VMware: Reference Card (vmreference.com)


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 😉

Citrix: Performance of CPS based on Citrix Provisioning Server


Wilco van Bragh van http://sbc.vanbragt.net 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: 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.

Citrix: How to Publish Explorer.exe with Specific Drives, Specific Folders, or URL


Citrix heeft een artikel vrij gegeven over het publiseren van Explorer.exe.

Summary

This document describes a method to publish specific drives and folders as it is not recommended to publish EXPLORER.EXE directly (see MS KB 832427).

    Note: The method of copying and renaming the EXPLORER.EXE to, for example, EXPLORER2.EXE is a widely used but not suggested or supported method by the Citrix Development Team. When doing this, there may be other side effects like session hangs or sessions getting slow when launching several instances of the renamed EXPLORER2.EXE. These issues are the result of internal EXPLORER.EXE dependencies that cannot be resolved without rewriting large parts of the kernel OS.

Citrix recommends you publish IEXPLORE.EXE, with the -e parameter, to provide the functionality of a published EXPLORER.EXE instead.

Whitepaper: Installing ESX 3.0.x without isolating the SAN


Do you find detaching SAN cables or organising LUN masking a hassle each time you build or rebuild a VMware ESX Server?  This paper shows you how to streamline the process by not loading HBA drivers during the initial installation process.

For any suggestions or corrections please contact Dinny at dinny.davies@googlemail.com

Mocht je met deze whitepaper aan de slag gaan, lees dan heel erg goed. Dat bespaard je een hoop tijd 😉

Whitepaper: Using MSCS to Cluster VirtualCenter


In a default installation, VMware VirtualCenter 2.x runs on a single Windows-based server. In order to provide
high availability, you can use clustering software so the VirtualCenter server process is automatically restarted
on a standby server if the primary server fails.
This document describes the use of Microsoft Cluster Server (MSCS) to provide high availability for
VirtualCenter. This capability is available in VirtualCenter 2.x starting with VirtualCenter 2.0.1 Patch 2. You
can implement the clustering architecture described in this paper whether VirtualCenter runs on a physical
server or in a virtual machine, although in the latter case you must adhere to the further restrictions on
clustering virtual machines as documented in the Setup for Microsoft Cluster Service guide
