When deploying Hadoop on vSphere, an important choice to make is the storage architecture for your data. There are several approaches to addressing this subject. We explore two important and contrasting approaches in this blog in order to help Hadoop architects understand their choices better. The different storage approaches described here are the direct-attached storage (DAS) one and the network-attached storage (NAS) style. We will see that these two can be combined together also to produce an elegant design for managing the different forms of data that appear in Hadoop/Big Data applications. Continue reading →
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 →
As I talk with more and more of our customers, it seems like there is an increasing number of IT/VMware admins that are experiencing “growing pains” in their environments. This does not come as a surprise if we consider the rates in which technology is exploding. Continue reading →
As many of you know, I work very closely with VMware Product Management and Engineering and we are always looking for data points to support concepts and aid the development of future generations with our products. We have created a 3 page survey that covers Performance and Availability within vCenter Server environments.
Help us make our products better by spending a few minutes to complete, your participation is much appreciated.
For those of you who have used vCenter Heartbeat to protect your vCenter instances, please be aware that we have announced the end of its availability as of today, June 2 2014.
Don’t worry though if you’re using it today; the current iteration will be supported through late 2018.
What does that mean? Are we getting away from protecting vCenter? Not by a long shot. We have big plans in this space. vCenter has become a very critical component of the infrastructure and we’re looking at lots of different means by which you can protect it.
What can you do first? Make sure you’re running it in a virtual machine! That gives you all the proactive benefits of downtime avoidance with DRS and Storage DRS, and the reactive benefits of automated restart with HA clusters.
As always make sure you have reliable backups (and test your restores!) of vCenter and its database.
The latest version of App HA, 1.1, was released last week and is now available for download. This release has a number of cool new features that will greatly increase the usability of App HA. I will do additional post(s) on these in the next few weeks.
Join our VMware Hands-on Labs Online Workshop on Tuesday, March 25th 10:00 AM PDT.
In our vSphere with Operations Management 101 online workshop, you will learn first-hand how vCenter Operations Manager can help you manage your vSphere environments. We will walk you through the steps to access the live vCenter Operations labs. Using the Hands-on Labs online portal you will be able try vCenter Operations Manager and chat with our VMware experts who use this product to monitor the Hands-on Labs infrastructure. Attend this online workshop to see how vCenter Operations Manager provides comprehensive visibility into the health and performance of your vSphere environments, helps you improve the efficiency of your virtual infrastructure, increase your consolidation ratios, and how it provides capacity management with “what if” planning capabilities.
This online workshop is targeted at customers who are running vSphere and who are new to vSphere with Operations Management.

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.
