Virtualization

Introduction I have been working with virtualization and container systems over a decade and a half at this point. My first experiences with putting multiple machines on a single host was likely OpenVZ. I have worked with systems such as OpenVZ, Xen, KVM, Docker, VMware ESXi, and their management systems such as vCenter, Proxmox VE, Nutanix Prism, and Xenserver to one level or another. I have also ran storage arrays from Netapp, Pure, EMC, HPE, and IBM and hyper-converged solutions such as Ceph and Nutanix AVS. I have designed and built enterprise storage and virtualization solutions for over a decade… Read more: Proxmox VE Storage Integration: A Business Case

I was writing the first of my TrueNAS API Integration posts when I wrote a statement that hit me: “It is critically important that any API keys in files have absolute minimum permissions. You are storing a password to your storage system on a server. I’ll say that I feel like this integration is taken for granted in a lot of systems, even at an enterprise level. An increase in the surface area available is unavoidable when automating. A robust set of user roles as above is a fantastic idea. I personally would strongly advise 600 permissions on the API key file… Read more: Less is more; Do you really need that feature?

I)Introduction In part One, the fundamentals and theory behind network configuration were covered. In part two, these theories will get put to use. This section will demonstrate the structure of switching within VMWare and Proxmox then configure them to form a usable network. Having local or KVM access to these systems is recommended in case of a configuration error that needs rolled back, especially if it involves the management interface(s.) Switching is varied, so this documentation will not cover it other than to say what needs to be done on the other side. II)What Does the Switching Configuration Look Like?Proxmox… Read more: VMware vs Proxmox VE Networking PT II

I)Introduction This document is part of a three (ED:four) part series that will cover the basics of configuring networking on Proxmox similar to basic configurations within VMware. The intended audience is someone with limited Linux skill who is transitioning away from VMware or someone who is new to virtualization and needs to understand what a basic network architecture for connecting a virtualized server to a network looks like. It is my opinion that while different, the network configuration capabilities of Proxmox within its GUI are excellent. Not only that, but there is the added benefit of being able to work… Read more: VMware vs Proxmox VE Networking PT I

I)Introduction This is something that I’ve been thinking about since Broadcom bought VMware and injected a lot of uncertainty in to the world. I’ve personally seen what a renewal in the Broadcom Era looks like and it isn’t something that is compatible with the business practices or budgets of many organizations. My focus at this point is in the native, on premises hypervisor and base level management. To put it in product terms, vSphere and ESXi. There are a huge amount of businesses that use VMware without bolt ons, which is one of the reasons why the new SKU options… Read more: Hypervisor Bake Off
