As it was fathers day yesterday and I also had to fly out to London I totally forgot to hit the "publish" button. I did however create a Top 5:
- David Davis – VIDEO: Mike DePetrillo speaking on VMware vCloud
One of the most controversial parts of Mike’s presentation is when he says that vCloud is really sold to the CIO and the message to the IT group is that you will have to change in order to keep your job. In other words, “the cloud” will assimilate the infrastructure as we know it and IT people will have to adapt to that, improving their skill set, in order to move to different roles in the IT organization where they can accomplish the more important IT projects with real ROI (not just maintaining the SAN LUNs, or whatever they do). Watch the video to hear the vCloud message for yourself… Note: Mike doesn’t show a “Project Redwood” demo – sorry.
- Eric Sloof – StarWind iSCSI multi pathing with Round Robin and esxcli
After you have created a StarWind iSCSI target, it’s ready to service connections. You can established a connection to an iSCSI target and it appears as a new datastore on your ESX server. I’ll show the operations you need to complete to create and format the datastore in the way your ESX server can create virtual machines on it.
I’m also going to show how the esxcli command can be used for PSA (pluggable storage architecture) management and explain how to use the vSphere Client to manage the PSA, the associated native multipathing plug‐in (NMP).
- Tod Muirhead – Scale-Out Performance of Exchange 2010 Mailbox Server VMs on vSphere 4
The performance in the 4000 user tests shows a rise of only 30ms in the 95th percentile SendMail response time between a single 4-vCPU VM and four 1-vCPU VMs. The 8000 user tests show an increase of approximately 140ms in the same metric when comparing the single 8-vCPU VM with four 2-vCPU VMs. Even though this is a significant percent increase, the absolute increase is still relatively small in comparison to the 1 second threshold which is where users will begin to perceive a difference in performance.
- Martin Klaus – Operations Management in the Virtualized Environment – What’s different?
As the foundation for the Private Cloud, virtualization enables server, storage and networking resources to be shared very efficiently across applications. Virtualization also allows you to standardize your service offerings. Templates for your corporate Windows or Linux images can be provisioned as virtual machines in minutes. Even higher-level server configurations with complete web, application and database server stacks can become building blocks for your Enterprise Java environments or Sharepoint instances, further simplifying the provisioning process and lessening the need for one-off admin tasks. Automated backup, patch and update processes are additional benefits that are easy to realize with virtualized infrastructure.
- Scott Lowe – The vMotion Reality
In his article, Benik states that the ability to dynamically move workloads around inside a single data center or between two data centers is, in his words, “far from an operational reality today”. While I’ll grant you that inter-data center vMotion isn’t the norm, vMotion within a data center is very much an operational reality of today. I believe that Benik’s article is based on some incorrect information and incomplete viewpoints, and I’d like to clear things up a bit.
