Near-Line Storage For A Variable FIFO/LIFO Brain
Posted in Open Source, Technology, Virtualization on Mar 22nd, 2015
After fighting a bit with EMC ScaleIO to setup a demo on VMware, I decided there has to be an easier and more cost-effective way to implement fault-tolerant software defined storage for VMware vSphere using existing open source packages. I have to admit I’m a fan of RHEL based solutions, so a quick Google search […]

I recently posted the following in a forum topic comparing VMware ESXi and Microsoft Hyper-V hypervisors and thought I’d slap it here for posterity: Hyper-V does not run as a service on top of Windows – which would be a Type 2 hypervisor, rather it is a Type 1 hypervisor (just like ESXi) that runs […]

If you’re like me and you sometimes do things rather hastily in your home lab (NEVER IN PRODUCTION THOUGH), then you might have found yourself with an orphaned vCenter Server in your SCVMM 2012 console after moving away from VMware’s vSphere hypervisor (for whatever valid reason – choose from many). Well, you’re in luck – […]

I’m using a CentOS 6 box for HA NFS storage behind a cluster of VMware ESXi boxes. I want to make sure those ESXi hosts aren’t fighting over a single 1Gbps Ethernet interface. Bonding 6 interfaces (3 x Intel Pro Dual-NICs) should do the trick… On 3750x: Configure switch ports (for me, that’s gi1/0/25 – […]

This is a highly abbreviated how-to guide to build your own VMware vSphere lab very quickly: Acquire/build a computer with more than 16GB of RAM that will allow virtualization pass-thru (if you don’t already know, then research this before you proceed) Install your choice of operating system and virtualization package (I use VirtualBox on CentOS) […]

To renew the trial status of an existing ESXi 5.1 install: Perform a fresh install of ESXi 5.1 in a virtual machine (choose your poison for hypervisor – I use VirtualBox) Copy the /etc/vmware/license.cfg and /etc/vmware/vmware.lic files or contents of the files from the fresh install you just performed to the existing ESXi 5.1 host […]

In the course of running my home lab on the latest VMware hypervisor (ESXi 5.1.0 799733), I thought it prudent to evaluate the install and function of the VMware Tools package for a CentOS 6.3 guest. Here’s how I got her done: Add the VMware GPG keys (optional, but a good idea): rpm –import http://packages.vmware.com/tools/keys/VMWARE-PACKAGING-GPG-DSA-KEY.pub […]
