  • Finishing some setup for my Unifi Dream Machine Pro

    I wanted a better home router. During the learning from home phase of the 2020 pandemic I learned I could not have advanced security features of the USG (Unifi Security Gateway) turned on and get sufficient bandwidth for 3 Kids and myself to stream and zoom. So I wanted an upgrade. I went with the […]

  • Some NSX-T Things I learned

    The last few months I have done a lot of work with NSX-T. I have not done so much networking since my CCNA days. I wanted to share a couple of things that were really helpful I found out on the web. I was using NSX-T 2.4.2 and sometimes some troubleshooting guides were not very […]

  • Lead the Transfomation

    Speaking with customers everyday the most common thing I see the infrastructure teams struggle with is how do we get from X to Z. We are virtualizing first. Evaluating tier 1 apps as VM’s. Migrating non-essential services to the cloud. As an overall strategy how do I get from what I have, to where I […]

  • vSphere Metro Stretched Clusters – Some Info/Links

    A lot of questions lately about vSphere Clusters across distance. I really need to learn for myself so I collected some good links. Make sure you understand what “Only Non-uniform host access configuration is supported” means. Someone correct me if I have this wrong but your device that enables the distributed virtual storage needs to […]

  • Trunks – Dell Power Connect and Cisco

    I recently needed to install a stack of Dell 6224 Power Connect switches. The core of the network was actually a Cisco 3560 (no G). While there are already posts existing from Scott Lowe about using the “General” mode to keep VLAN 1 untagged and also have other VLAN’s tagged. Dell’s General mode traditionally works […]

  • Firewalls are not Routers

    I am no network super-genius but I do enough with networking to be able to get by. Two common mistakes I find many times are flat networks and firewalls as the default gateway. A flat network is when generally switches are connected to one another without any configuration. There is one broadcast domain which means […]

  • Ask Good Questions

    This happened a long time ago. I arrived at a customer site to install View Desktop Manager (may have been version 2). This was before any cool VDI sizing tools like Liquidware Labs. I am installing ESX and VDM I casually ask, “What apps will you be running on this install?” The answer was, “Oh, […]

  • VMware View and Xsigo

    *Disclaimer – I work for a Xsigo and VMware partner. I was in the VMware View Design and Best practices class a couple weeks ago. Much of the class is built on the VMware View Reference Architecture. The picture below is from that PDF. It really struck me how many IO connections (Network or Storage) […]

  • ESX Commands: esxcfg-vswif

    The esxcfg-vswif command allows you to create and modify Service Console ports and their IP information. Many times I have to change stuff after the install process is complete and the only place is via the direct service console because network communication is not possible. This usually happens when the network team changes a vlan […]

  • ESX Commands – esxcfg-firewall

    I have really forgot to keep up on my VCDX study path. So today a quick tidbit on the esxcfg-firewall command.Many of us today will use the vCenter Client to change firewall ports on the ESX. One instance where I exclusively mess with the firewall from the command line using esxcfg-firewall is when I install […]
