• VMware vCenter Server 6.0 Availability Guide

    The VMware vCenter Server 6.0 Availability Guide has recently been released by Mohan Potheri, Blair Fritz, and Puneet Gupta. I highly recommend reading this technical white paper as it gives in depth insight on both the vCenter Server 6.0 and the Platform Services Controller availability solutions, configurations, considerations, and recovery options. The various vCenter Server availability options that this technical paper focuses on are VMware vSphere High Availability (HA), VMware vSphere Fault Tolerance (FT), Symantec ApplicationHA, and VM Guest OS Clustering Solutions. It also focuses on Platform Services availability via load balancing and Recovery Options using VMware vSphere Replication and […]

  • vCenter Server 6.0 Log Locations

    vSphere 6.0 has made some significant changes to the logging locations for its contained vCenter and PSC services. Everything has been condensed into a common area of the directory structure and labeled with the service name. In short, it makes a LOT more sense now than it did before.   This is an overview of what the structure looks like now and where to find what you need.   Windows Log Locations   C:\ProgramData\VMware\vCenterServer\logs     vCenter Appliance Log Locations   /var/log/vmware     Note: For the purpose of brevity, all log locations will be referenced from the base logs […]

  • Creating Microsoft CA templates for certificates in vSphere 6.0

    vSphere 6 certificate implementation is much easier than vSphere 5.x thanks to a lot of changes made by VMware. I wrote a previous article on how to replace the Machine SSL certificate, use VMCA as a subordinate CA, and ESXi 6.0 certificate replacement. From my experience, a majority of our customers are using Microsoft for their internal Certificate Authority. One thing I wanted to document for everyone is how to properly create Microsoft CA templates to sign the Certificate Signing Requests (CSRs). There are a few different templates to create, depending on what certificates you are replacing.   Template for […]

  • Passed the VCIX-NV yesterday: tips, thoughts and recap

      VMware Certified Implementation Expert!   Well, I passed the VCIX-NV yesterday after about 2-3 weeks of study. This may have been one of the toughest certification tests that I have taken, but I appreciated the challenge throughout the process. In support, I don’t focus on NSX so I knew I had to put in more work and study time since I didn’t have any hands on experiencing prior to the Hands on Labs or ICM. Three weeks ago I set my mind to obtaining this certificate, so I scheduled the test before touching the product and gave myself just […]

  • NSX Manager SSL certificate replacement with CA

    During my study for the VCIX-NV exam I was writing a post on using the REST API client in Google Chrome when I hit an issue connecting to my NSX Manager via the API call. The error message that I received was below.   Could not get any response This seems to be like an error connecting to https://nsxmanager.vcloud.local/api/2.0/services/ssoconfig. The response status was 0.

  • What is a Platform Services Controller (PSC) in vSphere 6.x

      Platform Services Controller   With vSphere 6.0 introduced, along came the Platform Services Controller, or PSC for short. The best way to think of the PSC is Single Sign-On (SSO) plus more. What is “more” you ask? Let’s start with the deployment options. The PSC can be deployed as either a Windows Server or an Appliance. You can either embedded your PSC or use it as an external PSC (See Software and Hardware Requirements). In my opinion, I would always deploy the PSC externally because it will future proof your environment if your infrastructure is growing. For a list […]
