Hewlett-Packard has just released a Generation 8 Microserver which is going to replace the well known N36L/N40L/N54L Microservers. The new server has the same trendy design as the entire Gen8 series. The AMD Turion CPU has been replaced by an Intel Ivy Bride CPU which is way more powerful and the memory limit has been raised to 16GB. With that, the new server brings much more power to your VMware vSphere Homelab and allows you to run more virtual machines. In this post i am going to compare both specs to point out what's new and better.
With the separation of the vCenter Service into 4 components in vSphere 5.1 (vCenter Single Sign On, vCenter Inventory Service, vCenter Server and vSphere Web Client) there is a possible issue that you could have mismatched services installed. When you install an update you have to install all components one after another without having a workflow to check that all have been updated. I have already written about the update process from 5.1 to 5.1u1 and their versions but this is not the only update available. Now I've created an overview of all possible vCenter 5.1 version numbers that can be identified in the Control Panel.
About 6 months after the release of VMware vSphere 5.1 the first Update is available since this weekend. As you know, the vCenter Server has been split into 4 services: Single-Sign On, Inventory Service, vCenter Server and the vSphere Web Client. That makes the update process a little bit more more complex. Here is a small Walk-though how to Update to vSphere 5.1.0 U1
Intel uses a model named "Tick-Tock" to follow every microarchitectural change with a die shrink. This results in having two EVC baselines for every microarchitecture. I've created a small table with a quick overview about EVC Modes with their appropriate CPU Series and Codenames used by Intel to denote their CPUs. I've also included additional Codenames that may be used by Intel for special processors. The upcoming Haswell architecture is named, but not yet available or supported by VMware.

Since VMware introduced the vSphere Web Client there is a common question: Which vSphere client should I use? The answer simple: You need both!
There are many new features within vSphere 5.1 which are only available through the Web Client. But there are also many reasons to use the old C# Client: Some features and plugins are not implemented in the Web Client Client. There is no doubt that you need both clients to configure your vSphere 5.1 environment. But which client should you use for day-to-day work or for configuration tasks that are available in both clients?
This post has been updated to include vSphere 5.5 Features
With vSphere 5.1 a new component called Single-Sign-On (SSO) has been introduced. The new SSO service is mandatory since 5.1. There is no way around, you have to use it. The good thing about it is that it has various authentication options and can be deployed in an redundant fashion. Unfortunately it adds a lot of complexity to your configuration but if you understand all of it's components and functions, you won't miss it.
Be careful when updating you ESXi hosts from VMware vSphere 5.0 to 5.1. The following servers were supported in 5.0 but are no longer supported in 5.1:
Within vSphere 5.1 a new feature called Tags has been introduced by VMware. Tags are an enhancement of Custom Attributes and enables users to categorize inventory objects. They are a great approach for organizing or reporting tasks. Tags can be associated to the following object types:
