VMware SDDC Technical Whiteboard

One of my favorite things to do is whiteboard. In my line of work, the whiteboard allows me to tell a story…one that can be broad in coverage, yet tuned on-the-fly to best align with the needs of the audience. It started as a “cloud” whiteboard back when vCloud Director (vCD) was released and the first vCloud Suite offering was announced. The first storylines were all about VMware’s cloud and management framework and leveraging vCD to align with a set of industry-accepted characteristics that defined “cloud”. There have been several iterations over time as new technologies (and acquisitions) came to fruition, with an evolving storyline to highlight modern challenges and the transformative nature of the Software-Defined Datacenter.

The whiteboard has been delivered on your standard everyday office whiteboard, table-tops, glass walls, flip charts, notepads, napkins, and electronically via powerpoint, iPad, and digital sketch pads. Regardless of delivery medium, I have found the whiteboard to be the most effective means of articulating the often-confusing details and associated benefits of the Software-Defined Datacenter at any level of depth…and without yawn-generating, ADD-invoking death by powerpoint.

My most recent iteration of the SDDC whiteboard doubles as field and partner enablement, so I had to put a little more thought into the storyline to ensure it closely resembles how customers have typically leveraged vSphere, NSX, VSAN, and the vRealize Suite evolve their existing datacenters to quickly build and gain the benefits of SDDC.…

Scaling VSAN: Adding a New VSAN Host

In my previous post, VMware VSAN Meets EZLAB, I highlighted the implementation of VSAN into my vCloud lab. At the time of writing, 1 of 4 my vSphere hosts was down for maintenance and was not added to the VSAN cluster. Now that it’s back online, I thought I would share the experience of adding a new VSAN host…and another 2.25TB of capacity.

Here’s a “before” shot — 3 hosts configured with 6.13TB total capacity…

Step 1: Add the host to the existing VSAN cluster: I’m pretty sure I don’t have to review how this is done. Once added, configure all settings to match the other hosts in the cluster…in my setup I’m using a dedicated pNIC and vmkernel port (vmk1) for all storage traffic.

Adding new host to the vSphere cluster

The local storage of the new host, a Dell R610 box, is configured identically to the other
three — 1 x 256GB SSD + 3 x 750GB SATA drives. And since it is
identical, that also means I had to deal with the fact that the PERC 6/i
controller does not support JBOD. So, I stepped through the work-around to identify the SSD as such…

before…the SSD show up as “Non-SSD”


“esxcli storage…” command executed on host



the SSD is now recognized as an SSD drive


Step 2: Enable VSAN Service on the vmk port…

Configure vmk for VSAN traffic

Step 3: Disk Management…

Since my VSAN cluster is configured to “Manual” mode, adding the new host’s disks to the cluster takes an additional step.…

VMware VSAN meets EZLAB

Let me just get this out of the way – I’m a HUGE fan of VSAN (aka VMware Virtual SAN). I was first in line to drink the kool-aid when VSAN was nothing but a “what if…?”. Fast forward to the present — VSAN beta (refresh) is backing my entire lab. I’m tweaking, testing, breaking (learning), and sharing my thoughts on VSAN’s capabilities, performance, and benefits ahead of the official launch. This is all in good order because even the beta has exceeded my expectations in what VMware would ship as a 1.0 product.

I can write page after page about the ins-and-outs of VSAN, but fortunately several very respected individuals have already done so. For starters, Duncan Epping at yellow-bricks.com not only is a massive contributor to the cause, but has also put together a nice list of VSAN resources from around the web that is a must-see. But lets face it, if you’re tracking VSAN you’ve probably already been there, done that 🙂  So for this post, I’m going to focus instead on my VSAN home lab build and experiences thus far. I’ve shared several preliminary stats on twitter (here, here, and here) ahead of any tweaking and will be sure to post additional results as I play with things a bit more.…

VMware SDDC / vCloud Suite Whiteboard

I recently had the opportunity to brief several dozen VMware Public Sector (US-Fed / SLED) partners in anticipation of the vCloud Automation Center (vCAC) 6.0 GA release. While most of the day focused on vCAC, I spent about an hour or so delivering an updated version of my SDDC Whiteboard brief to help set the stage for vCAC.

The whiteboard provides an overview of VMware’s SDDC / vCloud vision — starting from the foundation (i.e. vSphere) and capped off by the cloud automation layer (vCAC)…and all the loveliness in between.

This is a presentation I do often, but no two are the same. If you’ve got 45ish minutes to spare, please do and feel free to provide some feedback!
