Dell EMC Unity and VMware VVols – What’s all the fuss? Pt1

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, but I was always sceptical and… Read more »

Azure AD Connect Synch Error- Target Attribute Value length exceeds max allowed size.

Like most admins, (So I’m told!), I’ve found the  Azure Active Directory Synch tool spit out some rather random quirky errors from time to time. The synch engine has a long pedigree from Gal synch, FIm etc. Solid, but temperamental. The dreaded notice in the Office 365 Dashboard; Today’s verbose error error was “sync-general-failure”. Very helpful, so let’s start digging…. Read more »

Useful Search utility – Everything

      1 Comment on Useful Search utility – Everything

I’ve often been underwhelmed by the performance of the built-in Windows Search utilities, particularly for simple searches like finding filenames containing a specific string. That led me to search for something better.

AWS and PowerShell – Let’s be friends Part 1

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 can be referenced and downloaded… Read more »

Quick Fix-VMware Workstation- The user did not accept the license agreement by passing EULAS_AGREED=1 on the command line

One of the nice benefits of being a vExpert is the licenses kindly provided to various VMware apps including VMware Workstation. After receiving the codes this year and downloading the latest version, it should have been a simple process to install, right ? Dbl-Click, next, next, next…. ? Moments after confirming the UPGRADE dialog, i was surprised to see a warning;… Read more »

ESXi 5.5 – Automating VMFS UNMAP w/ PowerCLI and PowerShell

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; ESX Virtualization Vladan Seget VirtualizationIsLife  Anthony… Read more »

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 a VPLEX Metro configuration, a VPLEX detach rule is defined… Read more »

Dell PowerVault MD3660f – Firmware Upgrade Process

The DELL PowerVault MD series Storage Arrays are solid and reliable units. Whilst I don’t use any for what may be considered “Primary” Storage, I use them for many workloads. Backup targets, Image Respositories, Archives, Unstructured data etc. In a 5 RU form factor, it’s a dense package with over 120TB of usable capacity.            Generally… Read more »
