On my work, I needed to install ESXi on our Server HP Proliant DL360 G6 server. Going to configure the network, I needed to add adapters to vSwitch but something went wrong and I got the error says to me – “You do not have free adapters to add to vSwitch”.
When in the distant 2001 the VMware ESXi hypervisor appeared on the market, a virtual revolution started that began the end of the era of personal computers with the programs installed on them. This event opened a new era in the development of computers and software – client-server technologies and cloud computing technologies.
This is the third and the last article in the series related to How to build a Cluster based on VMware. In the first article, we saw Cluster Technologies types and understand how to install VMware ESXi, in the second article we look at how to deploy the vCenter Server Appliance (VCSA) 6.5., and now we will look at how to configure VMware HA Cluster.
In 1956, IBM introduced a product that marked the beginning of the computer industry. And the name of this device is HDD.
In the previous article “Building a Cluster based on VMware (part I) we saw Cluster Technologies types and understand how to install VMware ESXi. To create a cluster of ESXi hosts, we need to install vCentre. In this part, we’ll look at how to deploy the vCenter Server Appliance (VCSA) 6.5
As it became known yesterday the company Red Hat announced the acquisition of one of the largest start-ups CoreOS, the amount of the transaction is estimated at $250 million, and its completion is scheduled for March this year.
Red Hat is the world’s leading provider of open source solutions, using a community-based approach to providing reliable and high-performing cloud, virtualization, storage, Linux, and middleware technologies.
To build a cluster, VMware uses from 2x to 32x ESXi servers that are managed using vCenter. To build a cluster, you also need a shared store. It can be implemented with VMware vSAN or with storage support providing access via Fiber Channel, iSCSI or NFS. The storage stores the virtual machine files that are available to all the cluster hosts at the same time. It is due to the overall storage and independence of the virtual machine from the physical platform that rapid migration/recovery of virtual machines is achieved.
No one should be surprised at this point if we mention that Amazon Web Services (AWS) is the main cloud provider in the market, they were and still are one of the main innovators and precursors of cloud services. It’s not going to be a surprise either if we tell you the Microsoft Azure is in second place and growing, but it may surprise you how much Google Cloud is actually growing and that Alibaba Cloud was the second largest growth year-over-year.
Microsoft is continuously releasing new features and options available in their public Azure version, the initial state is usually the “preview” of this feature, which after a period and final touches transforms into General Availability (GA). Within the last couple of weeks, Microsoft released two new features in these two different stages: Adaptive Applications Controls as a public preview and Azure App Service Diagnostics as general availability. These new features come with great benefits for organizations relying on Azure to host critical applications.
When I deployed Bare-Metal servers, I always lose time because of updates. In part of my job, I deploy a lot of physical servers, especially for Microsoft hyperconverged solution. When I install this kind of solution, I have to implement between three to sixteen servers at the same time. The cumulative update installation in Windows Server takes almost 30 minutes. If the servers are not installed at the same time, you can lose a lot of time. This is worst when you install physical servers with a tool like MDT and PXE. You have to copy 1GB in each server and then wait to install it.
To save time, now when I’m deploying physical servers, I update the install.wim file. In this way, the OS is installed with latest updates. In this topic, we’ll see how to update images in WIM files.
