VMware NSX on a FlexPod (with dynamic routing)

Cisco has made it clear that there will be no validated design for a FlexPod with VMware NSX running as the virtual network and there will be no trifecta vendor support for the entire platform. This does not mean you’re completely barred from using it though. To be able to make use of the best of both worlds, I’ve been working to create a design that uses FlexPod as the rock solid foundation and offer the networking flexibility that VMware NSX offers. The goal is to not change the FlexPod design so that it will still be certified for support.… Read more

VMware vCenter 5.5 Update 2 released!

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

Cisco releases Nexus 1000v 3.1 with an Update Manager!

Cisco has released version 3.1 of its virtualised switch (available for download here). It comes with increased scalability and resiliency, but one very cool thing stood out for me: the Virtual Switch Update Manager or VSUM.

The VSUM is not the only cool improvement on the virtual switch, here’s an overview of changes:

  • Scale
    • Increased Scalability (Advanced Edition) – More than doubles the scale from the previous release. The virtual switch now supports 250 hosts/servers per switch with 10,000 ports per switch. In addition it supports 4094 active VLANs and 16 million VXLAN (6144 active VXLANs) per switch across

VMware VXLAN Host Preparation: Add virtual NIC: Unknown error

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

VMware VCP Required Recertification

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: Configuring Load Balancing

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

Design Guide – Deploying VMware NSX with Cisco UCS and Nexus 7000

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
