Why IT Dashboards Fail
Most dashboards today don't tell the story behind the data.

PowerShell started as a tool to automate Windows servers. It was picked up by VMware (and others) as a platform on which they built their own solutions (PowerCLI and PowerNSX)… but did you know you can use it to configure data center infrastructure, including NX-OS switches, SAN networks, and Cisco UCS?
In the Configuring Data Center Devices with PowerShell video, Mitja Robas described how to do that, and provided source code for all his examples.
You’ll need at least free ipSpace.net subscription to watch the video.
Welcome to another episode of Feature Spotlight. In today's post, we'll quickly cover the loop keyword being introduced in Ansible 2.5.
Everyone knows the with_* syntax in playbooks.
For example:
- name: Test that with_list works with a list
ping:
data: ''
with_list:
- 'Hello World'
- 'Olá Mundo'
In Ansible 2.5, we're introducing loop as a shorter, simpler keyword for playbooks.
Example:
- name: Test that loop works with a manual list
ping:
data: ''
loop:
- 'Hello World'
- 'Olá Mundo'
It's a very minute change, and can easily be overlooked when skimming a playbook! However, when writing many lines of tasks in a playbook, why not save some potential muscle fatigue?
Let's be real, even if a playbook accomplishes a whole lot in 10 lines, that's still ten lines!
All joking aside, we wanted to make things simpler. It's much easier to remember loop than with_items or with_list.
The question after this very well may be, "What happens to with_first_found or with_dict or .... etc, etc, etc?
Well the idea here is to abstract out some of the magic that with_* really is.
Example:
- name: Test that loop works with a list via the list Continue reading
Ethan Banks had a briefing with ReSTNSX, and they demoed their VMware NSX-enhancing platform to him. Have a listen for Ethan's impressions of the demo.

The data center company expects to hit $5 billion in revenue in 2018.
The company's intent-based networking is doing quite well.
Both firms say they are trusted partners of U.S. suppliers and customers.

If you’re running an edge version of Docker on your desktop (Docker for Mac or Docker for Windows Desktop), you can now stand up a single-node Kubernetes cluster with the click of a button. While I’m not a developer, I think this is great news for the millions of developers who have already been using Docker on their Macbook or Windows laptop because they now have a fully compliant Kubernetes cluster at their fingertips without installing any other tools.
Developers using Docker to build containerized applications often build Docker Compose files to deploy them. With the integration of Kubernetes into the Docker product line, some developers may want to leverage their existing Compose files but deploy these applications in Kubernetes. There is, of course, Kompose, but that’s a translation layer which causes you to have two separate artifacts to manage. Is there a way to keep a native Docker-based workflow?
With Docker on the desktop (as well as Docker Enterprise Edition) you can use Docker compose to directly deploy an application onto a Kubernetes cluster.
Here’s how it works:
Let’s assume I have a simple Docker compose file like the one below that describes a three tier Continue reading
Tune in Tomorrow, February 16, 2018 for a FREE online live Spanning-Tree webinar with Keith Bogart.
Deciphering Spanning-Tree Technologies
Starts February 16, 2018 at 10:00 AM (PST) 1:00 PM (EST)
Understanding the logic of 802.1d and how it builds a loop-free “tree” is critical to passing any Cisco certification exam. Presented by INE instructor Keith Bogart (CCIE #4923), this session will take you through that logic so that, given any bridged/switched layer-2 network, you can predict what tree will be formed. Ask questions live with an experienced industry expert!
A primer on the new wireless standard as Aerohive announces the first 802.11ax access point.
Two important changes to the datacenter are happening in the same year—one on the hardware side, another on the software side. And together, they create a force big enough to blow away the clouds, at least over the long haul.
As we covered this year from a datacentric (and even supercomputing) point of view, 2018 is the time for Arm to shine. With a bevy of inroads to commercial markets at the high-end all the way down to the micro-device level, the architecture presents a genuine challenge to the processor establishment. And now, coupled with the biggest trend since …
