History of vSphere Storage Size Limitations
This seems like a straightforward topic. If you are on vSphere 6 you can create VMFS datastores and VM disks as big as 64TB (62TB for VM disks to be precise). The reality is, not all customers are running the latest and greatest for various reasons.
VAAI XCOPY not being used with Powered-On Windows VM
This is an issue I discovered along with my good friend and former colleague Drew Tonnesen a few years back which has cropped up a few times in recent days. I noticed there wasn’t really any information about it online, so made sense to put a quick post together.
that virtual boy: VMware’s new Virtual Technical Advisor (VTA) Service
Anyone familiar with VMware’s Technical Account Manager (TAM) services knows the benefits to having such a resource as your advocate. Our customers gave TAM services a Net Promotor Score (NPS) of 67.5%, which is incredibly high for such a paid service. We’re in an age where great software paired with great services is the best way to squeeze the most value out of your investments. Adopting new technologies, embracing the Cloud, exploring hyper converged infrastructure can be daunting tasks. VMware wants you to be confident in your endeavors and that’s where the Technical Account Manager and Virtual Technical Advisor services come in!
Yellow Bricks: I have memory pages swapped, can vSphere unswap them?
“I have memory pages swapped out to disk, can vSphere swap them back in to memory again” is one of those questions that comes up occasionally. A while back I asked the engineering team why we don’t “swap in” pages when memory contention is lifted. There was no real good answer for it other than it was difficult to predict from a behavioural point of view. So I asked what about doing it manually? Unfortunately the answer was: well we will look in to it but it has no real priority it this point.
VMWerni: Change OS (from Windows 2008 to Windows 2012 R2) of vCenter 5.5 – Change vCenter 5.5 SSO architecture, virtualize a physical vCenter 5.5
The following checklist describes the process of migration the vCenter 5.5 OS (for example from Windows 2008 to Windows 2012 R2) by actually re-installing a fresh vCenter 5.5 – using the exsitsing vCenter database, inventory database and certificates. A follwoing step could be to update this “refreshed” vCenter 5.5 to vCenter 6.0. – And yes I am talking about Windows vCenter to Windows vCenter I am not talking about vCenter appliance.
Home Lab fundamentals: Time Sync
First rule of Home Lab club, don’t talk about time sync! Or so it seems. When starting your home lab, all hints and tips are welcome. The community is full of wisdom, however sometimes certain topics are taken for granted or are perceived as common knowledge. The Home Lab fundamentals series focusses on these subjects, helping you how to avoid the most common pitfalls that provide headaches and waste incredible amounts of time. A ‘time-consuming’ pitfall is dealing with improper time synchronization between the various components in your lab environment.

Virtual Blocks: Is Storage DRS Still Needed With Virtual Volumes?
A question that has been coming up frequently in conversations I have had with customers is why Storage DRS is not supported with Virtual Volumes or Virtual SAN? In fact this question came up again in a customer call on Thursday morning with one of our customers who wanted to understand more about the benefits of Virtual Volumes. Taking onboard the advice that if you are asked a question more than twice it’s worth writing a blog post about it I decided it was about time that I wrote up my thoughts on the topic!

virtuallyGhetto: Getting Started with Tech Preview of #Docker Volume Driver for #vSphere
A couple of weeks ago, I got an early sneak peak at some of the work that was being done in VMware’s Storage and Availability Business Unit (SABU) on providing storage persistency for Docker Containers in a vSphere based environment. Today, VMware has open sourced a new Docker Volume Driver for vSphere (Tech Preview) that will enable customers to easily take advantage of their existing vSphere Storage (VSAN, VMFS and NFS) and provide persistent storage access to Docker Containers running on top of the vSphere platform. Both the Developers and vSphere Administrators will have familiar interfaces in how they manage and interact with these Docker Volumes from vSphere, which we will explore further below.
#vSphere Client timeout after replacing Machine SSL Certificate
The last few days I have been troubleshooting a very strange issue with the C# vSphere client on a new vSphere 6.0 install for a customer. The vSphere Client was initially working fine, until I replaced the Machine SSL Certificate for vCenter. After the Machine SSL Certificate was replaced, the vSphere client would timeout on connection. The issue was only connecting to vCenter, if connecting the vSphere client directly to hosts the client worked fine.
Latest Fling from VMware Labs – #VMware Logon Monitor
VMware Logon Monitor logs a wide array of metrics related to logon, group policy, user profile, and performance. These metrics were selected to provide administrators a detailed view of end user systems during logon time so performance bottlenecks may be more easily root caused.
