  • Pure ELK Dashboards

    Previously I blogged about getting PureELK installed with Docker in just a couple of minutes. After setting up your intitial array’s you may ask what is next? Loading a preconfigured PureELK Dashboard Click load saved dashboard and select one of the Pure Storage dashboards. Remember there is a 2nd page page of Dashboards. Pure Main […]

  • Dynamic Cluster Pooling

    Dynamic Cluster Pooling is an idea that Kevin Miller ( @captainstorage) and I came up with one day while we were just rapping out some ideas on the whiteboard. It is an incomplete idea, but may have the beginnings of something useful. The idea is that clusters can be dynamically sized depending on expected workload. […]

  • All out of HA Slots

    A few weeks a go I was moving a customer from an old set of ESX servers (not HA clustered) to a new infrastructure of Clustered ESX hosts. After building, testing and verifying the hosts we started moving the VM’s. It became apparent after a little while there were some resource issues. After just a […]

  • Operational Readiness

    One thing I am thinking about due to the VCDX application is operational readiness. What does it mean to pronounce this project or solution good-to-go? In my world it would be to test that each feature does exactly what it should be doing. Most commonly this will be failover testing, but could reach into any […]

  • 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 – User Profile Options

    All the technology and gadgets for managing desktops are worthless if your users complain about their experience with the desktop. Something I learned administering Citrix Presentation Server. Differing methods exist to keep the technical presentation of the desktop usable, for example the mouse being in sync and the right pixels show the right colors. What […]

  • Random Half Thoughts While Driving

    So I often have epiphany teasers while driving long distances or stuck in traffic. I call them teasers because they are never fully developed ideas and often disappear into thoughts about passing cars, or yelling at the person on their cell phone going 15 MPH taking up 2 lanes. Here is some I was able to save today (VMware […]

  • 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) […]

  • iSCSI Connections on EqualLogic PS Series

    Equallogic PS Series Design Considerations VMware vSphere introduces support for multipathing for iSCSI. Equallogic released a recommended configuration for using MPIO with iSCSI.   I have a few observations after working with MPIO and iSCSI. The main lesson is know the capabilities of the storage before you go trying to see how man paths you can […]

  • New VMware KB – zeroedthick or eagerzeroedthick

    Due to the performance hit while zeroing mentioned in the Thin Provisioning Performance white paper this article in the VMware knowledge base could be of some good use. I would suggest using eagerzeroedthick for any high IO tier 1 type of Virtual Machine. This can be done when creating the VMDK from the GUI by […]
