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).

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.

My vSphere 5 Upgrade – Notes and Lessons

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.

Using the Iomega IX4-200D as a Storage Target for vSphere (ESX and ESXi) Lessons Learned

StorCenter_ix4_200d_hi_328x188

I’ve been using an Iomega IX4-200D as a storage target for vSphere and have to say that for the most part it works well.  I’ve used it both as an iSCSI target and as NFS storage.

You can and should expect it to suffer typical storage performance issues.  It runs on 4 hard drives, mine in a RAID 5 array which is not the most performant, but best in case of disk failure and who wants to lose VMs.  It’s still a limited set of spindles to work with and keeping that in mind will save you troubles down the road.

At one point, I had 17 VMs running on a single IX4-200D.

Still interested?  Keep reading…

ESXi Going Forward, Is It Really All Doom and Gloom?

ESXi vs. ESX – warning, this is a rant! 🙂

I recently participated in a discussion thread on LinkedIn in the VMware Certified Professionals group that got to be a little lively.  In this discussion, outside of the original poster’s question, a side discussion began on ESXi vs. ESX and all the trouble that it entails.  One poster in particular, a former VMware TSE (tech support engineer), really preached doom and gloom about the product’s future with the announced phase out of ESX and transition and continuation of ESXi as the VMware flagship product.

I personally have mixed feelings about the decision.  I love ESX and have been working with the product for years now.  I like the accessibility and control that the service console provides and thus far have been willing to tolerate the overhead of the Console Operating System (COS) and some of the associated problems as a trade-off for the control that it provides.  Apparently there are people that are far more upset about this decision by the powers-that-be at VMware than I am though, and in one case the former TSE even said that he would look forward to seeing people ‘crumble’ when they have problems with ESXi and no console access.  As I’m running this blog, and try to provide information and help to people at their fingertips, I would never wish ill on my fellow techies or the organizations that employ them.  Well maybe a few… <grin>.
