VMware has released vCenter 5.5 Update 2 today. Most of the updates are basic product support updates, like support for Microsoft SQL Server 2014 and removing support for IBM DB2. There are a bunch of bug fixes in there as well. For the full list, check here.

One particular change was a bit buried in the release notes and was not mentioned in the blog post, which tries to say it’s not a major change. However, for VMware administrators, this might be the most important change in Update 2 and the reason they will upgrade; In Update 2, you … Read more


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! ­čśë

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.┬á
  • Use DVS network shares to prioritise your traffic.
  • Make sure your MTU values are set properly.

It’s a very good … Read more


One of the good guys, Hany Michael over at hypervizor.com, 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:

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.

As we move … Read more
