During the Dutch VMUG 2009 event NGN’s Community Master, Melle Gloerich has recorded a interview between Bouke Groenescheij and Wietze Albers. They are talking about performance in a VMware enviroment.

Upcoming vSphere Courses: Design Workshop and Manage for Performance
VMware's Education Services has launched two new vSphere beta courses:
VMware vSphere: Design Workshop
This course explores a design methodology, criteria, and approach for designing a VMware vSphere™ 4 virtual datacenter architecture consisting of VMware ESX™/ESXi 4 and VMware vCenter™ Server 4. This course, by discussing the benefits and risks of available design alternatives, provides information which supports making sound design decisions. This course also provides an opportunity to practice your design skills by working with peers on a design project.
VMware vSphere: Manage for Performance
This hands-on training course explores the management of performance in a VMware® vSphere™ environment. It provides the knowledge and skills necessary to make fundamental design decisions that enhance performance and to meet performance goals in an already-deployed vSphere installation. The course is based on ESX 4.0, ESXi 4.0, and vCenter Server 4.0.

What’s the benefit of vCenter Server Heartbeat
I often speak to people who prefer a virtual machine protected by VMware HA for hosting their vCenter Server instead of using vCenter Server Heartbeat but vCenter Server Heartbeat offers some real great benefits compared to VMware HA. VMware HA only works with virtual machines and protects the operating system and hardware. HA also needs shared storage. vCenter Server Heartbeat is able to clone, synchronize and do real-time replication. vCenter Server Heartbeat works with either virtual machines or physical machines and protects the operating system, the hardware, and the application. You don’t need shared storage but redundant storage. I’ve created a little demo movie showing the vCenter Server Heartbeat console and a real fast switchover to the secondary server.
Top 25 bloggers - Vote and Win a vSphere DVD training course
Eric Siebert over at vSphere-land is running a new blog contest which let you decide who the most favorite blogger is. You can pick your 10 most popular bloggers; based on your points Eric Siebert will create a vSphere-land blogger top 25. Please cast your vote and make a change to win a copy of the TrainSignal vSphere DVD training course.
Update from @ericsiebert via Twitter: Voting closes Friday for top bloggers, 800+ votes already, results will be published next Monday vote.vsphere-land.com

CPUID System Information
I’ve created a new Virtualization EcoShell PowerPack with only one Script Node and it’s called “CPUID System Information“ which shows the VMHost CPU Info. The inspiration for building this new PowerPack came from VMware’s evangelist Richard Garsthagen who has built the well known Visual Basic Application, VMware CPU Host Info. “CPUID System Information” is completely based on PowerShell and VMware’s PowerCLI. The script is able to show you which features (CPUIDs) are available on your ESX server’s CPUs. Besides checking VMotion compatibility it also shows you:
- Enhanced VMotion Compatibility (EVC) levels which simplifies VMotion compatibility issues across CPU generations. EVC automatically configures server CPUs with Intel FlexMigration or AMD-V Extended Migration technologies to be compatible with older servers.
- All the important CPU features like: VMX, MONITOR/MWAIT , SSE3, SSSE3 ,SSE4.1 ,SSE4.2 ,CMPXCHG8B ,CMPXCHG16B ,NX/XD ,Long mode support ,RDTSCP ,3DNow! ,3DNow! Extensions ,FFXSR ,Prefetch instructions.
I’ve three versions available for download.
The first one can be used as a PowerPack in the Virtualization EcoShell.
