It’s that time of year folks, with the United Kingdom VMUG UserCon 2017 taking place on Thursday 16th November at the National Conference Centre, Birmingham.
This year will see Vice President & Chief Technology Officer, EMEA at VMware, Joe Baguley presenting the opening keynote, followed by an astounding list of technology breakout sessions and speakers, as well as the much coveted VMware Hands On Labs. This truly is an event not to be missed! Continue reading
Following a recent VMware Horizon 7 upgrade, we had a few issues whereby users were unable to download the VMware Horizon Client via the Web Portal. Specifically, clicking the Install VMware Horizon Client link simply resulted in a 404 error. So, where had the installation media gone?
On closer inspection, it appears VMware Horizon 7 handles this configuration slightly differently than in previous versions, but the issue can be easily remedied. Continue reading
If you’ve somehow managed to miss these brilliant (and free) VMware NSX guides, then worry not, as here are the links in all their glory. I cannot praise these books enough. Simply brilliant (and free!) Continue reading
Following on from my previous posts (What’s New in vSphere 6.5 and VMware VCSA 6.5: Installation & Configuration), a major area for discussion (and excitement) is the VMware Migration Assistant which, should you wish, is able to easily migrate you away from the Windows-based vCenter Server to the Linux-based vCenter Server Appliance (VCSA).

I’m a fan of upgrades that ‘just work’, but rarely do they run without a few unforeseens jumping out at you. Reading the VMware Upgrading VMware vCNS 5.5.x to NSX 6.2.x (2144620), I was surprised to see just five upgrade areas. Five? Really?? As this is a business critical system (and one with the potential of being able to turn a long day into an even longer day were things to go awry), I was a little sceptical, however, the vCNS to NSX upgrade process really is that easy.

A great new range of informational overviews is available via the VMware Product Walkthroughs website. Covering a range of product overviews (from vSphere 6.5, vRealize Network Insight, and more), to the specifics of vSphere 6.5 Encrypted vMotion, NSX VXLAN Configuration, Virtual SAN Fault Domains. Great on so many levels, enabling us to up-skill and dry-run new products, demonstrate solutions to management and technical teams, etc. Continue reading
A reoccurring issue this one, and usually due to a failed backup. In my case, this was due to a failure of a Veeam Backup & Replication disk backup job which had, effectively, failed to remove it’s delta disks following a backup run. As a result, a number of virtual machines reported disk consolidation alerts and, due to the locked vmdks, I was unable to consolidate the snapshots or Storage vMotion the VM to a different datastore. A larger and slightly more pressing concern that arose (due to the size and amount of delta disks being held) meant the underlying datastore had blown it’s capacity, taking a number of VMs offline.
So, how do we identify a) the locked file, b) the source of the lock, and c) resolve the locked vmdks and consolidate the disks?
Some time towards the end of Q4 2015, I was tasked with re-designing an Azure environment which had initially be commissioned to host a custom web solution by an outsourced team. The original design lacked any real resilience or high availability, with the solution itself being, for the most part, a collection of single instance servers. For example, SQL offered no HA via clustering or AAGs; no load-balancing had been implemented on the frontends, etc.
After a number of website outages due to server failures and/or high traffic volumes resulting in application crawl, the organisation approached my team with a request of redesigning the infrastructure.
My design was simple; I would continue to utilise Azure’s Infrastructure as a Service (IaaS) for the medium-term, deploy multiple, load-balanced IIS front-ends (which would eventually host the Sitecore Content Delivery nodes), and a simple, two-node SQL Always-On Availability Group (AAG) back-end with witness server.

Following the general release of VMware vSphere 6.5 last month (see my What’s New in VMware vSphere 6.5 post), I’ll be covering a number of technical run-throughs already in discussion throughout the virtual infrastructure community.
We’ll be starting with a fresh installation of the new and highly improved vCenter Server Appliance (VCSA), followed by a migration from the Windows-based vCenter Server 6.0; the latter task made all the easier thanks to the vSphere Migration Assistant. More on this to come. Lastly, I’ll be looking at a fresh installation of the Windows-based product, however, the experience throughout all of these installation/migration scenarios has been vastly improved.

One item I see mentioned fairly often, either in relation to personal labs or production environments, is the integration of vSphere SSO with Active Directory. Configuring vSphere’s SSO/AD integration via LDAP is a simple process, more so thanks to vSphere 6.5. Continue reading
