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 Continue Reading

VMware DRS rule manipulation using PowerCLI (EMC VPLEX use case) Part 1.
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 Continue Reading
ESXi – Removing a stubborn Nexus 1000v VIB

VMware ESXi – Get VM’s by VLAN ID with PowerCLI
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 Continue Reading
EMC VNX – Self Help using “MyDocs”
I’m a big believer in “helping yourself”. By researching and actually doing things, we learn, grow and become more self-sufficient. I’ve blogged before about what I sometimes refer to as hidden gems, in particular MiTrend. There are other tools from EMC that are very useful. The first is My Documents Continue Reading

EMC-VNX 1/2 and ESXi: Potential Data Unavailability
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 Continue Reading
VMware NSX VCA-NV… So what ?
There’s no doubt Software Defined everything is big right now, and VMware NSX is probably King of the Hill. It’s a big focus of Vendor Roadshows and Tech Community events, and rightly so. As a customer, it’s not easy to get experience on such a platform. But as an influencer, Continue Reading
VMware PowerCLI – What are you waiting for ?
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 Continue Reading
