The $449M Price VMware Paid for VeloCloud Could Be Misleading
IHS Markit also reported drops in SD-WAN revenue for Huawei and InfoVista, but these could simply be reflections of quarterly variations in contracts.

Juniper vQFX10K on ESXi 6.5
A quick and dirty post on running the Juniper vQFX on VMWare ESXi.
You might be wondering why ESXi seeing as we’re all cloudy types. ESXi is purely a case of laziness. Each server in my control has ESXi 6.5 installed. This becomes tin management at the most basic level.
Part of my home network has a DMZ which has several public IP addresses and I expose systems and VNFs externally over the internet. More recently thanks to the IP fabric craze, part of what I’m exploring is easy integration and feature enhancement on Juniper vQFX instances. Two choices exist:
- Install vQFX on servers with KVM
- Install on ESXi
I went for the easy ground (because why make it harder than it has to be?) Turns out, it wasn’t as straight forward as it should be, although not difficult. Just a niggle.
Installation Process
Grab yourself the RE and PFE images from the Juniper download site:
https://www.juniper.net/support/downloads/?p=vqfxeval I Grabbed the 18.1 RE and the 17.4 PFE image.
Next, extract the two
.vmdkfiles from the
.boxfiles. You can use the trusty tar tool to extract the files required. Below are two files Continue reading
Command Module Deep Dive for Networks
Enterprise customers often ask the Ansible Network team about the most common use cases for network automation. For this blog post I want to talk about one of the most used (and most versatile) set of network modules: the command modules. The command modules let you run networking commands with Ansible, the same way a network engineer would type them on the command line. With Ansible, though, the output doesn’t just fly by the terminal window to be lost forever; it can be stored and used in subsequent tasks. It can also be captured in variables, parsed for use by other tasks, and stored in host variables for future reference.
Today we’re going to cover basic use of the network command modules, including retaining command output with the register parameter. We’ll also cover scaling to multiple network devices with hostvars and adding conditional requirements with the wait_for parameter and three related parameters: interval, retries, and match. The takeaway from this blog post is that any repeatable network operations task can be automated. Ansible is more than configuration management, it allows network operators the freedom to decouple themselves from routine tasks and save themselves time.
There are command modules Continue reading
PQ 150: HCI Networking With Big Switch’s Big Cloud Fabric (Sponsored)
One promise of hyperconverged infrastructure (HCI) is ease of management. Break down the silos, put all the components into a unified whole displayed on a single pane of glass, and voila! Apps are served.
But networking hasn t been integrated as effectively into HCI as the other components of the IT stack. Networking, even in an HCI world, tends be difficult. And with the dynamic needs of HCI, networking just isn’t keeping up.
The days of standing up the network and letting it run are past, because a best effort, rough approximation of how the network should behave isn t something you have to settle for anymore.
Discussing integration of HCI with networking is Big Switch Networks, our sponsor for today s Priority Queue. Prashant Gandhi, Chief Product Officer at Big Switch, is our guest.
We talk about why “best-effort” networking isn’t suited for HCI, and look at HCI-specific operational issues and use cases including container networking and multi-tenancy.
