VMware Labs presents its latest fling CIM Plugin
• Enumerate system resources
• Monitor system health data
The plugin is general enough to support other CIM compliant services and is not limited only to ESX. The goal of this plugin was to expose ESX CIMOM in the vCenter Orchestrator.

Eric Sloof Receives the VCI Certificate of Achievement Award
This morning, during the VMworld 2011 Europe VCI day, I’ve received the VMware Certified Instructor Certificate of Achievement from Chris Cottam – Director, Education Delivery EMEA. I’ve received this award in recognition of my outstanding contribution; I’ve trained the highest number of students. I also have delivered very wide range of VMware training courses, my focus is on the advanced vSphere training courses. Besides delivering courses, I was an active participant in the vSphere 5 beta community. During the official launch at the 12th of July I created several vSphere 5 videos and made the recordings available via YouTube and iTunes. I was awarded as vExpert 2011 at the first of July and have passed his VCP5 exam at the end of September. During the VMworld 2011 in Las Vegas, I was a speaker and presented a top 3 rated session which was repeated twice due to its popularity. The “Myhtbusters goes virtual” session was very well received at the VMworld 2011 Las Vegas. Because of that, it will also run at the VMworld 2011 Copenhagen.

VMworld Europe 2012 – Barcelona
The VMworld, hosted by VMware, is the leading virtualization and cloud infrastructure event of the year. It's specifically designed for IT professionals seeking to accelerate success in their enterprises as they preserve existing investments while aligning their specific requirements to enable the cloud.
This year’s VMworld is about to kick off at the Bella Center in Copenhagen, but next year it will be more south, far more south… Barcelona.
Mark your agenda’s for some tapas – 16...18 October 2012 October 9th to 11th Spain will get hot and virtualized!!!

VMware View 5 Performance and Best Practices
Further this paper illustrates how, across all network configurations, View 5 delivers improved user experience compared with other VDI solution, while consuming significantly less bandwidth and CPU resources than Microsoft RDP7 and comparable bandwidth to Citrix HDX.
Finally, while the View 5 PCoIP protocol dynamically adapts to changing network and CPU constraints, ensuring great experience out-of-the-box, this paper lists a number of environment variables and VDI best practices that ensure users can get the most out of their VDI environment.

Best Practices for Performance Tuning of Latency-Sensitive Workloads in vSphere Virtual Machines
This white paper summarizes findings and recommends best practices to tune the different layers of an application’s environment for similar latency-sensitive workloads. By latency-sensitive, VMware means workloads that are looking at optimizing for a few microseconds to a few tens of microseconds end-to-end latencies; they don’t mean workloads in the hundreds of microseconds to tens of milliseconds end-to-end-latencies. In fact, many of the recommendations in this paper that can help with the microsecond level latency can actually end up hurting the performance of applications that are tolerant of higher latency.
- BIOS Settings
- NUMA
- Choice of Guest OS
- Physical NIC Settings
- Virtual NIC Settings
- VM Settings
- Polling Versus Interrupts
- Guest OS Tips and Tricks
VMware also has investigated the performance of two latency micro-benchmarks, one for Infiniband devices and another for networking devices, in VM DirectPath I/O (pass-through) mode, which bypasses most of the virtualization stack except the path for delivering interrupts from the underlying physical devices to the guest OS. Applying the recommendations reduced latency and therefore increased the score of these latency micro-benchmarks in a virtualized environment, bringing it closer to bare metal performance.

Video - What's new in VMware Data Recovery 2.0
With VMware Data Recovery 2.0, VMware has extended the ability to quickly and simply protect and restore virtual machines. Fully integrated with VMware vCenter Server, VMware Data Recovery gives central management of backup and restore operations, and the inherent deduplication of data saves significant disk space and provides flexible options for storage. VMware Data Recovery 2.0 has introduced a number of improvements including performance enhancements, speed, and reliability improvements, as well as capabilities to enhance management with the ability to email reports and schedule maintenance windows.
Several fixes have been included that rectify issues found in VMware Data Recovery 1.2.1. Issues that have been resolved include:
• CIFS target handling and resilience
• Incremental RDM backup
• Backups failing with “not enough disk space” errors
• Backups failing with “disk full” error despite free space being available
