This article covers the deployment on the vCenter 6.0 VCSA, you will see that this process is radically different from previous processes.
What is NUMA?
Most modern CPU’s, Intel new Nehalem’s and AMD’s veteran Opteron are NUMA architectures. NUMA stands for Non-Uniform Memory Access. Each CPU get assigned its own “local” memory, CPU and memory together form a NUMA node (as shown in the diagram below).
Memory access time can differ due to the memory location relative to a processor, because a CPU can access it own memory faster than remote memory thus creating higher latency if remote memory is required.
This is a very short and sweet article documenting the offline upgrade process from 5.5 to 6.0
In this article I am going to take you through what a Distributed switch or dvSwitch is and how it is used, I will also talk about why backing them up is so important, then show you how to backup by hand and with the help of some PowerShell scripts I have created for you.
It is my experience that resource pools are nearly a four letter word in the virtualization world. Typically I see a look of fear or confusion when I bring up the topic, or I see people using them as folders. Even with some other great resources out there that discuss this topic, a lack of education remains on how resource pools work, and what they do. In this post, I’ll give you my spin on some of the ideals behind a resource pool, and then discuss ways to properly balance resource pools by hand and with the help of some PowerShell scripts I have created for you.
Over the past couple of weeks I have spent some time working with VMware vCloud Director 5.1. I will also be producing multiple other guides for vCloud Director as I use it more over the coming months.
One issue that we have hit a few times was the vCD cell stopped working properly (Multi-cell environment). I could log into the vCD provider and organization portals but the deployment of vApps would run for an abnormally long time and then fail after 20 minutes.
This is a question that I have been asked quite a lot recently. I have found multiple ways to do this but 2 are ones that I have used and find the most suitable.
