Which vCenter Server platform should I use – Appliance or Windows?

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.

whichplatform

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?

Getting ready to upgrade production to vCenter Server 5.5? Make sure you’re using the correct deployment option

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.

Installing or upgrading to vSphere 5.5 made a little easier

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.

Hadoop meets Virtualization – a Primer

 

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.

When to Centralize vCenter Single Sign-On Server 5.5

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.

PM Research: Managing Content with vCenter(s) – Quick Survey

As an admin in the data center, you have to

  1. Ensure that your VM templates are up to date
  2. Maintain a set of scripts for customizing the guest OS’s, installing custom applications, etc.,
  3. Share all of them across sites and vCenter instances.

Therefore, we at VMware are trying hard to provide you with a simple and efficient solution to manage your VM templates, scripts, ISO images, etc. – collectively called “Content”.

We now need your input to ensure that we understand your current infrastructure, methodologies, and core use cases so that we build the right set of features and for the right scale.

We have kept this survey really short (7 questions) and we’d appreciate you taking the time to provide us your feedback. Thank you!

vCenter Single Sign-On 5.5 – Backwards Compatible?

Part of my role at VMware is to  work closely with our customers and partners, sharing experiences and feedback with internal VMware Product Management and Engineers to help make our products better. One area that has been dominantly more focused than others over the last 12 months has obviously been vCenter Single Sign-On.

Due to this feedback, one of the drivers for the new vCenter Single Sign-On was to provide backwards compatibility and to highlight this, a recent Knowledge Base article released.
