The reward for effort when scripting is almost always worth it. Today I had the task of removing a particular AntiVirus product from a 36 host VDI cluster. Part of this requires the removal of NSX-Manager and all the groovy components it uses to do it’s thing, including a vSwitch on every host, with multiple […]
There’s been lots of talk about the wonders of VVols for a long time. They seemed to be a large amount of hope that they would be the panacea of all our Storage and Virtualization woes and be the vision going forward, at least for our  VMware environments. The hype seems to have tapered off, […]
     There’s always been a number of ways to apply filters to VM’s and disks. It could be done at the Backup-Set or Sub-client level. This is a little bit clunky and can lead to unnecessary VM’s being backed up.  If you’re using a Capacity based licence, this is obviously not optimal. Space is […]
I first used AWS approximately 4 years ago. At that time, programmatic management of services was not an easy hurdle to jump and required regular ‘feeding & watering’. Naturally, these tools have matured greatly so whatever tool-set you are most comfortable with has a well developed set of features/options available for you to use. These […]
With vSphere 6.5 recently released, a nice feature was the automated execution of the UNMAP command against thin provisioned datastores to reclaim space. This requires no user interaction, it’s fully automated for you and can free up significant amounts of space from your datastores. There’s some good information regarding the v6.5 release  on these blogs; […]
VPLEX is another of my favourite products,  and for good reason. I currently run a Metro cluster underneath a VMware platform that has proven to be super reliable. One important design consideration for this is to ensure that VM’s are configured for site bias. Why ? Glad you asked. In a VPLEX Metro configuration, a […]
Often when when working in large environments you’ll get interesting requests. These may be to assist in troubleshooting, auditing, reporting or any other reason. I was recently requested to provide a list of mac addresses for every VM with a vNIC in a specific vlan. I had a feeling this was going to be a repeated request […]
Another ETA hit my inbox over the weekend, this time relating to VNX/VNX2 and ESXi where a condition that could result in data being unavailable exists. If you are running a VNX and have a code base  of 05.32.000.5.219 or earlier or a VNX2 with codebase lower than 05.33.006.5.102 and earlier you may be affected. The […]
I still talk to people who are reluctant to jump in and learn some basic scripting techniques. Usually their response is that it’s easy in the gui or “scripting is hard” or the “I’m not a developer so why bother ?”. Meh, make it happen. The facts is, learning some basic scripting techniques will save you […]
