Forbes Guthrie released the VMreferencecard 1.0.1


Nadat op 3 februari de versie 1 release was uitgekomen zag ik en samen met mij nog een aantal mensen dat er nog een paar kleine foutjes in stonden. Deze heeft Forbes inmiddels gefixed.


  • Correction to partition types (thanks to Arne Fokkema)
  • Addition of SQL express with VC 2.5 (thanks to Peter Vroomen)
  • Added check license site
  • Random tidying

VMware: New Whitepapers

VMware heeft wat leesvoer uitgegeven voor het weekend.

Virtual Machine Failure Monitoring

VMware® High Availability (VMware HA) monitors your virtual infrastructure for ESX Server host failures and restarts virtual machines that are interrupted by those failures on alternate hosts. Starting with ESX Server 3.5, VMware HA can also detect and handle the failures of individual virtual machines and respond appropriately based on your specifications.
With this additional functionality, called Virtual Machine Failure Monitoring, VMware HA deals with both host operating system and guest operating system failures.

Firewall Configurations for Backup Clients on ESX Server 3

This document provides information about how to configure connections between different backup software products and VMware® ESX Server 3 hosts. The document explains how to open predefined firewall ports for supported backup products and how to open specific ports from a command line. If the backup product you use requires additional configuration changes to work with ESX Server 3, the document describes any specific steps you need to perform.

Round-Robin Load Balancing

VMware® ESX Server 3.5 and ESX Server 3i version 3.5 enhance ESX Server native multipathing by providing experimental support for round‐robin load balancing. This technical note explains how round‐robin load balancing works and how to set it.

Configuring and Troubleshooting N-Port ID Virtualization

N‐Port ID Virtualization (NPIV) is an ANSI T11 standard that describes how a single Fibre Channel HBA port can register with the fabric using several worldwide port names (WWPNs). This allows a fabric‐attached N‐port to claim multiple fabric addresses. Each address appears as a unique entity on the Fibre Channel fabric.
The primary source of information on configuring NPIV in a VMware Infrastructure 3 environment is the Fibre Channel SAN Configuration Guide, available on the VMware Web site.
This technical note provides additional details about certain specific NPIV configurations and information on diagnostic techniques that may be helpful as you configure NPIV. It also includes information to help you understand error messages that may appear as you are working with NPIV in a VMware Infrastructure environment.

Enabling NetFlow on Virtual Switches

NetFlow is a general networking tool with multiple uses, including network monitoring and profiling, billing, intrusion detection and prevention, networking forensics, and SOX compliance. NetFlow sends aggregated networking flow data to a third‐party collector (an appliance or server). The collector and analyzer report on various information such as the current top flows consuming the most bandwidth in a particular virtual switch, which IP addresses are behaving irregularly, and the number of bytes a particular virtual machine has sent and received in the past 24 hours.

VMware OVF Tool

The Open Virtual Machine Format (OVF) is a virtual machine distribution format that supports sharing virtual machines between products and organizations. The format facilitates the use of virtual appliances, which are preconfigured virtual machines that package applications with the operating system they require. Because OVF runs on multiple platforms, a virtual appliance is ready to run without significant additional configuration.

RTFM Guide: “What’s New & Different in Vi3.5″

Well, I’ve done it again. I’ve been on the Vi3.5 Beta Programme for sometime. I’ve written two guides – one of which is available today – on ESX3i and Vi-3.5. It’s the Vi-3.5 Guide that I am releasing today. It covers all the new features in this release, and also runs through lots of the minor enhancement that collectively amount to a major improvement from the initial Vi3.0.0 release

VMware: Reference Card (

Forbes Guthrie heeft de tijd vrijgemaakt om deze reference card te maken.

Op deze referencecard vind je de standaard procedures en commando’s voor ESX3.x en VC2.x. Ik zou zeggen een must have voor bij de reference MUG 😉

Zie de volgende website voor meer informatie:

Citrix: Performance of CPS based on Citrix Provisioning Server

Wilco van Bragh van heeft een artikel geschreven waarin hij een normale Citrix Presentation server(dus met fysieke hardware) vergelijkt met een virtuele Citrix Presentation server welke word aangeboden via Citrix Provisioning Server (voorheen Ardence).

Hieronder zie je een plaatje van zijn testomgeving.

VMware: Whats new with vI3.5

Bij de laatste Portland, Oregon VMUG meeting, is er een document gepresenteerd over de nieuwe features binnen VI3.5.

De volgende zaken worden er behandeld:

  • ESX 3i
  • DPM
  • Site Recovery Manager
  • VDM
  • etc

VMware: Virtualize SQL Server?

Op deze vraag heeft VMware een antwoord namelijk de volgende whitepaper: SQLServerWorkloads.pdf.

De bovenstaande whitepaper is een performance study van VMware en HP over hoe je een  SQL server wel of niet moet Virtualiseren.

Dit is de conclusie van de performance study:

The performance results we describe in this paper support the conclusion that running Microsoft SQL Server 2005 inside VMware virtual machines can provide an effective production-ready platform for running transaction-processing workloads.
Your IT organization can leverage the sizing data we present in this white paper to deploy Microsoft SQL Server successfully using VMware Infrastructure 3. By comparing effective workload throughput and resource utilization for your datacenter with the results presented in this paper, you can design and size your virtualized environment to meet your SLA targets.
The number of actual users and transactions you can support in a production environment will, of course, depend on the specific applications used and the intensity of user activity. The results of
Conclusions 12 VMware SQL Server Performance in a VMware Infrastructure 3 Environment
our tests clearly demonstrate that in a VMware Infrastructure 3 environment, the transaction throughput scales almost linearly even as the number of clients increases, for every configuration we tested. Our results show that the throughput rate of UP virtual machine is comparable for 32-bit and 64-bit environments. However, for SMP virtual machines, the throughput rate is slightly higher in a 64-bit environment compared to a 32-bit environment. Further, SMP virtual machines can service a higher number of users. One disadvantage of SMP virtual machines is that they have higher CPU costs per transaction than UP virtual machines. From a performance perspective, we recommend using SMP virtual machines rather than UP virtual machines for Microsoft SQL Server, and if possible, a 64-bit environment if your application stack supports it.
