vSphere: Migrate Management Network from dvSwitch to vStandard Switch

I recently found a feature that allows you to quickly migrate the management network from a Distributed Virtual Switch (dvSwitch) to a vStandard Switch (vSwitch).  It’s really simple actually.  Just log on to a host physically or via iLO, not through the vSphere Client, and select “Restore Standard Switch”.

vSphere: Move Hosts to New vCenter Server

host migrationI recently set out to recreate my vCenter installation since I was still running on Windows Server 2003 R2 64-bit and wanted to the set it up on Windows Server 2008 R2.  The problem here was that my Management Network was attached to a dvSwitch (Distributed Virtual Switch).  I’ll briefly outline the process of how I removed each host (3 hosts in total) from vCenter, attaching the host to the brand new vCenter installation with only about 10 minutes total virtual machine (VM) downtime.  This can actually be done with no downtime if planned properly and aware of the possible hiccups.

The new environment is now up and running, and after refining the process (poking around a lot), it only takes about 10 minutes to move each host.  This was done on vSphere 5 (moving from vSphere 5 to Update 1).

My Experience: The Synology DS1511+ NAS is Purely Rock Solid

12-26-10-synology-15tb-nasI’ve been running a vSphere lab of my since ESX 2.x.  Over the years, I’ve used both local and NAS based storage with varying degrees of satisfaction with the results.  In the case of NAS storage, which is required since I can’t afford a SAN, I looked at Synology devices over the last year trying to gain the motivation to make the investment.

Needless to say, I dove in with both feet, and maxed out a Synology DS1511+ with 3TB drives.  I purchased my Synology DS1511+ from SimplyNas with the drives included, including their burn-in testing, and I haven’t looked back.  The device has been up and running since October 2011.

Extending The Life of Your VMware vCloud Director Appliance and Changing Certificates

vCloudDirectorVMware is distributing a limited usage vCloud Director virtual appliance to facilitate and support evaluation of the product.  I wanted to stand it up in my lab as a test-bed and to get to know the product better, but after checking into it, it’s not just the eval licenses that will expire.  The http certificates will also expire within 60 days of the certificates being generated since it uses the Java ‘keytool’ utility and it’s configured to.  As a VMware partner and I have access to licenses to extend the life of the appliance but due to my environment, I cannot work with expired certificates.

With the release of VMware vSphere 5, I decided to upgrade my lab from 4.1.  The process was pretty painless for the most part, but I thought I would right a few notes about the experience and a couple of things I did to help my scenario along.

I upgraded 3 vSphere 4 (ESXi) hosts and a virtual vCenter Server.
