Finally, I’m pround to announce that VCIX6-DCV goal is achived! Previously I passed the Deploy Exam (you can read about it in this post) which for me personally was far more intuitive and effortless. If you are a practitioner person than visioner and designer it would be quite tought to get used to these kind of questions and reasoning. In my opinion there are a few points which I can not agree with and I would be glad to discuss…
It is possible to learn especially about VMware products using just books, official trainings, blogs, etc. However, we believe that the real knowledge is available only by practice and not all could be tested or verified using production environments 🙂 And again, you can test a lot just using Workstation on your notebook (providing it is powerful enough) but these days there are more and more virtual infrastructure component which requires a lot of resources. Furthermore, having real servers and…
To begin the jurney with PowerCLI we need to start from the installation of PowerCLI itself. The installation can be done on a Windows based system, that could be some kind of an administration server. The installation files can be found on this VMware site. There are a few versions available, they are released asynchronously with vSphere and the version numbers do not exactly correspond to vSphere versions. The most recent version is 6.5 whilst there are other like 6.3,…
Before we start talking about NetFlow configuration on VMware vSphere let’s back to basics and review protocol itself. NetFlow was originally developed by Cisco and has become a reasonably standard mechanism to perform network analysis. NetFlow collect network traffic statistics on designated interfaces. Commonly used in the physical world to help gain visibility into traffic and understanding just who is sending what and to where. NetFlow comes in a variety of versions, from v1 to v10. VMware uses the IPFIX…
Before we start I would like to describe main motivation to write this article which is quite simple – to gather in one place all basic theoretical background about iscsi protocol and best practices at its implementation on vSphere platform with special consideration about potential performance tuning tips & tricks . This is first part of the series where We (I’m counting on readers participation) try to gather and verify all this “magical” parameters often treated as myths by…
You can observe some random and intermittent loss of connection to ESXi 6.0 host running on Dell servers (both Rack and Blade). It’s caused by a bug with Cisco Discovery Protocol /Link Layer Discovery Protocol. It can be also seen while generating VMware support log bundle because during this process these protocol are also used to include information about the network. What are these protocols for? Both of them perform similar roles in the local area network. They are…
