VMware NSX – Installation

One of the good guys, Hany Michael over at, has made a few videos showing the installation ease of VMware NSX. Unfortunately us normal peasant people do not have access to NSX yet, but you can see how the installation goes. Check these out:


Deploying the NSX vAppliance

Deploying the NSX Controllers

Preparing ESXi hosts

Configuring a Logical vSwitch

VMware NSX – Distributed Services

This article is number two of a series about the upcoming network virtualization spree, specifically the one coming from VMware. Check out the other articles.

Traditional network services have evolved over the last years. Introducing more advanced firewalling, loadbalancing and remote access services. Typically, datacenter networks architecture these days look somewhat look this:

VMware - Traditional Services

The routers can be virtualized inside a physical box, using either VRFs or vendor proprietary router virtual routers, such as Cisco VDC. However, the external and internal firewalls are usually separate monolithic hardware firewalls, which puts a large dent into the network budget.

Nexus 5500: Changing Unified Ports on expansion module without reload

When you need to only the change the unified ports inside an expansion slot of a Nexus 5500, you do not have to reload the entire switch to activate the unified port changes. You can simply restart only the module like this:

nx5548up-a# config t
nx5548up-a(config)# slot 2
nx5548up-a(config-slot)# port 1-16 type fc
nx5548up-a(config-slot)# end
nx5548up-a# copy run start
nx5548up-a# poweroff module 2
nx5548up-a# no poweroff module 2

VMware NSX – General

This article is number one of a series about the upcoming network virtualization spree, specifically the one coming from VMware.

I spent 14 to 17 October at VMworld 2013 in Barcelona, basically getting my mind blown by the futuristic possibilities of network flexibility. Things are changing for the network, flattening the entire stack, distributing network services throughout the virtual network (instead of the monolithic central hardware), lowering network costs and making it more flexible and simple to manage.

In this post, I will go over the basics of the components that are used to form the VMware NSX virtual network.… Read more

Exchange 2010 SP2 – New-MailboxExportRequest not found

When I read about the new powershell cmdlet New-MailboxExportRequest, I was very excited about it (because I was planning a migration for a few mailboxes).

After having to manually install several required hotfixes (some of which were related to .NET 2.0 (what the hell MS?)) and running through the SP2 upgrade process three times..I was much less excited: whatever I tried, the cmdlet that triggered me to upgrade, was nowhere to be found.

Turns out, the cmdlet does not appear to exist in the powershell-sphere, if you do not have the proper permissions (must be easier to hide commands … Read more

Changing ESXi 5.1 Service Console VLAN ID via PowerCLI

Today I had the need to remove the VLAN ID from 60 ESXi 5.1 hosts. Instead of doing it 60 times manually through the KVM, PowerCLI was enlisted for the job. That wasn’t the hard part, the one-liner is quite simple..For those interested:

As mentioned, this wasn’t the hard part. It appears that vSphere 5.1 has a (pretty cool!) new feature that checks whether … Read more

UCS Explained in video

Brad Hedlund‘s blog is one of my favorite sources of excellent UCS (and other general) material. I just found the exceptional UCS videos, which deserved a re-share.

Part 1 – The Physical Architecture of UCS

In this video we take a look at the physical network architecture of Cisco UCS and incorporate the new capability of connecting both blade and rack mount servers to UCS Manager.

Part 2 – Infrastructure Virtualization & Logical Architecture

Here we look at how Cisco UCS virtualizes every significant component of the physical architecture; switches, cables, adapters, and servers. Then we look at how … Read more
