April 4, 2015 / / 0 Comments

Cisco released version 3.0(2c) (release notes here) of its UCS Infrastructure and UCS Manager software (still UCS Mini only) on the 13th of March, and it has 3 new major features: Fibre channel NPV mode, Ethernet switch mode and a HTML5 web interface for UCS Manager.

While the FC NPV and Ethernet switch modes are pretty exciting as well, they are basically just ports from regular UCS.

VMware NSX-v Configuration Maximums

March 17, 2015 / / 0 Comments

VMware usually publishes a Configuration Maximums paper on their products. NSX has quite a bit of specifics that have a limit, but there is not an official configuration maximums paper yet. I hope there will be one soon, but for now I’ve compiled a list of findings from my travels on the interweb.

Most of the figures on NSX 6.1 are confirmed by a paper from PSO, others are from the documentation and real life limits.

VMware Certification Changes

February 3, 2015 / / 0 Comments

When vSphere 6.0 was announced with all its shiny awesome features yesterday, which took the (well deserved) spotlight. There was another announcement that deserves some kind of a spotlight; a new certification system.

VMware has replaced the VMware Certified Advanced Professional (VCAP) with the VMware Certified Implementation Expert (VCIX), which was already in place for Network Virtualization (NSX for vSphere). Like the VCAP certification, VCIX will have an exam focussed on administration and an exam focussed on design.

Here’s an overview of the new system:… Read more
