use VUM to update my environment!
It’s been just over a week since VMware released vSphere 6 Update 2 and I thought I would go through some of the key features and fixes that are included in the latest versions of vCenter and ESXi. As usual I generally keep an eye out for improvements that relate back to Service Providers who use vSphere as the foundation of their Managed or Infrastructure as as Service offerings.

vSphere 6.0 Update 2 has launched and with it comes a very simple change with the way that VMs and Templates are evacuated from hosts that enter Maintenance Mode. In all prior versions, when a host enters Maintenance Mode, DRS will evacuate the host by placing all the running VMs, powered off VMs, and the […] The post Maintenance Mode Improvements in vSphere 6.0 Update 2 appeared first on VMware vSphere Blog .
