When working on a large project, I tend to make overview sheets for myself to track progress. My CCIE Datacenter project is no difference. I’ve been asked to share my CCIE Datacenter progress excel sheet a bunch of times now, so I figured I’d put it here: CCIE DC Progress Sheet

 

It has been put together with inspiration from other sheets and it assumes you have an INE subscription for their excellent videos.

During the implemention of a private cloud solution using vSphere and vCloud Director, there was the need to reinstall the ESXi hosts with a custom ISO. At that point the vSphere platform was already deployed, vShield Manager and vCloud Director were running and integrated with each other, and the VXLAN preparations (transport VLAN added, vmknics were deployed and active and the segment networks config) we’re already done. VXLAN Network deployment was working and the vShield Manager and vCloud Director were happy with the vSphere environment.

 

After the ESXi host reinstall, it got its Host Profile back and was added … Read more


Up until now the VCP program of VMware has been a “VCP for life” type of deal. You do the exam and get the VCP sticker without having to follow up, unlike other certification programs like the Cisco certifications.

VMware has just announced a change to their certification program which requires current VCP holders to recertify every two years. After the continuing improvements to the VMware certification program, like splitting up the technologies into general, cloud and mobile tracks, you now have to prove yourself worthy of the VCP title every two years.

This new policy gives you three options … Read more


VMware NSX integrates networking into the virtual world. It also brings networking services to the in a distributed and much simpler fashion. One of those network services is load balancing. Using NSX, you can create virtual IP addresses which routes incoming network traffic to multiple real servers.

It works just like your regular hardware load balancer (F5, A10 Networks, etc), but in a distributed way and grouped by real servers on your computing hardware.

Making these network services virtual, means being able to deploy it very rapidly and easy. So easy, you can create a web load balancing cluster in … Read more


VMware has released a design guide for a network with NSX, Cisco Nexus 7000 and Cisco UCS computing. Perhaps it’s a small glueing attempt from VMware to Cisco, maybe it’s nothing. The thing is, I’m really happy about this design guide, there’ll be a FlexPod for NSX yet! 😉

Read it here: http://www.vmware.com/files/pdf/products/nsx/vmware-nsx-on-cisco-n7kucs-design-guide.pdf

The document outlines a few important tips:

  • Use separate links for the routing between NSX and the Nexus switches. As you don’t want to route over vPC. 
  • Use DVS network shares to prioritise your traffic.
  • Make sure your MTU values are set properly.

It’s a very good … Read more


Guacamole is a gateway application described for HTML5 Clientless Remote Desktop, and I absolutely fell in love with it recently. Working in the field, you constantly come across networks where you get limited access to the outside world, where the life’s goal of the firewall outgoing policies is to make your life a living hell when you need to get something from your own network. </rant>

I’ve tried RDP Gateways (not really platform portable), SSL VPNs, Secure VNC, and a bunch more, but none seemed to stuck. None was really usable on all platforms I want access from (Mac, … Read more


The UCS Central appliance is on it’s way to be a proper centralized management platform for multiple UCS domains, but it’s not quite there yet. There are little simple things missing, such as custom SSL certificates. I had to get UCS Central using a proper SSL certificate the other day and couldn’t really find anything on how to do it. After figuring out how to do it, I decided to document it here!

I’m not getting into how you can generate a SSL private key, there are plenty of other tutorials covering those things. You’ve got two options; generate the … Read more
