If you happen to fly frequently with Delta Airlines, you might enjoy my recent finding. I just flew back from my vacation yesterday on a Delta flight from Atlanta to San Jose (SJC) and found an easy way to get free wifi for any of your iOS devices.
Note, this might work for all devices including your laptop but I only tried it from my iPhone and iPad.
For the NetShelf Setup, make sure you allocate a minimum of 3 IPs (floating, controller 1 & controller 2) for the data network or a total of 6 IPs if you plan to separate the management and data networks. The actual setup is very simple and takes only 2-3 minutes.

Datrium DVX initial setup finished!
To access the Datrium Graphical User Interface:
1) If you are already logged in vSphere Web Client, log out.
2) Log back into the vSphere Web Client.
3) Click the Datrium icon in the Web Client home page.
To complete the DVX setup in the GUI:
1) Click on 'Configure DVX' for additional settings.
2) Click on 'Configure hosts' to add hosts to the DVX.
The NetShelf is now set up and ready to be used in under 3 minutes.
In the next post, I will go over adding hosts to the Datrium DVX.
VM Monitoring comes with three different options. By default it is set to Disabled but you can enable either VM Monitoring Only or VM and Application Monitoring.
In either case, the VM uses VMware Tools to identify the state of the VM and its application and then reboot the VM if necessary.
What is the difference between VM Monitoring Only and VM and Application Monitoring?
VM Monitoring Only utilizes VMware Tools to check regularly for heartbeats and I/O activity from the VMware Tools process. Depending on the Monitoring Sensitivity setting, vSphere HA will know how often to look for heartbeats and how often the VM should reboot.
VM and Application Monitoring also utilizes VMware Tools and can monitor the VM just like the VM Monitoring Only setting but it can also monitor the application, running on the VM. In order to enable Application Monitoring the application has to support VMware Application Monitoring or use the appropriate SDK.
At a minimum it is best practice to enable VM Monitoring Only to ensure maximum availability for your most important VMs. Note, this setting can be adjusted per VM via VM Overrides in the Cluster Settings
For the readers who aren’t familiar with the Top vBlog competition, it is all about best content and frequency of content. Last year I wasn’t even on the list to be voted for. However, this year I made it on the list and I’m ranked 72 out of 321 blogs.
Not bad at all. I’m super excited and thankful for everyone who took the time to vote for me and my blog. You are the reason I’m sharing my stories and my knowledge.
A special thank you to Eric Siebert, who made this happen!
