I recently had a design discussion about the best way to configure the VMware Fault Tolerance Logging network. During the discussion we quickly established that you want to assure redundancy for the VMware FT Logging network. The most interesting part of the discussion was how to configure the vSwitch dedicated for FT traffic.

BIOS settings in a VMware ESX(i)/vSphere Environment
Over the last period I’ve noticed that a lot of customers aren’t aware of BIOS settings that can be changed as a best practice for VMware ESX(i)/vSphere environments. In this article I want to outline some of these best practices specifically based on HP Hardware, but feature-like options are available within other vendors as well. […]

Running vMA 4.1 on VMware Workstation
After importing the new vSphere Management Assistant (vMA) 4.1 on my VMware Workstation 7 environment I noticed that it boots with a memory crash error, an “unable to access resume device” message and eventually ends with a kernel panic. The memory crash error seems like something that can be ignored and which is covered by several blog articles […]

Microsoft Cluster Service support on vSphere (iSCSI)
Lately a customer asked me about Microsoft Cluster Service support on a vSphere iSCSI environment. The VMware Documentation for vSphere and vSphere Update 1 states: Before you set up MSCS, review the list of functionality that is not supported for this release, and any requirements and recommendations that apply to your configuration. The following environments and […]

How to quickly discover a "VM to Resource Pool" mapping
Everyone knows the situation in where a (s)VMotion asks you to select a Resource Pool. I would love to see that VMware automatically selects the current VM’s Resource Pool but unfortunately we have to make a selection since it defaults to the cluster. When we leave it to default it obviously causes the VM to […]

SCSI Bus Sharing on the VM Boot Disk SCSI Card
Lately I’ve been asked to review a PID (Project Initiation Document) for a new File Server project based on Linux/GFS v2 (General File System) hosted on VMware vSphere. I noticed that the PID was talking about a dynamic File Server that could (and even would) grow towards 100 TB storage space. That number immediately set […]

VMware vCenter Storage Views: Partial/No Redundancy
While exploring my software iSCSI initator environment I noticed that all my VM’s on every host are reporting a “Partial/No Redundancy”-status within the Multipathing Status even though I have Round Robin in place and thus 2 paths to the storage. This behavior is a bug as confirmed by VMware Technical Support. The rule for displaying […]

Testing Scenario's VMware / HP c-Class Infrastructure
Since my blog about Understanding HP Flex-10 Mappings with VMware ESX/vSphere is quite a big hit (seeing the page views per day) I decided to also write about the testing scenario’s which should all be walked through before taking a design as this into production. In my blog I stated: Last word of advice: while implementing […]
