“NFV for Dummies” blog series #1

Do you know what #NFV is?

“NFV for Dummies” blog series #1

Posted on June 30, 2015 by Gary Hamilton I decided it would be a good idea to write a series of blog posts about NFV. Why? Over the last year, I have had to traverse a steep learning curve to understand what NFV is so that I would be in a position where I am comfortable having conversations with service providers and Telcos about it. As I have worked with others in our community, I have recognised the same look of confusion I had when I first started. Secondly, it is clear there is a lot of general confusion around this topic, and I think it is important to provide some clarity about the general concepts. This is a new area for us as a company, so it is OK for there to be some confusion at this point. But that will need to change over…Read More

In my previous blog post I walked you through what happens when EVO:RAIL is being configured for the very first time. Now I want to look at the next important workflow.

A daemon called “VMware Loudmouth” which is available on each of the four nodes that make up and EVO:RAIL as well as the vCenter Server Appliance, is used to “advertise” additional EVO:RAIL appliances on the…Read More

Recently, we’ve updated the Nutanix cluster to vSphere 6 and 4.1.3 — however, no differences have been observed performance since the change.

How to properly license your infrastructure

Always make sure you have the right license for your infrastructure

How to properly license your infrastructure

Making sure you have the right licenses for your infrastructure is hard work. Real hard work. A lot of companies have one or more employees just to make sure they conform to all licensing requirements of their vendors. To make life a little easier I collected the posts we did in the past on this subject. But before you give away licenses based on the things you read here: Always check with your own licensing expert, since licensing can be very complex.

Replacing vCenter Server Certificate Authority…

vSphere 6 makes managing SSL certificates a lot easier than previous releases. It ships with its own Certificate Authority, (VMCA) that issues certificates for all components on your behalf, rather than having to replace each service certificate manually, or relying on self-signed certificates. This new VMCA comes with the Platform Services Controller (PSC) that can be installed as a separate appliance, or embedded within the vCenter Server installation or Appliance. By default, the VMCA will…Read More

The (Un)official VMware VCIX-NV Study Guide

VMware released a new certification for NSX back in October 2014; the VMware Certified Implementation Expert (VCIX-NV). This new certification is the next level for VMware Certified Professional – Network Virtualization (VCP-NV) and validates your skills and your ability to install, configure and administer VMware NSX for vSphere. You can learn more about VCIX-NV here. During the preparations before this exam, I started keeping notes. These notes turned into blog posts and these blog posts turned into complete coverage of the VCIX-NV blueprint. After 3 months, all the objectives were done, I passed the VCIX-NV exam myself and decided to compile everything into an easy to use format. It took a while, but after a lot of text formatting,…Read More

I waffled on some time ago about using proper certificates in your vSphere 5.5 environment. You can read about some of how to do that here. Eric has a nice summary of the steps here. I got a call recently from the customer about a few things and they mentioned some issues with vSphere Replication 5.8. Turns out I’d forgotten about vSphere Replication when I’d gone through the certificate replacement process, as it was done as a PoC. The fix is simple: power off the appliance and power it on again. VMware has a KB for most every situation, including this one – VMware vSphere Replication appliance no longer able to communicate with the VMware vCenter Server after changing the vCenter certificates (2063955). It also helps that I’m a bit…Read More

#VMware #vSphere 5.5 U2 – Resetting the SSO Password

VMware vSphere 5.5 U2 Resetting the SSO Password

In a previous post I talked about deploying custom SSL certs into a vCenter 5.5 environment. As I was working through the update steps, the Certificate Automation Tool kept bombing out when updating the Inventory Service certificate. Neither the client nor I really knew why this was happening, but I had a bit of a hunch that it something to do with SSO credentials. It turned out to be a lucky guess, as I reset the password a few times and the SSL cert tool started working. If you find yourself in this situation, there’s a tool provided with vCenter to reset the SSO password. Here’s a link to the KB article.c:\Program Files\VMware\Infrastructure\VMware\CIS\vmdird>vdcadmintool.exe It’s a fairly straightforward process, but you need to…Read More
