One of the most repetitive questions that I get asked is which version of vCenter Server should I be using. This obviously is based on the decision between using the vCenter Server appliance (VCSA) introduced with vSphere 5.0 or the trusted and proven vCenter Server on Windows.
It has been general knowledge that the vCenter Server appliance, since its introduction has lacked features to that of its Windows counterpart. With vSphere 5.5 the vCenter Server appliance has come a long way, it supports all solutions that integrate with vCenter Server (vCD, vCOPs, SRM, VUM etc) but is it production ready? I can confidently say yes but will it meet your requirements? Continue reading →
Over the last few months, many customers have been testing and familiarizing themselves with vSphere 5.5 however deployment into a production environment is usually stalled until the availability of the first update or service pack. As we are nearing the typical time frame of when such an update or service pack may become available, I wanted to share some findings that may affect your deployment selection of vCenter Single Sign-On when deploying or upgrading to vCenter Server 5.5
During the installation of vCenter Single Sign-On server you are asked on the deployment option of the vCenter Single Sign-On instance. Below is the intended use case for each deployment option.
Many of you have now kicked the tires with vSphere 5.5 either in your home lab or on some servers at work and you’re anxious to get all the new goodies running in your production environment. Perhaps some of you early adopters are already running in full production, but we’re guessing many of you are just contemplating your major upgrade now.
VMware’s Tech Support staff tend to see a surge during the month of March in number of calls to support. But guess what? Many of the issues we’re anticipating are already resolved, and we’ve been busy compiling and documenting solutions to common problems that you can handle yourself.
Those of you installing or upgrading your vSphere hosts, and vCenter Server instances to version 5.5 will find the following KB articles and Support Insider posts of great interest.
You have probably heard the terms “Big Data” and “Hadoop” mentioned somewhere in the industry lately – they are both very popular subjects of discussion at the moment. This blog gives you an introduction to the core technology and explains some of the contributions that VMware continues to make to the Hadoop world.
I recently installed App HA in my lab and found some of the documentation unclear and at times hard to follow. I’m going to work with our Tech Pubs group to improve it. In the meantime I wanted to share what I learned to help make your installation easier.
First, pay attention to the pre-reqs!
Have DRS enabled on the cluster where you will be deploying the App HA appliance
Enable “VM and Application Monitoring” in your cluster HA settings
Create an IP Pool for the subnet(s) where you will install the Hyperic vApp
Have 3 static IP addresses ready for the App HA appliance, vFabric Hyperic Server & vFabric Hyperic Server DB
If you’ll want to use the email notification feature, make sure to configure email settings in vCenter
With those out of the way we are ready to get started. Here are the steps we are going to complete. I’ve broken this out into multiple posts to make navigating it easier.
I’m happy to announce the availability of a whitepaper that I had been working on much of the past year. Since I joined VMware back in January of 2013, an almost weekly request was for a whitepaper that help IT team explain the security of the VMware vSphere hypervisor, a.k.a. ESXi, to a security professional.
VMware vSphere Mobile Watchlist allows you to monitor the virtual machines you care about in your vSphere infrastructure remotely on your phone. Discover diagnostic information about any alerts on your VMs using VMware Knowledge Base Articles and the web. Remediate problems from your phone by using power operations or delegate the problem to someone on your team back at the datacenter.
IMPORTANT NOTE: A VMware vSphere installation (5.0 and above) is required to use VMware vSphere Mobile Watchlist. Access to your vSphere infrastructure may need a secure access method like VPN. Contact your IT department for further assistance.
While VMware highly recommends the deployment of all vCenter Server components into a single virtual machine (excluding the vCenter Server database), large enterprise customers running multiple vCenter Server instances within a single physical location can simplify the vCenter Single Sign-On architecture and management by reducing the footprint and required resources and specify a dedicated vCenter Single Sign-On environment for all local resources in each physical location.
For vSphere 5.5 the VMware recommendation is to centralize vCenter Single Sign-On when you have 8 or more vCenter Server instances in a given location (this is a soft recommendation).
Centralized vCenter Single Sign-On Architecture
Figure 1: A Centralized vCenter Single Sign-On Server environment
There can be increased risk when centralizing a vCenter Single Sign-On server (to why it is not recommended for smaller environments) due to the increased number of components affected if the vCenter Single-Sign-On server was to become unavailable, in short all vCenter Server components of all vCenter Servers registered will incur authentication loss (when compared to just the single vCenter Server instance when installed locally) and so availability of the vCenter Single Sign-On centralized server(s) is highly recommended.
