VMware VSAN – Virtual SAN – How to configure

This article shows how to enable a VMware Virtual SAN (VSAN) cluster within VMware vSphere.  If you are unfamiliar with VSAN, and what it is, I recommend reading the following articles. Duncan Epping’s Tech Preview of Distributed Storage Cormac Hogan’s Distributed Storage Tech Preview Lets start off by looking at the Pre-requisites of VMware VSAN, what do we need in place before we begin the configuration. Pre-requisites There are a number of pre-requisites that are needed, prior to configuring a vSphere cluster to participate as a VSAN.  The following list shows the minimum requirements to implement a VSAN. Minimum of three hosts. Each storage* host has a minimum of one SSD and one spindle hard disk. Each storage* host has a Pass-thru RAID controller as specified in the HCL.  The RAID controller must be able to present disks directly to the host without a RAID configuration. 10GB Network.  (1GB network […]

My VMware Home lab

I now have an updated VMware Home Lab, which you can read by clicking here. Here is my VMware Home Lab. People have been asking me to write about what I use in my VMware home lab that I use for a while. Finally one Saturday night, I have had the chance. Lets start off and talk about the physical hardware in my lab. 1 x HP ML115 G5 – Quad Core AMD Opteron 8GB RAM 2 x 256GB HD – RAID 1 2GB USB 2 x 1GB NIC 1 x 1GB On-board NIC 2 x HP Microserver N54L – 2.2Ghz 16GB RAM 4 x 256GB HD – RAID 5 2GB USB 2 x 1GB NIC 1 x 1GB On-board NIC 1 x Iomega PX4 2 x 1GB NIC 4 x 2TB HD – RAID 10 1 x Buffalo Linkstation Duo 2 x 500GB HD – Raid 1 2 x […]

UK National VMUG

UK National VMUG – Call for Papers

Simon Gallagher, one of the organisers of the UK VMUG sent an email out today asking for people to considering submitting “papers” for the UK National VMUG. Personally I think this is a great idea. I have enjoyed my trips to the UK VMUG and found the caliber of people at these events to be of the highest grade, with the sessions being as good as what you find at VMworld. This is a summary of Simon’s email: Hello friend of LonVMUG..(!), We (the LonVMUG committee) are putting together plans for the national UK VMUG on November 21st in Solihull, Brum (National Motorcycle museum). As you know I’m continually pushing for community content and ensuring that we as a VMUG provide the best community content of any VMUG, as well as excellent official VMware and sponsor content, as such I’ve opened up the community ‘call for papers’ for this event.

enumerate network adapters Powershell

Enumerate network adapters Powershell (PowerCLI) – VMware vmnic

This is a script I wrote a while ago to enumerate network adapters Powershell (PowerCLI) and add the total amount to a variable. I thought some people may find it useful. enumerate network adapters Powershell What I am achieving here is actually enumerating (count) the number of vmnic’s in a host. Why? Well if you think about automating your ESXi deployment, not all physical hosts have the same configurations, some have 4 1GB Nic’s others have 2 10GB nics, however you want to have a standard build for all configurations. This is an easy way to be able to automatically create the portgroups required without having to change your builds for different configurations. The script below shows how you can easily count the total number of vmnics and add to the variable no_nics. [powershell] $no_nics = get-vmhostnetworkadapter -Physical ##Sets Physical NIC count to -1 to match VMware NIC names, eg, […]
