Folks release recently is the Security of the VMware vSphere Hypervisor.
I decided to take the HOL-SDC-1305 lab but only module four tonight. Why only module four? Well, it’s the one all about vCenter Server Heartbeat.
If you have not taken a VMware lab I would highly recommend it as you’ll gain the proper topic knowledge and you’ll get to do some great hands on lab work at the same time.
HOL-SDC-1305 (Module 4) didn’t disappoint me, it was straight to the point, went through the key areas, and was a great overview of the product.
I wanted to see more about requirements, design, and any constraints. However these items were outside the scope of this lab so I can’t really hold it against it.
I attached a quick screen shot of the lab for your enjoyment!
Note – Everyone has access to the VMware Hands on Labs, and it’s FREE to all.

vExpert 2014 applications are open! I’ve been part of this program since inception, it’s a great community of technical folks who enjoy spreading the word of virtualization!
Please feel free to submit and if you need some tips please post up!
Think you’re one of the best? Have you been supporting and contributing to the VMware Community? Have you excelled and completed the latest certification & accreditation training? If Yes then I would encourage you to apply for the 2014 vExpert Program! http://bit.ly/MtDKff
Each year, we bring together in the vExpert Program the people who have made some of the most important contributions to the VMware community. These are the bloggers, book authors, VMUG leaders, speakers, tool builders, community leaders and general enthusiasts. They work as IT admins and architects for VMware customers, they act as trusted advisors and implementers for VMware partners or as independent consultants, and some work for VMware itself. All of them have the passion and enthusiasm for technology and applying technology to solve problems. They have contributed to the success of us all by sharing their knowledge and expertise over their days, nights, and weekends.
vExperts who participate in the program have access to private betas, free licenses, early access briefings, exclusive events, free access to VMworld conference materials online, and other opportunities to interact with VMware product teams. They also get access to a private community and networking opportunities.
VPN (VMware Partner Network) Path
The VPN Path is for YOU, members of our partner companies, who lead with passion and by example, who are committed to continuous learning through accreditations and certifications and to making their technical knowledge and expertise available to many. This can take shape of event participation, video, IP generation, as well as public speaking engagements. A VMware employee reference is required for VPN Path candidates.
I’ve been lucky enough to make the past 6 VMworlds and to date this year was my favorite.
Here are some quick notes that a few colleges and I put together, I hope you enjoy it!

NSX and Network Virtualization:
-NSX does for the network what ESX did for compute: abstract, pool, make automation much easier. This is about agility and simplicity, and services, not the physical medium of the network.
-NSX is a bridging technology just like ESX. It sits on top of the physical Network and doesn’t replace it… just extends and makes it better.

I recently did some exploring on my home lab around datastore heatbeats and came up with the following notes around how to determine which ones are active, how to change the defaults, and why vCenter Server might now choose a datastore.
vCenter Server selects a preferred set of datastores for heartbeating. This selection is made to maximize the
number of hosts that have access to a heartbeating datastore and minimize the likelihood that the datastores
are backed by the same storage array or NFS server. To replace a selected datastore, use the Cluster Settings
dialog box of the vSphere Client to specify the heartbeating datastores. The Datastore Heartbeating tab lets
you specify alternative datastores. Only datastores mounted by at least two hosts are available. You can also
see which datastores vSphere HA has selected for use by viewing the Heartbeat Datastores tab of the HA
Cluster Status dialog box.
Only use these settings if you want to override the default vCenter Server Choice
Here is an article around why it might not choose a Datastore…
User-Preferred Datastore is Not Chosen
vCenter Server might not choose a datastore that you specify as a preference for vSphere HA storage heartbeating.
You can specify the datastores preferred for storage heartbeating, and based on this preference, vCenter Server determines the final set of datastores to use. However, vCenter Server might not choose the datastores that you specify.
This problem can occur in the following cases:
■ The specified number of datastores is more than is required. vCenter Server chooses the optimal number of required datastores out of the stated user preference and ignores the rest.
■ A specified datastore is not optimal for host accessibility and storage backing redundancy. More specifically, the datastore might not be chosen if it is accessible to only a small set of hosts in the cluster. A datastore also might not be chosen if it is on the same LUN or the same NFS server as datastores that vCenter Server has already chosen.
■ A specified datastore is inaccessible because of storage failures, for example, storage array all paths down or permanent device loss.
■ If the cluster contains a network partition, or if a host is unreachable or isolated, the host continues to use the existing heartbeat datastores even if the user preferences change.
Verify that all the hosts in the cluster are reachable and have the vSphere HA agent running.
Also, ensure that the specified datastores are accessible to most, if not all, hosts in the cluster and that the datastores are on different LUNs or NFS servers.
I’ve attended every VMworld since 2008 and over the years I can’t tell you how many times I’ve been asked by attendees how to find their way around or when does something open or close.
This year *BING* it hit me and I took some time to put together a customer guide combining all the good information around – Registration, HOL, Meals, Shuttle, etc…
Of course I would recommend you use the official VMworld websites, apps, etc. but if you want a simple an easy way to find information then this may work for you too.
Click on the PIC below to download the ‘Unauthorized vmexplorer guide’!
Check out this great video around how VMware Hands-on Labs can enable you to do more with VMware products.
It really goes over the finer points on how customers can logon to HOL, check out our products/technologies, and then deliver them into your environment.
BTW — Great job Doug Baer, oops… I mean Trevor J
Over these past years I’ve collected a bunch of lanyards, buttons and stuff. Mainly I collected them as an end user, VMUG leader, and now as a VMware employee. At one point my car had a custom VM license plate. I hung on to all this stuff because I really liked it or wanted to remember good times. However everything was just starting to pile up and collect dust. This past weekend I made a choice to not box them up or toss them away but do something creative which included a power staple gun. Attached to this post is my creation, they went from being a dust pile to a work of art.
It’s pretty simple to make…
You need –
- One Rectangle Cork board (I found my at Wal-Mart)
- Power Staple Gun
- Enough lanyards to create a layout
- Start in the middle, place the first one on an angle, staple them to the back side, and cut off the excess
- Working out from the middle I used two straws as a spacer and placed the next lanyard on an angle. Make sure its square as any deviation will show
- From there repeat, adjust, staple, and cut
If you have a plate you want to mount, center it, and I just used push pins to hold it up
Enjoy and Good times!
