Windows vCenter 5.5 / 6.0 Migration to vCenter Appliance (VCSA) 6.5 U1

Windows vCenter 5.5 / 6.0 Migration to vCenter Appliance (VCSA) 6.5 U1

It is time to think about upgrading “older” vSphere environment to the latest version 6.5 U1. The journey to the cloud, VSAN and lots of other new possibilities as well as the approaching end of support date for vSphere 5.5 (2018/09/19) are more than enough reasons to start planning a vSphere Upgrade. VMware recently announced the official end of Windows vCenter: https://blogs.vmware.com/vsphere/2017/08/farewell-vcenter-server-windows.html Traditionally a lot of customers are still using vCenter on Windows. VMware’s longer term strategy is targeted to…

vSphere Homelab Version 2017

vSphere Homelab Version 2017

Well there are a lot of people having a lot of home lab installations out there. The latest trending home lab servers are Intel NUCs. I started to think about replacing my old PCs I still use as physical ESXi servers. Looking at Intel NUCs is for sure an option. The price is really interesting, but the max mem is 32 GB and they come with one NIC only, and you cannot really put a lot of disk space into…

I hope you know RVTOOLS

I hope you know RVTOOLS

I just noticed that there is a new version of RVTOOLS out. Since years I do use and recommend RVTOOLS to my customers. – I know there are tons of scripting guru’s out there who will get some of the information out of vSphere infrastructure. But RVTOOLS is just the one and only tool every vSphere admin can use with just one click, and everything you ever wanted to know about your vSphere infrastructure will be intelligently grouped in the tool,…

vSAN on vSphere 6.0 and vSphere 6.5 – Upgrade path – there are dependencies..

A few days ago VMware released the new version of vSphere 6.0 Update 3. – As you would expect this version also contains some awesome patches for vSAN, which will make it more stable and more performant. – see the ESXi 6.0 U3 Release notes! Great stuff. – But take care there are dependencies. As there are currently two release tracks of vSphere (6.0 and 6.5) which are updated regularly – there are slight differences in vSAN versions and sometimes…

Some Performance hints for VSAN 6.2

Some Performance hints for VSAN 6.2

With VSAN 6.2 VMware added a lot of new features, like dedup, compression and checksums. Some of these features can use CPU resources to a certain extent – depending on your workload. In my personal experience with customers, I have found that the Checksum option can produce some overhead – especially in All-Flash configurations with extremly high IO, or if you are doing benchmarks (which also produces high IO load normally…) If you are using all-SSD configuration and you can…

vCenter / SSO / PSC 5.1 5.5 and 6.0 mixed versions compatibility

vCenter / SSO / PSC 5.1 5.5 and 6.0 mixed versions compatibility

You have multiple vCenters in different versions and want to upgrade to vCenter 6.0 (U2 or later)? – What is supported and what is unsupported? There are some possible configurations where you can have different versions of SSO compared to your vCenter versions.  This automatically happens during upgrades. There are some combinations that are supported and some combination which are unsupported. Especially re-installing or re-pointing and “old” vCenter to a newer SSO or PSC version is something which is only…

How to keep VMware TOOLS up-to-date?

How to keep VMware TOOLS up-to-date?

Update VMware Tools? You might have heard in autumn 2015 that VMware is de-coupling VMware Tools from virtualisation solutions. This means VMware Tools will be released separately and the latest VMware Tools will be compatible with all platforms, this means the latest VMware Tools will work with Workstation, Fusion, and all ESXi versions (5.X, and 6.X). This is especially useful if you are in an upgrade scenario, with rolling upgrades – so you can update VMware Tools even before you…

Change OS (update from Windows 2008 to Windows 2012 R2) of vCenter 5.5 – Change vCenter 5.5 SSO architecture, virtualize a physical vCenter 5.5

1. Summary The following checklist describes the process of migration (update) the vCenter 5.5 OS (for example from Windows 2008 to Windows 2012 R2) by actually re-installing a fresh vCenter 5.5 – using the exsisting vCenter database, inventory database and certificates. A following step could be to update this “refreshed” vCenter 5.5 to vCenter 6.0. – And yes I am talking about Windows vCenter to Windows vCenter I am not talking about vCenter appliance. I had various questions from customers…
